Study of dry and wet planting effects on grain yield of genotypes spotted bean (Phaseolus vulgaris) genotypes

In order to study wet and dry planting effects on grain yield of spotted bean cultivars, an experiment was conducted on four bean cultivars in Khomein for two years (1995 and 1996). The experimental design was split block in randomized complete block design with four replications. Four spotted bean cultivars (Talash, Local Khomein, G-14088, COS-16) were assigned as factor A to vertical plots, and two sowing methods (wet planting, and dry planting) as factor B in horizontal plots. In this study planting arrangement was 20 cm × 14 cm. The results revealed that there were significant differences among bean cultivars in plant height, number of pods/plant and seeds/plant, 100-seed weight and grain yield. Local Khomein cultivar had the highest plant height. Number of pods/plant and yield in COS-16 were higher than the other cultivars. Study of sowing methods, indicated that plant height increased by wet planting, number of pods/plant and seeds/plant and yield was also higher in this method. Study of interaction between cultivar and sowing method showed that the highest pods/plant, seeds/plant and grain yield were associated to COS-16 in wet planting method
