|Title:||Performance of Maize (Zea mays L.) to Fertilizer Levels and Foliar Nutrition Under Northern Transition Zone of Karnataka|
|Abstract:||A field study was conducted during kharif 2011 at Main Agriculture Research Station Farm, Dharwad, to study the response of maize to foliar fertilizers in combination with the application of soil applied fertilizers. The treatments consists of three fertilizer levels 100, 75 and 50 % RDF at, two concentrations (1.5% and 2%), sprayed at 4 stages (at 8th leaf, grand growth period, tassel emergence and dough stage) and 2 stages (at 8th leaf and tassel emergence) of plant growth. Urea and DAP foliar sprays @ 2% at two stages were kept as controls. The results revealed that, the 100% RDF (150:75:37.5 kg ha-1) along with foliar feeding of 2% starter dose at 8th leaf + grand growth period followed by booster dose at tassel mergence and dough stage recorded significantly increased growth, yield, total sugar content and nutrients uptake in maize. The magnitude of per cent increase of grain yield and total sugar content over control (100% RDF only) was 14.38 and 34.18 per cent, respectively. Whereas, the higher protein content (12.31%) was reported with foliar spray of urea @ 2 per cent at two stages in presence of 100% RDF. The 100 per cent RDF with 2 per cent foliar spray at four stages recorded the higher gross returns (` 73,039/ha) with the net returns of ` 48,527/ha and the higher net returns was recorded with the treatment 75 per cent RDF + 2 per cent foliar spray at four stages (` 50,269) with a gross returns of ` 70,811 ha-1. However, the higher BC ratio of 3.47 recorded in 75 per cent RDF with 2 per cent foliar spray two stages.|
