A 2-year study was conducted during 2002�2004 at Department of Soil and Water Engineering, Punjab Agricultural University, Ludhiana to investigate the effect of irrigation and fertigation on Greenhouse tomato. Drip irrigation at 0.5 × Epan along with fertigation of 100% recommended nitrogen resulted an increase in fruit yield by 59.5% over control (recommended practices) inside the Greenhouse and by 116.2% over control (recommended practices) outside the Greenhouse, respectively. The drip irrigation at 0.5 × Epan irrespective of fertigation treatments giving a saving of 48.1% of irrigation water and resulted in 51.7% higher fruit yield as compared to recommended practices inside the Greenhouse. Total root length was more in drip irrigated crop as compared to surface irrigated crop. Greenhouse tomato fruits founded superior than fruits of open field crop in view of fruit size, TSS content, ascorbic acid content and pH. Further, drip irrigation in Greenhouse crop caused significantly improvement in all the quality characteristics.
