A field experiment was conducted under All India Co-ordinated Research Project on Potato at Horticulture Research and Extension Centre (HREC), Hassan, Karnataka consecutively for three years during Kharif season of 2015, 2016 and 2017 to study the effect of foliar application of micro-nutrient formulation on growth, yield and benefit cost ratio in potato Cv Kufri Jyoti. An experiment was laid out in Randomized Complete Block Design with four replications by adopting standard spacing of 60 cm x 20 cm. In each formulation different concentration of micro-nutrients were used. The micro-nutrients and their formulation were sprayed at 30, 45 and 60 days after planting of tubers. Among the different formulations, foliar spray of UHSB-3 potato specific micro-nutrient formulation along with recommended dose of fertilizers recorded significantly highest A grade (>75g) tubers (11.78 t/ha), B grade (51-75 g) tubers (4.54 t/ha), C grade (26-50 g) tubers (3.06 t/ha), total tuber yield (21.07 t/ha) and B:C ratio of 2.22. Therefore it was indicated that in all the three years, foliar spray of UHSB-3 potato specific micro-nutrient formulation along with recommended dose of fertilizers influenced progressively in terms of producing highest tuber yield and net returns.
