Sunflower variety and hybrid reactions on the mineral nutrition levels and acidity of leached chernozem

Sunflower variety and hybrid reactions on the mineral nutrition levels and acidity of leached chernozem. Tishkov N.M., Mikhailyuchenko N.G., V.I. Veter. "Scientific Bulletin", VNIIMK, 2005, v. 1 (132). Results of 1998-2000 researches of vegetation trials in conditions of greenhouse for detection of reaction of sunflower varieties and hybrids of VNIIMK breeding on mineral supply level and acidity of leached chernozem are presented. Specificity of dry mass formation, yield elements and seed productivity, correlation of separate plant parts in common biomass by studying varieties (SUR, Master)., three-ways hybrids (Kubanskiy 939, Kubanskiy 930, Kubanskiy 931, Kubanskiy 937, Kubanskiy 480, Kubanskiy 941). and their maternal forms (CMS Kubanskiy 48 and CMS Kubanskiy 93). depended on nutrition element content in the soil and its acidity is established.
