Influence of foliar supplementation of zinc and manganese on yield and quality of potato, Solanum tuberosum L

An investigation on influence of foliar supplementation of zinc and manganese on yield and quality of potato was carried out in factorial randomized block design with three replications during Rabi 2012 at SD Agricultural University, Sardarkrushinagar. Total sixteen treatments comprised foliar application of Zn (0, 5, 10 and 15 ppm) and Mn (0, 2, 4 and 6 ppm). Results of present investigation revealed that the main effect of Zn 15 ppm and Mn 6 ppm was significantly superior with respect to various yield and quality attributes. Significantly highest tuber yield per plant (610. 43 g), tuber yield per hectare (417.61 q) and quality parameters viz reducing sugar (3.53%), non-reducing sugar (4.33%), total sugars (7.86%) and protein (2.60%) were recorded under the supplementation of Zn 15 ppm and Mn 6 ppm (Z₃ M₃).
