Effect of Integrated Use of Organic Manures and Inorganic Fertilizers on Yield and Economics of FCV Tobacco - Baby Corn Sequence

摘要

A field experiment was conducted at the Agronomy Field Unit, Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore during kharif season of the year 2004-2005. The main objective of the experiment was to study the effect of integrated use of organic manures and inorganic fertilizers on the yield and economics of FCV tobacco-baby corn crop sequence. The experiment was laid out in Randomized Complete Block Design, with three sources of organic manures and four levels of inorganic/ organic fertilizers. All the recommended cultural practices were followed in raising the crops except fertilizer application to succeeding baby corn crop. The highest cured leaf yield and top grade equivalent yield of FCV tobacco crop recorded with 50per cent of recommended N through inorganic fertilizer and through glyricidia (1756 kg ha~(-1), 955 kg ha~(-1) respectively). Whereas, 100 per cent of recommended N through glyricidia recorded higher husked baby corn and green fodder yield (6537 kg ha~(-1), 19.8 t ha~(-1), respectively) of suceeding baby corn crop. 50 per cent of recommended N through inorganic fertilizer and through glyricidia recorded higher gross returns, net returns and B : C ratio.
