the objective of this study was to compare non-parametric stability procedures, and to apply different non-parametric tests for genotype × environment interaction (g×e) on seed yield data of 17 chickpea genotypes grown during 2004-05 growing seasons in 10 rainfed environments in iran. the non-parametric measures used for g × e interaction were highly significant (p

the dragon's head(lallemantia iberica f. & c. m.) can be introduced as a new oilseed crop to cold rainfed areas because of its unique characteristics. the field trial was carried in a split-plot factorial in a randomized complete block design (rcbd) with three replications in dryland agricultural research institute (dari) in 2010-11. the treatments included three landraces of dragon’s head...

A field experiment was conducted during the seasons of 2010/2011 in a semiarid savannah zone, at the faculty of agriculture demonstration farm University of Zalingei two kilometers east of Zalingei town Western Darfur State. The aim of the experiment is to study the effect of weed control on growth and seed production of (Clitoria ternatea) under rainfed conditions. Four treatments viz.; No wee...

This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland). We simulated the use of rice varieties with a higher temperature sum as adaptation option. We simulated rice yields for 4 RCP climate change scenarios and identifie...

Biological nitrogen fixation is the most important biochemical reaction for life on earth. Phosphorus and rhizobium inoculation increased N2-fixation by legumes. Legumes in rotation with cereals contribute to the total N pool in soil and improved cereals yield. In view of importance of grain legumes and the role they can play in maintaining soil productivity and succeeding cereal yield, rotatio...

Thirty advanced breeding lines of deep-water rice were evaluated during T. Aman season (rainfed ecosystem) with a view to finding out variability and genetic association for grain yield and its component characters. All the tested characters showed significant variation. The highest genetic variability was obtained in filled grains/panicle followed by plant height. Panicles/plant, filled grains...

to study the effect of sowing date and supplemental irrigation on grain yield and distribution and remobilization of phosphorus in canola (brassica napus), this experiment was carried out in 2 years (2005-07) in research station of gonbad. the study was carried out in two types of irrigation treatments (rainfed, supplemental). both experiments were carried out in randomized complete block desig...
