В статье представлены основные агрохимические исследования, проводимые на темно-серых почвах опытного поля Ленкоранско-Астаринском региона. Результаты анализа агрохимических показателей почвы исследуемого участка показали, что pH в пробах почвы имеет слабую кислотность, колеблется в пределах 6,12-5,87 на глубине 0-30 см и на глубине 30-60 см - в пределах 5,98-6,20. Исследованные почвы не содержат карбонатов, плодородны, количество гумуса в пахотном слое в среднем варьируется от 3,03-3,14 % (3,045-3,157), на глубине 30-60 см 1,63-1,73 % (1,618-1,751), и на глубине 60-90 см составляет 1,05 % (1,033-1,065). Количество подвижного фосфора (P2O5) колеблется в среднем от 30,9 до 34,1 мг на 1 кг почвы, а обменного калия - от 317 до 327 мг. В опытах проведены работы на темно-серых почвах исследуемого региона с сортом риса «Хашими». Выявлены основные факторы изменения структурных элементов сорта риса «Хашими» в зависимости от приемов обработки. Установлено, что структурные параметры культуры риса менялись в зависимости от срока посева, рассады и норм удобрений. Представлены результаты исследований вариантов посадки риса в 1-и и 3-и декаде мая. Самые высокие показатели были получены на посевах в первой декаде мая при норме высева 1,7 млн/шт. рассады на гектар в режиме питания N120P80K60. Выявлена высокая корреляционная зависимость между структурными элементами урожая и почвенно-климатическими условиями на варианте без применения удобрений.

The main agrochemical indicators of the experimental field in the LankaranAstara region having dark gray soils have been presented in the article. The results of the analysis showed that the pH in the tillage layer of the experimental field is 6.12-5.87, in the lower layers, this figure ranged from 5.98 to 6.20. That is, the area has a weakly acidic property. There is no carbonation here as the pH of the experimental field soils is below 6.5. The experimental lands in the Lankaran-Astara region are considered to be of good quality. Because the amount of humus is 3.03-3.14 % in the tillage layer, and 1.63-1.73 % and 1.05-1.06 % in the lower layers. At a depth of 0-30 cm of the analyzed soils, the amount of mobile phosphorus (P2O5) varied on average from 30.9 to 34.1 mg per 1 kg of soil, and the exchangeable potassium varied between 317 and 327 mg. The field is moderately supplied with mobile phosphorus and exchangeable potassium. The key causesof the change in the biomorpholoical indicators and yield structural elements of the rice variety "Hashimi" depending on the cultivation factors have been given. Experiments with the “Hashimi” rice variety in the dark-gray soils of the Lankaran-Astara region showed that the biomorhpoıogical indicators and yield structural elements of the plant changed depending on the planting time, and seedling and fertilizer rates. The results obtained with variants planted in the 1st and third decade of May were slightly different. The highest indicator were obtained in the first decade of May, at the rate of 1.7 million seedlings per hectare and nutrition condition N120P80K60. A high correlation between the yield structural elements of unfertilized variants has been detected.
