The article is devoted to the introduction of the “Studying of the effect of external conditions and components of agro-technical cultivation components on falling degree of vegetative organs of cotton plant” which was started in 2011, where the plant density is also described. The experiment was carried out in the plots with 100m length, 4- rowed fields by 4 repeats and 12 options. The size of each of the rows was 240 m², total experimental plot equaled 240 x 12 x 4=11520m².

By that purpose observation over plant densities had been conducted in the experiments which were based on introduction of microelements at two periods, on background of fertilizers N₁₀₀ P₁₀₀ K₅₀, two plant densities and three deeply varying irrigation regimes. The factors affecting on decline at 6020x1; 60x20x2 plant density, dependence between plant density and mass of a ball, plant density and productiveness are determined.
