| Abstract/Description: | The field experiment was conducted at main agricultural research station, UAS, Dharwad during kharif season of 2013 to study the effect of chemical defoliator application on yield and economics of compact cotton genotypes. Treatments consisted of 12 combinations comprising of two genotypes (G1 -RAH 274 and G2 -SC 2028 22) as main plots, two spacing levels (S1 :45x10 cm and S2 :45x15 cm) as sub plots with three chemical defoliator (D1 : Dropp Ultra @ 200 ml/ha, D2 : Ethrel @ 2000 ppm and D3 : Water spray) as sub sub plot treatments. Results revealed that genotype RAH 274 with spacing of 45x15 cm along with application of chemical defoliator Ethrel @ 2000 ppm recorded higher seed cotton yield (2241 kg/ha), gross returns (Rs. 100830/ha), net returns (Rs. 67910/ha) and B C ratio (3.06) over other interactions. Similarly, the same interactions recorded higher yield attributes viz., sympodial branches per plant, number of bolls per plant, per cent boll open and yield per plant which resulted the higher seed cotton yield and economic returns. However, this treatment with spacing of 45x10 cm recorded significantly higher leaf defoliation (99.8 %) and superior over others. |
