The influence of the method of cultivation upon the feeding value of some forage crops. 5. The influence of fertilization by N, P, and K on the digestibility and yields of nutrients of some gramineous forage crops. 6.

The crops studied were rye and oats, cut green, and Dactylis glomerata. N fertilization markedly increased the grass yield and percentage of digestible crude-protein, while it significantly reduced the percentage of N-free extract. The most efficient rate of application was 4kg. N/10 ar. P2O5 and K2O each at about 2.3 kg. per 10 ar. were necessary for the efficiency of the N fertilizer. N, P and K each increased the lignin content of the forage.
