Abstract:
The comparatively higher price of grafted seedlings has limited the wide-spread adoption of this technology among growers in North America. The objective of the current study was to determine if grafted tomato(Solanum lycopersicum) seedling populations could be reduced while maintaining desirable yields. This study also examined the efficacy of utilizing root-knot nematode-resistant rootstocks at controlling the formation of root galls, also to determine if grafting had an impact on fruit quality. In all studies, 'Tribute' as a scion was grafted onto 'Multifort' and 'RST-04-106-T', respectively. Non-grafted and self-grafted'Tribute' were included as controls. Organically managed field trials were conducted during fall 2012 and spring 2013. In spring 2013 there was a concurrent conventionally managed trial. A split-plot design with four replications was used with in-row spacing as the whole-plot factor (0.46, 0.61(recommended spacing), 0.76, 0.91, and 1.07 m) and grafting treatment as sub-plot factor. In fall 2012 and spring 2013 conventional trials the use of 'Multifort' at increased in-row spacing treatments of 0.76 m and 0.91 m produced significantly higher marketable yields per hectare than non-grafted control at the recommended spacing (P= 0.01). This suggests that grafted plants could be planted at lower planting densities to increase yield and defray the cost of grafted seedlings. In the spring 2013 and fall 2012 organic trials, grafting significantly reduced the severity of root galls(P= 0.01). The fruit quality attributes including total soluble solids content, fruit pH, titratable acidity, and ascorbic acid content were not significantly affected by grafting.
