Abstract: The field trial was conducted during both the seasons (2009-10 and 2010-11) on PGI Farm without changing randomization and analyzed on pooled basis. The experiment was laid out in Rabi season. The various components of growth attributes viz. no. of branches and plant spread were calculated at an interval of 28 days. The stomatal conductance and humidity were significantly more in irrigation level at 1.2 IW/CPE and planting on 44th MW (I3D2). The frequent application of irrigation at 1.2 IW/CPE ratio and early planting favours the development of microclimate including humidity (77 %) in the crop vicinity for better crop growth and development activities mainly at tuber formation stage (56 DAP) obtaining maximum tuber yield on pooled basis. It also recorded significantly higher values of biometric parameters viz., plant height, number of branches, plant spread per plant than rest of the treatments. The humidity value, growth parameters viz., plant height, number of branches, plant spread were significantly more with sugarcane trash mulching than without mulching. Favours the microclimate in the root vicinity, which affects the better tuber growth and development. Whereas, water stress condition impose due to without mulching at recorded significantly less values of these characters as compared to mulching.
