Abstract
Abstract Flax (Linum usitatissiumL.) was grown in field experiments over a five year period on a calcareous and a non‐calcareous Orthic chernozemic soil that were both low in NaHCO3extractable P. Six rates of P‐fertilizer as mono‐ammonium phosphate (MAP) were applied at seeding using four placement methods: 1. broadcast and cultivated 10 cm into the soil (BC); 2. banded in the seed row with the seed (PWS); 3. banded 2.5 cm below and 2.5 cm to the side of the seed (PSS); 4. banded 2.5 cm directly below the seed (PBS). Soil type, broadcast application of ? (BC) and application of low rates of ? using the PWS method had no significant effect on flax growth, seed yield and P‐uptake. Reduced emergence of flax occurred on the PWS when the rate of ? was 15 kg ha‐1or greater. The reduced crop emergence resulted in reduced seed yield and P‐uptake. With 15 to 25 kg ha‐1P seed yield was reduced by 28% to 62%. P‐fertilizer applied by both the PSS and PBS methods increased flax growth, seed yield and P‐uptake. Both methods produced similar quantities of dry matter and similar P‐uptake during the growing season, however, at harvest the PBS method produced the greater quantity of seeds and resulted in removal of the larger quantity of ? by the crop. With both the PSS and PWS methods the harvest index of flax decreased with increasing rates of fertilizer P. The greater efficiency in ? use recorded for the PBS treatments over those of the PSS treatments was due to higher ? uptake early in the growing season, increased seed production, and lower harvest index values
