Studies on influence of specific micronutrient formulation on grade wise tuber yield and quality in potato (Solanum tuberosum L.)

Abstract

A field experiment was conducted at Horticulture Research and Extension Centre (HREC), Somanahallikaval, Hassan during 2016 to study the effect different micronutrients and their formulation on growth, yield and quality of potato (Solanum tuberosum L.) Cv Kufri Jyoti. The experiment was conducted with Randomized Complete Block Design with twelve treatments and three replication. In each formulation different concentration of micronutrients were used. The micronutrients and their formulation were sprayed at 30, 45 and 60 days after sprouting of tubers. Among the different formulations, foliar spray of UHSB-3 micronutrient formulation along with RDF recorded significantly highest A grade (>75g) tuber yield per plant (532.15 g), total yield per plant (687.87 g), A grade tuber yield per hectare (16.65 t/ha), total tuber yield per ha (25.18 t/ha), dry matter content (19.76%) and total sugar (0.43%).
