Effect of Bio-Fertilizers and Flumioxazin on Microflora and Yield of Groundnut (Arachis hypogaea L.) in Alfisol of West Bengal

Abstract

Herbicide is the most important input in the modern agriculture. The use of herbicides has been expanding more rapidly than that of other pesticides. The injudicious application of herbicides in agriculture causes the contamination of the soil with toxic chemicals and become harmful to the microorganisms, plant, wildlife and man. In view of the above a field experiment was conducted during rabi season of 2015-16 with the groundnut variety TAG-24 with twenty four treatment combination in three replications. The result of this experiment showed that the application of herbicide Flumioxazin along with different combinations of biofertilizers PSB, Rhizobium and Azotobacter have no significant adverse effects in the physico-chemical properties of soil (pH and EC), available nitrogen content, microflora population (NFB, PSB, fungi, actinomycetes) and pod yield of Groundnut.
