understanding the variation of kernel number per unit area (kno) is an important factor in respect yield and in identifying opportunities to increase potential yield. some crop models are for dependence on kernel number prediction to yield simulation. in order to quantify the relationship between kernel number per unit area and influencing parameters (environment and non-environment-based facto...

introduction determining the proper time for planting under different climate depends on the factors such as rainfall, temperature and length of day which are the most important aspects of crop production. its importance is because of the severity of these effects on different genotypes to achieve potential production. because different genotypes respond differently to planting delays. sowing d...

A study was conducted to check the effect of different sowing dates and row spacing on the growth, seed yield and quality of offseason pea (Pisum sativum L. cv. Climax). Significant differences were recorded among sowing dates for days to germination while nonsignificant results were found for row spacing and interaction (A × B). Maximum days to germination were recorded in D1 (20 th April) and...

to study the effect of seed sowing rate, different levels of nitrogen and different sowing dates on canola cultivar hyola401, a field experiment was conducted during 2005-2006 at safiabad agricultural research center. the design was a split split plot in a completely randomized block basis of 3 replications. main plots consisted of 3 levels of sowing dates (6, 26 nov and 16 dec), sub plots of 3...

Combining ability, gene action and heterosis was studied for no. of days to 50% tasseling, no. of days to 50% silking, flag leaf area, plant height, no. of rows/ear, no. of grains/row, 300-grain weight and grain yield/plant in a Factorial Mating in Randomized Completely Randomized Design conducted separately in spring and autumn sowing dates, 2013 through hybridization between three parents of ...

in order to evaluate the effect of different levels of sowing dates and plant density on grain yield and its components in chickpea var. arman, a field study was conducted at ekbatan research field station of agricultural and natural resources research center of hamedan province under rainfed condition during 2009-2010 cropping season. treatments were arranged as split plot on the basis of rand...

Cumin (Cuminum cyminum L.) is one of the most important cultivable medicinal plants in Iran and today, it is the second most popular spice in the world after black pepper. It is essential to know the relationships between yield and its components in cumin breeding programs. Therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine th...
