Title: Field Trials. of Sunflower Resistant to Bird Depredation
Author: Linz, G .M.; Hanzel, J.J.; Fox, G.J.; Stehn, R.A.; Woronecki, P. P.; Dolbeer, R.A.
Description: Due to the damage caused by wild birds created for commercial sunflower growers in North Dakota, the development of a bird resistant variety of sunflower would resolve this problem. Crop resist may be derived from chemical or morphological changes in the plants. This report is the description of a series of investigations in both North Dakota and Ohio to examine bird damage to two experimental varieties of sunflower, BRS-1 and NdC. Even with the infusion of resistant characteristics to various lines of sunflower the total elimination of damage. With each incremental decrease achieved in sunflower seed feeding by birds, there need be a concurrent increase in the feeding on insects and weed seeds.
