Effect of Nitrogen and Phosphorus on Yield Attributes, Seed Yield and Oil Content of Irrigated Safflower in Laterite Soil

Abstract

Effect of nitrogen (0, 60 and 120 kgfha) and phosphorus (O, 40 and 80 kg/ha) on the performance of safflower in laterite soil was studied. Application of 120 kg N and 40 kg P₂0₅/ha significantly improved the growth and yield components and increased the seed yield of safflower. Oil percentage in seeds reduced significantly with nitrogen more than 60 kg/ha but higher levels of phosphorus improved the oil content.
