The application of P30K75 in early spring is recommended in cultivation of meadow clover Tsudowny of the second year of use on improved sod-podzolic light loamy soil with high content of available phosphorus and potassium combinations. It provides green mass yield 788-875 c/ha (of the first year using) and 638-707 c/ha (of the second year using) with well indexes of yield quality. Separate entering P30 has increased in the yield of green mass of meadow clover of the first year of using on 30 c/ha, the second year on 21 c/ha; K75 - accordingly on 42 and 33 c/ha. Consequence of entering into a crop rotation of organic fertilizers promoted additional gathering of green mass in the first year of using of 49 c/ha, in the second year of using - 45 c/ha. The increasing dozes of nitric fertilizers brought under integumentary culture of winter triticosecale, reduced productivity of meadow clover in all years of carrying out of research. The maximal productivity of green mass of 374-453 c/ha of meadow clover of first year of using is received in the first hay crop. In the second hay crop the productivity of green mass has made 298-371 c/ha, in a hay crop of the first year of a life (a zero hay crop) - 64-96 c/ha. Total productivity of green mass of meadow clover of the first year of using has made 739-902 c/ha and on 134-170 c/ha has exceeded the general productivity (605-739 c/ha) green mass of meadow clover of the second year of using. In the second year of using the greatest productivity of green mass of 296-356 c/ha is received in the fourth hay crop; in the fifth hay crop it has made 192-248 c/ha, in the third hay crop - 103-135 c/ha
