Abstract: he influence of soil chemical properties and soil nutrition on cotton yields was studied by means ofestablishing mathematical models. The nultivariate quadratic regression equations developed by a stepwiseregression method not only presented the single effect of soil factors but also displayed the interaction （syn-ergistic or antagonistic） of soil nutrients. The effect of individual factor and the way of nutrient interactionwere further analysed by the path ... More
