Abstract

A field investigation was carried out at Research Cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur during kharif season of 2013 to study the effect of four genotypes viz. KU 96-3 (V1), Indira Urd Pratham (V2), IU-02-01 (V3) and IU-02-03 (V4) and three planting geometry viz. 30 cm x 5 cm (S1), 30 cm x 10 cm (S2) and 30 cm x 15 cm (S3) on growth and nodulation pattern of urdbean in Chhattisgarh plains. Results revealed that growth parameters viz. plant height, branches plant-1, leaf area, number of nodule and dry weight of nodules were the highest under urdbean genotype Indira Urd Pratham which ultimately gave highest yield. Among planting geometry 30 cm x 10 cm (S2) spacing was found to be better yielder than 30 cm x 15 cm (S3) and 30 cm x 5 cm (S1) spacing. However, wider planting geometry of 30 cm x 15 cm (S3) was found to be superior in terms of individual growth and nodulation pattern. But finally, seed yield was highest in planting geometry of 30 cm x 10 cm (S2) due to more number of plants per unit area. Urdbean genotypes sown with a planting geometry of 30 cm x 5 cm (S1) recorded maximum stover yield.
