in order to study the effect of fertilizing treatments and limited irrigation regimes on yield and yield components of isabgol, a field experiment was conducted at experimental farm of college of agronomy and animal sciences, university of tehran. the experimental design was a split plot based on a randomized complete block design with three replications. in this research four irrigation regime...
A field experiment was conducted to evaluate the crop water stress index (CWSI), grain yield and canopy temperature of triticale under two irrigation regimes at Research Station of College of Agriculture and Natural Resources of Darab, Shiraz University, in 2013. A split plot design was used with three triticale cultivars (Sanabad, ET-83-3, and ET-84-5), as sub-plots and four levels of irrigati...
in order to study the interrelations of photosynthetic rate and surfaces and leaf proline content with yield and yield components of safflower under different irrigation regimes, a field experiment in a split plot arrangement under a ranomized complete block design with four replication was performed at lavark reasrch farm, isfahan university of technology, isfahan, iran in 2007. two irrigation...
Restricted water resources are a limiting factor for irrigation applications throughout the world. The effects of irrigation regimes (amount) on cotton lint yield are known, but there is little information on the effect of irrigation regimes on seed quality of cotton. In this study, the effects of deficit irrigation after the onset of flowering on lint yield and seed quality of cotton (Gossypiu...
Yield is a function of root distribution and activity. In flood conditions, root growth and efficiency are essential for crop productivity. The goal of this study was to investigate the effect of different irrigation regimes on the root development, yield and yield components of green pepper (green Hashemi cultivars). This study, which was based on a completely randomized design with three repl...
the experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in kabootatabad of esfahan farm. an experiment was conducted in split plot and was designed in randomized complete block with three replications. irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...
Various environmental stresses are one of the most important causes of many problems in agricultural production and drought stress is one of these tensions. Considering the role of nanoparticles in improving the yield and resistance of plants to environmental stresses, this experiment was conducted on Rosa damascena as a factorial experiment based on a completely randomized design with three re...
This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...
In order to study the effect of natural zeolite superabsorbent on yield and yield components of linseed under different moisture regimes, a split plot experiment was conducted in a randomized complete block design with 3 replications at Research Farm of Shahrekord University, Shahrekord, Iran in 2017. The main factor in four moisture regimes included irrigation after 50 (control), 80, 130 and 1...
the effect of drought stress on yield and components of three varieties of autumnal rapeseed in the south eastern region of isfahan, utilizing four irrigation regimes (i.e. no irrigation from flowering stage on, no irrigation from the podding stage on, no irrigation from grain filling stage on, and a normal irrigation regime after 80 mm evaporation from class a evaporation tube) were studied...
