Abstract
The present study was conducted to evaluate the yield and agronomic traits of commercial soybean genotypes and introduce the genotypes that are compatible with higher yield potential for both spring and summer cultivation seasons. This study was carried out in a split plot experiment based on randomized complete blocks with three replications during two cropping years, 2008-2009 and 2009-2010, in the field of agricultural and natural resources research center of Moghan. The main plot was the cultivation date in two levels of summer and spring cultivation and the subplot was 14 cultivars of soybean including Sahar, Linford, Hobbit × Williams, Davis× Williams, 032, DPX, Ronack, JK, BP, 033, Clarck,Williams, Zan and L17. A combined analysis of the grain yield over two years revealed that the effect of cultivation date, genotype and their interaction was significant at 1% probability level. Comparison of the two cultivation dates demonstrated the yield rates of 3642.1 and 2530.3 kg/ha for spring and summer cultivation, respectively. Zan and Linford varieties with yield rates of 4276 and 4105 kg/ha respectively over the spring cultivation and the cultivar of BP and L17 with yield rates of 2974 and 2920 kg/ha respectively over the summer cultivation had the highest yield among all cultivars.

Abstract
To study the effects of drought stress and salicylic acid and Chitosan spraying on safflower, an experiment was conducted as a split plot design as base of a randomized complete block design with three replications. The drought stress had 4 levels ascontrol and irrigation after 25, 50 and 75% of soil available water as main plots and sprayin of salicylic acid (0.424 grams per liter), chitosan solution (5 g per liter) and both of them that were considered as sub-plots. drought stress reduced the number of heads per plant, head diameter, stem diameter, number of leaves, seed weight, seed weight and increased the percentage of hollowness of the seed. Application of chitosan and salicylic acid increased the distance of the first branch from the ground, head diameter, stem diameter, number of leaves, flowers, root length and weight and yield components as number of seeds per head, seed weight per head, seed weight and unfilled seed percentage. It seems salicylic acid and chitosan spray can be sugested to develop boost crop cultivation and increase safflower yield in the province of Sistan.
