PRODUCTIVITY OF DRY GRASS OF NEW VARIETIES OF ALFALFA DEPENDING ON THE IMPACT OF MACRO-AND MICROCHIPS ON VARIOUS PHOSPHOROUS FUNDS

Abstract

The effect of phosphorus fertilizer on the yield of new alfalfa cultivars Kokorai, Osimtal, and Kokbalausa has been identified after the introduction of P0, P150, and P200(active substance) with nitrogen N60, potassium K70, microele-ments (cobalt (Co), molybdenum (Mo)) on the three noted phosphorus backgrounds. Increasing the dosages of phosphorus increases the yield of the dry mass of the three cultivars. At P0, the dry mass yield of the variety “Kokorai” was 13.2 t/ha, at P150 - 15.9 t/ha and at P200 - 17.3 t/g, the variety “Kokbalausa” was 13.9 t/ha, 16.7 t/ha ha and 17.5 t/ha, also the variety “Osimtal” grade -11.2 t/ha, 14.4 t/ha and 15.7 t/ha. In general, differences in the response of varieties to fertilizers are weak, and they all equally affect fertilizers. However, among the three varieties, the Kokbalausa variety was distinguished by high productivity.
