Tillage methods are among the most successful factors in agriculture that have a significant impact on the quality and quantity of agronomic plants. To evaluate different tillage methods and urea fertilizer with nitrapyrin on total chlorophyll content, grain protein, yield, and yield components of two barley (Hordeum vulgare L.) cultivars, an experiment was conducted as split factorial in the r...

Water resources are limited. Thus, one of the ways to prevent the decline of maize yield under water shortage conditions is the use of growth regulators. In this study, the effects of proline (150 mg/L) and salicylic acid (0.5 mmol) on the  yield and water use efficiency of maize were investigated under three irrigation regimes, including complete irrigation (control), 75% of complete irrigatio...

     Determining the relationships between grain yield and some yield components of wheat is most important in permanent yield production.  Using path coefficient analysis in order to determine key traits affecting majorly yield, and also to study direct and indirect effects of yield and yield components, this research was performed during 2006-2009 ys using 94 doubled-haploid (DH) lines, their...

Genetic diversity of 13 new cereals, primary tritipyrum lines, five triticale lines and nine Iranian bread wheat varieties was studied under the randomized completely blocks design in terms of agronomic and morphological traits. The highley significant difference was observed between genotypes for all traits except in the filamental leaf length, main leaf length and main leaf width. The highest...

In order to evaluate the effect of water stress and nitrogen levels on yield and some agronomic traits of two forage sorghum cultivars, a field experiment was conducted at the Faculty of Agriculture, Shiraz University, during Spring and Summer 2011. The experiment carried out as split-split plot based on randomized complete block design, with 3 replications. Water stress levels of 100, 75 and 5...
