The main objective of this quantitative-qualitative research was to analyzing the mental preferences of paddy farmers towards second cultivation in Rasht County. The statistical population of the study consisted of 30 progressive farmers in Rasht County who were selected by purposive sampling technique. The collected data were analyzed by SPSS22 and Expert Choice11 softwares. The reliability and Validity of the questionnaire was approved by calculating the Cronbach's alpha and construct validity.The Findings showed that "lack of government support for the production and sale of these products, lack of successful model farms in cultivating alternative crops under government management" and "lack of an appropriate market for these products» with a ratio of 93, 90 and 73%, were the most important barriers to farmers' willingness to second cultivation, respectively. Also, the most important factors determining the type of cultivation were revenue generation, production costs and market for products, respectively. The results showed that, ratoon and local beans were in the highest ranks in the farmers' mental preferences in growing crops based on revenue generation, sales and production cost criteria, but in terms of water scarcity and employment criteria, local beans and forage were in the highest ranks, respectively. Overall, the results showed that, ratoon with a weight value above 0.453 was in the first priority in second cropping pattern and local beans and forage (with 0.353 and 0.087 weights) were in the next priorities, respectively. Designing an optimal cropping pattern, guaranteed purchase, establishing model farms and development of conversion industries are suggested.

To evaluate and determine suitable soybean lines for second cropping in moderate cold regions of Kermanshah, an experiment was conducted using nine soybean genotypes in a split plot based on an RCBD with three replications for two cropping seasons (2012-2013). In this study two planting dates of May 22 and July11 were as the main plot and soybean genotype were as sub plot. The results of combined analysis of variance revealed that planting date effect was significant for traits such as days to flowering and physiological maturity, plant height and pods per plant and grain yield. In addition, the results indicated that there were significant differences among genotypes for all traits under study with the exception of pods per plant and plant height. Planting date×genotype effect was significant only for seed oil and protein content. Three Genotypes viz. Linford, L17 and Williams had the high seed yield at planting dates with 3249, 3255 and 3186 kgha-1 for the first planting date and 2980, 2817 and 2695 kgha-1 for the second planting date, respectively. Based on the obtained results, genotypes such as Boutny, M7, M9 and LH-2500 with short growth duration and rather acceptable seed yield could be planted as a second cropping in temperate cold regions of Kermanshah.

In this study، development strategy of autumn crops in Guilan province is surveyed. Therefore، it is trying to use various economic and social indicators resulting from a field of more than 350 questionnaires that were collected from cultivated crops II units in Guilan province from 2008 to 2009 crop year، to introduce appropriate crops farmers and planners to develop this culture. In order to make decisions based on all the indicators، numerical taxonomy method was used. Results of numerical taxonomy approach showed that among the 6 crops studied according to the 10 indicators considered for the decision، the vegetables were determined after the order of glandular leaf vegetables، string beans ratvn and activities to develop improved crop cultivation in the second pattern of Guilan.
