individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...

in order to investigate genetic correlation and path analysis between grain yield and yield components, fifteen early maturing hybrids of grain corn (zea. mays) using a randomized complete block design with 4 replications were evaluated in khoramabad agricultural research center, iran. the data were collected and analyzed for ear emergence date, anthesis date, maturity date, plant height, ear h...

We extend the common theme of random Apollonian packing of circles to consider orientable grains with a noncircular shape. Systems of up to 10(6) grains are examined for a range of polygonal and elliptical shapes using both the random Apollonian packing model and the new rotational random Apollonian packing model which takes into account the extra rotational degree of freedom of noncircular gra...

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...
