The effect of potash in the base dressing on the incidence of simple fruit ripening disorders. A specific study of an autumn crop of tomatoes on an old glasshouse soil at a high phosphate level: A thesis submitted in partial fulfilment of the requirements of the Royal New Zealand Institute of Horticulture for the National Diploma in Horticulture

Abstract

These studies concern an autumn crop of tomatoes planted early February in good light and high temperatures. By planting in February in good light, at least one conflicting aspect is removed: the effect of shorter days and poorer light of spring. Four commercial varieties were used. It is hoped that some value will come out of these trials to guide our husbandry.
