Abstract
The present investigation entitled “Effect of Organic Matters on Growth, Yield and Quality of Potato (Solanum tuberosum L.)” was carried out at Seed Production Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, District-Udham Singh Nagar (Uttaranchal) during rabi season of 2002 - 2003. The experiment was laid out in Randomized Block Design with eleven treatments and four replications. The observations on growth characters were recorded at different growth stages, while yield and quality characters were recorded at harvesting. The data were analyzed for standard error of mean and critical difference (C.D.) at 5 % level of significance. Analysis of variance revealed significant differences for all the characters. Based on the findings of the present investigation, T5 treatment (FYM @ 40 t/ha) was found superior over other treatments. Maximum plant emergence, plant height, number of leaves, number of shoots per plant, maximum fresh weight and dry weight of potato tubers per plant, maximum average tuber yield of potato and chlorophyll content of fresh leaves were recorded with high dose of FYM (40 t/ha). But it was found that increasing fertility level with FYM resulted decrease in specific gravity and T.S.S. of fresh potatoes. It was found that higher dose of FYM (40 t/ha) resulted minimum incidence of late blight, aphid population and white fly population per plant.
