dc.description.abstractA field experiment was conducted during Kharif, 1999 at Main Research Station, Dharwad with two pigeonpea genotypes and seven planting geometries (population). The genotypes, Maruti (1469 kg/ha) and PET-3-19 (1445 kg/ha) recorded on par grain yield, yield attributes viz., number of pods per plant, number of seeds per pod, pod weight per plant, seed yield per plant, 100-seed weight, harvest index and seed protein content. While, few growth characters viz., total number of branches, dry matter accumulation in leaves, total dry matter production, plant spread per plant and light transmission ratio were found significant only at certain stages of growth. But, there was significant difference in plant height, days to flower initiation, 50 per cent flowering and physiological maturity, the highest being with PET-3-19. The geometry had significant effect on all the growth and yield attributes. A geometry of 120 cm X 30 cm with a population of 27,777 plants per ha recorded the highest yield (1544 kg/ha) and yield attributes viz., number of pods per plant (155.7), number of seeds per pod (3.2), pod weight per plant (99.033 g), seed yield per plant (53.90 g), 100-seed weight (9.130 g) and harvest index (27.62 %). It also recorded the highest per plant number of primary, secondary and total branches, dry matter accumulation in leaves, stem and reproductive parts, plant spread and LTR. But, the plant height, LAI, LAD and flower drop were highest with a population of 83,333 plants per ha with the geometry of 120 cm X 10 cm and 60 cm X 20 cm. Thus, it can be concluded that the genotype Maruti in a geometry of 120 cm X 30 cm with a population of 27,777 plants per ha is optimum to get higher yield and net return in vertisols of Northern Transitional Zone of Karnataka.en_US
