Abstract

A field experiment was conducted during rainy season of 2010 and 2011 at Udaipur to ascertain suitable nitrogen level (125, 150 and 175 kg N/ha), appropriate schedule of nitrogen application (3, 4 and 5 splits) with and without sulphur (control and 40 kg S/ha) for quality protein maize (Zea mays L.) in soils having medium fertility status. Results pooled over two years indicated that dry matter accumulation recorded under 175 kg N/ha was significantly higher over 150 and 125 kg N/ha at successive growth stages, while crop growth rate increased significantly upto 150 kg N/ha. Application of 175 kg N/ha significantly increased yield attributing parameters consequently yield and nutrient uptake, N status of soil and proved economically profitable to 150 and 125 kg N/ha. Staggering of nitrogen application in 4 equal splits as 25% at sowing+25% at 4-6 leaf stage+25% at knee high stage+25% at 50% tasseling stages showed marked improvement in growth, yield attributes, yield, nutrient uptake, N status of soil and proved economically beneficial compared to recommended 3 splits of nitrogen application. Application of 40 kg S/ha affirmed potential role in enhancing productivity of quality protein maize and also proved economically profitable compared to control
