An investigation was conducted to find out the effect of different organic manures on growth, yield and quality of makoi (Solonum nigrum L.). The experiment comprised of 13 treatments consisting of different combinations of organic manures (FYM @ 10, 15 and 20 t, vermicompost @ 0.5 and 1.0 t and neem cake @ 0.5 and 1.0 t ha -1 ) and FYM 10 t + NPK @ 100:50:50 kg ha -1 through inorganic fertilizers. Maximum plant height, number of branches per plant, plant spread, number of leaves per plant, leaf area and total dry matter accumulation were recorded with the application of FYM 20 t + vermicompost 1.0 t + neem cake 1.0 t ha -1. Fresh and dry herbage yield were also maximum with the same treatment. However, application of FYM 20 t + vermicompost 1.0 t + neem cake 0.5 t ha -1 resulted in maximum alkaloid content and alkaloid yield, whereas, the highest net returns of Rs. 34,000 ha -1 and benefit to cost (B:C) ratio of 1.80 was recorded with the application of FYM 20 t + vermicompost 1.0 t + neem cake 1.0 t ha -1.

Integrated nutreint management (INM) is the judicious use of one or more sources of plant nutrients either individual or in combination. It mainly aims at achieving maximum fertilizer use efficiency, besides reducing toxic residues in both soil and plant. In this view a field experiment was conducted during the year 2002 - 2003 at Department of Horticulture, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bangalore to know the influence of different manures and fertilizers on grrowth, yield and quality of makoi (Solanum nigrum L.), a very important, upcoming medicinal plant. The treatments consisted of organic manures (FYM, city compost and poultry manure) and inorganic fertilizers alone and in different combinations. The results revealed that the plants suppled with 75 per cent nutrients through fertilizers + 25 per cent through poultry manure recorded maximum plant height, number of branches, number of leaves, leaf area, fresh and dry yield of the whole herb. Whereas, the highest alkaloid content was recorded in the plants supplied only with poultry manure and the maximum alkaloid yield was in plants supplied with 75 per cent nutreints through fertilizers + 25 per cent through city compost.
