Abstract

The 3 pearl millet cv. Katherine Pearl, Tamworth and Tiflate, representing mid-season and late-season types, were grown at Camden, New South Wales. Crops were sown in Nov. and Dec. and cut at heights of 10, 30 and 50 cm, at 3- and 6-weekly intervals, beginning 6 weeks after sowing. Both total and late-season forage DM yields were highest under a lenient cutting regime. Late-season productivity was higher in late-maturing cultivars. The effect of late sowing was to increase the yield and quality of late harvests, but not total yield. The yield of the hybrid Tiflate was low. Total harvested forage plus final stubble averaged 11 t DM/ha for the 3 cultivars. Forage quality, as assessed by leafiness, protein and OM digestibility, was high. With the exception of digestibility, quality was improved by intensive cutting. Late-season digestibility was little influenced by cutting treatment. Early DM content of all cultivars was low, and could adversely affect animal production. The results indicated that for the realization of high, well-distributed yields concomitant with quality, a tall stubble of about 30 cm, frequently harvested, was desirable. For late-season productivity, the use of a late-maturing cultivar could offset the effect of late sowing
