The effect of dıfferent norms of potassıum fertılızer on the bıomorphologıcal traıts and productıvıty of table beet (beta vulgaris l. Var. Esculenta)

   The paper discusses biomorphological traits and productivity of the beet plant grown at different norms of potassium fertilizer under the conditions of Absheron. Organic and mineral fertilizers were found to affect positively both the biomorphological traits and productivity of beet. A Bordo-237 variety of beet was used as research material. To calculate the productivity index, the average value of the productivity of one plant was multiplied by the number of plants per hectare. In all variants, biomorphological traits and productivity were higher than those of the non-fertilized (control) variant. The number of leaves and the height of the plant increase with an increasing amount of potassium fertilizer. The indicators of three years were summarized and the mean value was calculated. Depending on the fertilizer norms, the weight characteristics of the above-ground part of the beet plant and the root were studied for years, and the mean value was determined. Besides, depending on the fertilizer norms, the characteristics of the length and diameter of the root vegetable of beet were also studied and evaluated. Studying the effect of potassium fertilizer on the productivity of the beet plant
(average over three years) showed the most productivity in the Background+N120P90K120 fertilizer (998.8 cwt/ha) variant, while the least productivity was observed in the control variant (productivity 528.7 cwt /ha). The reliability of the yield trait was tested using the T-test statistical software. According to all indicators, the results of the Background + N120P90K120 variant were superior and it was found to be the most optimal variant for growing beet under Absheron conditions.
