الملخص EN

This experiment was conducted during grown season 2020-2021 in one of greenhouses in the second research station (Al Bandar) of the College of Agriculture / University of Al-Muthanna, to study the effect of adding humic acid (potassium humate) (0, 5.0, 10.0, 15.0 g L-1) and Foliar application of yeast suspension at three concentrations(0, 5.0, 10.0 g L-1) on eggplant (Solanum melongena L.

Barcelona var.

), Plants grown in greenhouses under a drip irrigation system.

A factorial experiment was carried out according to a randomized complete block design (RCBD) with three replications.

Means were compared based on least significant differences (LSD) at 0.05 of probability.

The results showed a positive significant effect of each of humic acid and yeast suspension and their interactions in all experimental characteristics under study (N % , Chlorophyll Index (SPAD), TSS % Fruit, Leaf Area, Plant Hight, Branch No.

, Early Yield), as the results showed that adding humic acid at a concentration of 15.0 g L-1 and yeast suspension at a concentration of 10.0 g L-1 gave the highest values (6.42 % , 66.69 SPAD, 15.21 % , 49.30 dm2 plant-1, 95.77 cm, 5.79, 758.50 g).
