Abstract

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).

本试验于2020-2021年生长季在Al- muthanna农业学院/ Al Bandar第二研究站(Al Bandar)的一个大棚进行，研究了添加腐植酸(腐植酸钾)(0、5.0、10.0、15.0 g L-1)和叶面施用3种浓度(0、5.0、10.0 g L-1)酵母悬浮液对滴灌温室茄子(Solanum melongena L. Barcelona var.)的影响。采用随机完全区组设计(RCBD)进行因子试验，共3个重复。均数比较以最小显著差异(LSD)为基础，概率为0.05。结果表明，腐植酸和酵母悬浮液及其相互作用对所研究的各试验性状(N %、叶绿素指数(SPAD)、TSS %果实、叶面积、株高、枝号和分枝数)均有显著正影响。结果表明，腐植酸浓度为15.0 g L-1和酵母悬浮液浓度为10.0 g L-1时，腐植酸浓度分别为6.42%、66.69 SPAD、15.21%、49.30 dm2、95.77 cm、5.79、758.50 g，其产量最高。
