Response of Sugar Beet to Graded Levels of Nitrogen, Phosphorous and Potash on Nutrient Uptake and Economics

Field experiment was undertaken during 2005-06 to 2006-07 to study the various agro-techniques for sugar beet cultivation for Northern Karnataka at Agricultural Research Station, Bailhongal, Belgaum district (Karnataka) under irrigated condition. The experiment consisted of 28 treatment combinations comprising of graded levels of nitrogen, phosphorus and potassium. Design of the experiment was randamized block design with factorial concept. Application of 180, 90 and 120 kg ha-1 of nitrogen, phosphorus and potassium, respectively registered significantly higher nitrogen, phosphorus and potassium uptake by sugar beet compared to other levels of nutrient. The same dose of nutrient application also improved gross returns and net returns. Farmers can adopt application of 180, 90 and 120 kg ha-1 of nitrogen, phosphorus and potassium, respectively for getting higher yield and quality of the crop.
