Studies on grass silage from predominantly Paspalum dilatatum pastures in south-eastern Queensland. 3. Influence of fertilization with nitrogen and method of harvesting on silages with and without the addition of molasses

Abstract

Experimental tower silos of 0·75 ton capacity were used in a comparison of five silage treatments: (1) pasture top-dressed with 65 lb N per acre, harvested by cutter-bar and ensiled without molasses; (2) as for silage treatment 1, but ensiled with the addition of molasses at the rate of 40 lb per ton of green matter; (3) pasture from an unfertilized area, harvested by cutter-bar and ensiled without molasses; (4) pasture top-dressed with 65 lb N per ac, harvested by flail and ensiled without molasses; and (5) as for silage treatment 4, but ensiled with the addition of molasses at the rate of 40 lb per ton of green matter.
