Abstract
Application of sulfur fertilizers at the doses of 15 and 30 kg/ha (with NPK) for irrigated potatoes on chestnut soils of Western Transbaikalia is the most effective for production of marketable tubers with the maximum value of bioenergy coefficient. With increasing the doses of sulfur, in spite of the insignificant increase of crude protein content, the amount of amino acids and the index of essential acids significantly increased in comparison with the control and the background. Replacement of limiting sulfur-containing amino acids (methionine + cystine) with leucine was noted. The highest biological value of potato protein at the level of 72–74% was found at the doses of 15 and 30 S kg/ha (with NPK).
