Abstract:
A Research was carried out under Prayagraj agro-climatic conditions at the experimental field of Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, U.P during the year 2021 and 2022. The experiment was designed in a randomized block design with consisting 17 treatments and 3 replications. The seventeen treatments were allocated randomly to each plot. The primary objective of this study was to compare the growth and yield of cauliflower grown under different levels of Inorganic fertilizers, organic manures, and biofertilizers. maximum plant height noted in treatment T₄ (13.43, 36.10 and 46.50 cm at 30, 45 and 60 DAS, respectively), maximum number of leaves also noted in treatment T₄ (7.65, 11.55 and 19.61 at 30, 45 and 60 DAS, respectively) and were all reported in T4 (Biochar 20t + 75% NPK + PSB + Azotobacter) over both years and also the pooled analyzed data. On the other hand, T₁₇-100% NPK (Control) had the lowest values for these indicators. In relation to yield attributes maximum diameter of curd (17.34 cm), weight of trimmed curd T₄ (1050.60 g) total weight of plant without roots (40.50 g), curd yield per plot (8.00 kg/plot), and yield per hectare (35.56 t/ha) during both the years and pooled were recorded in T₄- Biochar 20t + 75% NPK + PSB + Azotobacter. Whereas the minimum value regarding these parameters were recorded in T₁₇-100% NPK (Control).
