摘要:

The estimation of the land equivalent ratios is proposed to be done by the (sum of) ratios of means of intercrop yield to sole crop yield. The bias and standard error of the estimates are obtained for large samples. Comparisons of the cropping systems have been made on the basis of these estimates and illustrated with field data.
