This study was conducted to investigate the effects of thirteen fertilizer treatments (as main factor) on agronomic traits of two local cultivars (as sub factors) of sesame (Sesamum indicum L.), "Mobarakeh" and "Ardestan" in Isfahan by using a randomized complete block design with three replications. The results showed that applying fertilizer treatments of N, P, K, Fe, Zn and Mn had no signifi...

In order to achieve the most appropriate quantity and plant density of corn which could best use sunbeam and soil nutriets equally and could have the highest yield seed, an experiment in factorial way according to the base design of complete randomized blocks in three replications was performed in the summer of agricultural year of 2006 in the region of kuhdasht. Density factor was in four le...

Soybean is the promising oilseed in the face of protein and oil shortage. In this study 16 advanced soybean genotypes, in terms of seed yield and yield components were evaluated using multivariate statistical methods. This experiment was carried out in the form of randomized complete block design (RCBD) in the research farm of Ardabil Agricultural and Natural Resources Research Center (Moghan...

This experiment was conducted at the Agricultural Research Farm of Isfahan University of Technology in 2006 to evaluate the effects of row spacing and plant distance on the row on yield and yield components of sunflower, Hisun-36 hybrid. A split plot layout was used with a randomized complete blocks design and three replications. Row spacing (60 and 75 cm) was the main plot and plant distance o...

Safflower (Carthamus tinctorius L.) is cultivated in a wide range of geographical conditions in the world from Africa to Europe, India and China. Previous studies have shown that diversity in indigenous Iranian germplasm is limited for some traits therefore germplasm collections from other origins need to be considered. An experiment was conducted to evaluate agronomic and morphological traits ...

In order to evaluate effect of planting date and plant density on grain yield, yield components and some quality and morphological traits of chickpea (Cicer arietinum L.), an experiment was conducted at the research center of agricultural and natural resources of west Azerbaijan in Urmia rain-fed research farm during 2005-2006 growing season in a split plot arrangement, based on a completely ra...

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...
