objective: in order to study genetic variation and effect of drought stress on grain yield and some morphological traits in chickpea, an experiment was conducted on 64 genotypes during 2013-2014 cropping season at deputy of kermanshah sararood dry land agricultural research institute, located on the western part of iran. methods: the experimental design was a randomized lattice design with tow ...

drought stress due to water deficit and terminal temperatures is a serious problem in agriculture, and it is one of the most important factors contributing to crop yield loss. to evaluate drought tolerance of barley, 12 advanced barley genotypes were studied in two rainfed and irrigated conditions (in a subtropical region, gachsaran) in 2006-2007 in a rcb design with three replications. results...

Adsorption equilibrium and kinetics on lignocellulosic base adsorbents from oil palm bagasse (OPB) yam peels (YP) were studied for the removal of hexavalent chromium present in aqueous solution, a batch system, evaluating effect temperature, adsorbent dose particle size process. Isotherms fitted to Langmuir, Freundlich Dubinin–Radushkevich isothermal models. Kinetic data adjusted pseudo-first-o...

A large database of individual farmer field data (n = 4,107) for rice production in the Northwestern Indo-Gangetic Plains India was used to decompose yield gaps and investigate scope reduce nitrogen (N) inputs without compromising yields. Stochastic frontier analysis disentangle efficiency resource gaps, whereas on potential region were retrieved from Global Yield Gap Atlas estimate technology ...

The single-component adsorption of chromium (VI) and nickel (II) on oil palm bagasse (OPB) yam peels (YP) in a packed bed column was explored improved using central 22-star T composite design. temperature, height, particle size were evaluated, the optimized response variable removal efficiency. remaining concentration heavy metals solution determined by Ultraviolet–Visible Atomic Absorption Spe...

A pot culture experiment was conducted on Karaikal soil series (Vertic Ustropept) to study the response of rice genotypes boron addition and screening efficient using stress indices. Ten were tested at two (0, 2 mg kg-1) level boron. The result revealed that highest grain yield (88.40 g pot-1) straw (114.7 pot-1), maximum uptake (2192.3 µg (3291.9 recorded with application 2.0 kg-1. Amongst gen...

the first step in identification of genes which control traits in stress and no stress conditions is localization of chromosomal related to traits. in order to locate the genes controlling drought resistance and screening quantitative indices of drought resistance in wheat, substitution line series of hope into the genetic background of chinese spring (cs) were tested in a randomized complete b...

Sedentary aging results in a diminished rapid cutaneous vasodilator response to local heating. We investigated whether this diminished response was due to altered contributions of noradrenergic sympathetic nerves by assessing 1) the age-related decline and 2) the effect of aerobic fitness. Using laser-Doppler flowmetry, we measured skin blood flow (SkBF) in young (24 ± 1 yr) and older (64 ± 1 y...
