to evaluate the effect of various levels of nitrogen fertilizer on nitrogen use efficiency and grain yield of canola cultivars, a split plot experiment based on randomized complete block design was conducted in 2007. factors were: nitrogen fertilizer at four levels (zero, 50, 100 and 150 kg/ha) in the main plots and canola cultivars at three levels (‘clover’, ‘opera’ and ‘okape’) in the sub plo...

to study the effects of different amounts of sulphur and boron fertilizers on grain yield and grain quality of bread wheat cultivar pishtaz, an experiment was conduncted in karaj during two cropping seasons 2001-2003. three levels of sulphur (s0= 0, s1=250 and s2= 500 kgha-1) and three levels of boron (b0= 0, b1= 20 and b2= 40 kgha-1) were different treatments of the experiment arranged in rcbd...

in this study, we aimed to determine the effects of halo-priming on yield and yield components of four wheat cultivars in a saline soil. a field study was conducted in factorial based on randomized complete block design (rcbd). soil ph was 8/1 and electrical conductivity was 9 ds/m. wheat cultivars (falat, ghods, chamran and shoori4) were primed with cacl2 solutions (control, 0, 50 and 100 mm)....

The objective of this study was to determine the effects of water regime/soil condition (continuous flooding, saturated, and aerobic), cultivar ('Cocodrie' and 'Rondo'), and soil texture (clay and sandy loam) on rice grain yield, yield components and water productivity using a greenhouse trial. Rice grain yield was significantly affected by soil texture and the interaction between water regime ...

in other to evaluate grain yield, rate and effective grain filling period of four barley (hordeum vulgaris l.) cultivars in different planting dates, a factorial experiment based on a randomized complete block design was conducted in the islamic azad university of ardabil research station in 2009. the treatments applied were: three levels of different planting dates (september, 23; october, 16 ...

this experiment was conducted to evaluate the effect of nursery establishment under plastic cover on yield of some rice cultivars at lordegan region in 2007. experimental design was a split plot with a randomized complete block with three replications. four rice cultivars (hashemi, hasani, saleh and native) were seeded at three seedling date (14 april, 5 may and 15 may). two first planting date...

in order to evaluate plant density and cultivar effects on rate and process of grain filling, yield and yield components of three dry bean cultivars a factorial experiment (using r.c.b. design) was conducted in 1386 at agricultural and natural research center of east azarbaijan (tabriz). three cultivars (khomeyn, g-14088 and 11816) were planted at four densities (14, 20, 30 and 60 plants/m2) in...
