Efficiency of application of agronomic ores in cultivation of peas on leached chernozem in the conditions of the Republic of Tatarstan

The effect of phosphorite at a dose of 4 t / ha and glauconite at a dose of 15 t / ha of the Syundyukovskoye deposit and zeolite at a dose of 10 t / ha of the Tatarsko-Shatrashansky deposit on the yield and quality indicators of the seed of peas variety Vatan was studied. In field experiments, the effectiveness of the studied agronomic ores when applied to the soil was revealed. An increase in yield by 8.1-8.9 c/ha and an improvement in grain quality in terms of protein content up to 24.1 %, nitrogen up to 3.66 % and phosphorus up to 0.52 % were established.
