In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

In order to study yield component and determinate the contribution of stem reserves to corn yield under effect of different densities and interference periods of sorghum, a factorial experiment based on randomized complete block design with three replications was conducted in 2002 on the Research Farm of the Faculty of Agriculture Tabriz University. Experimental factors were sorghum interferenc...

Performance of any breeding program is mainly due to the correlation among yield and relative importance of each component. This study was conducted to analysis the correlation among grain yield and some important traits in seventhin spring canola (Brassica napus L.) cultivars at the farm in safiabad, from 2014 to 2015. A randomized complete blocks design with four replications was used. The an...

To evaluate the effect of deficit irrigation and within row spacing on grain yield and yield components of grain sorghum promising lines, an experiment was conducted as split plot-factorial arrangement in randomized complete block design with three replications in 2015 and 2016 at the research field of Seed and Plant Improvement Institute, Karaj, Iran. Main plots consisted of three irrigation r...

Identification of easily measured physiological traits contributing to yield under specified environmental conditions would benefit genotypic selection for grain sorghum. A field experiment was conducted to determine broad-sense heritability and expected genetic advance, and to examine the relationships of grain yield with 11 physiological traits related to developmental periods, vegetative gro...
