摘要：An analysis of a 1999 sample of 13 no-till producers indicates that over a reasonable range of cotton lint prices, ultra narrow cotton production may result in larger net returns per acre than conventional production practices. The largest percentage cost reduction is in fixed expenses. In general, total direct expenses per acre are also reduced, although UNRC usually results in higher seed and chemical expenses. UNRC has a lower total cost per pound compared to conventional cotton.
