Production and physiological responses of Italian ryegrass and white clover grown in monocultures and mixed stands

“…Furthermore, the saving in nitrogen fertilizer in such a grass/legume pasture may be considerable. High levels of nitrogen fertilizer are required for individual grass swards in excess of 400 kg N ha-1 (Dannhauser 1980), while only "starter" nitrogen is required in mixtures. Frame and Newbould (1986) stated that white clover (Trifolium repens cv.…”

“…Lolium multiflorum is considered the most important temperate grass species in South Africa, due to its superior winter yielding capacity (Van den Berg and Kruger 1989). However, to obtain acceptable dry matter production, very high nitrogen applications in excess of 400 kg N ha-1 (Dannhauser 1980) are necessary. The Midmar cultivar has an erect growth habit and reacts favourably to ni trogen fertilization.…”

“…The yield of ryegrass in various parts of South Africa varies considerably, depending on the type of soil, fertilization, climate, irrigation and management. A production of 7 to 9 tons ha -1 under irrigation appears to be a good average, although a yield of 12 tons ha-1 is not impossible (Dannhauser 1980 andMorrison 1980). Dannhauser (1980) also stated that if irrigation is utilized, the farmer can successfully include ryegrass in his feed production program as it is high yielding and has both high nutritional value and carrying capacity.…”
