Comparative Analysis of the Effectiveness of Organic and Inorganic Nitrogen Sources on Potato Yield and Soil Fertility

Potato is a vital food source for the high hills of Nepal. The crop requires right amount nutrient at appropriate time optimal growth and production. However, low availability, cost, inappropriate timing applying nitrogenous fertilizers like urea have made it challenging farmers to use correct in their fields. Therefore, affordable renewable sources plant nutrients should be used supplement chemical fertilizers. In addition this, using organic can improve soil properties. To determine effects nitrogen supplied through different sources, an experiment was conducted randomized block design. There were eight treatments, each with combination various as N1(100% rec N via Urea), N2 (50 % FYM + 50 N3 PM N4(50 GM Urea) , N5 (75 25 N6 N7 N8 (Farmer practices (FYM 10 t ha-1)). yield potato tubers significantly higher when recommended applied 50% manure poultry, FYM, goat, than other including farmer practice ha-1 FYM. statistically par sole urea.
