Response of Foliar Application of Micro-nutrients on Yield and Economics of Bitter Gourd (momordica Charantia L.)

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.
