Row spacing and seeding rate on some agronomic characteristics of rapeseed

, : Row spacing and seeding rate on some agronomic characteristics of rapeseed. Pesquisa Agropecuaria Brasileira 24(5): 567-572

For three years, from 1980 to 1982, at several locations in Rio Grande do Sul state, Brazil, the effect of row spacing and seeding rate on some agronomic characteristics of rapeseed (Brassica Napus L. var. olelifera Metzg.) was evaluated. Locations, year and seeding rate were the main factors influencing yields of rapeseed. Pooling the date by year showed a significant effect of seeding rate on yields; the highest yields were observed under the lowest seeding rate. There was no significant effect of row spacing but there was a significant interaction with locations and years.
