Description
This paper describes grassland development in Peru. Vegetation of the high alpine region of Peru, which occupies some 4 million ha, is dominated by native grasses normally producing less than 2,000 kg/ha dry matter annually. On land with adequate soil moisture, pastures based on perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) were established successfully, but on drier sites alfalfa proved superior, producing over 12,000 kg/ha/yr in some trials. Alfalfa and clovers were also successfully introduced into improved native pastures by mechanical direct seeding and by hand sowing. With direct seeding, dry-matter production increased from about 600 to 6,000 kg/ha in 2 years and to more than 10,000 kg/ha in older swards. Inoculation of legumes proved essential. The effectiveness of the inoculants was enhanced by increasing the rate of inoculant, using lime-inoculated and -pelleted seed, or sowing 500 kg/ha lime with the seed. Excellent results were obtained from sowing turnips (Brassica rapa L.), 8,000 to 10,000 kg dry matter/ha being produced in 5 to 6 months. Pasture establishment and development have resulted in production increases up to 10-fold and animal-carrying capacity and performance have been increased correspondingly.
