Effects of plant density, row spacing and row orientation on yield and achene quality in rainfed sunflower
2001
Long, M. | Feil, B. | Diepenbrock, W.
A large body of literature on the responses of yield and other agronomic traits to planting patterns in rainfed sunflower (Helianthus annuus L.) is reviewed. Extensive studies on the effect of plant density on yield have given inconsistent results which are still not well explained by other agronomic traits. The effects of row spacing on yield and other traits seems to depend greatly on the environment where the trial is conducted and on the cultivar used. Information on the effect of row orientation is scarce and needs to be further studied over a large range of latitudes with the assistance of simulating models.
