Transplant Age and N and P Nutrition Effects on Growth and Yield of Tomatoes

Year: 1989

Type: article

Abstract: ‘Pik-Red’ tomato ( Lycopersicon esculentum Mill.) transplants grown in the greenhouse were fertilized with three levels of N and P. Nitrogen at 400 mg·liter -1 and P at 30 mg·liter -1 had produced the largest transplants at 5 weeks after sowing. Nitrogen at 100 mg·liter -1 produced the largest root : shoot ratio. Phosphorus had no effect on root : shoot ratios. Plants fertilized with moderate and high N levels in the greenhouse produced larger early yields in the field, but there was no effect of N or P level applied in the greenhouse on total yield. Four- and 5-week-old plants produced greatest total yields.
