Abstract:

A field experiment was conducted at Agricultural College Farm, Mahanandi on sandy loam soils to know the response of maize to secondary and micronutrients with pioneer hybrid P3369. The experiment comprised of nine treatments consisting of recommended dose of fertilizer of NPK through soil application and foliar application of secondary and micronutrients at 20 days after sowing (DAS). Foliar application of micronutrients along with RDF recorded significantly highest grain yield of 4702 kg ha-1 and stover yield of 7318 kg ha-1 as compared RDF (3773 and 6430 kg ha-1 of grain and stover yield, respectively). Yield attributes viz., number of cob plant-1, Number of rows cob-1, Number of grains row-1, cob length, cob girth, hundred grain weight were highest with the application of RDF + foliar application of ZnSO4 @ 0.1per cent (T7). The highest grain and stover yields was recorded with RDF + foliar application of micronutrient mixture @ 0.2 per cent which was on par with RDF + foliar application of ZnSO4 @ 0.1per cent (T7) and superior over recommended dose of fertilizers and control. The treatment with RDF + foliar application of micronutrient mixture @ 0.2 per cent (T9) recorded the highest gross returns, net returns and B:C ratio.
