A field experiment was carried out to study the response of foliar application of micro nutrients on the productivity and economic feasibility in bitter gourd during 2010-11, 2011-12 and 2012-13 at the All India Co-ordinated Vegetable Improvement Project in the Regional Horticultural Research and Extension Center, Dharwad. The results based on three years pooled data revealed that, out of nine different treatments, the application of boric acid @100ppm sprayed at 30 and 40 DAS(Days after sowing)resulted in maximum number of fruits per plant (16.48) and fruit weight (91.72g).The same treatment recorded highest fruit yield/plant (15.51 kg) and fruit yield (10.6 t/ha) ,with maximum B:C ratio of (1:1.79). Followed by the next best treatment, mixture of micro-nutrients (Bo + Zn + Mn + Cu + Fe @100ppm and Mo @ 50ppm) recorded fruit yield of (9.89 t/ha) with B:C ratio of (1:1.57) differed significantly from the control.Keywords

The study evaluated the efficacy of various oils and combinations against sucking pests of chilli. The concentration of emulsifier for efficient emulsification of oils was also studied. Detergent powder @ 0.3% effectively emulsified pongamia oil @ 2.5, 5.0 and 10%. Combination of pongamia oil + neem oil + cotton seed oil + citronella oil (50:25:15:10 ratio) @ 2.0% was superior in management of sucking pests followed by pongamia oil + neem oil (50:50 ratio) @ 2.0%. Botanical oils and their combinations had no direct impact on pollinators and natural enemies except citronella oil. Pongamia oil + neem oil + cotton seed oil + citronella oil (50:25:15:10 ratio) and pongamia oil + neem oil (50:50 ratio) yielded significantly higher yield over other treatments.Keywords
