Представлены материалы экспериментальных исследований по разработке элементов технологии возделывания столовой свеклы на луговых среднесуглинистых почвах сухостепной равнинной зоны Дагестана. Цель исследований – повышение урожайности свеклы столовой на основе выбора оптимальной схемы и густоты посева свеклы сорта Бордо 237, а также применения регулятора роста Биостим Универсал с использованием системы капельного орошения. Фактор А – схемы посева с двумя вариантами: А1 – широкорядный посев с междурядьем 45 см (контроль) и А2 – двустрочный ленточный посев по схеме 20+50. Фактор В – густота посевов с тремя вариантами: В1 – расстояние в ряду через 6 см, В2 – через 8 см и В3 – через 10 см соответственно, что в зависимости от схемы посева обеспечивало густоту посева столовой свеклы от 222 до 473 тыс. шт/га. Фактор С – обработка растений с двумя вариантами: С1 – опрыскивание водой (контроль) и С2 – некорневая подкормка биостимулятором-антистрессантом Биостим Универсал (в фазе 4–6 листа) и при 50%-ном смыкании рядков (в фазе 8–10 листа). Доза применения препарата – 2,0 л/га с расходом рабочего раствора 200–400 л/га. Система капельного орошения состояла из поливных трубопроводов с расстоянием между ними 0,7 м, между капельницами – 0,3 м с расходом воды 2 л/ч. Средний срок посева – первая декада апреля. Поддержание необходимого режима орошения свеклы столовой обеспечивали вегетационными поливами с нормой 125 м3/га при оросительной норме 2875 м3/га. Выявлено, что наиболее оптимальная схема посева столовой свеклы: двустрочный ленточный посев – 20+50 см с расстоянием в ряду через 8 см, которая при двукратной некорневой подкормке препаратом Биостим Универсал в дозе 2,0 л/га с расходом рабочего раствора 200–400 л/га обеспечивает урожайность 59,8 т/га корнеплодов при их высоком качестве. The materials of experimental studies on the development of elements of the technology of cultivation of table beets on meadow medium loamy soils of the dry-steppe plain zone of Dagestan are presented. The purpose of the research is to increase the yield of table beet based on the selection of the optimal scheme and the density of sowing of Bordo 237 beet, as well as the use of a Biostimulator growth regulator using a drip irrigation system. Factor A is a seeding scheme with two options: A1 is a wide-row seeding with a row spacing of 45 cm (control) and A2 is a two-line ribbon seeding according to the scheme 20+50. Factor B is the density of crops with three options: B1 – the distance in a row after 6 cm, B2 – after 8 cm and B3 – after 10 cm, respectively, which, depending on the sowing scheme, provided the density of table beet sowing from 222 to 473 thousand pcs/ha. Factor C – treatment of plants with two options: C1 – spraying with water, control and C2 – foliar feeding with biostimulator-antistressant Biostim Universal (in the phase of 4–6 leaves) and with 50% closure of rows (in the phase of 8–10 leaves). The dose of the biostimulator is 2.0 l/ha with a working solution consumption of 200–400 l/ha. The drip irrigation system consisted of irrigation pipelines with a distance of 0.7 m between them, 0.3 m between droppers with a water flow rate of 2 l/h. The average sowing period is 1 decade of April. Maintenance of the necessary irrigation regime of the canteen beet was provided by vegetation irrigation with a rate of 125 m3/ha with an irrigation rate of 2875 m3/ha. It was revealed that the most optimal scheme for sowing table beets: two-line ribbon sowing – 20+50 cm with a distance in a row through 8 cm, which, with two-fold foliar top dressing with a Biostim Universal at a dose of 2.0 l/ha with a working solution consumption of 200–400 l/ha, provides a yield of 59.8 t/ha of root crops with their high quality.

This article deals with the issue of solar-powered irrigation, specifically, by connecting a solar power source to a drip irrigation system. Thanks to an independent energy source the irrigation system is able to work anywhere. In addition to energy independence, thanks to the drip mode of irrigation, another benefit is water saving, which is up to 70% compared to conventional irrigation. The simplicity of this system allows use both in small gardens and in agriculture. Another advantage of the system is its expandability with various sensors (e.g. soil moisture monitoring), which will help with more efficient management of watering.

Water plays the important roles for plants. Besides maintaining the cell turgidity, it also functions as a nutrients solvent for photosythesis process, which affects plant growth. This study aimed to determine the effects of the source and volume of irrigation water with drip irrigation system on the growth of pepper plants in polybags. This research was conducted at the green house of Polbangtan Manokwari, Anday, West Papua from June to October 2020. This research was arranged in a factorial Completely Randomized Design consisting of two treatment factors, namely irrigation water source (PDAM water and ground water) and volume (150 mL per plant, 200 mL per plant, and 250 mL per plant). The results showed that PDAM water showed a better effect than groundwater, while the volume of irrigation water applied to pepper plants had no significant effect on plant height, number of leaves, and stem diameter. This situation is thought to be due to genetic factors from the pepper cultivars grown. PDAM water has a better effect because of its high pH and higher content of Nitrite as N content. Also, it has lower temperature, lower TDS, and lower iron contents. Meanwhile, irrigation water volume of 250 mL per plant per day has a minimal risk of plant drought compared to other treatments.
