Effect of sowing date and soil type on yield, yield components and survival of dry beans (Phaseolus Vulgaris L.)

Abstract

SummaryField experiments were conducted on clay and sandy clay-loam soils to investigate the effects of sowing date on the incidence of plant losses. Early sowing dates from 2 to 23 September resulted in very low seed yield (360 kg/ha) mainly because fewer plants survived. High air temperature increased the rate of plant death which was highly correlated with degree days, r = +0·95.Number of plants/m2 was the predominant factor determining seed yield and number of pods/plant could not compensate for loss of plants.
