Abstract EN
The plastic-house experiment was carried out at University of Sulaimani, College of Agricultural Sciences during the growing season of 2016-2017 to determine the effect of soil and foliar application of humic acid on yield and yield components of Lettuce (Lactuca sativa L.var Romaine).
Four humic acid concentrations (ml.L-1 ) were sprayed, and soil application of humic acid in four levels that were soil addtions.
The design of experiments was a Randomized Complete Block (RCBD) with three replications.
The seeds were planted in October 2016; moreover, the lettuce seedlings were transplanted in Novrmber 2016 to the experimental area.
The results referred to the highest total yield (47.863t.ha-1 ) was obtained with treatment T4 followed by treatment T1.
Foliar application of 4.5 ml.L-1 humic acid (T3) recorded significantly highest plant height as compared with control treatment.
In addition the highest values of (TSS) were obtained by soil application (T6) at rate 3.5 ml/L.
The data showed that there were no significant differences in the amount of the N, P, K and nitrate in the lettuce product.
