Abstract
An investigation was carried out to study the influence of different levels of NPK on growth, yield and alkaloid content of makoi (Solanum nigrum L.) under hill zone-9 of Karnataka at Horticulture Research Station, Thirthahalli, University of Horticultural Sciences, Bagalkot during the year 2013-14. The results revealed that, application of NPK fertilizer @ 125:75:75 kg /ha was found beneficial for getting higher growth, fruit yield and alkaloid content by makoi. Among the different fertilizer levels, application of 125:75:75 kg NPK / ha (F8) recorded maximum plant height (74.27 cm), higher number of branches (15.23), higher number of leaves (269.77), fresh and dry yield (16.03 t and 3.71 t/ha, respectively) and higher alkaloid content (0.37 % w/w) and it was followed by F7 (0.34 % w/w) compared to other levels and control.
