Biofertilizers formulations and their effect on morphological characters in greengram (Vigna radiata L.)

Abstract

The investigations to evaluate the effect of different formulations of biofertilizers on plant growth parameters of Greengram, variety (MGG –295) and the field experiment was conducted at water technology centre fields, college farm, College of Agriculture, PJTSAU, Rajendranagar, Hyderabad, Telangana during kharif 2016 – 2017. From the results, the plant height and Dry matter production at 30, 45, 60 DAS and at harvest stage respectively (27.40, 39.00, 46.33, 47.07 cm) and (8.60, 15.80, 22.30 and 18.30 g plant-1 ) significantly increased in seed treatment with liquid based bio fertilizers with combination of 100 % RDF and LBBF Seed treatment when compared to all other treatments. The significantly highest root length of greengram was noticed due to combined seed treatment with carrier based Rhizobium and PSB bio-inoculants at 30, 45, 60 DAS and at harvest stage was recorded 12.63, 17.60, 22.83 and 23.50 cm respectively. The soil treatment with LBBF along with 100 % RDF application recorded significantly highest number of root nodules and nodule dry weight i.e. (18) and (30) nodules plant-1 and 0.18 and 0.30 nodule dry weight g plant-1 at 30 and 45 DAS respectively when compared to all other treatments. These results provide baseline information to promote an eco-friendly and sustainable agriculture.
