Synopsis Species exhibiting superior recovery capacity, rape and sudangrass, produced highest drymatter yields. Considering the first cutting only, differences in percent crude protein and dry‐matter yields among crops were highly significant (P=0.01). Harvestdate delay, studied over a 3‐week period, resulted in an approximate 340‐pound‐per‐acre dry matter increase to each percentage point decline in crude protein. Moisture percentages of early‐summer crops decreased more rapidly with advancing maturity than those of late‐summer crops.
