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. KufriJyoti. The experiment was conducted with Randomized Complete Block Design with twelve treatments and three replication. Treatments included were T1 (control)- RDF (FYM 25 t/ha + N:P:K at 75:75:100 kg/ha), T2: T1+ boron, T3: T1+ zinc, T4: T1 + zinc + boron, T5: T1 + IIHR vegetable special, T6: T1 + IIHR potato special, T7: T1 + UHSB 1, T8: T1 + UHSB 2, T9: T1 + UHSB 3, T10: T1 + UHSB 4, T11: T1 + UHSB 5, and T12: RDF of N:P:K without FYM. 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, T11-foliar spray of UHSB-5 micronutrient formulation along with RDF recorded the maximum plant height (66.87 cm) whereas, T9-foliar spray of UHSB-3 micronutrient formulation along with RDF recorded significantly highest number of branches per plant (4.60), number of compound leaves per plant (24.67) and plant canopy spread (1612.64 cm2) at 60 days after sprouting of tubers. Same treatment was also recorded significantly highest tubers per plant (7.87), tuber weight per plant (687.87 g/plant), tuber yield per hectare (25.18 t/ha) and dry matter content (19.76%).
