Effect of Organic Manures, Inorganic Fertilizers and Microbial Innoculants on Yield and Economics of Coleus (Coleus forskohlii Briq.)

摘要

Application of recommended dose (RD) NPK + RD FYM + Azotobacter + phosphorus solubilising bacteria + vesicular arbiscular mycorrhiza (T_(11)) recorded significantly higher values for number of tuberous roots plant~(-1) (12.57), length of tuberous roots (12.26 cm), girth of tuberous roots (1.64 cm), fresh weight of tuberous roots plant~(-1) (277.50 g) and dry weight of tuberous roots plant~(-1) (39.39 g). It also recorded highest fresh (6.76 kg and 11.27 t) and dry tuberous root yield (0.96 kg and 1.60 t) plot~(-1) and hectare~(-1), respectively, dry matter per cent in tubeious roots (14.02 %), net income (Rs. 39.064.50 ha~(-1)) and cost : benefit ratio (1:1.95).
