Maximal productivity of spring triticosecale grain of Kargo and Lana varieties was formed at an earlier sowing term when soil achieved its physical ripeness. In average for 2002-2004 years at Kargo it has made 51,0 c/ha, at Lana - 49,1 c/ha. Sowing through 5 days after early term has decreased the grain productivity in average daily on 44-54 kg, in 10 days - on 60-68 and 15 days - 62-71 kg. Kargo variety was more productive than Lana and weaker reacted to sowing term. Delay with sowing terms influenced negatively on the biometric parameters of plants and yield structure. Protein content in triticosexale grain comparatively weak and nonresistance changed in dependence on sowing terms. But the protein collection of grain from hectare at sowing delay decreased. The certain interest represents relative late ripeness of spring triticosecale. At optimum early terms of sowing it ripens for 7-10 days after others spring cereals. It enables to reduce intensity of harvest works and to reduce losses of yield which make at перестое breads for a week in August of 1,2 c/ha, in September - 1,9 c/ha. Carried out researches on comparative efficiency have shown, that on productivity of grain it considerably exceeds spring wheat, barley and oats
