Metal pollution
The increase in built-up areas in the coastal zone, particularly in Conakry and the secondary towns, clearly indicates that the prospects for demographic growth are strong. Sources of hydrocarbon and heavy metal pollution in Guinea come from industrial zones, seaports, navigation areas and thermal power stations.The aim of this study was to assess the level of contamination of a number of fish species by trace metals (TMEs) in Tabounsou Bay.The samples were analysed by Uviline spectrophotometry at the physicochemical laboratory of the Office National de Contr繫le de Qualit矇 de Matoto (ONCQ), and the results were compared with those of the standard accepted by the EC/2001 and FAO/WHO (1989) and other authors.
Water productivity in the dairy sector in Southern Coahuila, Mexico
The objective was to determine the productivity (P) and efficiency (E) of water (A) used in bovine milk production, both in physical (F), economic (E) and social (S) terms in the Rural Development District (RDD) Laguna-Coahuila, Mexico in low (LRV) and high yielding (HRV) dairy herds, using an economic methodology based on the use of mathematical equations fed with commercial scale data. The results, for both types of producing wombs, in the same order, showed the following indexes: PFA 0.385 and 0.6864 liters of milk per m3 of water, PEA had USD 12,731 and USD 22,698 of profit per hm3 of water, PSA was the same index in both wombs 1.059 Jobs per hm3, its inverse, the efficiency indexes of water used in production, were as follows: 2,600 and 1,459 liters of water per liter of milk in the EFA, while in the EEA there were 78.55 and 44.06 m3 for each USD of profit, and in the PSA it was the same indicator 944,273 m3 for each job generated.
Evaluation of an irrigation system in areas cultivated with pastures
Evaluating the efficiency and uniformity of irrigation systems at field level helps to mitigate the losses that occur during and after the application of water by the system. The aim of this study was to evaluate the performance of a mesh sprinkler irrigation system installed in a pasture area with Brachiaria and Tifton 85 grass in the municipality of Fortaleza - CE. The system's water application uniformity was estimated using the Christiansen Uniformity Coefficient (CUC), the Distribution Uniformity Coefficient (CUD) and the Statistical Coefficient (CUE). On the basis of the values found, it can be concluded that the irrigation system evaluated is impaired, since all the performance parameters evaluated showed low values, classified as poor when compared to those recommended in the literature.

Castor bean
The castor bean (Ricinus communis L.) is an oil plant with considerable economic potential, whose main products or by-products of agricultural importance are oil and cake. The castor bean adapts to almost all types of soil, but it is recommended that it be grown on soils of medium to high natural fertility. Chosen as one of the oilseed crops to supply raw materials for biodiesel production in Brazil, castor bean is economically and socially important because it is a crop that is viable for family farming. This book arose from the collection of various studies carried out on the castor bean in order to investigate its agronomic characteristics and boost its development and production in the semi-arid region of the Northeast. In this way, this book brings relevant contributions with information that indicates the excellent potential that castor bean has to be cultivated under appropriate fertilization and irrigation conditions in order to obtain good production, providing family farmers with an additional alternative for planting on their land.
Action of Insecticides and Fungicides Used on Tomato Crops
The aim of this study was to evaluate the effect of the main pesticides registered for tomato cultivation on the parasitism of the egg parasitoid Trichogramma pretiosum. 29 fungicides and 30 insecticides were evaluated for their selectivity. The insecticides and fungicides were separated into toxicological classes according to the reduction in parasitism capacity, according to the scale proposed by members of the IOBC/WPRS.
Seed treatment, herbicides, air temperature in irrigated rice
Sowing time is one of the main factors to be taken into account when obtaining high yields in irrigated rice. However, when sowing is carried out early, low temperatures can cause stress to the crop, reducing its speed of emergence and plant stand, as well as reducing the selectivity of the herbicides applied. Seed treatment can be an alternative to increase the speed of rice emergence and improve selectivity to herbicides in the initial phase of crop development. In view of the above, the objectives of this work were to: to carry out a literature review on seed treatment (Chapter I); to evaluate the effect of seed treatment on the germination and initial establishment of irrigated rice seedlings at different sowing times and on herbicide selectivity (Chapter II); to characterize the biochemical parameters of oxidative stress in irrigated rice subjected to low temperatures and the application of herbicides (Chapter III); and to evaluate the initial performance resulting from the application of fertilizers on herbicide selectivity in irrigated rice cultivation.
Spodoptera frugiperda (J. E. SMITH) and Helicoverpa armigera (H?BNER)
In Brazil, agriculture occupies large areas, and despite extensive cultivation, average productivity per hectare is still very low. Pests are mainly responsible for the reduction in production. Among the main pests that attack agricultural crops, we can mention the caterpillars Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and Helicoverpa armigera (H羹bner) (Lepidoptera: Noctuidae), as the pests that cause the greatest economic damage to the main agricultural crops in Brazil. This book describes the species, methods of identification, breeding and control.
Initial soil preparation - Principles
The book covers the set of operations needed to turn an agricultural area with natural vegetation into an area that can receive crops of economic interest without damaging the soil and the legislation in force. To this end, it covers environmental protection areas, methods of deforestation, clearing, harrowing and leveling the soil, as well as the necessary equipment, with an emphasis on its uses and limitations.
Seed physiological quality
The physiological quality of seeds is normally assessed by standard germination and vigor tests. However, in batches with a high degree of heterogeneity, these tests can have low sensitivity, and it is necessary to obtain reliable results in a short period of time, ensuring rapid decision-making in relation to the physiological quality of seeds. With this in mind, the aim of this study was to separate batches of soybean, bean and corn seeds in terms of vigor, using respiratory activity. To this end, three batches of seeds from these crops were subjected to standard viability and vigor tests, such as germination, first germination count, germination speed index, electrical conductivity, seedling emergence and emergence speed index in the greenhouse, length and dry mass of the aerial part and roots of the seedlings from the germination and seedling emergence tests and respiratory activity.
PHENOLOGY OF FIG (Ficus carica L.) WITH INDUCED HYDRIIC DEFICIT INDUCED
The fig tree (Ficus carica L) is a crop that despite being very remote and used for a long time as a non-commercial species, has been gradually taking place in world production. Mexico has climatic conditions and advantages to become an important producer internationally, however, its annual production is low and this could be due, among other things, to the little information and experimentation on the influence of irrigation on the production of this species. Worldwide, research has been done on water deficit on yield and fruit quality, but the influence it has on the phenological development of the crop has been ignored. The objective of this research was to evaluate the phenology of vitroplants and plants per fig stake with water deficit induced by drip irrigation in greenhouse with a 3x2 factorial arrangement resulting in 6 treatments; T1 In vitro 2.3 mm/day, T2 Stake 2.3 mm/day, T3 In vitro 1.7 mm/day, T4 Stake 1.7 mm/day, T5 In vitro 1.1 mm/day, T6 Stake 1.1 mm/day.

Physiology of tree species as a function of water supply
The current climate change scenario has intensified the problem of water availability in arid and semi-arid regions around the world. As such, the implications of these changes for tropical forests have been the subject of a great deal of research around the world. One of the main concerns is the reduction in water availability, which is the main factor influencing plant productivity in the tropics. This book provides a comprehensive analysis of the physiological and growth parameters of forest species under different water regimes. This information can be used to help select species adapted to conditions of low soil water availability.
Performance of washing equations for recovering salinized soil
In regions where irrigation is intensive in order to increase crop production, fertigation is widely used as an alternative to fertilization, providing a lower degree of risk. However, the excessive application of fertilizers via fertigation can increase the risk of soil salinization, especially due to the indiscriminate application of fertilizers. Rainfall in open fields is not always enough to wash salts out of the soil. The volume of water needed to flush a soil profile is calculated according to the initial salinity of the soil, the desired final level, the type and depth of soil to be flushed, the method of application of the irrigation water and the concentration of salts in the flushing water. The aim of this work was to evaluate the performance of empirical equations for the recovery of salinized soil, in a continuous and intermittent leaching system, in the case of fertilizer salt wash water.
Chlorophyll content at the end of the caupi bean cycle in partnership with
The chlorophyll index present in cowpeas in the final phase of production was evaluated in an experiment carried out in the experimental area belonging to the Agricultural Engineering department of the UFC, in Fortaleza - Ce, Brazil, with an experimental design in randomized blocks and subdivided plots, the plots being made up of the treatment of different blades in relation to the evaporation of the class A tank (ECA) ( 0.25; 0.50; 0.75; 1.00; 1.25 times the ACE) and the sub-plots were made up of the treatment times for transplanting the grass (0; 5; 10; 20 DAEF - Days after bean emergence. ), with each treatment comprising three replicates. Observing the effect of the blades evaluated, those equivalent to 0.75 and 1.00 times ECA stood out, which showed the highest chlorophyll index in the Caupi bean leaves. As for the weed insertion time treatment, the 10 and 20 DAEF times stood out, showing that the legume's competition with the grass directly affects chlorophyll production in the bean plant.
Mapping areas vulnerable to pesticide contamination
The exploitation of forests and natural resources to expand agricultural activities, while promoting economic development and meeting the demand for human food, causes environmental impacts that must be quantified, discussed and mitigated. The use of pesticides to increase productivity and combat pests and pathogens can cause environmental changes to the environment in which they are used. The soil is the ecosystem that retains the most contaminants; over time, pesticides weaken it and reduce its fertility. They can also lead to the death of mycorrhizae, reduce soil biodiversity, cause acidity, run off into watercourses, streams and rivers, among other problems reported and discussed here with a view to using Geographic Information Systems (GIS) tools as suggestions for solutions and guidance for public policy attitudes in Brazil, aimed at the rational use of soil, conservation and preservation of natural resources. Therefore, based on geotechnologies, this work aims to address the management of land use and occupation through map algebra in the mapping of areas in the Brazilian cerrado.

Propagation of damas plant (Conocarpus lancifolius)
Conocarpus is a new crop for the Gujarat region. It is very much popular herebecause of its hardy nature. It is excellent for landscape planting, for creating screening effect and reduces noise pollution. Looking into the importance of the plant, this experiment is to be carried out to standardize the proper propagation technique for nursery man. Regeneration of roots in cutting is basically a problem of growth and differentiation at the cellular level and is largely controlled by internal factors including hormonal and nutritional status of the cutting. The root promoting hormones contribute significant role to the process of regeneration of roots in the cuttings and their survival. Indole-3-butyric acid (IBA) plays a key role in both root and shoots development. The plant growth regulators have been reported to stimulate the formations of roots in propagation material. Specific concentration of IBA is required to start production in rooting of plant.
Study on Transportation Losses of Sapota
The study focused on reducing transportation losses of sapota using different containers. Conducted in 2010 at Junagadh Agricultural University, it involved grading, sorting, and transporting sapota in various containers.

Good Nature
A Next Big Idea Club must-read selection! An Amazon Editor's Pick for Best Nonfiction Book! A ground-breaking investigation into newly discovered evidence showing that remarkable things happen to our bodies and our minds when our senses connect with the natural world. We all take for granted the idea that being in nature makes us feel better. But if you were a skeptical scientist--or indeed any kind of skeptic--who wanted hard scientific evidence for this idea, where would you look? And how would that evidence be gathered? It wasn't until Dr. Kathy Willis was asked to contribute to an international project looking for the societal benefits we gain from plants that she stumbled across a study that radically changed the way she saw the natural world. In the study there was clear proof that patients recovering from gall bladder operations recovered more quickly if they were looking at trees. In fact, in the last decade there has been an explosion of "proof" that incredible things happen to our bodies and our minds when our senses interact with the natural world. In Good Nature, Kathy Willis takes the reader on a journey with her to dig out all the experiments around the world that are looking for this evidence--experiments made easier by the new kinds of data being collected from satellites and big-data biobanks. Having a vase of roses on your desk or a green wall in your office makes a measurable difference to your well-being; certain scents in room diffusers genuinely can boost your immune system; and, in a chapter that Kathy calls "Hidden Sense," we learn that touching organic soil has a significant effect on the healthiness of your microbiome. What is remarkable about this book is how its revelations should be commonsense--schools should let children play in nature to improve their health and concentration; urban streets should have trees--and yet it reveals just how difficult it is to prove this to businesses and governments. As Kathy Willis says in her narrative, "We now know enough to self-prescribe in our homes, offices or working spaces, gardens, and when out walking. However small these individual actions might be, overall they have the potential to provide a large number of health benefits. And we need to be encouraging others to do the same. Nature is far more than just something that is useful for our health. It is not a dispensable commodity. It is an inherent part of us."

The book is aimed at university students studying Irrigation and Drainage Technology, Agricultural Engineering and Agronomy, among others.
Effectiveness of entomopathogenic fungi for management of sucking pest
The fungus Beauveria bassiana (Ascomycota: Hypocreales) is a generalist (broad-spectrum host range) insect pathogen able to infect nearly 1000 insect species. As for other entomopathogenic fungi of the order Hypocreales, the main route of infection for B. bassiana is the penetration of the insect cuticle, which represents the first encounter and barrier between the fungus and host. Upon the adhesion to and recognition of the insect surface, B. bassiana deploys a combination of biochemical and mechanical tools to make its way through the insect integument into the hemocoel. Once the fungus reaches this nutrient-rich environment, the mycelium switches to a specialized yeast-like cell phenotype; in invertebrate pathology, they are often referred as hyphal bodies or blastospores when they are produced artificially in culture media. At this stage, the insect host has very little chance of surviving the fungal infection despite the activation of the immune response (humoral and cellular) as a last-ditch attempt to overcome the fungus.
Seedlings of sunflower cultivars produced with waste
The sunflower is a crop that provides a great composition in gardens, as well as having various uses and qualities, and can even be used as biofuels, in other words, reducing pollution and mitigating the environmental impacts caused by burning fossil fuels. In order to produce sunflower seedlings, it is necessary to use a substrate, which requires an initial outlay to fund production, and it is also important which type of substrate provides the best conditions for the development of this crop and its various varieties. As there is a large amount of waste produced in the agro-industry, it can be reused as organic substrate, providing nutrients, saving money for small farmers and providing a viable and sustainable alternative for agricultural production.
Conservationist Agriculture
Fertilization is an agricultural practice that consists of applying fertilizers to the soil to recover or conserve its fertility. It is possible to supply the lack of soil nutrients and provide adequate development of cultivated plants, increasing productivity.In recent years it has been recognized that fertilization can be conducted on the basis of new strategies. One of the bases of innovation in fertilization is the continuous scientific research on the efficiency of new agricultural management techniques.The soybean crop, one of the key crops to the United States, China and Brazil, demands significant amounts of fertilizers, especially phosphates. Brazil is the fourth largest consumer of fertilizers in the world, representing around 6.0 % of world consumption, behind only China, India and the United States.In some crops, such as cotton, the cost of fertilizer is 30 % of the total cost of production, leading farmers to adopt practices that increase the efficiency of fertilizers in intensive grain and fiber production systems.
Mushrooms
There are around 1.5 million fungal species worldwide. Out of these around 14,000 species produce fruiting bodies known as mushrooms, and around 2000 species are edible, and only 270 are reported to be medicinal. The fungal kingdom is phylogenetically closer to humans than plants, so gives better health benefits to human systems.This book educates readers on the nutritional, pharmaceutical and medicinal values of different mushrooms and their utilization as nutraceuticals and functional foods for human security. It reviews the current knowledge on the distribution of edible mushrooms, its general characteristics, morphology, nutritional profile and properties, pharmacological importance, and biological activities. Health benefits of mushrooms, antioxidant and secondary metabolite profiling, major biological activities of mushroom-derived secondary metabolites, functional foods based on the mushrooms open doors for therapies, products with added value, toxicology, and side effects if any are also highlighted.The book is intended for a large and varied audience - researchers, scientists, and scholars in academia, mushroom growers and industries, nutritionists, dietitians, food scientists, clinicians, doctors, drug industries, pharmacy, biotechnologists, biochemists, botanists, mycologists, and general masses.

Interaction between arbuscular mycorrhiza and manganese in sabi獺 seedlings
Mineral exploration is considered one of the main anthropogenic actions that cause soil pollution with metals, including manganese, which when in excess can cause toxicity symptoms, inhibit plant growth and cause changes in plant communities. The search for alternatives to minimize this type of impact is therefore necessary. A recent and very promising technique that has been used is phytoremediation, which basically consists of using plants to absorb and accumulate heavy metals. In this context, the use of plants associated with arbuscular mycorrhizal fungi can improve the absorption of water and nutrients, as well as aiding plant development in adverse locations and helping to reduce the availability of heavy metals. The aim of this study was to evaluate the effects of mycorrhizal inoculation on the development of sabi獺 seedlings in soils impacted by manganese mining.
Characterization and impacts of different uses of an Argissolo
Soil management and use are of fundamental importance for the balance of its physical, chemical and biological characteristics, acting directly on its productive capacity. The intensity of soil degradation varies according to the ways in which it is used and the types of use and occupation of the area. The aim of this study was to evaluate the influence of different land uses (native forest, pasture and conventional corn planting) on the physical attributes of an Argissolo. It is a study that presents interesting results regarding the monitoring of soil quality in different use systems.

All insecticides are control of a broad spectrum of both chewing and sucking insect pests.all pests become paralyzed and eventually die, insecticide are chemical based properties inhibits Acetylcholinesterase (AChE) &Ecdysone receptor.Protein Acetylcholinesterase is the part of insect nervous system. To inhibit it, many insecticides has been used. Thaicloprid 21.70 sc, spinosad 45 sc, chlorantraniliprole 18.50 sc, fenopropathrin 30 ec, pyridalyl 10 ec, cyantraniliprole 10.26 od, lambda-cyhalothrin 4.90 cs this all of thrm, general used insecticide. But it causes side effects and toxic effects on other animals and soil. So, Phytochemical alternates of insecticides are derived from natural compound database and analysed for ADMET properties. By analysis they proved non toxic an has no-violation in environment. Some of them which has high binding affinity are derived for further analysis.
Farmers-led Autonomous Adaptation Strategies to Climate Change
The book described and appraised farmer-led adaptation strategies to climate change in eastern Uttar Pradesh, India. Farmers of eastern Uttar Pradesh perceived the changing climatic scenario and its impact on crop farming as well as livestock rearing. Total 9 and 15 farmers-led adaptation strategies were documented for crop-farming and livestock-rearing, respectively. In all overall, 'crop diversification' and 'use of shed for cattle and buffaloes' were the most preferred adaptation strategies in crop farming and livestock rearing, respectively. Farmer-led adaptation strategies in crop farming and livestock rearing were appraised in terms of their effectiveness to cope up with the changing climatic scenario. In crop-farming, 'preparation of bunds to control water flow' was most effective adaptation strategy. In livestock-rearing, the most effective adaptation strategies were 'proper sanitation practices for animals', 'regular vaccination' and 'use of jute cloth to cover animals'.
Diachasmimorpha longicaudata
Fruit flies are probably the main pests of fruit growing worldwide. Far beyond the guava bug joke, this insect is responsible for a huge amount of annual losses. With the awakening of a new class of consumers, concerned about the health of the products they consume, there has been a need to reduce the use of industrialized chemical pesticides. Biological control has become an important tool in integrated pest and disease management programs. For the control of fruit flies, native parasitoids have not shown the efficiency that would be appropriate in Brazilian orchards, especially in Rio Grande do Sul. One alternative has been to import and release the exotic species Diachasmimorpha longicaudata. This book is the culmination of 12 years of studies on fruit flies. It is the result of a doctoral thesis that presents data on the first releases of this braconid in southern Brazil. We hope it will be useful to students and researchers in the field. Happy reading.
Impact of Agromet Advisory Services on Farmers' Operational Decision
Changes in essential meteorological factors such as temperature, rainfall, cloud cover, and wind speed impact a farmer's decision in crop management such as land preparation, seed sowing, fertilizer application, plant protection measures, harvesting, storage, and transportation as well as in livestock management in operation such as feed management, shelter management, vaccination schedule, reproductive management, and water management. Therefore, this book describes farmers' perception towards agromet advisory services, to assess the impact of agromet advisory services on farmers' decision-making for different farm operations and to obtain the feedback associated with accessibility and usability of agromet advisory services. The study revealed that there was significant treatment effect on the farm operations such as land preparation, seed sowing, scheduling of irrigation, fertilizer application, and spray scheduling of pesticides and herbicides in banana, vegetable, and coconut cultivation followed by the experimental group farmers.

The results of the study will be helpful to the researcher, social scientists, activists, administrators, policymakers, and students for their review and policy implication of the new rules and regulations for the better implementation of MGNREGA.
Feed and Cure on Mushrooms in Cameroonian Forests
Using beautiful photos and meticulous descriptions, the book "Feed and Cure on Mushrooms in Cameroonian Forests: Stop Hunger and Chronic Diseases by eating Mushrooms" presents different species of edible and medicinal mushrooms of Cameroonian forests. This manual is the first guide on species of wild edible and medicinal mushrooms to harvest while trekking in Cameroonian forests. They include nearly 20 Termite mushrooms, more than 30 Forest or symbiotic mushrooms, more than 100 wood and litter mushroom species. Medicinal mushrooms are nutritional powerhouses with a myriad of health benefits including: decrease cancer risk, lower sodium intake, promote lower cholesterol, protect brain health, provide a natural source of vitamin D, stimulate healthier gut and support a healthy immune system. Edible mushrooms equally activate natural killer-immune cells, thereby increasing human body's ability to fight numerous infections, to stop the growth or progression of tumors and manage neurodegenerative diseases. This book targets mushroom lovers and growers, foresters, graduate students, researchers, teachers and the grand public.
