in order to investigate of different salinity stress and plant densities effects on quantitative and qualitative forage and grain yields of kochia a randomized complete block design in factorial arrangement with three replications was used. a field study was conducted in 2011 cropping season in agriculture experiment satiation, college of agriculture, islamic azad university, arak branch treatm...

A simulation model was developed to predict corn crop residue yield and quality and intake and performance of growing cattle grazing cornstalks. The model is wholly deterministic and integrates the effects of weather, residue supply and animal components. Low temperatures increase animal energy requirements, whereas snow cover decreases residue available. Residual grain and leaf are calculated ...

in order to study the effect of supplementary irrigation and different plant densities on grain yield and yield components of chickpea cv hashem, an experiment was conducted as split plot arrangement in a randomized complete block design with three replications in sirvan, ilam during 2008-2009 cropping season. main plot included supplementary irrigation (check as non-irrigation, supplementary i...

in order to study the effects of nitrogen and drought stress on yield, yield components and seed quality of corn (hybrid single cross 704) a field experiment was conducted at agricultural research station in islamabad gharb in 2009. experiment design was split plots based on randomized complete block design with three replications. main plots included full irrigation requirement, 80 percent and...

dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...
