Experiences were spent with domestic sorts Uzbekistan and Shark Yulduzi. The following schemes of accommodation and plants of density standing were tested： 70×30 cm and 90×23 cm at density of standing of 47,619 plants/hectares; 70×35 cm and 90×27 cm, 40,816 plants/hectares; 70×40 cm and 90×31 cm, 35,774 plants/hectares. The area of one plant feeding was 0.21, 0.245 and 0.28 ms. Schemes of accommodation and the area of plant feeding within the limits of the tested parameters do not render essential effect upon speed of plant development. Some acceleration （for 1-2 days） introductions into flowering are noted only at increase in the area of plant feeding with 0.21 ms up to 0.28 m^2. It was established that granting to plants of the greater feeding area as due to increase in distance between plants in the lines, and increases in row width strengthens growth of an elevated vegetative part of plants, especially due to increase amount of lateral branches. The greatest general and commodity harvest and the largest fruits sort ＂Uzbekistan＂ forms at density of standing in 40,816 plants/hectares, at schemes 90×27 cm and 70×35 cm, and more compact sort ＂Shark Yulduzi＂ at density of standing of 47,619 plants/hectares and the scheme 90×23 cm.展开更多
