Studies on Carrier and Liquid Based Bio-Fertilizer on Performance of Lentil (Lens esculenta) in Alluvial Soil of West Bengal

Abstract

Lentil (Lens culinaris) is an important crop of sustainable agriculture system having good nutritional value. Liquid biofertiliser formulations are known to have better result at field level. A field experiment was conducted in the gangetic alluvial soil belt of West Bengal to study the performance of lentil cv WBL 77 (Moitree) at farmer’s field in Krishnaganj block, Nadia, WB in the rabi season 2020-21. The experiment was conducted in randomised block design having ten treatments replicated thrice. Carrier and liquid based formulations of rhizobium and phosphorus solubilising biofertilisers were used. The results revealed that growth and yield parameters responded positively when lentil were grown with different combinations of biofertilizer and inorganic fertilizers. Recommended dose of fertilizers (RDF) + liquid based rhizobium and PSB and was found to be better in respect to growth, nodulation and yield attributes. However, was statistically at par with treatment RDF + Carrier based Rhizobium & PSB. Plots where 75% RDF + liquid or carrier based biofertilisers were applied were observed to be at par with treatments where RDF and any one biofertilier were applied. Based on the study, we may infer that liquid biofertiliser formulations can have better effect on lentil growth, nodulation and yield.
