Abstract

An experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during Rabi 1985-1986 and Kharif, 1986 with five irrigation treatments and six N levels. Of the production models viz., square root, three halves, quadratic and Cobb-Douglas tried, it was found that quadratic model gave the best fit, indicating that finger millet (CO 11) required optimum quantities of water and N for increased grain yield.

Keywords: Fingermillet, Production Function, Water, Nitrogen.
