Abstract: The field experiment was conducted at Agronomy Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidypeeth, Akola during Kharif season 2014 to evaluate the Effect of high plant density and fertilizer levels on performance of hirsutum cotton under rainfed condition. The experiment was laid out in split plot design consisting three levels of plant densities viz., S₁- 1,66,666 plants ha^-1 (60 x 10 cm²), S₂- 1,11,111 plants ha^-1 (60 x 15 cm²) and S₃- 55,555 plants ha^-1 (60 x 30 cm²) in main plots and three fertilizer doses i.e. F₁- 100% RDF (50:25:25 N:P₂O₅:K₂O kg ha^-1), F₂- 150% RDF (75:37.5:37.5 N:P₂O₅:K₂O kg ha^-1) and F₃- 200% RDF (100:50:50 N:P₂O₅:K₂O kg ha^-1) in sub plots. The results revealed that the plant density of 1,66,666 plants ha^-1 produced significantly superior seed cotton yield (kg ha^-1) over plant density of 55,555 plants ha^-1 (kg ha^-1) and it was at par with plant density of 1,11,111 plants ha^-1. Among the fertilizer levels application of 200% N:P₂O₅:K₂O kg ha^-1 produced higher seed cotton yield over 100% N:P₂O₅:K₂O kg ha^-1 but at par with application of 150% N:P₂O₅:K₂O kg ha^-1. In case of yield contributing character viz., number of harvested bolls plant^-1, seed cotton weight per plant (g), 50 % Flowering were recorded significantly superior by plant density of 55,555 plants ha^-1 over the higher plant density of 1,66,666 plants ha^-1. The application of 200% RDF produced the maximum number of harvested bolls per plant, weight of seed cotton per plant and 50 % flowering than 150% RDF and 100% RDF.
