Influence of organic manures, inorganic fertilizers and bio-fertilizers on yield and quality attributes of potato (Solanum tuberosum L.)

Studies on effect of organic, inorganic and bio-fertilizers on yield and quality attributes of potato ( Solanum tuberosum L.) variety Kufri Jyoti, comprising of 10 different treatments using randomized complete block design with three replications were conducted at Post Graduate Centre, University of Horticultural Sciences, Campus, Gandhi Krishi Vignana Kendra, Bangalore during Rabi 2011. Application of 50% RDF + 50% FYM + Azotobacter + Phosphobacteria (T 7 ) showed significantly maximum number of tubers per plant (7.87), tuber yield per plant (363.33 g plant − 1 ) and tuber yield per hectare (34.13 t ha − 1 ). This treatment also produced maximum tuber dry matter (21.67%), starch content (78.20%) non-reducing sugars (0.84%) and total sugars (1.74%) which were on par with T 3 , T 4 and T 6 during rabi 2011.
