Economic and bioenergetic evaluation of sunflower variety and hybrid cultivation

Economic and bioenergetic evaluation of sunflower variety and hybrid cultivation. Tishkov N.M., V.I. Veter. "Scientific Bulletin", VNIIMK, 2005, v. 1 (132). Estimation of economic and bioenergetic efficiency of seed sowing norms and application of fertilizers in cultivation of sunflower varieties (SUR, Master). and hybrids (Kubanskiy 930 and Kubanskiy 931). of VNIIMK breeding in 1999-2001 are presented. The most profitable cultivation of studying sunflower varieties and hybrids is determined with local applying of N20P30 when sowing with optimal plant population to harvest: 60-70 th/ha - for SUR, and 40-50 th/ha - for Master, Kubanskiy 930 and Kubanskiy 931.
