Role of Vermicompost as Biofertilizer for the productivity of Cauliflower (Brassica oleracea) and Biopesticides against Nematode (Meloidogyne incognita)

Vermicompost singly and in binary combination with different biopesticide were used in agricultural field to control the infestation of nematode (Meloidogyne incognita) and high yield of cauliflower (Brassica oleracea) crop. Mixing of binary combination of vermicompost with neem oil (94%) in the soil caused significant reduction in M. incognita. The combination of garlic extract with different vermicompost caused 97% control of the nematode population. Vermicompost obtained from animal dung + gram bran with neem oil was very effective against the nematode M. incognita. Application of vermicompost with biopesticide increased the productivity of cauliflower crop more than eight times. The results clearly demonstrate that the use of vermicompost with plant product is more beneficial in organic farming. It is helpful to compensate the deficiency of nutrients in the soil as well as control of the harmful nematodes.
