Description
Seed production of smooth meadow grass (Poa pratensis L.) cv. Lavang was compared at 3 sowing rates (2.5, 5.0 and l0.0 kg/ha) and at 2 row spacings (16.5 and :n cm), the wider used in conjunction with carbon banding. Results varied between fields according to temperature after planting and the weed content of the soil, but, on average, 5.0 kg/ha proved to be the optimal sowing rate. 33 cm row spacing and carbon banding caused a higher proportion of tillers to develop panicles and gave a higher seed yield with a better weed control in the first and third harvest year, but the method was inadequate for the control of Poa amma and Alopecurus geniculatus L. in the second year.
