“…The increased plant height and dry matter production per plant improves the yield components and yield of urdbean (Shweta, 2016). Our finding is accorded with a few previous reports, Yaseen and Hajos [32] reported that the application of moringa leaf extract with the concentration of 10% increased the yield of lettuce and spinach.…”

Blackgram (Vigna mungo L.), the most important pulse crop is grown throughout India. The productivity of blackgram in India is relatively low compared to the world's average productivity. Nowadays for improving productivity foliar spraying of nutrients plays a major role. The available synthetic formulations for foliar spraying are polluting and highly expensive. Hence, the leaf extracts of tropical trees can be utilized as an alternative source since they have enormous bioactive compounds able to stimulate plant growth and improve productivity without any harmful effects. Therefore, the present study was conducted on a sandy loam farm of The Indian Agriculture College, Radhapuram from March 2023 to May 2023 to evaluate the effect of leaf extracts like Moringa oleifera (Moringa), Annona squamosa (Custard apple) and Nerium oleander (Nerium) at different concentration viz., 5% and 10% on cultivation of blackgram crop, variety VBN 8. The results revealed that foliar spraying of Moringa oleifera leaf extract @ 10% + RDF significantly improves the growth components like plant height (27.87 cm and 34.6 cm at 35 DAS and 50 DAS respectively), LAI (2.87 and 4.06 at 35 DAS and 50 DAS respectively), dry matter accumulation (141 g/m2 and 266 g/m2 at 35 DAS and 50 DAS respectively), Crop growth rate (5.77 and 8.33 g/m2/day at 20 to 35 DAS, 35 to 50 DAS respectively), Relative Growth Rate (0.064, 0.042 g/g/day at 20 to 35 DAS, 35 to 50 DAS respectively) and yield attribute like average number of pods per plant (36.9) and seed yield (648 kg/ha) over other treatments and it was on par with RDF + Foliar application of Custard apple leaf extract @ 10%.

“…Several studies explored the potential benefits of MLE on improving tomato productivity. This includes studies by Culver et al [44], Mvumi et al [80,90], Ngcobo and Bertling [47] and Hoque et al [81], which found that MLE significantly increased the plant height, leaf number, number of branches, above-ground dry biomass, dry root mass, fruit yield and quality of tomato. The extracts from fresh moringa leaves influenced tomato productivity by augmenting its leaf lamina thickness, stomatal density, stomatal size and fruit yield [80].…”

“…Other moringa plant parts also contain considerable amounts of phytochemicals, but their use in plant production is not as popular as the use of moringa leaves. Several studies have evaluated the efficacy of MLE on the growth, yield and quality of crops [44][45][46][47], but only a few have analyzed the hormonal profile of the moringa extracts (Table 3). In addition, the concentrations of the main hormone in MLE, zeatin, were found to be a thousand times (from 5-200 µg•g −1 ) higher than the zeatin concentrations in other plant species [16,27,48].…”

“…The extract was then filtered, and the residue was re-soaked with the same solvent amount until the extraction was clear. Organic solvents are the most commonly used method of extracting compounds from moringa plant parts, with many authors adopting this approach [44,45,53,61]. Furthermore, the chemical-based solvents that are commonly used to extract the bioactive compounds in moringa leaf are volatile, leading to a certain percentage of the foliarly applied MLE not being taken up by plants due to evaporation.…”

The extensive use of synthetic chemical fertilizers is associated with environmental pollution and soil degradation. In addition, the high costs of these fertilizers necessitate the search for alternative, eco-friendly and safe natural sources of phytonutrients. The liquid extracted from moringa (Moringa oleifera Lam.) leaves has been used in agriculture to improve the growth and productivity of several crops. The efficacy of moringa leaf extract (MLE) is attributed to its high content of mineral nutrients, protein, vitamins, sugars, fiber, phenolics and free proline. In addition, MLE contains significant amounts of phytohormones, such as auxins, cytokinins and gibberellins. Furthermore, MLE is a valuable product promoting seed germination, plant growth and deeper root development, delaying fruit senescence and increasing the yield and quality of crops grown under normal or stressful conditions. Here, we review the research on MLE as a biostimulant to enhance crop growth and productivity. Moreover, we emphasize its possible introduction to smallholder farming systems to provide phytonutrients, and we further highlight research gaps in the existing knowledge regarding MLE application. Generally, MLE is an inexpensive, sustainable, eco-friendly and natural biostimulant that can be used to improve the growth and productivity attributes of various crops under non-stressful and stressful conditions.

“…Likewise, the greatest vitamin C in citrus was achieved by foliar MLE treatment before flowering as well as at the fruit set stage [65]. Other studies proved that foliar MLE markedly enhanced this compound in grape berry [66], broccoli [67], and lettuce [68]. This may be explained by the fact that MLE is a plentiful source of protein and vitamin C, thereby facilitating better ascorbic acid formation in fruit [57].…”

Assessment of Biostimulant Derived from Moringa Leaf Extract on Growth, Physiology, Yield, and Quality of Green Chili Pepper

With the rapid growth in global population and standards of living, improving food production and quality are the greatest challenges in agriculture. The application of biostimulant derived from moringa leaf extract (MLE) has attracted a great deal of interest to support these efforts in a sustainable approach. A field study was conducted using a randomized complete block design with four replications. The effect of individual and combined application of MLE through seed priming (seed soaking) and foliar spray at different rates (1:30, 1:20, and 1:10, v/v) on growth, physiological, yield, and quality traits of green chili pepper were investigated, which was the aim of this study. In general, the responses generated by the combined MLE methods were more pronounced compared to their single applications. Among all treatments, MLE priming plus foliar spray at 1:30 was effective in improving most traits observed, including chlorophyll fluorescence (6.49%), stomatal conductance (57.19%), plant height (30.57%), leaf number (88.89%), leaf area index (116.67%), fruit weight per plant (46.27%), average fruit weight (39.62%), length (9.89%), diameter (29.65%), firmness (27.77%), and vitamin C content (29.07%) of fruit. Therefore, it is regarded as an appropriate treatment to maximize the potential use of MLE in green chili.
