В 2017–2019 годах изучены сортообразцы сладкого картофеля на староорошаемых лугово-сероземных почвах Зарафшанской долины. Цель исследований – комплексная оценка сортообразцов батата в условиях Зарафшанской долины по скороспелости, росту, развитию, интенсивному размножению, формированию урожая, компактности клубней в гнезде, продуктивности, урожайности и лежкости клубней и выделение из них перспективных, а также разработка приемов агротехнологии получения высоких урожаев для данных условий. Почвы опытного участка характеризуются благоприятными агрофизическими и водными свойствами и низким содержанием гумуса, нитратного азота, подвижного фосфора и содержанием обменного калия от низкого до среднего. Сравнивали 18 сортообразцов батата. Выделенные сортообразцы изучали при ширине междурядий 70 и 90 см со схемой 70×25 и 90×20 см по 1, 2 и 3 растения в гнезде. Для получения рассады сортообразцов батата брали по 40 клубней и высаживали 20–22 февраля в пленочной теплице при температуре 15–18 °C, заделывая их на глубину 3–5 см. Влажность почвы поддерживали на уровне 65–70%. Через 7–10 дней после высадки почки начинают прорастать, а через 43–48 дней формируется рассада высотой 12–15 см, готовая для высадки в поле. Высадка рассады, как и других рассадных культур (томата, перца, баклажана) – по схеме 70×20–25 см во второй-третьей декаде апреля. Уход включал в себя междурядную обработку (культивация), прополку, борьбу с сорняками, подкормку, поливы. Уборка урожая – в конце сентября-начале октября с помощью картофелекопателя. В результате исследований выделились сорта по скороспелости, дружности формирования ростков, ускоренному размножению, продуктивности, компактности клубней в гнезде и с высоким товарным урожаем – Сочакинур, Хар-Бей и Япон. Возделывание этих сортообразцов по схеме 70×25 и 90×20 см способствует получению товарного урожая высокого качества не менее 43–48 т/га. In 2017–2019, studies were conducted on the study of varieties of sweet potatoes on old-irrigated meadow-gray-earth soils of the Zarafshan valley. The purpose of the research is a comprehensive assessment of sweet potato varieties in the conditions of the Zarafshan valley in terms of early maturity, growth, development, intensive reproduction, yield formation, compactness of tubers in the nest, productivity, yield and keeping quality of tubers and the selection of promising ones, as well as the development of methods of agricultural technology for obtaining high yields for given conditions. The soil is characterized by favorable agrophysical and water properties and low content of humus, nitrate nitrogen, mobile phosphorus and a low-average content of exchange potassium. Eighteen sweet potato varieties were compared. The selected variety samples were studied with a row spacing of 70 and 90 cm with a scheme of 70×25 and 90×20 cm for 1, 2 and 3 seedlings in the nest. To obtain seedlings of sweet potato varieties, 40 tubers were taken and planted on February 20–22 in a film greenhouse at a temperature of 15–18 °C, seeding to a depth of 3–5 cm, the soil moisture was maintained at 65–70%. 7–10 days after planting, the buds began to germinate, and after 43–48 days, seedlings were formed with a height of 12–15 cm, which is ready for planting in the field. Planting seedlings in the field is carried out, as well as other seedlings (tomato, pepper, eggplant) according to the scheme 70x20–25 cm in the second or third decade of April. Growing includes inter-row processing (cultivation), weeding, weed control, top dressing, watering. Harvesting in late September, early October with a potato digger. As a result of the research, varieties were identified in terms of early maturity, sprout formation, accelerated reproduction, productivity, compactness of tubers in the nest and ensuring a high marketable yield – Sochakinur, Xar-Bey, and Japon. The cultivation of these varieties according to the scheme 70×25 and 90×20 cm contributes to the production of a commodity crop at 43–48 t/ha with good qualities.

The effect of applying various norms of mineral fertilizers on the biological indicators of crop plants during their growth and development in the Central non-black earth region in 2017-2019 was studied on the varieties of spring barley Vladimir, Reliable and Yaromir.such indicators as plant height, photosynthetic apparatus area, green mass growth, and elements of the yield structure were Studied. It was revealed that on average during the growing season, when the norms of mineral fertilizers were increased, the area of leaf plates increased and, as a result, the increase in green mass growth relative to the control variants increased by 56.3 % at (NРК)30, 82.3 % at (NРК)60, and 126.7 % at (NРК)90. The introduction of mineral fertilizers also influenced the formation of the crop structure. There was an increase in the tillering coefficient of varieties by 15.7%, 5.7 % and 21.3 % (Vladimir, Reliable and Yaromir, respectively) relative to the control, an increase in the number of grains in the ear from 15.1 to 22.4 PCs., the weight of 1000 grains from 48.0 to 55.7 g. and the weight of grain per ear from 0.7 to 1.2 g. There was a strong correlation between the doses of mineral fertilizers and the grain yield from + 0.80 to +1.0, and the variability was calculated.
