Effect of foliar application of moringa (<i>Moringa oleifera</i>) leaf extract with recommended fertilizer on growth and yield of okra (<i>Abelmoschus esculentus</i>)

Abstract

to study the effects of different concentrations and frequencies of Moringa (Moringa oleifera) Leaf Extract (MLE) as a foliar application on growth and yield of okra (Abelmoschus esculentus) plants. This experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates with the following treatments; T0control (Distilled water), T1-10% MLE at once a week interval, T2-10% MLE at once in two weeks interval, T3-20% MLE at once a week interval, T4-20% MLE at once in two weeks interval, T5-30% MLE at once a week interval and T6-30% MLE at once in two weeks interval. Foliar application of MLE was initiated at two weeks after germination and each plant is sprayed with 25 ml of MLE and the growth performance was recorded at 4, 6 and 7 WAP. The results showed that foliar application of MLE had a significant (p < 0.05) effects on tested parameters of okra over the control at all growth stages. MLE with 10% of the foliar application at once a week interval increased plant height, number of branches/plant, number of leaves/plant, leaf area index, dry weight of leaves, stems, roots, total biomass, number of pods/ha and dry weight of pods. The results suggest that under the conditions in the experiment, yield could be increased by threefold using MLE at 10%. The use of Moringa leaf extract as a plant growth booster is inexpensive, environmentally safe and low-cost technology to improve the yields by the small farmers.

Improving growth and productivity of Cordia africana trees using moringa leaf juice in north western Ethiopia

“…The highest values for plant height (65.07 cm) and RCD of (1.63 cm) (Table 1) were recorded in treatment of 50 ml EM (application of 50 ml moringa leaf extract on emergence stage). The lowest values for plant height (52.69 cm and 54.39 cm) and with RCD of (0.35 cm and 0.47 cm) (Figure 2) in the treatment of application of 25 ml and 50 ml moringa leaf extract 30 days before transplanting to the field and control, respectively and same result was also reported by Kanchani and Harris (2019). Application of moringa leaf extract with high concentration in the early stage of Cordia africana tree enhances the growth as well as diameter, but there is no effect when the extract was applied in the latter stage of the tree in the nursery.…”

“…Similar researches was reported by Biswas et al (2016) on maize, Culver et al (2012) on tomatoes and Mvumi et al (2012) on beans and maize. This might be due to zeatin, which is the most common cytokinin in the extract, responsible for the improved plant height at an early growth (Kanchani & Harris, 2019…”

Exogenous application of moringa leaf extract influences growth, flowering and vase life of snap dragon (Antirrhinum majus) cultivars

“…Minimum numbers of leaves plant -1 (91.67) were produced by control (0%) treatment. It is obvious from the results that snapdragon These findings also agree with[24] who reported that MLE at the rate of 10 % concentration increased the number of leaves plant -1 in okra. Similar findings were reported by[25] in sweet corn and[26] in garlic.…”

Moringa oleifera Leaf Extract Enhanced Growth, Yield, and Silybin Content While Mitigating Salt-Induced Adverse Effects on the Growth of Silybum marianum

“…The moringa leaf extract (MLE) has been classified as one of the prominent bio-stimulants due to its rich minerals, free amino acids, vitamins, phytohormones, and antioxidant contents [12]. Moreover, the preparation of MLE in 80% ethanol or in water is both cost-efficient and eco-friendly [12]; therefore, it has been used as a natural growth promoter and/or stress-reducing agent for many plant species [12][13][14][15][16][17][18].…”
