PROSPECTIVITY OF CULTIVATION OF NEW PUMPKIN CROPS IN THE LOWLAND ZONE OF TRANSCARPATHIA WITH DIFFERENT METHODS OF GROWING
The aim of the research. To establish the efficiency of using different elements of the technology of growing uncommon pumpkin crops momordica and kiwano on their vegetation and yield in soil and climatic conditions of the lowland zone of Transcarpathia. Methods. Phenological observations, biometric measurements, statistical methods. Results. It was found that more early-maturing, with a longer period of fruiting, and accordingly a longer period of vegetation were momordica plants grown using as waste fertilizers coffee production. Thus, in the flowering phase of the experiment plants entered 7 days earlier, in fruiting – 5 days. Variants differed in plant height: 2.85 m when using coffee waste against 2.17 m in the control. The average weight of the fruit in the phase of technical maturity was 218 g in the variant with the use of coffee and 127 g in the control; average fruit length – 24.1 and 14.5 cm; the number of fruits formed by the plant increased by 3 pcs. compared to control; in one fruit in the control was formed by 11 seeds less. On average, from one plant when using coffee waste, received almost 2.2 times more yields than in the control. Phenological observations of kiwano plants allowed to establish a significant difference (6 days) only in the duration of the interphase period "beginning of branching – beginning of flowering" with the use of growth stimulant sodium humate. The difference in the duration of other interphase periods ranged from 1 to 3 days. At the initial stages of growth in the third decade of June, the experimental plants prevailed over the control over the number of leaves of one plant, the assimilation surface area of the experimental plants – by 20%, and the stem height – by 4%. At the beginning of the first decade of August, both variants began to form fruits. The average weight of one fruit in the experiment was 232.6 g, the diameter ranged from 6.9 to 13.3 cm, length – 8.7–15.7 cm. In control plants, the fruit weight averaged 173.1 g, the diameter was in the range of 6.3–9.2 cm, length – 7.2–13.7 cm. The number of fruits per plant of the experiment by 15% exceeded the control, their weight – by 34%. The total yield of kiwano reached 4.7 kg/m2 in experimental plants, which is 1.6 times more than the control (3.0 kg/m2). Conclusions. Studies show the effectiveness of the use in the cultivation of momordica as a fertilizer for coffee waste and the positive effect of pre-sowing treatment of kiwano seeds with sodium humate.
