In this comprehensive manual on soil management, Neal Kinsey explains in thorough detail the workings of micronutrients, organic matter, and soil structure in improving soil fertility and crop production.
This new edition covers genetics and breeding, crop growth and yield, irrigation and fertilization, fruit ripening and quality, and postharvest biology and handling. Updated throughout and now in full colour, it also includes a new chapter on organic tomato production.
Soil productivity maintenance is a major constraint of tropical agriculture system. Crop cultivation is usually moved between fields to utilize only fertile soils for some years without use of fertilizers. However, this cannot be sustained to meet increased demand of an increasing population. Most tropical soils and forests are deficient in nitrogen and phosphorus nutrients and uptake of these limited quantities of nutrients by plant roots from litter is difficult. Soil fertility and plant nutrition are essential aspect of cropping system and these include an adequate supply of essential nutrients for soil productivity, plant nutrition and qualitative crop yield. The availability of these nutrients to plant contributes a lot to its growth and yield. Deficiency of mineral elements essential for plant crop is evident in poor yield and yield quality. An adequate supply of mineral elements is of importance in the tropics where the soil is poorly formed and continuous cropping is on the increase. For any sustainable crop production, soil fertility amelioration is essential. Thus, the application of fertilizer for amelioration of soil fertility is an integral part of suitable production.
I recommend this work for policy makers and research institutions to use as a reference for further research works. And included their package in crop production and soil management practices. This kinds of work not only refine the polices but also save significant amount of foreign money that had been used to purchase inorganic fertilizer which might not be necessary in the near term. It also provide an alternative options for solid west management activities.
The Book ´ Human-wildlife Conflict´ explores and explains the extent which the conflict between the local farmers and wildlife species in farmlands in Cameroon is identified as one of the most critical threats to many wildlife species and the ecological systems. Some of the methods like toxic pesticides used by the local farmers to kill and deter wildlife from crop-raiding are ecologically unacceptable. These pesticides are believed to have killed some of this wildlife species especially the rodents, snakes, monkeys and birds and rendered the surrounding fresh water ecosystem to these farms polluted through surface run-off during heavy rainfall. The Book further explains the consequences of wildlife population decline and extirpation of some wildlife species in some parts of the country if the state government and the conservation stakeholders fail to mitigate this conflict by protecting the animals and crops in the farms through incentives, compensations, and extensive education to the farmers on the disadvantages of using very toxic pesticides in local farms to kill and deter crop-raiders.
Increase in world population, extreme weather conditions, decrease in fresh water supplies, and changes of dietary habits are major issues that affect global food security. We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications will include the improvement and use of genetic resources; crop management and diversification; diffusion of improved varieties; development of cropping systems; sustainable cropping systems for areas prone to environmental degradation; use of agro-ecological data for crop production forecasting; and networks for regional coordination, and data exchange. The impetus behind this book is to bring attention to a cropping system that bears direct relevance to sustainable agriculture and food security. ´´Underutilized´´ crops are found in numerous agricultural ecosystems and often survive mainly in marginal areas. It is timely to review their status because, in recent decades, scientific and economic interests have emerged which focus on lesser-known cultivated species. Underutilized crops have a great potential to alleviate hunger directly, through increasing food production in challenging environments where major crops are severely limited. ´´Global Perspectives on Underutilized Crops´´ is therefore topical and highlights the unmet agricultural challenges that we face today. This book is an important resource for students and researchers of crop science and agricultural policy makers.

This open access collection of papers offers technical analyses, policy recommendations and an overview of success stories to date. Each carefully selected paper provides valuable insights for improved policy making and defines relevant strategic priorities on Africa´s sustainable transformation process, which is in line with the international development agenda. Although agriculture remains the main source of income for Africa´s population, the sector is rain-fed subjecting it to the vagaries of weather and climate change. This volume demonstrates the rationale of developing a competitive, inclusive and sustainable agribusiness sector for Africa´s food security and structural transformation. From the impact of Bioenergy crop adoption and Drought Index Insurance to Agro-Industrialization, this volume is important reading for individual researchers, academic associations and professional bodies interested in African agricultural development.
In any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other´s survival and also provide for sustenance in stressful environment. Agro-ecosystems of many regions around the globe are affected by multi-stress. Major limiting factors affecting the agricultural productivity worldwide are environmental stresses. Apart from decreasing yield they introduce devastating impact on plant growth as well. Plants battle with various kind of stresses with the help of symbiotic association with the microbes in the rhizosphere. Naturally existing plant-microbe interaction facilitates survival of plants under these stressful conditions. Rhizosphere consists of many groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes which assist plants in coping with multiple stresses and in plant growth as well. These microbes help in stress physiology of the plants and can be extremely useful in solving agricultural as well food security problems. The proposed book is split into two parts, with an aim to provide comprehensive description and highlight a holistic approach. It elucidates various mechanisms in rhizosphere of nutrient management, stress tolerance and enhanced crop productivity. The book discusses rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health. Both volumes of the book addresses fundamentals, applications as well as research trends and new prospects of agricultural sustainability. Volume 2: Nutrient Management and Crop Improvement, contains chapters which cover a broad overview of plant growth promoting activities of microbes. This proposed book also highlights the contribution of nitrogen, phosphorus, potassium, iron and zinc-solubilizing microbes from rhizospheric soil to develop efficient indigenous microbial consortia to enhance the food and nutritional security. With the given content and layout the proposed book will be an all-inclusive collection of information, which will be useful for students, academicians, researchers working in the field of rhizospheric mechanisms, agricultural microbiology, soil microbiology, biotechnology, agronomy and sustainable agriculture and also for policy makers in the area of food security and sustainable agriculture. It will be of special interest to both academics and professionals working in the fields of microbiology, soil microbiology, biotechnology and agronomy, as well as the plant protection sciences. Timely, this edited and research book provides an essential and comprehensive source of material from basic to advance findings on microbes and their role in agricultural and soil sustainability.
Rice is the source of livelihood for hundreds millions of households around the Globe. Several Asian and African countries are highly dependent on rice as a source of food and foreign exchange as well as government revenue. Global rice production must increase by 36 per cent by 2025 to feed estimated 4 billion rice consumers. But the rice production is limited by both biotic and abiotic stresses of which insect pests alone caused about 25 per cent losses. Rice leaf folder is considered second economically important insect after the stem borer. Of all insect control methods, the planting of pest resistant varieties is the most effective. Biochemical studies will be helpful in confirming the physiological antibiosis of the new germplasm. Weather factors are the major regulating causes for the insect pest populations under field circumstances. Effective crop protection is an integral component of efforts to increase and sustain rice, O. sativa yields. Many national and international organizations and farmer groups are promoting Integrated Pest Management. IPM uses pest-resistant varieties and biochemical bases of resistance and that´s why can provide enormous benefits to rice farmers.
In any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other´s survival and provide sustenance in stressful environments. Agro-ecosystems in many regions around the globe are affected by high temperatures, soil salinity/alkalinity, low pH and metal toxicity. High salinity and severe draught are other major constraints affecting agricultural practices and also plants in the wild. A major limiting factor affecting global agricultural productivity is environmental stresses. Apart from decreasing yield, they also have a devastating impact on plant growth. Plants battle with various kind of stresses with the help of symbiotic associations with the rhizospheric microbes. Naturally occuring plant-microbe interactions facilitate the survival of plants under these stressful conditions. The rhizosphere consists of several groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes that assists plants in coping with multiple stresses and also promote plant growth. These efficient microbes support the stress physiology of the plants and can be extremely useful in solving agricultural as well food- security problems. This book provides a detailed, holistic description of plant and microbe interaction. It elucidates various mechanisms of nutrient management, stress tolerance and enhanced crop productivity in the rhizosphere, discussing The rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health. Divided into two volumes, the book addresses fundamentals, applications as well as research trends and new prospects for agricultural sustainability. Volume 1: Stress Management and Agricultural Sustainability, includes chapters offering a broad overview of plant stress management with the help of microbes. It also highlights the contribution of enzymatic and molecular events occurring in the rhizosphere due to plant microbe interactions, which in turn help in the biological control of plant disease and pest attacks. Various examples of plant microbe interaction in rhizospheric soil are elaborated to facilitate the development of efficient indigenous microbial consortia to enhance food and nutritional security. Providing a comprehensive information source on microbes and their role in agricultural and soil sustainability, this timely research book is of particular interest to students, academics and researchers working in the fields of microbiology, soil microbiology, biotechnology, agronomy, and the plant protection sciences, as well as for policy makers in the area of food security and sustainable agriculture.
