Abstract

A field experiment was conducted during 2010 and 2011, under three replications. One row in Furrow Irrigated Raised Bed/ every furrow irrigation increased plant height by 7.94 %, stem girth by 46.47 per cent, and dry matter at maturity by 23.69 % over conventional sowing/ conventional irrigation. Similarly, number of leaves increased by 19.26 and 24.65 % leaf area by 25.83 and 26.65 %, over conventional practice at 60 and 90 days after sowing, respectively. Besides, it resulted 1.91 and 1.82 % higher total chlorophyll over conventional practice at 30 and 60 days after sowing, respectively and increased grain by 60.72 %, biological 42.44 % and stover yield by 30.2 % over conventional practice and also resulted 3.43 higher starch and 12.05 % protein content over conventional practice. Zea_mays_L.-maizOne row in FIRB/ every furrow irrigation, had 62.1, 51.5 and 42.9 % higher uptake for nitrogen, phosphorus and potassium over conventional practice of crop establishment, respectively. Though, growth, yield attributes and yields were recorded highest with 200 kg N level, but the differences remained non significant with 150 Kg N. Application of 150 kg N/ha out yielded 10.78, 21.71 and 2.58 % higher biological, grain and stover yield over 100 kg N/ha. To harness existing agri-resources and attaining higher quality and quantity of maize production, the crop should be raised on FIRB and irrigated in each furrow and should be fertilized with 150 kg N/ha.
