to investigate the effect of water treatment and plant density on yield and yield components of two cotton cultivar, a two-year experiment (2006-2007) was carried out in esfahan agricultural research center. the use of a split plot factorial based on complete block with four replications for study. two irrigation levels 135 (i1) and 180 (i2) mm of cumulative pan evaporation class a, from flower...

in order to evaluate the effects of planting pattern on morphological, phonological, yield and yield components of sweet and super sweet corn (zea mays l.) varieties under saline conditions, a field experiment was conducted as split plots based on a randomized complete block design with four replications. planting pattern in 3 levels included one row in ridge, two row in ridge and furrow planti...

this research was done to study the effect of swing date, temperature, and sunshine hours on the yield and yield components of soybean in aliabad katool area (golestan provience), iran in 2012 year. in order to this purpose different soybean fields with different swing date had been remarked in vast area of soybean fields of katool aliabad area. entirely, in this study 30 soybean fields of kato...

Abstract Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited irrigation regime on yield, yield components and water use efficiency of sweet corn (Zea mays var. saccharata). Responses of three sweet corn varieties KSC403, Merit and Obsession to three di...

in order to study the effects of salicylic acid and selenium application on yield and yield components of rainfed wheat cultivars, a field experimental was carried out as factorial based on randomized complete block design with four replications in the research station of islamic azad university- arak branch, iran in 2010-2011 growing season. the treatments were salicylic acid and selenium. sal...

in order to study of yield, yield component, plant height, total dry matter and radiation use efficiency with 13 spring varieties of rapeseed ,an experiment was carried out in 2007 growing season at agriculture and natural resources research station of torogh,mashhad. these cultivars were from three rapeseed species belonged to brassica napus, brassica rapa and brassica juncea. experimental des...

Corn production management including nitrogen consumption will be different at different circumstances. In order to investigate the effect of different levels of nitrogen fertilizer on yield and yield components of seed corn hybrids in Khuzestan weather conditions, this research was carried out in the summer of 2013 in the lands of Safi Abad Agriculture and Natural Resources Research Center-Dez...

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...

Due to increasing water and growing demand for food a more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving condition...

uniparametric, non-parametric methods and ammi model (additive main effects and multiplicative interaction) were used to evaluate the yield stability of ten cotton cultivars at six regions of golestan and mazandaran provinces (baye kola, gharakheil, kalaleh, khan bebein, karkandeh, hashem abad) during two successive years ( 2005 & 2006). the experiment was conducted in randomized complete block...
