Other claims from this paper (15)
- Intervention effect Sprays had no effect on fruit maturity status at harvest compared with water-sprayed control trees.
- Intervention effect Sprays with Rosatop increased fruit calcium concentrations after 8 weeks and at harvest.
- Intervention effect Sprays with Rosatop plus Ca(NO3)2 increased fruit calcium concentrations after 8 weeks and at harvest.
- Intervention effect Sprays with Ca(NO3)2 alone increased fruit calcium concentrations, except in 2000.
- Intervention effect Sprays with Ca(NO3)2 in 2000 did not affect fruit calcium level at harvest.
- Intervention effect Spray treatments did not influence fruit nitrogen, phosphorus or potassium status.
- Intervention effect Spray treatments did not influence fruit magnesium or boron status.
- Intervention effect In 2 of 3 years, fruit sprayed with Rosatop plus Ca(NO3)2 were firmer and less affected by internal breakdown after storage than control fruit.
- Intervention effect In 2 of 3 years, fruit sprayed with Ca(NO3)2 alone were firmer and less affected by internal breakdown after storage than control fruit.
- Intervention effect Foliar Rosatop sprays decreased fruit sensitivity to bitter pit in all years.
- Intervention effect Foliar Rosatop plus Ca(NO3)2 sprays decreased fruit sensitivity to bitter pit in all years.
- Intervention effect Ca(NO3)2 sprays decreased fruit sensitivity to bitter pit, but only in 2 growing seasons.
- Intervention effect Spray treatments did not affect soluble solids concentration or fruit decay after storage.
- Recommendation Spring sprays with Rosatop material can be recommended in apple orchards on coarse-textured soils with low B concentrations to increase fruit resistance to physiological disorders.
- Recommendation Foliar Ca fertilizers richer in B than Rosatop material should be used in spring spraying to improve tree cropping.
