to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...
to determine the correlation between important traits with yield in barley through path analysis for selecting high yielding lines, three new lines of barley resistant to cold (c-81-13, c-81-11, c-81 -15), compared with valfajr (as control) were studied. this experiment was conducted in a randomized complete block design with three replications, during 2008 to 2010 in boyer ahmad city.a number ...
the present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. to this end the experiment was conducted in 2010-2011 in south west of iran as split plots based on randomized complete block design with three replications. main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
We present an experiment done on a bar(+) wheat line treated with 14 different concentrations of glufosinate ammonium-an effective component of nonselective herbicides-during seed germination in a closed experimental system. Yield components as number of spikes per plant, number of grains per spike, thousand kernel weight, and yield per plant were thoroughly analysed and statistically evaluated...
Collection and conservation of germplasm, particularly for landraces of important agronomically species and organizing their information, cause to continuity of their usefulness and reduce the risk of their genetic erosion. In this experiment, 10 Iranian wheat landraces along with the Chinese Spring cultivar, as control, were used to assess inter and intra populations variation by using ISSR mo...
Abstract Cyanobacteria like Arthrospira platensis and Nostoc muscorum are known to be beneficial for plant development. They can improve growth, yield, proximate content (protein carbohydrate), stimulate tolerance abiotic stresses herbicides. In the present study, impacts of brominal herbicide (Bh) alone or in combination with natural cyanobacterial synthetic tryptophan treatments were investig...
A field experiment was carried out during the winter season 2020-2021 in AL-Sufia area, east of Ramadi, to estimate effect spraying cytokinin on growth and yield barley (Hordeum vulgare L.). By using split plot plate arrangement by randomized complete block design (RCBD) with three replications, study included two factors, first factor, concentrations 0 (K1), 30 (K2) 60 (K3) mg L-1. taken spray...
a partial set of diallel crosses conducted among seven bread wheat genotypes contain (gasspard,m86-4,m86-6,dn-11,ws82-9 and m86-12) along with 21 hybrid, based on randomized complete block design(rcbd) with three replication were evaluated. the experiment was accomplished in a research field of agriculture and natural research center of tehran province in 2012-2013 in order to study genetic ana...
Plant growth regulators (PGRs) are used to prevent reduction in wheat grain yield under limited moisture conditions. The effect of 3 PGRs including cycocel, salicylic acid and brassinoestroeid on yield and yield components of four wheat cultivars (Chamran, Shiroudi, Pishtaz and Sirvan) under well watered and water stress (withheld irrigation after flowering) was examined. The experiment was ca...
