The objective of this study was to evaluate some morphological characteristics associated with grain yield potential on 20 bread wheat cultivars under two irrigation and drought stress conditions. The experiments were conducted at Research Farm of Agriculture College, University of Tehran, Karaj during 2001-2003. Twenty bread wheat cultivars were planted as subplots within each irrigation main ...

SALTMED model has been developed to predict yield, soil salinity and watercontent under saline conditions. A two year field experiment was carried out during2012-13 to calibrate and validate the model for sorghum. Plants were irrigated withsalinity levels of 2, 6, 10 and 14 dS m-1. Results showed that there were significantdifferences between the observed and simulated sorghum dry matter (SDM) ...

  In this study, factor analysis was conducted to determine the factors which contributed to the variation of quantitative traits and path analysis was performed to find the direct and indirect effects of yield components on grain yield in bread wheat. A doubled haploid population of 157 lines of wheat (Triticum aestivum L.) was evaluated for agronomic and morphological traits, using a randomiz...

This experiment was conducted to determine the effects of time and rate of nitrogen fertilizer (urea) application on yield and yield components and quality of sunflower (Helianthus annuus L. )cv.Euroflor. A field experiment was carried out at College of Agriculture, Shiraz University during Summer 2009. The experimental design was a factorial based on a randomized complete block design with 3 ...

In order to study the effect of terminal drought stress on yield and yield components and some physiological traits of wheat genotypes, a field experiment was conducted at the Research Farm of Agricultural College of Shiraz University during 2010-11 growing season in a split plot arrangement based on randomized complete block design with three replications. Main plots were assigned to irrigatio...
