This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

Genre: Gardening
ISBN: 1845937538

This volume consists of two parts. Part 1 comprises 6 chapters concerning the principles and practice of tropical vegetable production (including site, topography, soils and water; site management, seeds and types of cultivars; support for farmers; crop preparation and management; reducing pre- and postharvest losses and marketing surpluses). In Part 2, the crops have been mainly dealt with according to their taxonomy as botanical families, either as single or groups of families per chapter. These include: Alliaceae; Cruciferae [Brassicaceae]; Cucurbitaceae; Solanaceae; Leguminosae; leafy vegetables; Araceae, Convolvulaceae, Dioscoreaceae, Euphorbiaceae; Andean tubers and roots and crops of the Lamiaceae and Apiaceae; and Gramineae [Poaceae] and Cyperaceae. Examples of the indigenous species which can be regarded as important sources of edible vegetative materials which are not dealt with in the main text have been listed in Appendix 1. Contact details of the main international research stations are provided in Appendix 2. This book has been written with the hope and purpose that it will be used by technical, college and university students during their studies of horticulture, crop production and agriculture; it is also for students on other allied courses and agriculturists who find themselves needing more vegetable-orientated information in the course of their professional activities. It is aimed to assist in the production of extension, advisory and research staff and officers who will be the core of trainers, advisors, researchers and extension workers in tropical and subtropical countries.

This book showcases the power of economic principles to explain and predict issues and current events in the food, agricultural, agribusiness, international trade, natural resources and other sectors. The result is an agricultural economics textbook that provides students and instructors with a clear, up-to-date, and straightforward approach to learning how a market-based economy functions, and how to use simple economic principles for improved decision making. While the primary focus of the book is on microeconomic aspects, agricultural economics has expanded over recent decades to include issues of macroeconomics, international trade, agribusiness, environmental economics, natural resources, and international development. Hence, these topics are also provided with significant coverage.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
