Важный критерий оценки гибрида или сорта, определяющий его конкурентоспособность, – экономическая эффективность выращивания в условиях товарного производства. Цель исследований – определить экономическую эффективность выращивания перспективного гибрида перца сладкого F1Тибет (селекция ФГБНУ «ФНЦ риса») в товарном овощеводстве по интенсивной технологии. Производственные испытания проводили в 2019–2020 годах в ООО «Агро-Союз» Крымского района Краснодарского края. Рассаду выращивали в пленочной теплице с обогревом. Высадку рассады на гряды проводили с 5 мая механизированно с одновременной укладкой капельной ленты и мульчирующей биоразлагаемой пленки. Схема посадки ленточная – 90+50/2×30 см. Количество растений на 1 га – 50 тыс. шт. Система минерального питания включала основное внесение комплексного удобрения – 700 кг/га азофоски и регулярных подкормок, в зависимости от фазы развития. В подкормки на 1 га за период вегетации вносили: кальциевую селитру – 300 кг, карбамид – 200 кг, аммиачную селитру – 200 кг, нитрат калия – 100 кг, сульфат калия – 100 кг, ортофосфат калия – 50 кг, ортофосфорную кислоту – 50 л. Система защиты от бактериальных болезней включала еженедельную обработку (до восьми раз за сезон) биофунгицидами: Фитолавином (0,5 л/га), Фитоспорином М (1 л/га) и Витопланом (0,1 кг/га). Полив проводили 1–2 раза в неделю согласно показаниям тензиометров, установленных на глубину 15 и 30 см. Убирали красные плоды два раза за сезон, в октябре получали дополнительный урожай зеленых плодов. Производственные испытания показали, что гибрид F1 Тибет раннего срока созревания создан для товарного производства и отвечает требованиям перерабатывающей промышленности. Гибрид показал высокий уровень рентабельности (89,5–106,3%) при сборе урожая в биологической спелости плодов. Результаты производственных испытаний также продемонстрировали высокую экономическую эффективность и востребованность гибрида и его аналогов в товарном овощеводстве по приемлемой цене гибридных семян (7,0–7,6% от общих затрат). An important criterion for evaluating a hybrid or variety that determines its competitiveness is the economic efficiency of cultivation in commercial production. The purpose of the research is to determine the economic efficiency of growing a promising hybrid of sweet pepper F1 Tibet (selection of FSBSI «Federal Rice Center») in commodity vegetable growing by intensive technology. Farm tests were carried out in 2019–2020 at Agro-Soyuz LLC in the Crimean district of Krasnodar region. Seedlings were grown in a film greenhouse with heating. Seeds were sown in cassettes No96 in the first decade of March. The planting of seedlings on the ridges was carried out mechanized with simultaneous laying of drip tape and mulching biodegradable film was carried out from May 5. The planting scheme is ribbon – 90+50/2×30 cm. The number of plants per 1 ha is 50 thousand units. The mineral nutrition system included the main application of complex fertilizer – 700 kg/ha of azofoska and regular top dressing, depending on the phase of development. During the growing season, calcium nitrate – 300 kg, carbamide – 200 kg, ammonium nitrate – 200 kg, potassium nitrate – 100 kg, potassium sulfate – 100 kg, potassium orthophosphate – 50 kg, orthophosphoric acid – 50 litre were added to the top dressing per 1 ha. The system of protection against bacterial diseases included weekly treatment (up to eight times per season) with biofungicides: Phytolavin (0.5 l/ha), Phytosporin M (1 l/ha) and Vitoplan (0.1 kg/ha). Watering was carried out 1–2 times a week, according to the indications of tensiometers installed at a depth of 15 and 30 cm. Red fruits were harvested twice a season, in October they received an additional harvest of green fruits. Farm tests have shown that the F1 Tibet hybrid of the early ripening period is created for commercial production and meets the requirements of the processing industry. The hybrid showed a high level of profitability (89.5–106.3%) when harvesting in biological ripeness of fruits. The results of farm tests also demonstrated the high economic efficiency and demand for hybrid and its analogues in commercial vegetable growing at an affordable price of hybrid seeds (7.0–7.6% of total costs).

Fresh pollen of 16 promising genotypes of gladiolus was tested for their pollen viability. Modified cellophane method was employed to assess the pollen viability. Pollen germination media consisted of 15% sucrose supplemented with 300 ppm calcium nitrate, 200 ppm magnesium sulphate, 100 ppm potassium nitrate and 100 ppm boric acid. Highly significant variations were observed for percentage of pollen germination, non-germinated pollen and sterile pollen. The highest pollen germination (76.41%) was in genotype Hybrid selection 88-10-22, and did not differ significantly from Gladiolus callianthus (75.41%), Sapna (75.10 %), Hybrid selection 86-32-11, (73.28 %), Kum Kum (69.41%), Poonam (69.22 %), Hybrid selection 87-22-1 (67.87 %), Hybrid selection 87-1-1 (67.61 %), Psittacinus hybrid (64.64%) and Darshan (63.97%). The lowest non- germinated pollen (10.47%) was in genotype Gladiolus callianthus, and insignificantly followed by Hybrid selection 88-10-22 with 18.77 % and Hybrid selection 87-22-1 with 18.95 %. The lowest percentage of sterile pollen was noticed in genotype Sapna (2.82%) followed by Poonam with 4.00 % Hybrid selection 88-10-22 with 4.82% and Hybrid selection 82-11-27 with 5.22%.

Columnar apple cultivars are optimally suited to lay apple tree plantings using intensive technology, which provides for super-dense placement of trees. The article considers a variant of growing columnar apple cultivars on inserts of dwarf rootstocks 3-17-38 and 62-396. The use of dwarf rootstocks 3-17-38 and 62-396 as intercalar inserts in the cultivation of columnar apple cultivars, along with good anchoring of plants, provides high precocity, productivity and economic efficiency of planting. All the costs of laying the orchard and annual works on agrotechnical care of the trees were paid off in the fourth year after planting.The economic and biological features of the columnar cultivars provided not only a quick return of the investments, but also a high level of profitability. The profitability of the studied columnar planting for the 6th year after planting (2020) on average for all cultivars was 106.0 % on the insert of the dwarf rootstock 62-396 and 104.7 % on the insert 3-17-38. The profit received on average for the plantings amounted to 2 378 661 rubles per ha. In the group of the studied cultivars, there is a difference in economic efficiency. The lowest level of productivity and profitability was in the Vostorg cultivar: on average, on two inserts, the yield in 2020 was 27.3 t/ha and the profitability was 66.6%. The Girlyanda cultivar was characterized by the maximum yield and profitability: 88.0 t/ha and 115.8%, respectively.

Blockchain and smart contracts are forming new systems to record and manage businesses with less need for intermediaries. The new systems are expected to offer high level of governance with lower cost as compared to the traditional technologies. While there is a continuous effort to apply this innovative technology in several businesses, Islamic finance in general—and Islamic social finance in particular—are facing few challenges that could be solved by such innovations. Islamic social finance institutions such as waqf are facing some challenges in enhancing its governance structure to ensure Shariah compliance as well as economic efficiency. This chapter explains how blockchain and smart contract technologies can help these institutions for better governance, lower transaction cost, more transparency, and higher trust, hence enhancing the business flexibility and market accessibility. It also presents some related cases that are currently under development as an evidence for the practicality of these technologies in the Islamic social finance arena.

The production of lettuce in hydroponic systems with a recirculating nutrient solution has been growing, so it is necessary to evaluate the growth and quality of production under this system. Two harvest cycles were evaluated, comparing the behavior of physiological variables and growth rates on lettuce plants in a hydroponic system with a plastic cover. Lettuce plants were planted at 30 days after germination in an NFT hydroponic system. Nutrient solutions were prepared with sources of potassium nitrate, calcium nitrate, urea phosphate, magnesium sulfate and a source of minor nutrifeed. The second cycle had the highest total dry mass and leaf area index (LAI) at 43 days after transplant (dat). The relative growth rate (RGR) declined over time. The absolute growth rate (AGR) presented a sigmoid behavior as a gaussian bell shape; the leaf area index (LAI) increased until 43 dat, with the second cycle presenting the highest value; the net assimilation rate (NAR) decreased over time, with the second cycle having the highest value at 22 dat. The chlorophyll content for this variety was low, with a yellow pigmentation in the plant. The stomatal conductance (SC) in the two cycles at transplant time presented low values caused by the stress leaded by an imbalance in the pH of the solution, when the plants adapted to the system, this value increased.
