Abstract

Field trials were performed to investigate the effects of humic acid (HA) and multinutrient foliar fertilizer “Micro Power” (MP) coupled with farmer’s practices ( FP ), addressed in single and/or split dose frames at different plant phenological stages on various vegetative, reproductive, and physiological attributes of citrus trees (Citrus reticulata cv. kinnow mandarin). The results exhibited a profound response of treatments on various growth parameters (32.5% increase in plant height, 22.2% increase in fruit set branch−1, 5.25% decrease in fruit drop percentage, 89.81% increase in fruit yield (kg), etc.) of citrus trees when compared to the control (FP). Likewise, a significant positive response was observed regarding various plant physiological parameters (leaf nutrients, total chlorophyll content, etc.) and physicochemical characteristics (ascorbic acid, total sugars, etc.) of citrus fruits. This study confirmed the reproducibility of HA and MP applications to improve the yield/quality of citrus and can lead to an organically sustainable citriculture.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
