Abstract
The effect of lime and phosphorus on the yields of velvet beans, crotalaria, cowpeas, and soybeans, is presented for eight crops harvested in the acid soil types Fajardo Clay and Catalina Clay, of Puerto Rico. Data for distances of plantings, age of crops, green and dry-weight yields for each of two consecutive crops of the leguminosae in each of four fields, and for the mean dry-weight yields of all crops are presented. Analysis for the total sum of squared deviations of the dry weight for the various crops, is also presented and discussed. Velvet beans, the highest yielder, gave, in the absence or presence of lime and phosphorus, mean green weights of 83.5 and 110.0 hundredweights per acre, respectively, equivalent to mean dry weights of 17.4 and 22.6 hundred weights per acre.Downloads
