Effect of integrated nutrient management practices on growth, yield attributes and yield of hyacinth bean in baby corn (Zea mays. L) – hyacinth bean (Lablab purpureus var typicus) cropping system

A field experiment was conducted at Horticultural Research Station, Adilabad, Telangana State, India during kharif and rabi seasons of 2015-16 and 2016-17 to study the effect of INM practices on hyacinth bean in baby corn-hyacinth bean cropping system. The experiment was laid out in a randomized block design for baby corn during kharif season of 2015 season with seven treatments comprised of 100% recommended dose of fertilizer (RDF, 150:60:60 N, P2O5 and K2O kg ha-1), 25% N supplemented through Farm Yard Manure or vermicompost + 75% RDF with or without soil application of Azospirillum and Bacillus megaterium @ 5 kg ha-1 each and unfertilized control with 3 replications. Each main treatment was divided into four subplots during rabi season of 2015-16 and 2016-17 for hyacinth bean and the treatments of 100% RDF (20 kg N, 50 Kg P2O5 ha-1) and 75% RDF with or without Bradyrhizobium @ 500 g ha-1 (seed treatment) were imposed in split plot design. Mean data of two rabi seasons revealed that seed treatment with Bradyrhizobium in conjunction with 100% RDF recorded significantly higher plant height, leaf area index, nodule number, dry matter production at harvest, higher number of pods plant 1, maximum pod length, pod weight and higher pod yield, respectively over 100% RDF alone, 75% RDF with or without seed treatment.
