Abstract
The aim of the research. To determine the influence of plant growth regulators on the basis of humic acids and complex microfertilizers on the yield of fruits and seeds of parthenocarpic cucumber Lyric F1 in greenhouses conditions and to determine the indicators of their economic efficiency. Methods. Field, statistical. Results. It was established that the use of plant growth regulators: Hydrogumin, Gulliver Stimul, Vimpel Maxi and microfertilizer CompleMet positively affects the formation of productive and generative organs. Thus, the yield of fruits with the use of 3-times extra-root spraying of PGR and microfertilizer plants increased by 1.06–2.48 kg / m2. The average gain to control (13.22 kg / m2) at the expense of the application of PGR was 8.00–18.71%. The highest yield of cucumbers was noted in the variant with the use of microfertilizer СompleMet – 15.70 kg / m2. It was established that treatment of the maternal form of the cucumber h ybrid Lyric F1 with Hydrogumin and CompleMet does not result in an increase in the number of seeds per plant. However, the yield of seed from one seedling in variants using PGR Hydrohumin and microfertilizer CompleMet, due to their increase in the number and weight of 1000, was higher and was 2.64 and 2.26 g, respectively, with 2.2 g in the control. The yield of seeds in variants with the use of drugs Hydrogumin and CompleMet was 142.2 g / m2 and 135.6 g / m2 respectively at 97.44 g / m2 in the control. The proposed method of increasing the yield of cucumber seeds in greenhouses conditions can increase the profitability of seed production by 10–25 %. The highest profitability ratio of 72% ensures the application of microfertilizer CompleMet at 47% under the basic cultivation technology. Conclusions. The results of the research indicate a positive effect of using PGR and microfertilizers to increase the yield of cucumber at 8.00–18.71 % and 39–46 % respectively. The highest yield of cucumber fruit is noted when applying microfertilizer ComplemeMet – 15.70 kg / m2, seed yield – when using PGR Hydrohumіn - 142.2 g / m2. The expediency of the use of drugs for increasing the productivity of fruits and seeds of cucumber on a number of economic indicators has been proved. The cost-effectiveness of microfertilizer CompleMet in the technology of growing cucumber fruits in greenhouses conditions is 72%, PGR Hydrogumin for hybrid seed production is 167%, respectively.
