Effect of plant density and planting date on yield and yield components of faba bean
Message:
Abstract:
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.
