Abstract
A field experiment was carried out during 1989 and 1990 to study the response of summer greengram (Phaseolus radiatus L.) to Rhizobium inoculation, plant population and phosphorus levels. Rhrzobium inoculation increased the dry-matter accumulation, number of nodulesiplant, nodule weight/ plank nutrient uptake and yield attributes. Plant population at 30 cm row spacing increased the grain yield (18.5%) and found superior to 40 and 20 cm spacings. Phosphorus @ 40 kg P20J/ha increased the grain yield by 17.2% over the control. Interactions among inoculation and phosphoms, row spacing and phosphorus and inoculation and row spacing were also found significant for yield attributes, grain yield and nutrient uptake respectively.
