Abstract :
One of the most important environmental factors that affect the growth and production of plants is the amount of available water. For this purpose, a factorial research was carried out in the form of a completely randomized design with three replications in Karaj during 2023 on the basil (Ocimum basilicum L.). Research factors included water consumption amounts at four different levels 4000, 5000, 6000 and 7000 m3/ha and the second factor included two different varieties (green and purple basil). The results of present study showed that irrigation treatments had a significant effect on all studied traits. So, with increase in irrigation amount (irrigation of 7000 m3/ha), all studied traits had a significant increase compared to others. The green basil variety had the highest dry matter yield compared to the purple variety, and dry matter yield increased with increase in irrigation amount. But the photosynthetic pigments were more in the purple variety than green. Thus, the highest dry matter yield (177.09 g/m2) was related to interaction effect of 7000 m3/ha water consumption and green basil. The lowest amount of yield dry matter (75.35 g/m2) was observed in 4000 m3/ha and purple basil. Therefore, due to high yield of dry matter, the green variety is more suitable for cultivation than the purple and has a higher economic efficiency. So, it is recommended to cultivate the green variety with 7000 m3/ha water using to get the highest quantitative and qualitative yield of basil.
