Effect of Liquid Biofertilizer with or Without Vermicompost on Growth and Yield of Field Pea (Pisum sativum) Grown under Laterite Soil of West Bengal

Abstract

A field experiment was conducted at agricultural farm of Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan, West Bengal in rabi season of 2022-23 using the field pea cultivar IPFD 10-12. The experiment was laid out in a factorial randomized block design with two factors and ten treatment combinations. The first factor consists of vermicompost i.e., V1: With vermicompost, V2: Without vermicompost and the second factor consists of INM i.e., N1: Absolute Control, N2: 100 % RDF, N3: Liquid biofertilizer consortium, N4: 75 % RDF+ Liquid biofertilizer consortium and N5:100 % RDF + Liquid biofertilizer consortium. The results showed that application of vermicompost 6 t/ha (V1) recorded higher growth attributes like plant height, leaf area index and dry matter accumulation at 30, 60, 90 and at harvest, yield components like number of pods per plant (10.77), number of seeds per pod (4.22) and 1000 grain weight (125.41 g), seed (1535.91 kg/ha) and stover yield (1535.91 3487.63 kg/ha) while compared to no vermicompost application (V2). Crop fertilized with 75% RDF + liquid biofertilizers (N4) showed more growth attributes like plant height, leaf area index and dry matter accumulation at 30, 60, 90 and at harvest, yield components like number of pods per plant (12.19), number of seeds per pod (4.61) and 1000 grain weight (127.34 g), seed (1624.05 kg/ha) and stover yield (3550.82 kg/ha) which was at par with 100% RDF + liquid biofertilizers (N5).
