Abstract

A study was conducted at the College of Agriculture, Kirkuk University, Iraq to investigate the effect of planting distance on yield of faba beans (Vicia faba L.) under drip irrigation. The yield of three different varieties of beans (Spanish, Turkish and Local) at three different planting distances, including 20, 25 and 30 cm was studied. The result indicates that both the interactions between plant distance and different varieties of beans and that of the distance between plants were not significant at 95% level of significance. However there were significant differences (P<0.01) for the varieties of bean based on percentage of growth, plant height, branches plant^-1, pod length and number of seed pod^-1, with average values of 94.86%, 35.85 cm, 87.50 cm, and 10.39 cm, respectively. Also a significant difference (P<0.05) was found in the number of nodes plant^-1. Differences on the number of branches plant^-1 and weight of pods were not significant.

Key words: Drip irrigation, varieties, bean, pod, plant distance.
