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

摘要

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 com during kharif season of 2015 season with seven treatments comprised of 100% recommended dose of fertilizer (RDF, 150:60:60 N, P_2O_5 and K_2O kg ha~(-1)), 25% N supplemented throughFarm 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 of2015-16 and 2016-17 for hyacinth bean and the treatments of 100% RDF (20 kg N, 50 Kg P_2O_5 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 , maximum pod length, pod weight and higher pod yield, respectively over 100% RDF alone, 75% RDF with or without seed treatment.
