YIELD AND MARKETABILITY OF POTATO VARIETIES WITH DIFFERENT NUMBERS OF IRRIGATION SCHEMES AND FERTILIZER STANDARDS IN CASE OF UZBEKISTAN
Keywords:
fertilizer, manure, haulm, qualityAbstract
In the study, we have been trying to show the results of the middle-ripened varieties of potato at different numbers, schemes, irrigation techniques, and fertilizer rates and their influence on growth, development, and crop formation, yield, keeping quality, transportability, biochemical composition and quality of tubers are presented. The optimal number of irrigation (9 irrigation schemes according to the 1-2-6 scheme), irrigation technique (the length of irrigation grooves is 60 m, and the speed of water flow in the sulcus is 0.1 l/sec) and the fertilizer rate (20 t/ha manure + N200P160K100 kg/ha), contributing to favorable conditions for plant growth and development, the formation of a powerful haulm, leaf device, root system and as a result of obtaining a high (32-35 t/ha) yield with high and normal quality
