| Abstract/Description: | Flue-cured Virginia tobacco is grown in an area of 28, 000 ha in Northern Light Soils (NLS) region of Andhra Pradesh under irrigated condition. Diammonium phosphate (DAP) and calcium ammonium nitrate (CAN) were the two important nitrogen sources widely used in the fertiliser schedule of Northern Light Soils. As per the Govt. of India’s policy, production of CAN is restricted. To find out an alternative cheaper nitrogen source to CAN for FCV tobacco in NLS and to study the effect of different nitrogen sources on yield, chemical composition and quality parameters of cured leaf, a field experiment was conducted for two consecutive years (2014-15 and 2015-16) during rabi at CTRI Research Station Jeelugumilli, West Godavari district, Andhra Pradesh. Twelve treatment combinations of Urea, Ammonium Sulphate (AS), Potassium Nitrate (KNO3) and Calcium Nitrate (CN) were compared with DAP + CAN (Recommended Dose), and 20-20-0, urea and AS combinations (Interim Fertiliser schedule recommended) in randomized block design with three replications. Based on the two years yield and chemical analysis for quality and nutrient composition it can be concluded that different sources of nitrogen (urea/AS)as basal dose and their combinations (AS/urea/urea+AS/ urea+AS+KNO3/ urea+AS+CN) as top dressing did not significantly influence the yield parameters (green leaf yield, cured leaf yield and grade index), quality parameters (nicotine, reducing sugars and chlorides) and also nitrogen composition of FCV tobacco in NLS of Andhra Pradesh. Hence any of these nitrogen fertiliser sources or their combinations can be used for FCV tobacco grown in Northern Light Soils. |
