Book excerpt: Maize is a staple cereal after wheat and rice. It is an important source of carbohydrate, protein, iron, vitamin B and minerals for many poor people in the world. In developing countries maize is a major source of income in resource-poor farmers. As maize is used both as silage and as crop residue and the grains of maize are usually used for food, starch and oil extraction industrially, the demand for maize is rising day by day. Therefore, it is imperative for improvement of maize to meet the increasing demand. This book entitled "Maize - Production and Use" highlights the importance of maize and the improved management approaches for improving the productivity of maize in the era of changing climate.

Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is confronted with changing societal expectations and demands regarding its role in food production and in the countryside. Complying with these expectations and demands will require a comprehensive, far-reaching and therefore far from easy and long-lasting transition of agriculture. This books seeks to explore the seeds of this transition by describing and analysing the production of promosing novelties in relation to to the dominant regime. On a theoretical level this books aims at the integration of hitherto largely disconneted disciplines and bodies of literature.

Download or read book Maize Crop written by A. Solaimalai and published by CRC Press. This book was released on 2020-05-10 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is one of the versatile emerging crops with wider adaptability under varied agro-climatic conditions. Globally, maize is known as queen of cereals because it has the highest genetic yield potential among the cereals. It is cultivated on nearly 150 m/ha in about 160 countries having wider diversity of soil, climate, biodiversity and management practices that contributes 36 % (782 m/t) in the global grain production. The United States of America (USA) is the largest producer of maize contributes nearly 35 % of the total production in the world. It is the driver of the US economy. This book talks about the improvement, production, protection and post harvest technology of the maize crop.

Download or read book Endangered Maize written by Helen Anne Curry and published by Univ of California Press. This book was released on 2022-01-25 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Many people worry that we're losing genetic diversity in the foods we eat. Over the past century, crop varieties standardized for industrial agriculture have increasingly dominated farm fields. Concerned about what this transition means for the future of food, scientists, farmers, and eaters have sought to protect crop plants they consider endangered. They have organized high-tech genebanks and heritage seed swaps. They have combed fields for ancient landraces and sought farmers growing Indigenous varieties. Behind this widespread concern for the loss of plant diversity lies another extinction narrative about the survival of farmers themselves, a story that is often obscured by urgent calls to collect and preserve. Endangered Maize draws on the rich history of corn in Mexico and the United States to trace the motivations behind these hidden extinction stories and show how they shaped the conservation strategies adopted by scientists, states, and citizens. In Endangered Maize, historian Helen Anne Curry investigates more than a hundred years of agriculture and conservation practices to understand the tasks that farmers and researchers have considered essential to maintaining crop diversity. Through the contours of efforts to preserve diversity in one of the world's most important crops, Curry reveals how conservationists forged their methods around expectations of social, political, and economic transformations that would eliminate diverse communities and cultures. In this fascinating study of how cultural narratives shape science, Curry argues for new understandings of endangerment and alternative strategies to protect and preserve crop diversity"--

Download or read book Sustainable Intensification written by Jules N. Pretty and published by Routledge. This book was released on 2012-06-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Yield Formation in the Main Field Crops written by V. Cerný and published by Elsevier. This book was released on 2012-12-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a detailed overview of production processes and yield formation in field crops and permanent grasslands. Yield formation is discussed by the authors as a dynamic process, involving many factors at each stage. Knowledge of the optimum levels of individual yield components makes it possible to control this dynamic process. It is intended that this approach will help to point out gaps in the understanding of the production processes and indicate the direction for further research on this subject.The authors report on various aspects which are involved in yield formation, such as uptake of nutrients, root growth, water use, photosynthesis, transport, distribution and accumulation of photosynthates, etc. A separate chapter discusses the production process as seen from a genetic standpoint. It includes an analysis of phenotype and genotype with respect to production potential, also the heredity, variability of yield potential and new cultivation methods are mentioned. The main part of the book deals with the theory and practice of yield formation in cereals, maize, legumes, sugarbeet, potatoes, clovers and perennial grass stands.

Download or read book Relationships Between Cropping Practices Soil Quality and Maize Zea Mays L Yield in Morogoro Region Tanzania written by Steven Anthony Doyle and published by . This book was released on 2018 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize (Zea mays L.) is the principal food source for Eastern Africa’s rising populations. In Morogoro Region, Tanzania, 56% of agricultural land is cropped with maize and 90% of its people are smallholder farmers. For these reasons, understanding the relationship between crop management decisions, agricultural soil quality, and maize yield is of critical importance. Field management practices were recorded during the November – January (short) rainy season crop, and the March – June (long) rainy season, and water use during the short rainy season. Soil samples were taken from each field in June 2017 and analyzed for soil quality parameters pH, total nitrogen (TN), soil organic carbon (SOC), bulk density (BD), texture, aggregate stability (AS), and penetration resistance. Analyses indicated that during both the short and long rainy seasons, maize production resulted in a lower pH than in vegetable production, or maize – cowpea intercrop. Fields which were cropped with maize in the long rainy season had higher clay content (Clay) than did those cropped with a maize – cowpea intercrop. Sand content (Sand) appeared to be higher in fields cropped with a maize – cowpea intercrop in maize in the long rainy season. Textural variation was accounted for a spatial gradient in soil series, which likely informed crop choice. Aggregate stability was found to be higher in fields cropped with maize in the short rainy season than with vegetable. TN, SOC, BD, silt content (Silt), and penetration resistance were not found to vary between crop management practice. Each soil quality parameter was entered into a linear regression model and a mixed effects model with long rainy season maize yields to determine the property’s association with maize production. These analyses indicated that BD and sand concentration were negatively affecting maize yields while silt concentration, and to a lesser extent, SOC and AS were positively affecting maize yields in the sampled fields. From these findings, farmers would be advised to increase their SOC through manure or cover crop incorporation, while decreasing tillage rates. They may also be advised to cultivate maize on soils with higher Clay and vegetables on soils with higher Sand.

This book was released on 2021-02-03 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2021 in the subject Agrarian Studies, grade: 1, , course: Agriculture, language: English, abstract: A field experiment was conducted during 2019 main cropping season at Boloso Sore district with the objective of evaluating different maturing varieties and row spacing on yield and yield components of maize. Four row spacing (50, 65, 70 and 80 cm) and three maize varieties (BH-540, BH-543 and BH-547) were tested in factorial arrangement laid out in RCBD replicated three times.This work analyses the study and presents its results. Maize is one of the most important cereal crops in the world. It ranks third in world production after wheat and rice. Ethiopia is the fourth largest maize producing country in Africa, and first in the East African region in terms of production. Presently maize is widely grown in most parts of the world over a wide range of environmental conditions ranging between 50o latitude north and south of the equator. Maize is an important field crop in terms of area coverage, production and utilization in Ethiopia. It ranks second in area coverage (after teff) and first in total production among cereals. It is grown for its food and feed values and one of the most important staples and cash crops and the main sources of calories. In view of its high demand for food grains and high yield per unit area, maize has been among the leading food grains selected to achieve food self-sufficiency in Ethiopia.The major maize producing regions in Ethiopia are Oromia, Amhara, and SNNPRS in descending order. The national average productivity of maize was 4.09 ton ha-1. In SNNPRS, maize ranked first in terms of area coverage and production among cereals and its average yield was 3.93 ton ha-1. Wolaita zone is one of the most important maize producing zones in SNNPR State. According to CSA report, at Wolaita zone, maize is the first leading crops among cereals in area coverage, and its zonal average yield was 3.01 tha-1.
