in order to study the effects of different irrigation regimes and nitrogen fertilizer levels on yield and yield components of chickpea (ilc482), a field experiment involving chickpea genotype ilc482 was conducted as factorial arrangement based on a randomized complete block design with four replications in the agricultural research station, ferdowsi university of mashhad during growing season o...
In order to investigate the effects of sowing date (SD) and single irrigation (SI) amounts on yield and yield components of rainfed wheat varieties, a field experiment was conducted as split-split plots arranged in a randomized complete blocks design with three replications during 2002-2004 at main station of Dryland Agricultural Research Institute in Maragheh, Iran. Treatments included three s...
In order to study the effects of foliar application of phosphorus (P) and water deficit on yield and yield components of winter wheat (Triticum aestivum L., cv. Alvand), a split-plot experiment, with completely randomized blocks design and three replications, was carried out at the Research Farm of Boyer Ahmad Agricultural and Natural Resources Research Station, 13 km west of Yasouj, in 2008-20...
drought is considered as the most important constraint to world’s crop production. furthermore arid and semiarid climate accounts for nearly most of terrestrial areas of iran. therefore in order to study the effect of irrigation regimes on growth, physiological attributes and grain yield as well as components of such a crop plant as safflower a 4-replicate split plot rcbd field study was perfor...
The present study was conducted in order to investigate the effect of salicylic acid on growth, yield and macro-elements absorption of fennel in split-plot as base on randomized complete block design (RCBD) with three replications in Tehran, Iran. Irrigation regime as main plot was undergone in 5 levels that included: I1: full irrigation, I2: cut off irrigation at stem elo...
Glasswort(Salicornia europaea L.) as an important halophyte plant is capable to accumulate NaCl in aboveground part (fully edible) in considerable quantity. To evaluate the effect of irrigation levels and nitrogen fertilizer on the yield of seed and oil, and also harvest index of Glasswort, a split plot experiment was conducted based on randomized complete block design with three replications a...
Poor irrigation water management is one of the major factors limiting crop production inEthiopia. This study was, therefore, conducted at three different locations in the southeasternEthiopia for 2 consecutive years to investigate the effects of different irrigation depths andintervals with furrow irrigation system on tuber yield, biomass yield and water use efficiency ofpotato. The treatments ...
This study was conducted to assess the effects of irrigation and plant growth promoting bactera on seed yield and qualitative characteristics of Black cumin (Nigella sativa L.) at the Experimental Station of the Research Institute of Forest and Rangeland, Damavan region, Iran. A split-plot experimental design, based on Randomized Complete Block Design (RCBD) with three replications, was used. I...
Alternate wettting and drying (AWD) systems save water compared with continuoussubmergence (CS) irrigation. However, the reported effect on yield varies widely and detailedcharacterizations of the hydrological conditions of AWD experiments are often lacking so thatgeneralizations are difficult to make. We compared the effects of AWD and CS on crop andwater productivity in rice in the field expe...
To evaluate and select the promising lines of dual purpose grain-forage sorghum under drought stress conditions, a field experiment assplit plot arrangements in randomized complete block design with three replications was carried out atresearch field station of Seed and Plant Improvement Research Institute, Karaj, Iran, in 2014 and 2015 growing seasons. Irrigation levels (60 mm, 120 mm and 180 ...
