摘要

Forage, seed yields and herbage chemical composition of phasey bean (Macroptilium lathyroides) were investigated at 3 intra-row plant spacings (15, 30 and 45cm between plants; 50 cm between rows), 4 phosphorus (P) fertilizer application rates (0, 50,100 and 150 kg/ha P) and 5 harvest stages (uncut control 6, 9, 12 and 15 weeks post sowing) in two growing seasons at Shika in northern Nigeria. The least intra-row plant spacing (15cm) produced higher (p<0.01) total DM yield (1.50 t/ha) than wider spacings. The proportion of leaf was least (40 %) in the widest spacing compared with other spacings (59-62 %). The P-fertilized plots produced 58-60% more total DM yields than the unfertilized plots and total DM yields increased with advanced plant growth-The highest percentage (61-63) of leaf was recorded from 6 to 12 weeks post sowing. Nitrogen level in herbage increased (p<0.05) with increased intra-row plant spacing and P application. Phosphorus and Calcium. Levels in herbage did not respond to intra-row plant spacing but increased with P application. The Ca:P ratios at the han'esi stages were between 4:1 and 6:1. The highest seed yields (198 and 188 kg/ha) were recorded respectively in the least intra-row plant spacing and the application of WO kg P/ha. Supplementation of calves on grasses cereal stovers with phasey bean hay in a sustainable crop/livestock production systems is suggested.
