Effect of granulated lime and bio-inoculants on the productivity of French bean (Phaseolus vulgaris L.) under hilly zone of Karnataka

Abstract

A field experiment was conducted at College of Horticulture, Mudigere, Chikamagalur district, Karnataka to investigate the effect of granulated lime and bio-inoculants on the productivity of French beans (Phaseolus vulgaris L.) under the hilly zone of Karnataka during late rabi season 2019-20. The experiment was laid out in RCBD with nine treatments replicated thrice. The treatments consisted of granulated lime at three levels (100, 75 and 50 % LR) and agriculture lime at 100 % LR, with and without bio-inoculants. RDF and FYM were common to all treatments. The liming materials were applied based on SMP (Shoemaker, Mclean and Pratt) buffer method. The results revealed that significantly higher plant height (51.1 cm), number of branches (6.88 plant-1), number of leaves (26.42 plant-1), chlorophyll content (49.64 SPAD) and dry matter accumulation (19.34 g plant-1), pod number (21.43 plant-1), pod length (15.67 cm), pod weight (177.17 g plant-1), green pod yield (12.93 t ha-1) and stover yield (2.93 t ha-1) over control.
