The fertilizing value of green manures rotted under different conditions
1934
Daji, J.A.
1. Young tares, young mustard, and sugar beet tops had a beneficial effect on the barley crop when used as green manures. They accelerated germination, increased the tillering capacity, and gave bigger yields of grain and straw than the control. This was true of all three manures in whatever way they were applied. The same applies to the artificial fertilizers. 2. The yield of grain and straw was correlated with the tillering capacity, but was not affected by the height. The increased tillering and yield were primarily due to the fertilizing elements contained in the green manures, chiefly the nitrogen. 3. The green manures when buried at once gave higher yields of grain and straw than when they were applied to the surface or when they were rotted separately. 4. The fertilizing value of the different methods of applying the green manures depends on the abundance of available nitrogen returned the treated manure for the use of the crop. The extent to which the abundance of nitrogen will be maintained in the treated manure depends on the nature of the green manure, the amount and nature of nitrogen originally present in the green manure, and the conditions under which the material is decomposed.
