Abstract

Background

Inclusion of legume crops in multiple cropping systems has become crucial to increase the sustainability of agroecosystems. Short duration mung bean can be easily fitted into many cropping sequences which also turns the farming highly remunerative along with strengthening the sustainability. The current study was aimed to evaluate residual effect of nutrient management on performance of summer mung bean in a gobhi sarson - summer mung bean sequence.

Methods

During the period of 2016-17 and 2017-18 different doses of chemical fertilizers (NPK), combination of FYM with chemical fertilizers and different biofertilizers alone as well as their combination were evaluated to find out their residual effect on summer mung bean grown after the gobhi sarson crop. The data on growth parameters, yield attributes viz; plant height, dry matter accumulation, number of branches per plant, number of pods per plant, number of seeds per pod, 100- seed weight were collected. The seed and biological yield from different treatments was also evaluated.

Result

All growth parameters, yield attributes, seed and biological yield of summer mung bean were affected significantly with chemical fertilizers, their combined application with FYM treatments as well as different biofertilizers treatments applied to preceding gobhi sarson. Growth and yield significantly improved with each incremental dose of chemical fertilizers i.e. from 0 to 50% RDF, 50 to 75% RDF, 75 to 100% RDF while 50% RDF + FYM @ 10 t ha-1 being the best treatment. The treatment with consortium showed significantly maximum yield and growth parameters followed by combined application of Azotobacter + PSB, PSB alone, Azotobacter alone and no inoculation treatments, respectively.
