Abstract
Field trials in the Markham Valley, Papua New Guinea showed that forage sorghum cv. Zulu [Sorghum bicolor X S. sudanense] cv. Sudax 11a, Columbus grass (Sorghum almum) and sorghum cv. NK 300F (grain and forage type) sown in Nov. 1973 produced higher av. DM yields and persisted longer than 2 millets hybrid cv. MX001 [species not stated] and white panicum (Echinochloa crus-galli). When cut at monthly intervals, the millets disappeared after 4 or 5 harvests while the sorghums were still yielding well 1 yr after establishment. Application of N improved sorghum yields at all harvests, but millets did not respond. Zulu showed the highest response to low N levels of 166 kg/ha, rising from 13.78 t DM/ha with no N to 18.37 t/ha. Other cv. showed a linear response up to 332 kg N/ha, increasing from 13.12 t/ha with no N to 16.37 t at low N and 18.53 t at high N. DM yield, N content and N yield all declined with maturity. A comparison of forage sorghums under a monthly grazing regime showed Zulu to have the highest DM yield, tillering capacity, plant population and persistence after 8 months, whereas NK300F was notably sensitive to grazing in these dry conditions. It was concluded that, with proper management, forage sorghums, particularly cv. Zulu, could supply useful quantities of feed for 1 yr before re-sowing, even during dry periods
