Cultivation factors effect on the Hashimi variety rice efficiency

The main agrochemical indicators of the experimental field in the Lankaran-Astara economic 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 economic 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 highest indicator was obtained in the first decade of May, at the rate of 1.7 million seedlings per hectare and nutrition condition N120P80K60.
