The present experiment was carried out to study the effect of planting date on yield and yield componts of some faba bean genotypes in a split plot based on Complete Randomized Block Design with three replicates in Guilan province during 2014-15 growing season. The main factor was four planting dates (20 November, 19 December, 5 January and 1 March) and the split factor was six faba bean genotypes (Guilan landrace, Borojerd landrace, France, Barrakat, FILIP3 and FILIP5). The effect of planting date was significant on all of the studied traits. The effect of genotype was also significant on all traits exept of days to maturity and relative water content. Interactions of two factors were significant on seed yield, number of days to emergence, hundred seed weight, number of seeds per pod and number of pods per plant. The highest ripening time of seeds (175.22 days) was observed in the first planting date and this time in the last planting date was reduced by 42%. Due to the significant interaction of genotype by sowing date, the simple effect of genotype was investigated at each level of sowing date and it was shown that in all four sowing dates, Gilan landrace had the highest grain yield with 3208.04, 1858, 110.8, 605.2 kg ha-1, respectively. Delay in planting incrased the seed nitrogen content by 22%. According to the results of present study and due to climatic ondition, early November is considered as an appropriate time for planting faba beans in the studied area.

To evaluate the effect of planting date and plant density on yield and other agronomic characters of faba bean, a split plot experiment were carried out based on randomized complete block design with three replications at Guilan province, during 2012-2013 growing seasons. Four planting dates (17 November, 12 December, 6 and 31 January) were arranged in main plot and three plant densities (8, 12 and 16 plant m-1) ordered in split plot. The measured traits including plant height, number of stems per plant, number of pods per plant, seed yield, harvest index and seed length. Analysis of variance indicated that the interaction effects of two factors were significant on plant height and number of pods per plant. Effect of planting date were significant on plant height, number of stems per plant, number of pods per plant, seed yield and seed length. Plant density had significant effect on all of the studied traits except of number of stems per plant and seed length. Early planting in November resulted in a substantial yield (4707.6 kg ha-1) increase to more than triple in comparison to yield obtained when planting done in January (1723.4 kg ha-1). Early planting resulted in more pods and stems and taller plants. The results indicated also a plant density up to 16 plants m-1 resulted in the greatest yield. It can be concluded that according to conditions of present study, maximum yield and yield components of faba bean will obtained in planting up to November at 16 plants m-1.

Beans as an important source of food are increasingly under attention nowadays. Genotypes as well as yield components can be affected by agricultural managements. This experiment was conducted as split plot based on randomized complete design with three replication in Challus city- Mazandaran Province. Main factor was distance between rows(25¡45¡65 Cm) and sub factor was distance of plants on rows(10¡15¡20 Cm). Results of distance between rows¡ distance of plants on rows and interactions showed significant differences for most of the measured traits. The best and highest yield obtained from 45 Cm distance between rows and 15 Cm distance between plants on the rows.
