2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

The results revealed significant improvement in cane weight‚ cane formation cane and sugar yields due to reduced cane lodging in treated plots against control. A measurable increase in cane yield and CCS up to 15.26 and 14.68 % was recorded in the plots where Modus was applied along with earthing up‚ respectively.
