INFLUENCE OF MINERAL FERTILIZER DOZES ON PRODUCTIVITY OF RICE'S PREDECESSORS
Studied two predecessors (winter wheat, alfalfa) and four doses of mineral fertilizers (N110 P50 K70, N140 P80 K100, N77 P35 K49, N98 P56 K70) in three types of rice (Regulus, Flagman, Kubojar). According to studies, Nai best performance on productivity of rice grains-6.79 t/ha achieved class Flagship, the predecessor of alfalfa, at a dose of fertilizers N98 P56 K70 that at 1.81 tonnes/HA higher than the version without fertilizers. In Regulus and Kubojar at the same doses of mineral fertilizers yield was 5.66 and 6.15 t/ha, respectively.
