Effect of spacing and organics on growth and yield of mothbean genotypes.

A field experiment was conducted at College of Agriculture, Bijapur in Northern Dry Zone of Karnataka to study the effect of spacing and organics on growth and yield of mothbean genotypes during kharif 2013. The experiment was laid out in randomized complete block design with factorial concept and replicated thrice. There were 14 treatments including 12 treatment combinations involving three mothbean genotypes (MBS-27, BJMB-1 and Local), two spacings (30 x 10 cm and 45 x 10 cm) and two organics (2.5 t/ha FYM and 1 t/ha vermicompost) along with two controls (local variety at 30 x 10 cm spacing with 10 : 20 kg NP/ha and local variety at 30 x 10 cm spacing with 10 : 20 : 10 kg NPK/ha). The local mothbean genotype gave significantly higher seed yield (796 kg/ha) at wider row spacing of 45 x 10 cm compared to 30 x 10 cm. Application of 1 t/ha vermicompost recorded significantly higher seed yield (714 kg/ha) compared to 2.5 t/ha FYM. The interaction of mothbean local variety at spacing of 45 x 10 cm with application of 2.5 t/ha FYM produced significantly higher seed yield (983 kg/ha), seeds per pod (7.36), pods per plant (78.73), total dry matter at 30, 50 and 70 DAS (2.25, 12.00 and 30.45 g/plant, respectively), branches per plant (8.73), plant height (90.8 cm) compared to other treatment combinations. It can be concluded that for dry land situation, local mothbean genotype can be recommended at a spacing of 45 x 10 cm with 2.5 t/ha FYM application. [ABSTRACT FROM AUTHOR]
