to evaluate the quantitative and qualitative of forage in intercropping of sorghum and chickling pea under limited irrigation systems, an experiment was conducted in research farm, college of agriculture, university of tehran, during 2009 and 2010. the treatments were arranged as split plots consisted of three levels of irrigation regimes including control (irrigation after 70mm evaporation fro...

Bioenergy sorghum is targeted for production in water-limited annual cropland therefore traits that improve plant water capture, water use efficiency, and resilience to water deficit are necessary to maximize productivity. A crop modeling framework, APSIM, was adapted to predict the growth and biomass yield of energy sorghum and to identify potentially useful traits for crop improvement. APSIM ...

a randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. water levels were (100%, 80%, and 60% replacement of plant water requirement) which served as main plots. subplot was a factorial arrangement of three different sweet corn varieties (merit, ob...

Elevated CO2 often increases grain yield in wheat by enhancing grain number per ear, which can result from an increase in the potential number of florets or a reduction in the death of developed florets. The hypotheses that elevated CO2 reduces floret death rather than increases floret development, and that grain size in a genotype with more grains per unit area is limited by the rate of grain ...

Maize silage has been used as a forage reserve strategy for critical periods or continuous use in animal feed. However, new genotypes and their potential must be identified. Thus, this study aimed to evaluate the of maize grain one off-season midwest region Brazil, under limited water frost, select them dual purpose (silage grain) using GT Biplot tool. The experiment was performed at Embrapa We...
