Effect of moringa leaf extract and nano fertilizer on the chemical and vegetative characteristics of local citrus lemon
Abstract
Citrus lemon, is one of the most important fruit crops with varied uses. At the age of one year, 144 uniform seedlings were taken. In the experiment, four levels of Moringa leaf extract were sprayed: M0 (distilled water), M1 (100ml.L-1), M2 (150ml.L-1), and M3 (200ml.L-1). Additionally, four levels of Nano-fertilizer were also sprayed: N0 (distilled water), N1 (5mg.L-1), N2 (10mg.L-1), and N3 (15mg.L-1).The results demonstrated that the highest averages for the investigated vegetative traits (seedling height, number of leaves, stem diameter, and total number of branches per seedling) were for the N3 spray treatment of Nano fertiliser , reaching 16.70 cm, 247.42 leaves, 3.65 mm, and 7.35 branch respectively. Likewise, there was a significant improvement in the chemical characteristics such as (chlorophyll content, nitrogen, phosphorus, and potassium), reaching 47.55 mm 100 g-1 fresh weight, 1.7%, 0.31% and 2.65% respectively. The highest averages for the investigated vegetative parameters (seedling height, leaves number, stem diameter, and total Branches number) were obtained for the M3 spray treatment (200 ml.L-1) of Moringa leaf extract, reaching 16.18 cm, 3.65 mm, and 7.35 branches, respectively. While across a number of measured traits, the interaction treatment N3M3 gave the highest results. Additionally, the chlorophyll, nitrogen, phosphorus, and potassium contents in the leaves increased significantly. These results can beused in future for other fruit trees, not just for the citrus family.
