A Field experiment was carried out at Eastern block, Tamil Nadu Agricultural University, Coimbatore during summer 2016 to study the effect of mechanized and conventional cultivation on physiological growth parameters of cotton under varying crop geometries. The experiment was laid out in split plot design and replicated thrice. The treatment comprised of two cultivation methods viz., mechanized cultivation (M1) and conventional cultivation (M2) were assigned in main plot and four spacings viz., 45 cm x 15 cm (1,48,148 plants/ha) (S1), 60 cm x 15 cm (1,11,111 plants/ha) (S2), 75 cm x 15 cm (88,888 plants/ha) (S3) and 75 cm x 30 cm (44,444plants/ha) (S4) in sub plot. The results of this study revealed that cotton under mechanized cultivation with closer spacing of 45 cm x 15 cm (M1S1) recorded higher physiological growth parameters of leaf area index, leaf area duration and crop growth rate.
