N2  - A study was made in seed boxes at Armidale, New South Wales, on a red earth soil, of the effects of two soil tilths (particles<0.3 cm and between 0.6 and 1.25 cm), three seeding depths (surface seeding, 1.25 cm and 2.5 cm), and three levels of applied phosphorus (the equivalents of phosphorus in nil, 378 kg/ha and 756 kg/ha superphosphate, applied as sodium di-hydrogen phosphate) on emergence and early seedling growth of Phalaris tuberosa. Water was made non-limiting as far as practicable. Seedling counts were made every four days until the first harvest, 32 days after sowing. Four fortnightly destructive harvests were made to examine treatment effects on post-emergence seedling growth. Seeding into the fine tilth at a depth of 1.25 cm on the high phosphorus treatment gave the fastest and highest total seedling emergence. Conditions most favourable to immediate post-emergence seedling growth were sowing into a fine seedbed at a depth of 1.25 cm or 2.5 cm in combination with phosphorus ; the rate of seedling growth increased with rate of phosphorus applied.
