Abstract: In order to find an optimum cultural program for Feng Kang 10 wheat in the Ji Dong Plain, such controllable factors-sowing season, sowing rate, irrigation, the time and level of fertilization-as exert great influence u-pon wheat production, were selected as variants by the use of quadratic quadrture/rotational regression combination design based on the principle of agricultural system engineering. Six indice inlcduing yield and net value of production were selected as target functions. Pneumatic imitation and statistical analysis of several thousand combinations were completed through multi-spot experiments and mini-computer computation. Three agronomic Combinations were found with yields of about 200, 300, and 400 kilograms. mu-1. and net production values of 80, 100, and 120 yuan.mu-1. Optimum cultural programs for 5 yield areas were found in accordance with the local conditions of agricultural production and the growth requirements of wheat.

Key words: Feng Kang 10 wheat, standardised cultural technique
