Effect of site specific nutrient management on growth, productivity and macro nutrients in maize (Zea mays L.) under southern Rajasthan conditions.

摘要

A field experiment was conducted during kharif 2010 at Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, Udaipur to study the effect of site specific nutrient management on yield, productivity and macro nutrients realisation on maize crop and revealed that application of SSNM treatment recorded significantly higher in plant height, dry matter accumulation at harvest, number of grains/cob, grain weight/plant, test weight, grain, stover and biological yield. This treatment recorded 62.40, 50.52 and 55.02% higher grain, stover and biological yield over control. This treatment also gave maximum protein content, N, P, K content in grain and stover as well as their uptake by grain, stover and total by the crop which remained at par with SSNM-potash and found significantly superior over rest of the treatments. SSNM treatment recorded maximum total N (129.56 kg/ha), P (28.64 kg/ha) and K (90.48 kg/ha) uptake by the maize crop.
