This research was investigated to study the application of chemical and biofertilizers on growth, yield and fatty acids composition of safflower intercropped with faba bean based on a randomized complete block design with three replications at the Research Farm of University of Tabriz during two growing seasons of 2014-2015 and 2015-2016. Intercropping ratios of safflower and faba bean including 1:1, 2:1, and their sole cropping and four levels of fertilizers including no fertilizer, 100 percent chemical fertilizer, 30 percent and 60 percent chemical fertilizer + biofertilizer (Azoto barvar 1 and phosphate barvar 2) were evaluated. Results showed that the highest Chlorophyll content, plant height and number of branch per plant were devoted to safflower/faba bean intercropping (1:1) with application of 60 percent chemical plus biological fertilizers. Also, integrated use of chemical and biological fertilizers caused the increasing of seed yield, oil content (33.81 percent) and linoleic (76.97 percent) and linolenic (0.32 percent) fatty acids. The highest land equivalent ratio (1.41) was achieved in intercropped plants (1:1) with integrated use of 60 percent chemical and biological fertilizers. For both years, total actual yield loss for all intercrops was more than zero, which indicates the positive advantage of intercropping over the pure one. Overall, intercropping (safflower/faba bean) with integrated use of the chemical and biological fertilizers, can recommend as an appropriate manner for the production of safflower with a better quality and quantity.

In respect to drought crisis in the center of Iran, it needs valuable crops which adapt to such environments, a field experiment was conducted to investigate the effects of drought stress on different castor ecotypes at two places (Isfahan and Shahrekord) in 2013. Experiment was carried out in split plot arrangement in randomized complete block design (RCBD) with three replications that four drought stress levels (non-stress equals 30, 45, 60 and 75 percent moisture depletion soil) as a main plot and six castor ecotypes (’Isfahan ‘, ’Ardesrtan ‘, ’Arak ‘, ’Naeen ‘, ’Yazd ‘ and ’Ahvaz‘) as a subplot in two mentioned places. The results from both experiments were analyzed by combined analysis. The measured traits were including plant height, leaf number per plant, LAI, capsule number per plant, seed number per plant, 100 seeds weight, grain yield, harvest index, oil percent and oil yield. The results showed that the highest seed yield and oil yield were related to ’Isfahan‘ ecotype in Isfahan region under control with 1388 and 673 kg/ha, respectively.

In order to study the effect of drought stress in terminal growth period on agronomical and physiological characteristics of canola (Brassica napus L.) cultivars, a field experiment was conducted using split-plot layout based on randomized complete blocks design with four replications at experimental field of Seed and Plant Improvement Institute, Karaj in 2006. There were two factors, including irrigation at two levels (irrigation after 80 mm evaporation from class “A” pan as control and drought stress from flowering stage until physiological maturity) as main plots. In addition, twelve spring cultivars: (RGS003, Sarigol, Hyola401, Hyola 60, Hyola 330, Kimberly, 19-H, PR-401/16, PP-308/8, ORS 3150-3006, RG 4403, and RGAS 0324) were applied in sub plots. Results showed that RG 4403 had maximum grain yield (3228 Kg/ha) and harvest index (29.9%). In drought stress conditions, best cultivar in grain yield, 1000-seeds weight and oil yield was 19-H and with comparison of stress tolerance indices had better compatibility to water stress. Sarigol and Hyola330 had the lowest yield and yield components and ORS3150-3006 was the most sensitive to water stress.
