ABSTRACT
A field experiment was conducted at Horticulture Research and Extension Centre, Somanahallikaval, Hassan during 2016 to study the effect micronutrient formulationson quality and shelf life of potato cv. KufriJyoti. The experiment was conducted with Randomized Complete Block Design with twelve treatments randomized thrice.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. Micronutrients formulation were sprayed at 30, 45 and 60 DAS.Among those,foliar spray of UHSB-3 micronutrient formulation + RDFrecorded significantly highest dry matter (19.76%), total sugar (0.43%), least rotten tubers (31.62%)compared to control. Delayed tuber rotting (33 days) was recorded by foliar spray of UHSB-1 micronutrient formulation. Further foliar spray of IIHR vegetable special and UHSB-2 micronutrient formulation recorded significantly highest reducing sugars (0.40%), However foliar spray of UHSB-5 micronutrient formulations recorded significantly lowest physiological weight loss (46.25% , 75 days after storage)and least PTM infested tubers (28.40%, 33.65% at 30 and 45 days respectivelyafter storage). Average PTM tunnels per tuber during storage was significantly lowest in foliar spray of IIHR vegetable special at 30 45 and 60 DAS.
Key words: Micronutrients, Solanum tuberosum, Drymatter, Sugars.
