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.

Download or read book Coping with Water Scarcity written by Luis Santos Pereira and published by Springer Science & Business Media. This book was released on 2009-03-22 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones. This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.

This book was released on 2018-09-22 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2018 in the subject Biology - Botany, grade: A, language: English, abstract: Twenty maize genotypes were tested in alpha-lattice design with two replications in research block of National Maize Research Program, Rampur, Chitwan from February to June, 2016 to evaluate maize inbred lines for their genetic components association among yield components and correlation and stress tolerance indices. Shorter ASI was found in RML-17, RML-57, RL-107, RL-140, RML-91 whereas more leaf area index in NML-2, RML-91, and RML-24 respectively. Inbred lines, RML-91, RML-17, RML-20, RL-140, RL-140, RML-91 and NML-2 were found lower tassel blast and leaf firing percentage respectively. Inbred lines, RML-76, RML-115, RML-4, RL-111 showed slower leaf senescence and RML-57, RL-101, RML-11, RL-107 showed significant higher value of SPAD chlorophyll content. Heritability and correlation analysis revealed that grain yield, number of kernel ear-1, silk receptivity, shelling percentage, thousand kernel weight plant and ear heights showed presence of additive gene effect and those traits direct could be used as direct selection to improve maize grain yield under heat stress condition. With attention to high negative correlation with anthesis silking interval, tassel blast, leaf firing with grain yield the minimum of anthesis silking interval, tassel blast and leaf firing were the most important index required further genotyping for development of thermo-tolerance lines. Cluster and PCA analysis revealed that cluster 4 genotype named as RL-140, RML-76, RML-40 and RML-91 were found to be tolerant to heat stress with higher value of grain yield and other desirable traits and lower leaf firing, Tassel blast and itermediate of anthesis-silking interval which were suitable for cultivation under heat stress condition.Based on stress tolerance indices and their correlation analysis, RML-91, RML-140 appeared as having high yield potential and low stress susceptibility u
