Optimizing Agronomic Management of Wheat Varieties UP 2338, PBW 343, and VL 804 for Sustainable Productivity and Food Security in Sikkim’s Diverse Agro-Climatic Conditions

Abstract Wheat productivity in Sikkim remains below the national average due to fragmented landholdings, soil acidity, erratic rainfall, and limited adoption of scientific agronomic practices. This study evaluated three widely cultivated wheat varieties—UP 2338, PBW 343, and VL 804—under optimised and farmer-managed agronomic practices across Sikkim’s mid- and high-hill agro-climatic zones. A two-year field experiment using a Randomised Complete Block Design (RCBD) assessed growth dynamics, yield attributes, grain quality, soil health parameters, and economic returns. Optimised management significantly enhanced grain yield (18–27%), improved protein content (0.6–1.1%), and increased benefit–cost ratio (1.48 to 2.12). Among varieties, VL 804 performed best in high elevations, while PBW 343 showed superior performance in mid-hills under improved nutrient scheduling. Results provide region-specific, evidence-based recommendations for sustainable wheat production in Sikkim.
