Chickpea (Cicer arietinum L.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. In addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. In order to screen drought tolerant genotype in Chickpea, twenty genotypes were tested under rainfed and irrigated...

Under dryland systems of the Mediterranean basin, water management is widely recognised critical for improving grain yield. It has been proposed that nitrogen (N) fertilisation may be a tool to increase yield by increasing use efficiency. We tested in multilocation-multiyear study four different areas Basin if durum wheat and barley respond positively N under rainfed cultivation. The involved 1...

seed and oil yields, their components, and the relationships among trait performance were determined in 25genotypes of winter type oilseed rape (brassica napus l.). the experiment was carried out at the agricultural and natural resources research center of east azerbaijan, iran, in two consecutive growing seasons 2009-10 and 2010- 11. significant differences were observed in plant height, numbe...

In Iran, more than 90% of raw materials including oils and oil seeds are provided through import. Camelina sativa L. as an oilseed crop, belongs to Brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. This Experiment was conducted at research station of Campus of Agriculture and Natural ...

Although safflower is known to be a cool-season crop, it is usually planted as a summer crop in Isfahan. Thus, an experiment was conducted in 2000 at the Agricultural Research Station, Isfahan University of Technology, to study the effects of date of planting on growth, yield components, and seed yield of safflower. Five planting dates (March 12, April 12, May 10, June 8, and July 12) and four ...
