lead to continuing effects for increasing extensive of yield by means of advanced agronomic operations and selection of high yielding resistant genotypes. there fore, due to evaluation and determination of best effective traits in improvement of yield and grain quality of local populations of winter wheat, an experiment was carried out in uremia agricultural research station, on 30 local popula...

Spike-related traits such as spike length (Sl), fertile spikelet number (Fsn), sterile spikelet number (Ssn), grain number per spike (Gns), and thousand-kernel weight (Tkw) are important factors influencing wheat yield. However, reliably stable markers that can be used for molecular breeding in different environments have not yet been identified. In this study, a double haploid (DH) population ...

a field experiment was conducted to study the physical properties of maize grain in response to different urea fertilization methods (urea foliar spraying and soil application), three harvest times (grain moisture content of 20, 30 and 40 pecent) in four maize hybrids (three foreign hybrids e.g. ns640, jeta600 , konsur580 and one common hybrid, sc704 as control) at khorram abad agricultural res...

DCPTA (2-diethylaminoethyl-3, 4-dichlorophenylether) and CCC (2-chloroethyltrimethyl- ammonium chloride) have a great effect on maize growth, but applying DCPTA individually can promote the increase of plant height, resulting in the rise of lodging percent. Plant height and lodging percent decrease in CCC-treated plants, but the accumulation of biomass reduce, resulting in yield decrease. Based...

This study was conducted at Setif Agricultural Experimental Station in 2017−2018 crop season, the experimental material used this consisted of 5 cultivars (Triticum durum Desf.) based on their difference between early and late cultivation. The genotypes tested were sowing a random block design with three replications, each plot 2 rows 2.5 m long spaced 20 cm. aim is to assess impact choice date...

Traditional rice landraces cannot be processed using standard machinery or unit operations. rice, on the other hand, is becoming more popular as its purported health benefits spread. Cracked grains, broken and subpar milled kernels result from non-standard equipment landraces. So, studying physical characteristics of paddy crucial for modifying milling to lessen post-harvest losses. To preserve...

in order to study of drought tolerance in bread wheat genotypes, this study was conducted in maragheh dryland agricultural research station. the study included two experiments and the statistical design of each experiment was a rcbd with four replications, and 20 bread wheat genotypes that were compared under drought stress (rainfed) and supplementary irrigation. analysis of simple variance sup...
