J.R. Finlay, of the Atoll Research and Development Unit at the University of the South Pacific, reports that split applications of nitrogenous fertilizers give higher yield increases than single applications. Finlay's work m Kiribati also indicates that the effect of compost is inferior to that of equivalent amounts of inorganic fertilizers for short-term crops. In his studies, trickle irrigation produced higher yields than other methods in sweet potato. In Pandanus, terminal stem cuttings (1-2cm in length) were found to develop roots readily when moisture and aeration were adequate. Studies by S. Ochetim at USP Alafua, on the use of locally-available ingredients in the feeds of pigs and poultry indicate that copra cake can be successfully included in up to 70% of a pig's diet, 60% of a layer's diet and 33% of a broiler's diet. His studies show that up to one-half of this copra can be susbstituted with dried brewers' grains and that cassava and sugar cane can replace imported grains in diets. For small-scale production complete diets can be formulated using a combination of cassava, freshly-grated coconut, breadfruit, copra and copra cake, sweet potato vines, molasses, freshly-mixed fish, meat and bone meal, green grass, coral sand and salt.
