Abstract


A field experiment was conducted at Shimoga during  Kharif, 2007 to study the variation in growth and productivity of  FCV tobacco grown under organic, chemical and integrated crop management systems. The highest cured leaf yield (1086 kg ha-1)was observed with recommended  package of practices and lowest in organic system-III with pressmud and crop residue. Similar trend was observed with respect to quality of FCV tobacco in terms of top grade equivalent. The superiority of recommended package of practices with chemical fertilizers and FYM over the organic systems was evident with respect to growth parameters and biomass yield. It was observed that the number of leaves recorded were highest (24.8) with recommended package of practices involving fertilizers and FYM. The highest stalk yield(697.3 kg ha-1) was recorded with recommended package of practices and the lowest in organic system-II with pressmud. The biomass yield varied significantly from 1163 to 2027 kg ha-1 in organic -III and package of practices respectively.
