Effect of de-topping and nitrogen doses on economics of maize (Zea mays L.) Varieties

Abstract

The experiment was conducted at research Farm, Indira Gandhi Agriculture=University, Raipur (C.G.) during Kharif 2018 to study the effect of de- topping and nitrogen levels on economics of maize (Zea mays L.) with two maize varieties (African tall and hybrid 25K55) practicing de-topping and no de-topping in main plots and four nitrogen levels in sub plot under split plot design and replicated thrice. The results of experiment on response of de-topping and nitrogen levels revealed that the minimum cost of cultivation Rs 31725 without de-topping in African tall, maximum gross return Rs ha-1 was found in African tall with de-topping Rs 85478 and maximum net return Rs 53537 and B:C ratio 2.65 was recorded highest when no de-topping was done in African tall. Similarly, all these characters were also superior under treatment receiving 150 kg N ha-1. The least value was obtained in unfertilized treatment.
