plant photosynthetate partitioning is important in seed yield formation. in this research, in order to study grain filling procedure of chickpea in the presense of drought stress and nitrogen (n) fertilizer on remobilization rate, final grain weight and grain yield were measured. experiment was performed in an split-factorial using randomized complete block design with three replications. droug...

to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

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...

mprovement of N2 fixation might be an effective strategy in peanut breeding for high yield under drought stress conditions. However, under water limited conditions peanut varieties having high water-use efficiency (WUE) are favorable. A pot experiment was conducted under greenhouse conditions at Khon Kaen University, Thailand during December 2002 to May 2003, and repeated during June 2003 t...

Winter wheat production is threatened by drought stress under rainfed conditions; thus, screening high- and stable-yielding varieties to ensure the sustainable development of food security in Huang-Huai-Hai Plain (HHHP) vital. In this research, four-year field experiments with twelve winter were conducted during wheat-growing seasons between 2016 2020 order to: (1) screen conditions, (2) invest...

drought, specially in reproductive stage is one of the major constraints, limiting the productivity of crops, including chickpea (cicer arietinum l.). to study the effects of drought during pod set and seed filling stages (terminal drought) on phenology, growth and seed yield of 5 kabuli chickpea genotypes of: arman, jam, hasham, flip93-93 (azad) and ilc482, an experiment was conducted during t...

Drought stress is the principal cause of production losses in maize (Zea mays L.), especially a rainfed ecosystem. Reducing yield penalty under conditions demands development hybrids with improved tolerance to drought stress. The extent genetic variability and association among traits over irrigated water of  72 were studied. analysis variation reveaeds that significant was observed condit...

abstract cumin (cuminum cyminum) is one of the most important medicinal plants in iranian dry region. in order to study the effects of irrigation times and salinity stress on yield and yield components of cumin, an experiment was conducted at the research farm ferdowsi university of mashhad in 2009. factors including irrigation times (1: one time irrigation, 2: two times irrigation 3: three tim...
