 ABSTRACT

A field experiment was conducted on the performance of genotypes and row spacings with nipping practices and different levels of nutrients at the Agricultural College Farm, UAS, Raichur, during kharif 2016 and 2017 in the clay soil. Pooled mean of two years indicated that DCH-519 recorded significantly higher total number of productive spikes plant-1 (9.04), number of capsules spike-1 (35.25), bean yield (1311 kg ha-1), net returns ( 21,074 ha-1) and BC ratio (2.24) as compared to DCH-177. Among the row spacings, 120 cm with nipping recorded significantly higher number of capsules spike-1 (42.10) whereas the bean yield (1700 kg ha-1), net returns ( 31899 ha-1) and BC ratio (2.83) was significantly higher with a row spacing of 90 cm with nipping. Similarly 100 per cent RDF with sulphur recorded significantly higher total number of productive spikes plant-1 (9.33), number of capsules spike1 (36.14), bean yield (1356 kg ha-1) and net returns ( 21831 ha-1) whereas BC ratio was significantly higher with 100 per cent RDF without sulphur (2.53). Hence, on the basis of the results obtained in the pooled data of the two years, genotype DCH-519 with a row spacing of 90 cm with nipping and 100 per cent RDF was found to be economical and better option to obtain higher bean yield.

Key words: Nipping, Ricinus communis, Geometry and Bean yield, Nutrient levels
