in order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in gorgan research station. this experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 oct., 12 and 28 nov. and 12 dec.) as main plo...

to study the effects of sowing dates, irrigation intervals and different cultivars on sugar beet root rot disease management and its quality and quantity yields, an experiment was conducted in a split- factorial based on randomized complete block design with four replications in the field of sugar factory jame. two irrigation intervals: eight days and 16 days were allocated in main plots, and d...

to investigate the effects of sowing date on yield and quality of six forage maize cultivars in rasht region, a field study was conducted in 2010. the experimental design was a randomized complete block using a factorial arrangement with three replications. treatments consisted of four levels of sowing date (22 may, 3, 15 and 25 june), and six maize cultivars (sc 260, dc 370, sc 500, sc 647, sc...

to evaluate the effects of seed priming with salicylic acid on quality and baking traits of wheat flour, cv. alvand, under different sowing dates, a factorial experiment was conducted on the basis of complete randomized block design. the factors were seed priming with salicylic acid (including untreated seeds or control treatment, 400, 800, 1200, 1600, 2000 and 2400 µm concentrations of salicyl...

background and objectives: sugar beet (beta vulgaris l.) is the major crop in khorasan province which is mainly grown in spring. however, autumn sowing has a lot of advantages including lower crop water requirement and higher water use efficiency. accordingly, this research was performed to compare the yield of storage organ in spring and autumn-sown sugar beet and determine the most appropriat...

in order to study the yield and growth indices of spring safflower as double cropping, an experiment was carried out in 2007 at the research farm of faculty of agriculture, yasouj university, iran. the experiment was a factorial based on randomized complete block design with three replications. factors included of combination of four sowing dates (may 16, june1, june 16 and july 2) and four cul...

augment of germination rate is important in seedling establishment and crop yield. a set of study in laboratory & field conditions at agronomy department of university of tehran was conducted during 2004-2005. in lab. experiment the effects of seed priming was evaluated on germination indices (germination percentage and rate) of chickpea genotypes in a factorial experiment of 4×3×2 arranged in ...
