Abstract:
The field experiment was carried out at the farmer’s field in Chella Kamarpara village, Chella G.P, Chella Mouza of Illambazar Block, Birbhum, West Bengal which is situated at 23o 37.374’ latitude and 87o37.170’E longitudes with an average altitude of 58.9 m above mean sea level under sub-humid, sub-tropical belt under the prevailing climatic conditions of West Bengal during the Kharif season of 2013. The experiment consisted of the five levels of nutrient management i.e., N1: State recommendation (150:75:75), N2: Nutrient expert (NE) recommendation (120:34:51), N3: Farmers practices (80:40:40), and N4: Basal application of 50:75:75 with split N application on basis of LCC (leaf colour chart), N5:control and two level of varieties viz. V1: Sona and V2: Rajkumar, the total number of treatment combinations are ten, which were replicated thrice and was laid out in factorial randomized block design (FRBD). To evaluate the effect of nutrient management on the growth, productivity and economics of hybrid maize cultivation. Nutrient management has played an important role in achieving sustainability of grain production. The chemical fertilizer consumption coupled with their limited production, fertilizer cost, soil health and pollution have given rise to interest in precision nutrient management tools. It was the found that the Growth, productivity, nutrient uptake and economics of hybrid maize (Zea mays L.) as influenced by precision nutrient management which was significantly affected by different level of nutrient management and varieties. Whereas, LCC based application of fertilizer gave better result than all other treatment but it was also statistically at par with Nutrient expert based recommendation.
