The effect of various cultivation methods on the yield and quality indicators of nicotiana tabacum

In 2018-2020, the experiment was laid on a site with one type of relief. The experiment was carried out in 4 repetitions, 4 rows in each section, the length of each row was 10 meters. Soil of gray-forest-meadow type in the Sheki stronghold. 10 plants were selected from each experiment. Plant growth was measured every 15 days. After drying the collected leaves in the Rolla and Decloit drying chambers, the mass of dry leaves was determined. Due to the biological properties of Virginia tobacco varieties group, nitrogen (N) fertilization is not considered acceptable. For the first time in Azerbaijan, the effect of nitrogen fertilizers on the growth of tobacco variety Virginia Cocker 347 under irrigation conditions was studied. According to the results of the study in the growing season of 2020, it was found that the highest growth dynamics among the variants was obtained against the background of N45P120 + 20 tons and manure on an area of 90×40 cm. 70-80-50% of the irrigation rate was 253.4 cm, 70-80-60% of the irrigation rate 255.1 cm, 70-70-60% of the irrigation rate 251.4 cm. 27.7 hwt/ha when irrigated at 70-70-60%.
