Abstract
The field experiments were conducted at farmer’s field Chinchali village, Rayabag taluka, Belagavi District, Karnataka during kharif 2014-15 and 2015-16 and laboratory experiment were conducted in Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad during 2014-15. The results revealed that, retaining all fruits for seed purpose recorded significantly higher seed yield (369 kg/ha) as compared to plucking initial formed 18 fruits of green stage for vegetable purpose and retaining remaining fruits for seed purpose.
For seed production of brinjal, plucking initial formed 3 fruits of green stage for vegetable purpose and retaining remaining fruits for seed purpose compared to retaining all fruits for seed purpose was found to be most ideal as it registered on par test weight, number of seeds per fruit, seed yield with better quality parameters and an extra income of Rs. 14,395 per hectare was obtained.
Among the foliar spray with insecticides, emamectin benzoate was most effective in suppressing the pest population as lowest mean per cent fruit infestation and seed damage was recorded after its application (15.50 and 12.33 % respectively) followed by flubandamide (16.71 and 13.09 %) and spinosad (18.17 and 14.93 %).
Brinjal seeds primed with GA3 50 ppm and PEG @ 1.25 MPa and drying them back to their original moisture content needs to be practiced to obtain higher seed quality.
The optimum yield with better quality seed can be obtained from the brinjal cv. Kudachi local when 35 days old seedlings were transplanted with GA3 @ 50 ppm growth regulator spray.
