Investigation of some production factors on yield and quality of dry beans

Abstract

The correlation between plant density and yield average shows that the volume of yield increases in varieties of large and medium-size seeds up to a plant density of 285-400 thousand/ha, after which it declines. On the basis of the results, yield averages at plant densities of 285-334 thousand plant/ha are 0.17 t/ha higher than those achieved at low density (200 thousand plant/ha). High levels of potassium fertilizer did not enhance the yield of dry beans. With adequate-water supply the high level of potassium decreased the number of pods and seeds per plant compared with a basic level of fertilizer, which could ensure 2.5 t/ha yield.
