Effect of different doses of nitrogen on growth and yield parameters of wheat (Triticum aestivum L.)

Abstract

The experiment was carried out at the Agricultural Research Farm of National Post Graduate College Barhalganj, Gorakhpur, U.P. During rabi 2022-23. This experiment consisted of wheat variety PBW-343 and 7 different treatments was laid out in Randomized Block Design with 3 replications. The study was assessed different doses of nitrogen with the application of Nitrogen through Urea on yield and nutrient partitioning and accumulation in plant parts productivity, along with economics of wheat production. The results showed highest grain yield (60.32 q/ha), Straw yield (65.26 q/ha), Biological yield (125.58 q/ha) and Harvest index (48.03%) with the application of T5 (100% Recommended dose of Nitrogen). The study revealed that soil enrichment with (100% Recommended dose of Nitrogen) resulted in highest Net returns of Rs.123841.80 ha-1 and maximum B:C ratio (3.06).
