THE EFFECT OF SOWING SCHEME ON THE YIELD PARAMETRES OF SUNFLOWER VARIETIES

Abstract

Sunflower (Helianthus annuus L.) is one of the most important oilseeds in the world today. Sunflower oil ranks first among vegetable oils selected in terms of quality. Therefore, in many countries around the world, the level of economic efficiency is increasing depending on the area under crops and the amount of harvest. The main way to increase the yield of sunflower is to cultivate modern fast-growing varieties that are adapted to the soil conditions of the region for each region. This scientific article develops the main elements of the technology of cultivation of oilseed sunflower as a secondary crop of high yields from early ripening varieties. Sowing sunflower as a secondary crop after wheat resulted in increased yields when planting schemes were applied correctly. Depending on the number of seeds in one basket and their weight sowing schemes, the elements of the crop - basket, number of seeds, weight and yield increase were proved when the seed sowing scheme was 70x30-1 as a repeat crop.
