e0“Two rootstocks and three nitrogen fertilizer rates were evaluated for their effects on growth, yield, and petiole nutrient concentrations of Chardonnay (Vitis vinifera L.) grapevines”
e5“yields averaged 4.55 and 4.45 kg per vine in 1984 and 1985, respectively, with vines grafted to C-3309 and 4.08 and 4.13 kg per vine, respectively, for vines grafted to Elvira”

Other claims from this paper (13)
- Intervention effect Rootstock had a greater effect on scion growth than differential nitrogen application in Chardonnay grapevines in New York.
- Intervention effect Increased nitrogen availability significantly increased petiole N concentrations in the second year of application.
- Observation Cane pruning weights of vines grafted to Couderc 3309 (C-3309) rootstocks averaged 1.42 and 1.20 kg/vine in 1984 and 1985.
- Observation Cane pruning weights of vines grafted to Elvira averaged 0.75 and 0.79 kg in 1984 and 1985.
- Observation Yields of vines grafted to C-3309 averaged 4.55 and 4.45 kg per vine in 1984 and 1985.
- Intervention effect Increased nitrogen availability reduced yields with vines grafted to C-3309.
- Intervention effect Increased nitrogen availability increased yields in one year with vines grafted to Elvira.
- Association The percentage of flowers setting fully developed berries in 1985 was greater for Elvira than for C-3309 vines.
- Intervention effect Fruit set of non-fertilized C-3309 vines was greater than fruit set of vines receiving 84 kg N/ha.
- Association C-3309 vines had greater shoot growth rates than Elvira vines.
- Association C-3309 vines had greater petiole potassium concentrations than Elvira vines.
- Association C-3309 vines had denser canopies than Elvira vines.
- Intervention effect Neither rootstock nor applied nitrogen affected the duration of vegetative growth.
