Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...

Ratooning means regrowing of rice plant after harvesting of first product which is specific physiologic characteristic of rice plant. It is an effective method for increasing of efficiency of production along with less investment and also lack of necessity for increasing of the field of rice plant. Ratooning more over, affects on the optimal usage of agricultural field. In order to achieve this...

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...

in order to determine the appropriate plant density of spotted bean in yasouj, a field experiment was conducted in 2008 as a factorial in a randomized complete block design with three replications. three spotted bean cultivars (keshavarzi, talash and oshtori) were sown at five plant densities (10, 20, 30, 40 and 50 plant.m-2). results showed that effect of plant density, cultivar and interactio...

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...
