Impact of bio-fertilizers and fertilizers on potato (Solanum tuberosum L.) cv. Kufri Pukhraj and Kufri Jyoti cultivation

A field experiment was conducted to study the effect of foliar fertilization of zinc and manganese on growth and yield potential of potato at the experimental farm, School of Agriculture, Lovely Professional University, Phagwara during winter season of 2017- 18. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. There were ten treatments used in which one control and remaining treatment consists combination of fertilizer and biofertilizes. Growth parameters were plant height, leaf number while yield parameters were tuber weight, and tuber yield were recorded. Application of different bio-fertilizers alone or in combination with others as seed, soil and foliar spray revealed that the bio-fertilizers have stimulatory effect studied growth parameter of potato. The highest tuber weight and tuber yield with treatment T9 using (T6 + biofertilizer; Azotobactor and phosphate subilizing bacteria). The results showed that the application of different bio fertilizer along with fertilizers revealed significant positive impact on plant height, number of leaves, tuber weight and yield of potato.
