Performance Evaluation of Different Indian Mustard (Brassica juncea) Varieties to Various Fertilizer Rates under Late Sowing Irrigated Conditions in the Jammu Region

Abstract

A field experiment was conducted during the rabi season of 2020 at the Research Farm, Division of Agronomy, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, to evaluate the effect of Indian mustard (Brassica juncea L.) varieties, farmyard manure (FYM) application and different fertilizer levels on productivity and profitability under late sown irrigated conditions. The treatment consisted of four varieties viz., V1-RSPR 69, V2-Pusa Mustard 26, V3-RVM 2 and V4-NRCHB 101 in main plot; FYM @5 t ha-1 and no FYM in sub plot and three fertilizer levels in sub-sub plots i.e., F1-NPKS (60:30:15:20 kg ha-1), F2-NPKS (80:40:20:25 kg ha-1) and F3-NPKS (100:50:25:30), which were laid out in split-split plot design with three replications. Results indicated that variety RVM-2 recorded significantly higher growth, yield attributes and seed yield which were statistically at par with NRCHB 101. Application of FYM @ 5 t ha-1 significantly improved growth and yield of mustard compared to no FYM. Similarly, fertilizer aapplication at 100:50:25:30 kg ha-1 (N:P2O5:K2O:S) resulted in significantly higher growth, yield attributes and seed yield and was statistically comparable with 80:40:20:25 kg ha-1. The combination of variety RVM-2, FYM@ 5t ha-1 and fertilizer dose of 80:40:20:25 kg ha-1 recorded the highest B: C, indicating its suitability for maximizing productivity and profitability of Indian mustard.
