ECONOMIC AND BIOENERGETIC EFFICIENCY OF SAFFLOWER (Carthamus tinctorius L.) CULTIVATION WITH DIFFERENT SOIL PREPARATION TECHNOLOGIES

Abstract

Scientific research for increasing the productivity of new oilseed crops through the development of conservation technology of cultivation was carried out in 2015-2017 on the experimental site of LLP "Fermer 2002" in the Astrakhan district of the Akmola region, which is located in the dry steppe zone of Northern Kazakhstan with a sharp continental climate.The objects of the research were varieties of safflower (Carthamus tinctorius L.) of Kazakhstani breeding - Center 70, Akmai and Irkas cultivated according to the zonal (1 planed tillage of soil in 8- 10 cm +2 planing tillage in 10-12 cm and loosening in 25-27 cm), Minimal I (application of herbicide + 1 planing the soil for 10-12 cm and direct sowing), Minimal II (3 planing tillage in 10-12 cm and direct sowing) and zero (herbicide
application + direct sowing) soil preparation technologies. Based on the results of the research, the positive influence of Minimal 1 soil preparation technologies on the increase in the productivity of safflower varieties was revealed. Among the safflower varieties studied, the variety – Center 70 was characterized by high yield, in which this index was higher than in other varieties by 0,7-2,7 centner/ha. The safflower - Center 70 proved to be economically profitable for the years of the study on a variant with Minimal I soil preparation technology, where the profitability of the Center was 70 – 134,8%, which is higher than the profitability of other options by 3,6 – 45,6%, respectively. The bioenergetic efficiency of cultivation of safflower varieties was also higher on the Minimal I.
