Effect of Bavistin Foliar Spray on VAM Colonization and Growth Parameters in Six Groundnut Cultivars

The impact of application of plant protection chemical bavistin as foliar spray on AM colonization and plant growth parameters like ischolar_main length, shoot length, shoot fresh weight, shoot dry weight, nodule number and nodule weight of six groundnut cultivars viz., 87779 ICGV, CS 52, FDRS 4, 414332, Gangapuri and J 11 was studied. For the study, the cultivars were raised in field plots. The phosphorus and nitrogen contents of plant material was also estimated. The bavistin spray significantly decreased the per cent infection and number of spores in ischolar_mains of six cultivars at 50 days, 70 days and 90 days samplings. Except the shoot dry weight at 70 days and 90 days samplings, all the other parameters studied including ‘P’ and ‘N’ contents were negatively affected by the bavistin foliar spray.
