to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...
in order to study the effect of supplementary irrigation and different plant densities on grain yield and yield components of chickpea cv hashem, an experiment was conducted as split plot arrangement in a randomized complete block design with three replications in sirvan, ilam during 2008-2009 cropping season. main plot included supplementary irrigation (check as non-irrigation, supplementary i...
A major source of photoassimilates deposited into the seeds is the closest photosynthetic source to the latter sinks. While the contribution made to grain yield by floral parts and the adjacent photosynthetic surfaces has been determined for a number of crop plants, such information lacks regarding safflower. Thus the present study was aimed at estimating the contribution of photosynthesis of s...
The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyzed the genetic control of this trait and ...
Planting density, through its impact on the level of available environmental factors may have significant impacts on grain yield in safflower (Carthamus tinctorius L.). In order to investigate the impacts of plant density on grain yield, yield components and growth characteristics of safflower, a randomized complete block design field experiment with four replicates was conducted in spring-summ...
to investigate the effect of wild mustard plant density and nitrogen fertilizer on morphological characters, yield and yield components of canola a split-plot experiment based on a randomized complete block design with 3 replications was carried out in bu-ali sina university of hamedan, in 2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kgn h-1) were assigned to main-plots and p...
this experiment was conducted in safi abad agricultural research center of dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 pla...
In order to evaluate relations between phonological trains , yield components and grain yield of 30 soybean lines with different maturity groups , an experiment conducted as a randomized complete block design with three replications at the agricultural research station of agriculture and natural resources research center, Gorgan, Golestan Province in 1388. 13 traits of vegetative and reproduct...
in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...
in order to study the effect of n fertilizer rates on morphological traits, yield and yield components of rice cultivars, a study was carried out in rice research institute of rasht, iran during 2009. it was a two-variable factorial experiment based on a randomized complete block design with three replications. the first factor was nitrogen fertilization at four rates of 0, 30, 60 and 90 kg n h...
