The yield of Brussels cabbage depending on the weather conditions of the growing season, the layout of the placement and the terms of the maintenance of plants

Abstract

The researches were aimed at a scientific substantiation of the influence of the weather conditions of the growing season of Brussels cabbage, the scheme of placement of plants, the terms of recipe for yield. Methods. Field, physico-chemical, calculation, analysis. Results The conditions of the growing season influenced the production of cabbage in Brussels. The equations of the regression dependence of the cabbage productivity of Brussels on the weather conditions of the vegetation period are developed It has been established that the productivity of a single Brusselsian cabbage plant depends on the density of plants. The largest (0,8 kg) she was with a density of 35,7 thousand pcs / ha, less (0,5 kg) – at a density of 47,6 thousand pcs/ha Depending on the terms of creaming, this indicator decreased to a great extent at a later date, from 0,7 to 0,2 g. All this was reflected in the level of yield of the heads in the corresponding variants. The yield of Brussels sprouts depends on the number of cabbage and average weight. The number of heads varies from 60 pcs. Diamond F1 up to 66 pcs. Abacus F1. But the average weight of the hybrid head Diamond F1 exceeded the average weight of the Abacus F1 head 2,5 times, which significantly affected the total yield of cabbage. Conclusions Increase in productivity was established – by 0,6 t / ha with a thickening from 28,6 to 35,7 ths. pcs / ha Further consolidation to 47,6 ths. pcs / ha resulted in a decrease in the yield level by 1,1 t / ha compared with a density of 28,6 ths. pcs / ha Consider the third decade of August as the optimum time for treating Brussels cabbage. Late with creaming reduced yields by 3,1 t / ha, and the total refusal of this admission was 4,7 t / ha with LSD 05 = 0,91 t / ha. The yield of Brussels sprouts is closely related to the weight of the head: r = 0,72 ± 0,03 ... 0,77 ± 0,03 depending on the hybrid. The number of heads on the plant had a strong correlation with the yield of the hybrid Abakus F1: r = 0.85 ± 0,02, in the diamond F1 – weak.
