 ABSTRACT

The study was conducted to study the influence of soil applied plant derivatives of tree species combined with mineral fertilizer on microbial populations in cauliflower (Brassica oleracea var. Botrytis L). A field experiment was conducted during rabi season of 2018-19 and 2019-20, at experimental farm of University of Horticulture and Forestry, Nauni Solan. Eight treatment combinations viz. melia fruit powder, pomegranate rind powder, commercial neem cake, calcium carbide (CaC2) @ 10 and 20 g kg-1 of soil, respectively and control were incorporated to study with three replications. Randomized block design was used to maintain heterogeneity. Results revealed that all the different treatments improved the microbial populations over the control treatment. Treatment of pomegranate rind powder@ 10 g kg-1 soil documented highest bacterial count (20.10 and 19.92 x 105 cfu g-1soil), fungal count (4.48 and 4.43 x 103 cfu g-1soil) and actinomycetes (3.45 and 3.39 x 103 cfu g-1soil) during 2018-19 and 2019-20, respectively. However, the lowest count was recorded in control treatment. Moreover, melia fruit powder application also recorded higher microbial count in the soil as compared to synthetic inhibitor (CaC2). Incorporation of natural inhibitors showed higher response and therefore sustained higher microbial populations under cauliflower.

Key words: Nitrification inhibitors, Microbial population, Cauliflower, Sustainable agriculture.
