ABSTRACT: A field trial was implemented at the research center field at general directorate of agriculture, Dohuk Governorate, Iraqi Kurdistan region in summer season of (2022-2023) to find out the impact of foliar application of humic acid at three levels (0, 2, and 4) ml L-1 and Maxigrow (an organic fertilizer) with three levels (0, 1, and 2) ml L-1 and their combinations on outgrowth, flowering and harvest of local snake cucumber. The experiment was organized following a randomized complete block design (RCBD) including three replicates. The data displayed that the individual dose of humic acid at (4) ml.L-1 significantly enhanced foliage traits number of branches, stem diameter (cm), Leaf area (cm2), plant fresh weight (g), and chlorophyll content (SPAD) as well as increased flowering characters number of flowers after 30 days and number of flowers after 40 days and yielded components fruit length (cm), fruit diameter (cm), and total yield (ton.ha-1). The same profound effect was exhibited by the singular dose of Maxigrow at concentration (2) ml.L-1. However, the highest mean values were produced from humic acid at concentration (4) ml.L-1 in combination with Maxigrow at concentration (2) ml.L-1 in comparison with control. The increased level of humic acid and Maxigrow is advised for organic productivity of local snake cucumber.
