DRESSING OR SPRAYING CALCIUM FOR BITTER PIT CONTROL |
| Author: | J. VAN DER BOON |
| Abstract:
Bitter pit in apples can be controlled partly and sometimes entirely by intensive spraying with a solution of calcium nitrate or chloride during the growing season (Naumann, 1974; Van Goor, 1971). However, from a practical point of view, it would be more economic and convenient to replace frequent spraying, if possible, by a single soil dressing and a study was therefore made of the comparative effectiveness of four levels of liming, gypsum dressing and spraying with calcium nitrate on the incidence of bitter pit and breakdown to determine whether these measures could replace or supplement one another. | |
