Abstract
The article presents data on the study of the effect of foliar treatment with the mineral fertilizer «Idrofloral brand 14-11-22+8CaO» and the growth regulator «Stimoros» on the biometric parameters of pear seedlings with a closed root system in protected soil conditions. The research was conducted in 2018-2020 in the Orenburg branch of the Federal Horticultural Research Center for Breeding, Agrotechnology and Nursery. The objects of research were pear varieties of the summer ripening period Lada and Chizhovskaya. The seedlings were obtained by winter inoculation in the third decade of December. The drugs were used three times: 1st processing in the phase of the 5th present sheet, then 2 times with an interval of 10 days. The studied concentrations of non-root top dressing were determined according to the instructions for them. Biometric observations of seedlings were carried out according to the following parameters: seedling height (cm), number (pcs.) and leaf area (cm2 ). Mathematical processing of experimental data was carried out using the dispersion analysis according to B. A. Dospekhov. As a result of the conducted studies, the positive effect of these drugs on the growth and development of pear plants, different depending on the variety, was revealed. The greatest effectiveness on the Chizhovskaya variety was shown by the use of the mineral fertilizer «Idrofloral brand 14-11-22+8CaO» with a rate of application of 3.75 g/l, which contributed to an increase in the length of vegetative growth by an average of 45.6 %, the number of leaves — by 33.7 %, the foliage of seedlings-by 40.0 % compared to the control, thereby having a positive effect on the processes of formation and development of the leaf apparatus. In the Lada variety, the best results were noted when using the drug «Stimoros» at a dosage of 0.94 ml/l: the growth parameters of seedlings increased by 18.4 %, the number of leaves — by 12.1 %.
