in order to study effect of foliar application of iron and zinc on yield and yield components of autumn rapeseed (brassica napus l.) under limited irrigation an experiment was conducted at research farm of agricultural faculty of urmia university in 2009. the experiment was designed in split plot based on randomized complete block design with 3 replications. treatments were drought (irrigation ...

To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and  oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

to investigate the effects of supplementary irrigation and application of different compost levels on morphological traits, yield and yield components of two chickpea cultivars under dry land conditions, a field experiment was conducted at the research field in khoramabad, iran in 2009-2010. the experiment was split split plot based on randomized complete block design with four levels of irriga...

Current study was carried out to assessment the effects of zeolite on seed yield, physiological and biochemical traits of sorghum in response to different irrigation regime according split plot arrangement based on complete randomized block design with three replications in Varamin region (Central of Iran). The main plots consisted of different irrigation regime at four levels [Normal irrigatio...

abstract in order to investigate the effects of different irrigation regimes on yield and yield components of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad. six irrigation regimes including i1= full irrigation, i2= irrigation at branching, i3= irrigation at flowering, i4= irrigation at pod formation, i5= irrigation at seed filling stage, and i6=...

A split plot factorial experiment in RCBD with 3 replications was performed in 2012-2013. Three sesame cultivars namely Biarjomand native, Dashtestan 2, and Darab 1 in the main plot were subjected to drought stress at different growth stages, i.e., control (full irrigation), withdrawing irrigation at 69 BBCH (end of flowering stage) and withdrawing irrigation at 79 BBCH (fully grown fruits). Tw...

BACKGROUND: Drought stress is one of the most critical factors in the reduction of yield among plant growth factors. Salicylic acid is a regulator that plays a vital role in the physiological processes of the plant. Gibberellin is one of the plant growth-regulating hormones that have different effects on the growth and development of many plants during growth stages. <str...

There is a need to optimize water-nitrogen (N) applications to increase seed cotton yield and water use efficiency (WUE) under a mulch drip irrigation system. This study evaluated the effects of four water regimes [moderate drip irrigation from the third-leaf to the boll-opening stage (W1), deficit drip irrigation from the third-leaf to the flowering stage and sufficient drip irrigation thereaf...
