this experiment was conducted to quantify leaf production and senescence in wheat. the experiment was carried out at research farm of the gorgan university of agricultural sciences and natural resources, gorgan, iran in 2005 using a randomized complete design considering sowing dates as environment. treatments were sowing date (14 december, 20 jan and 21 feb, 2005) and cultivars (aria, atrak, k...

in order to assess the impact of different sowing dates on yield and yield components of wheat genotypeswith different growth habits, a two years study (2007-2009) using a split plot in randomized completeblock design with three replications was conducted in kabootarabad agricultural research station ofisfahan. three sowing dates of 12 oct., 1 nov., and 21 nov. were main plots and 15 genotypes ...

in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...

sowing date is the most important factor in physiological and morphological characteristics with positive effects on plants. to evaluate the effect of sowing date and weed interference on yield and yield components of red beans cultivars a factorial split plot experiment in randomized complete block design with three replications was carried out in the research field of zanjan university. main ...

this research was done to study the effect of swing date, temperature, and sunshine hours on the yield and yield components of soybean in aliabad katool area (golestan provience), iran in 2012 year. in order to this purpose different soybean fields with different swing date had been remarked in vast area of soybean fields of katool aliabad area. entirely, in this study 30 soybean fields of kato...
