The relationship between plant quality and yields of glasshouse tomatoes.
AbstractThe results of experiments on tomato plant raising methods for early cropping under glass showed that the quality of the planting material as assessed by the subsequent crop yield was largely determined by size. A further study of growing methods on 55 nurseries showed that in all cases the plants used for December planting for the early 1969/1970 crop were too small. Multiple regression equations showed that for crops harvested before 18 April, 1970, plant size influenced earliness more than yield. In addition, the higher the plant nitrate content the later was the date of the first pick and the higher the Na content the lower the yield.
