Abstract: The experiment was carried out on the experimental farm in Tunliu of Shanxi province during 1987 - 1988.Through quadratic regression orthogonal rotational combinatorial design the quatitative comprehensive study was made about the key agronomic measures of sowing density, sowing time, N, P and manure fertilizer application amount, and the optimum synthetic design of agronomic measures was preliminarily determined.Both single reactions on the millet yield and interactions of all agronomic measures were also studied using yield reaction model.After application on a small scale and comparison, the optimization plant was proved to be feasible and profitable.

Key words: Millet, Arid land, Cultural measures, Mathematical models, Yield
