Effect of Pot Size and Hydroponics Technique on Growth and Yield of Lettuce(Lactuca sativa L.)

The current experiment was conducted from November 2021 to January 2022 at Nursery of the Directorate of Agriculture Kirkuk / Kirkuk governate, Iraq, to study the effect of pot size (250, 150, 100 ml) and hydroponics technique (Deep Water Culture and Nutrient film) on growth and yield of lettuce, which were placed in the main panels of statistical design.The experiment design was split plot System, within the design of the complete random sectors and four replications while, the averages were compared according to the Duncan polynomial test at the level of probability of 5% p.The main results exceeded that the size of the pot 150 ml in deep water culture significantly in most of the studied characteristics, including the average weight of the head, total and total quotient, with a significant increase of 17.53 and 17.70%, respectively.
