Zinc (Zn) deficiency is considered one of nutritional constraints for crop yield worldwide. In recent past, the deficiency of Zn has heavily declined the quality of vegetables, especially tomato. Thus, a study was planned to enhance the growth, yield and quality of tomato plant using Zn and N alone and in combination. ZnSO4 was used as a source of Zn (10% and 12%) and urea as source of N (1% and 2%). The results showed that application of either Zn or N alone at both concentrations enhanced growth, yield and quality of tomato plants under poly tunnel. However, the combined use of both Zn and N further enhanced the growth, yield and fruit quality with application of Zn (12%) plus N (2%). Hence the combined use of Zn and N can be a viable strategy for improving yield and quality of tomato.
