Drought stress (DS) at different growth stages of spring wheat (Triticum aestivum L.) may affect its grain yield and end-use quality differently. The impact drought on has been widely studied, but the not thoroughly investigated. A 2-year field experiment was conducted to evaluate effects DS in classes (soft white ‘Alturas,’ hard red ‘Coho,’ ‘Dayn’). treatments included (from tillering stem elo...
Development of cultivars better adapted to drought stress in the arid and semi arid climatic conditions is considered as a major breeding objective. Grain quality is a trait with physico-chemical complexity depending primarily on genotype, is strongly affected by environmental factors and their interactions. Effect of terminal drought stress on quality traits of 18 triticale lines, comprising o...
Drought and low nitrogen are major stresses for maize (Zea mays L.), populations from the Sahara Desert potential sources of stress tolerance. The objectives were to assess tolerance varietal heterosis effects Algerian under no-nitrogen fertilization water stress. A diallel among six population was evaluated drought (300 mm irrigation) vs. control (600 mm) 120 kh ha?1 N fertilization. Genotypes...
To investigate the effect of the timing of nitrogen fertilizer application on grain yield and quality of bread wheat cultivars under terminal drought stress conditions, two field experiments were conducted at Agricultural Research Station of Miandoab in West Azerbaijan, Iran, in 2013-2014 and 2014-2015 cropping seasons. Experimental treatments were arranged as split plot factorial in randomiz...
in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...
Selection of drought tolerant wheat genotypes for Arid and Semi-arid lands (ASALS) of Kenya, which consist of 83% of total land area, can provide alternative agricultural land for expansion. To reduce cost of dryland research, simulated drought under a rain shelter offers a good alternative for screening because marginal areas are vast and widespread. Four moisture regimes which simulated termi...
In order to determine suitable drought tolerance indices and to identify drought tolerant wheat genotypes, an experiment was conducted at the experimental field of Ardabil Agricultural Research Station in 2010-11 cropping season. Thirty wheat genotypes were evaluated in a randomized complete block design with three replications under stress as well as non-stress conditions. Drought tolerance in...
this study was conducted to evaluate traits that have an effect on yield, and genetic variation for these traits, including dry matter accumulation, remobilization, and traits associated with them, in 10 grain sorghum genotypes obtained from the national plant gene bank of iran under moisture stress conditions. field trials were carried out in the 2008 cropping season using split-plot arrangeme...
the experiment was aimed at investigating the effects of defoliation (i. e. amanipulation of source size) at different times and with different intensities on yield, grain protein content and remobilization of dry matter from shoot to grain under various levels of soil moisture and nitrogen in winter wheat. two separate field experiments were conducted simultaneously under water stress vs irrig...
