in order to study the characters affecting grain yield of lentil, a randomized complete block design with three replications conducted at dryland research station of northern khorasan (shirvan) in year 2002-2003. during the growth season and after harvesting, number of days to emergence, days to 50 percent flowering, days to maturity, number of primary and secondary branches, small and big diam...

Experiment was designed to establish a more defi nitive relationship of phenological and physiological traits with yield in wheat using twenty fi ve spring wheat genotypes. Because many of these traits are interrelated, correlation coeffi cient, path analysis and principal component analysis were used to expose these relationships more clearly. Experiment was conducted at the Wheat Research Cen...

Improving winter wheat grain yield and water use efficiency (WUE) with minimum irrigation is very important for ensuring agricultural and ecological sustainability in the Northern China Plain (NCP). A three-year field experiment was conducted to determine how single irrigation can improve grain yield and WUE by manipulating the "sink-source" relationships. To achieve this, no-irrigation after s...

in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...

The mungbean production area is increasing in Australia due to increasing demand for the grain in Asian countries. However, the mungbean crop is generally grown with wide row spacing, and therefore, it is prone to heavy weed infestation which has a significant impact on the mungbean grain yield. Experiments were conducted in 2015 and 2016 to determine the row-spacing impact on crop yield and we...

in order to study the effects of manganese sulfate in increasing seed yield of four safflower genotypes (carthamus tinctorius) under rainfed conditions, this experiment carried out in maragheh agricultural research station. the experiment was arranged with four mn fertilizer levels (0,10,20,30 kg ha-1) as soil application together with two foliar spray levels (1% and 2%) of 1.5 kg ha-1 manganes...

Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...

The rice (Oryza sativa) dwarf mutant d61 phenotype is caused by loss of function of a rice BRASSINOSTEROID INSENSITIVE1 ortholog, OsBRI1. We have identified nine d61 alleles, the weakest of which, d61-7, confers agronomically important traits such as semidwarf stature and erect leaves. Because erect-leaf habit is considered to increase light capture for photosynthesis, we compared the biomass a...
