This research, was conducted in a population of 103 doubled-haploid (DH) lines, their parents and 5 Iranian local bread wheat cultivars, at three ys (2007-2009) in the field as triple rectangular lattice (10×11) designs. The results of AMMI analysis for grain yield per unit area showed: effects of year, genotype and their interaction effect were significant (P<0.01) indicating the significant...
Pepper is one of the nutrition demanding vegetable. In order to compare N fertilizer uptake and plant numbers per area unit, an experiment was conducted with replications. In which fertilizer was the main factor and included Ammonium nitrate in 7 levels (0, 80, 160, 240 kg /ha-1) and 40+40, 80+80, 120+120 kg/ha-1 (in 2 stages i.e. Half of these amounts appliedpre planting ...

in order to study the effect of plant density and sowing date on ear economic yield and sugar content in sweet corn (zea mays l. cv. saccarata), a field experiment was conducted at tarbiat modarres university (tehran west) in 2004. the experiment was carried out using split plots based on randomized complete block design of 4 replications. four levels of sowing date (may 22th, june 10th, july 1...
This study the effect of seed preparation (priming) with different concentrations of hydrogen peroxide on the anatomy of the flag leaf and spike two wheat genotypes( Cross Sabalan ( bread wheat) and Saji(durum wheat)) and its relationship with grain yield, under dry land farming system condition, Experimental design was factorial, arranged in randomized complete block. Results showed that the n...
Extended Abstract Introduction and Objective: The cow cockle has a great potential for producing medicinal products due to its triterpenoid saponins. This experiment was aimed to investigate different cow cockle ecotypes under drought stress conditions and select the tolerant ecotype(s) based on agronomic traits using selection indices under different irrigation regimes. Materials and Methods...
In order to study changes in morphophysiological traits of wheat cultivars released from 1940 to 2000 in Iran and to determine the association of these traits with grain yield, an RCBD experiment was conducted with 15 wheat cultivars released during past 60 years in Arsanjan (Fars province) in 2006 and 2007. Results indicated that grain yield increased significantly during these 60 years (r=0.9...
objective: wheat is the most important crop in iran. self sufficiency in wheat production is one of the economic and food safety policies in the country. in spite of the efforts which have been made in this area, the mean of wheat yield in iran is less than its world average. methods: in order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
In order to investigate the effects of solitary and combined application of chemical and biological fertilizers on the yield and yield components of quinoa plant, a factorial experiment was conducted based on randomized complete block design with three replications in Dastgerd (Borkhar), Isfahan, central Iran, during the 2017-2018 growing season. Experimental factors included four levels of Che...
An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...
