Sonkar, Vikas and Kriti, Divya and Kumar, Vishal and Raj, Aniket (2025) The impact of integrated nutrient management on soil nutrient status and cauliflower (Brassica oleraceae) var. botrytis growth and yield. World Journal of Advanced Research and Reviews, 25 (3). pp. 602-607. ISSN 2581-9615

In two consecutive years (2023 and 2024), a field experiment was set up at the Faculty of Agriculture Science's experimental farm at United University to assess the impact of integrated nutrient management (INM) on soil fertility and cauliflower (Brassica oleracea var. botrytis L.) productivity. PGPR strains (Bacillus spp.) were used in studies that combined the usage of organic and inorganic fertilizers. The nine therapies, Absolute control (T1), 70% NPKM + 30% N through FYM and VC (50:50), 80% NPKM + 20% N through FYM and VC (50:50), 90% NPKM + 10% N through FYM and VC (50:50), 100% NPK + FYM (T5), 100% NPK + Vermicompost (T6), The NPKM values for T7, T8, and T9 are 50:50 of FYM and VC according to N content, 50:50 of FYM and VC according to N content, and 120% and 130%, respectively. With the exception of T1, T5, and T6, all treatments were subject to PGPR. Three replicates of the experimental setup were established using a randomized block design (RBD). In contrast to treatment T5 -100% NPK + FYM (RDF), the results showed that treatment T3 -80% NPKM + 30% N through FYM and VC (50:50) with PGPR greatly boosted the cauliflower yield by 22.91%. Following harvest, the soil's condition was evaluated, and the usage of fertilizers and PGPR together raised the soil's nutrient concentration.
