Euryale ferox Salisb. (fox nut / makhana / gorgon plant) belonging to water lily family viz, Nymphaeaceae, is one of the important cash crops of North Bihar, particularly in the districts of Darbhanga, Madhubani, Saharsa, Purnea and Katihar. Polynomial Regression is a form of linear Regression in which the relationship between the independent Variable x and the dependent Variable Y is modelled as an nth degree polynomial. Polynomial regressions, also known as Polynomial least squares fittings.Starch was the higest content of Euryale ferox, its structure and characteristics were critical in processing. Edible perisperm of makhana costitutes 80% starch .Nath & Chakraborty (1985) reported 77% starch in the perisperm. Starch content in the kernel of over – mature fruits (236 DAS,day after sowing)) in comparison to 1/3rd mature ( 176 DAS) ones is about 0.96 : 1: 1-fold respectively under conditions of 0.0001% , 0.001%, & 0.01% kinetin after 1min and the ratio is about 1: 1.26: 1.46-fold in 5min treatment, the higher concentration of treatment, the higher amount of starch content is produced.
