EFFECT OF SPACING AND NPK ON GROWTH AND YIELD OF MAKOI (SOLANUM NIGRUM L.) UNDER HILL ZONE OF KARNATAKA, INDIANagaraj Gokavi, M. Ravikumar, Chandalinga and T. ChethanAbstract An investigation was carried out to study the effect of spacing and NPK on growth and yield of makoi 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, spacing of 60 x 45 cm and application of NPK fertilizer @ 125:75:75 kg /ha was found beneficial for getting higher growth and fruit yield by makoi. Among different spacing levels, maximum plant height (70.41 cm) was noticed in S1 (60 x 45 cm) and the spacing of 60 x 60 cm (S2) recorded maximum number of branches (14.22) and maximum number of leaves (233.77), higher fresh and dry fruit yield (14.33 and 2.58 t/ha, respectively). 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) by makoi compared to other levels and control. Non-significant difference was noticed among the interaction with respect to number of leaves. Whereas, maximum plant height (76.00 cm) was noticed in the plants spaced at 60 x 45 cm and supplied with 125:75:75 kg NPK / ha (S1F8). While, maximum number of branches (15.43) was noticed in the plants spaced at 60 x 60 cm and supplied with 125:75:75 kg NPK / ha (S2F8) combination. The interaction of spacing and fertilizer levels showed non significant effect in increasing fresh and dry yield of makoi.
