The Effect of major Cultivation Factors on the Growth Dynamics and Biological Productivity of Cereal Crops under Short Rotation Crop Systems in Different Agroecological Conditions

During the research, the highest indicators for both crops at the Absheron AEF were obtained under soil cultivation at a depth of 20‒22 cm (plowing + discing + cultivation) and the application of N120P90K60 fertilizers for winter wheat, and for barley under the same soil treatment with N100P90K60 fertilizers. In the traditional soil cultivation system for winter wheat and barley, depending on the applied fertilizers, the dry matter mass was 1559.2‒1025.1 g, the mass of grain per plant was 509.1‒452.3 g, the number of productive stems was 397‒365 units, and the mass of 1000 grains was 45.0‒41.8 g. In the variant with heavy disc cultivation at a depth of 10‒12 cm with two passes, these indicators were 1417.6‒940.1 g; 443.4‒400.3 g; 344‒323 units, and 43.2‒40.0 g respectively. The results of soil cultivation in the semi-arid conditions of the Jalilabad Regional Experimental Station showed different results compared to the Absheron AEF. Under the use of N80P60K45 and N60P60K40 fertilizers for winter wheat and barley, and with the heavy disc cultivation at a depth of 10‒12 cm with two passes, the dry matter mass was 875.0‒670.2 g, the mass of grain per plant was 303.3‒275.4 g, the number of productive stems was 270.3‒316.3 units, and the mass of 1000 grains was 49.9‒46.2 g.
