Effect of different doses of phosphorus on growth and yield parameter of barley (Hordeum vulgare 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 Manjula K329 and 7 different treatments was laid out in Randomized Block Design with 3 replications. The study was assessed different doses of phosphorus with the application of Phosphorus through DAP on yield and nutrient partitioning and accumulation in plant parts productivity, along with economics of barley production. The results showed highest grain yield (33.21 q/ha), Straw yield (45.56 q/ha), Biological yield (78.77 q/ha) and Harvest index (42.16%) with the application of T6 (120% Recommended dose of Phosphorus). The study revealed that soil enrichment with (120% Recommended dose of Phosphorus) resulted in highest Net returns of Rs.44990.55 ha-1 and maximum B:C ratio (1.45).
