Abstract: Field studies were conducted at the Morden Research Station to determine the maximum levels of P that can be placed with or near the seed. In 1983-1984, the cultivar manor was grown with four levels of P (0, 50, 100, 150 kg ha-1 P2O5) as triple superphosphate (0-46-0) with five band placement methods using hoe openers and a 30 cm row spacing. The 50 kg ha-1 P2O5 rate had no detrimental effect on seedling stands or seed yields. However, the highest levels of P (100 and 150 kg ha-1 P2O5) applied with the seed caused reductions in seedling stands in one of the three years, but did not decrease seed yields.
Key words: buckwheat, Fagopyrum esculentum, phosphorus, plant nutrition
