Effect of Nitrogen and Phosphorus Fertilizers on Nutrient Content and Uptake of High Quality Protein Maize (Zea mays L.) to under South Saurashtra Agroclimatic Zone of Gujarat

Abstract

An experiment was conducted to assess the “effect of nitrogen and phosphorus fertilizers on nutrient content and uptake of high quality protein maize (Zea mays L.) to under South Saurashtra agroclimatic zone of Gujarat” during summer, 2016 at the department of agronomy, college of agriculture, JAU, Junagadh. The experiment comprising of total twelve treatment combinations consisting four levels of nitrogen (Control, 90 kg N ha-1, 120 kg N ha-1, 150 kg N ha-1) and three levels of phosphorus (Control, 45 kg P2O5 ha-1, 60 kg P2O5 ha-1) laid out in Factorial Randomized Block Design replicated thrice. The results revealed that application of 150 kg N/ha significantly higher nitrogen, phosphorus and potassium content and uptake of grains and straw over control and 90 kg N/ha, while at par with 120 kg N/ha. Result showed that application of 60 kg P2O5 /ha significantly higher nitrogen, phosphorus and potassium content and uptake of grains and straw, being remained at par with 45 kg P2O5 /ha over control.
