Abstract
The experiments were conducted on cultivators' fields to study the response of nitrogen, phosphorus, potash, and zinc on the grain yield of wheat in Kutch district during 1977-78 to 1979-80 in rabi season. From the results of three years, it was revealed that the grain yield increased significantly with increasing rate of nitrogen from N₁ to N₃ kg/ha and that of phosphorus from 20 to 60 kg P₂O₅/ha. However, the response of potassium was significant, while no significant response was observed with the application of zinc sulphate. The highest grain yield (36.61 q/ha of J-18 and 39.26 q/ha of J-24) was obtained with the application of N₁₀₀ P₆₀ K₄₀ during 1977-78.
