in order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, ardabil, iran, in 2007. experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

this research was conducted to evaluate the effect of different nitrogen and zinc combination on grain yield and its component in maize by path analysis. this experiment was carried out through split plot based on rcbd, varieties as main plot and fertilizers as sub plot, with three replication at badjgah (experimental farm of shiraz university). nitrogen fertilizer in (120,260 and 400 kg/ha) an...

due to extent of zinc (zn) deficiency in soils of iran and its deficiency in human diet, this study investigated the effect of zn sulfate foliar applications (non-foliar application, 0.5 g/l at stem elongation stage, 0.5 g/l at stem elongation and grain filling stages, 0.5 g/l at stem elongation and 2 g/l at grain filling stages) on yield and its components (farm sector) and influence of grain ...

Thirty advanced breeding lines of deep-water rice were evaluated during T. Aman season (rainfed ecosystem) with a view to finding out variability and genetic association for grain yield and its component characters. All the tested characters showed significant variation. The highest genetic variability was obtained in filled grains/panicle followed by plant height. Panicles/plant, filled grains...

The grain level in a silo is commercially important. In this work, a novel method is presented to detect the grain level in a silo. Existing methods are generally based on approximations, due to grain dust in the silo. The method proposed here eliminates the effect of grain dust and gives the accurate reading of the grain level. The method is based on the measurements of capacitances of paralle...

The embedded atom type otentials and static relaxation method combined with the steepest descent computational technfque have been used to simulate the grain boundary atomic structures, grain boundary energies, grain boundary cohesive energies, the distribution of electron density and stress field in the rain boundar re ion, the formation energies of vacancies and other related problems of [IOO...

A three-dimensional Monte-Carlo (Potts) model was modified to incorporate the effect of grain-boundary inclination on boundary mobility. For this purpose, a straightforward geometric construction was developed to determine the local orientation of the grain-boundary plane. The combined effects of grain-boundary plane and misorientation on the effective grain-boundary mobility were incorporated ...

sowing date and plant density are important factors in grain yield of cow pea. in order to study effect of sowing date and plant density on yield and yield components of cow pea, an experiment was conducted in research farm of ramin university of agricultural and natural resources in 2008. the experimental design was split plots in randomized complete design with four replications. the experime...
