to study the effects of different levels of water stress and nitrogen fertilizer on seed yield and yield components of two common bean genotypes (phaseolus vulgaris), an experiment in a split plot factorial based on crbd with four replications was conducted at the research farm of university of tehran (karaj-iran) in 2010. water stress treatments as the main factor included normal irrigation (6...

Peanut is grown mostly in rainfed areas where drought is a recurring problem. Peanut genotypes with high transpiration efficiency (TE) use less water and produced yield better under drought conditions. Specific leaf area and SPAD chlorophyll meter reading are used as surrogate traits for TE. N2 fixation (NF) is also used as a surrogate trait for yield under drought. The objective of this study ...

to evaluate of rice genotypes in various modified systems, an experiment was carried out as split plot in randomized complete blocks design with four replications at neka region, mazandaran province, iran in 2011-2012. cropping systems were chosen as main plots including conventional, improved and system of rice intensification (sri) and genotypes as sub plots including: sang tarom, hashemi tar...

to investigate the effect of plant density and supplemental irrigation on agronomic characteristics, chlorophyll content and light interception beneath the canopy of three chickpea genotypes under dryland conditions, an experiment was conducted at research station of lorestan agricultural research center located at chegini, khoramabad, during 2004-2005. the study was conducted using a split-spl...

in order to optimize use of water resources with selection of suitable wheat genotype(s) and irrigation schedule, in this experiment, the effect of elimination of irrigation at terminal growth and development stages of five wheat genotypes was investigated in two successive growing seasons (2002-03 and 2003-04) in the agricultural research station of torogh mashhad. split plot experiments were ...

in order to evaluation the effect of different crop rotation, fertilizer and protection managements on weed seed bank properties an experiment was conducted in close house experimental glass house on the soil of 5th year of organic rotation that is conducting in university of newcastle’s nafferton experimental farm. rotation was started with grass/clover for first two years and continued with w...
