Agriculture has been indispensable for the subsistence of the people of India in general and farmers in particular. It has naturally been the cornerstone of the Indian economy since time immemorial and agriculture has played a major role in the country's economy since its inception. The research work was done to study the effect of irrigation levels on the yield and growth of winter marigolds. Marigold (Tagetes erecta L.) had been taken twice the winter season of 2019-20 and 2020-21. The average flower yield (t/ha) was recorded under the treatment I1 (12.03 t/ha) was found maximum and it was followed by I2 (10.51 t/ha), I3 (9.73 t/ha). The consumptive water use (CWU) was found maximum (26.62 cm) in 100% of ETc and the lowest CWU was found (21.03 cm) in 80% of ETc through a drip system of irrigation in the cropping year 2020-21. Similarly, in 2019-20 CWU was found maximum (18.02 cm) in 100% of ETc, while the lowest CWU was found (14.42 cm) in 80% of ETc. The water use efficiency was found highest in I3 (0.77 t/ha/cm) and minimum WUE was found in I2 (0.525 t/ha/cm) in the cropping year 2019-20. For 2020-21, a maximum WUE was recorded in I2 (0.497 t/ha/cm) and the minimum WUE in I3 (0.335 t/ha/cm).
