dc.description.abstractABSTRACT The present investigation ‘Insect-pests, natural enemies and soil micro flora in cabbage under Zero Budget Natural and Conventional Farming systems’ was conducted during the year 2018-19 at YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. During the study period, as many as 7 insect-pests species viz. cabbage aphid, Brevicoryne brassicae (L.), green peach aphid, Myzus persicae (Sulzer), cabbage head borer, Hellula undalis (Fabricius), diamondback moth, Plutella xylostella (L.), cabbage butterfly, Pieris brassicae (L), greenhouse whitefly, Trialeurodes vaporariorum Westwood and flea beetle, Phyllotreta sp. were recorded from Zero Budget Natural Farming (ZBNF) and Conventional Farming (CF) systems. Seasonally, the pest population in the two farming systems did not differ significantly. The natural enemies diversity was higher in ZBNF (7 species) than CF (6 species). In ZBNF system, Diadegma semiclausum (Hellen) was an additional species, besides six other common species viz. Coccinella septempunctata L., Hippodamia variegata (Goeze), Episyrphus balteatus (De Geer), Eupeodes frequens (Matsumura), Metasyrphus confrator (Wiedemann) and Diaeretiella rapae (Mc’Intosh) common in both farming systems. The biological and biochemical properties of soil were also studied, in which ZBNF enhanced the soil micro flora significantly over CF system (bacteria: 3.03; fungi: 12.5; actinomycete: 12.4%). The soil enzyme activities viz. dehydrogenase, phosphatase and urease were also enhanced by 34.29, 7.31 and 10.51 per cent, respectively, in ZBNF over CF system. ZBNF system proved as efficient as CF in the management of insect-pests of cabbage under their respective management practices. However, it added more soil micro flora and enhanced enzyme activities more than CF and thus leaving more fertile soil for next crop.en_US
