“…The foliar application at a higher rate (10g/L) of moringa leaf extract ranked the first followed by 5g/L of moringa leaf extract for improving vegetative growth characteristics of the lettuce plant and its yield. Similar results were stated by [37,38] on lettuce, [22,26,31] on common beans and [24,29,39] on tomatoes.…”

Lettuce is an important leafy vegetable crop, which contains many essential elements and vitamins for human health. The field experiments were conducted at the experimental station of the National Research Centre, Nobaria, Beheira Governorate, (Egypt) during the cultivation seasons of 2020/2021 and 2021/2022 to evaluate lettuce productivity (cv. Balady) using moringa seed cake as natural nutrients source comparing with other organic fertilizer (vermicompost) and chemical fertilizer (Ammonium sulfate) as well as a foliar application at two concentrations (5 and 10 g/L) of moringa leaf extract compared to untreated control. The obtained results showed positive effects for soil fertilizer application of moringa seed cake treatment on vegetative characters, i.e., fresh weight (g/plant) and leaf neck width (cm) as well as chemical contents, i.e., dry matter (%) and nitrate content (mg/kg). Moringa seed cake treatment recorded the same value as Ammonium sulfate treatment on their effects on plant height, leaf width and N, P and K content. The foliar application of moringa leaf extract at a higher rate (10g/L) ranked first followed by the rate of 5g/L for improving the vegetative growth characteristics of the lettuce plant and its chemical contents. Concerning the interaction treatments between soil additions and foliar applications of moringa leaf extract, the highest values of fresh weight, plant height, leaf length, leaf width and leaf neck width leaf dry matter, chlorophyll content and macronutrients (NPK) as well as the lowest value of nitrate content were resulted from fertilized lettuce with moringa seed cake and foliar spraying with a higher rate (10g/L) of moringa leaf extract.

“…In this study, Moringa leaf and its stems, and petioles as extracts were used in comparison with others kind of fertilizers. The increase in plant performances and yield of mustard green by foliar application of bio-foliar moringa may be presence of higher nutrients as evident from Yaseen and Hájos (2021) in lettuce cultivar.…”

“…Besides, nitrate accumulation in vegetables depends on the amount and kind of nutrients present in the soil and is closely related to the time of application, the amount and composition of the fertilizers applied (Zhong et al 2002;Huang et al 2010;Qiu et al 2014). Yaseen and Hájos (2021) reported that foliar application of moringa leaf extract (6%) reduced the leaf nitrate content by 16-44% in lettuce. Some other studies with application of biostimulants as double irrigation with 1.0% Bio-algeen S-90 (200 mL per plant) extracted from the brown seaweed and 0.3% Megagreen (100 mL m -2 ) reduced nitrate content in lettuce leaves (Dudaš et al 2016).…”

Background: Moringa oleifera is a vegetable widely consumed because of its nutritional benefits such as proteins, vitamins minerals, antioxidant compounds, and vitamin E. While the plant leaves have been utilized to produce organic fertilizer or bio-extract, other parts such as stems, branches, or leaf petioles have often been discarded as waste. Methods: The present study evaluated different ratios (1:10; 1:20; 1:30; 1:40 and 1:50) and types of bio-foliar fertilizers (Moringa bio-foliar fertilizer, chitosan, and seaweed fertilizers) on yield, and quality in mustard green. The pot and field experiments were conducted in the spring seasons of 2019 and 2020 in completely randomized design using three replications. Result: The results showed that the mustard green yield and quality were affected by ratio and type of bio-foliar fertilizer in both seasons. Highest yield and quality was found for application of moringa bio-foliar fertilizer. The nitrate accumulation value (147.3 mg kg-1) found were also higher for moringa bio-foliar fertilizer but lower than the standard threshold. A strong relationship was found between economic yield (R2 = 0.82 to 0.95 in pots and field experiment (R2 = 0.78 to 0.81). In conclusion, moringa bio-foliar fertilizer at spraying ratio of 1:10 can be used to achieve higher yield and quality for mustard green.

“…Chlorophyll and carotenoids are light-harvesting pigments that play vital physiological functions in all photosynthetic organisms [56]. Many research studies had shown the positive role of MLE in improving chlorophyll and carotenoid content in diferent plants as in rice (Oryza sativa L.) under water stress conditions [57], peppers [16], fennel plants [58], SPAD value in lettuce [13,14], and common bean (Phaseolus vulgaris L.) [59,60].…”

“…Biostimulants, especially moringa leaf extract from the moringa tree (Moringa oleifera Lam. ), are among the suggestions that have been practiced not only to reduce the amount of fertilizer used but also to improve the quality of many vegetables [11], such as lettuce (Lactuca sativa L.) [12][13][14], tomatoes (Solanum lycopersicum) [15], peppers (Capsicum annuum) [16], cabbage (Brassica oleracea var. capitata) [17], onions (Allium cepa L.) [18,19], and squash (Cucurbita pepo L.)

Moringa leaves contain a proper amount of antioxidants, amino acids, vitamins, hormones, macronutrients, and micronutrients. Therefore, it is applied as a natural, inexpensive, and simple-to-make biostimulant to boost nutritional value and growth parameters in a variety of plants. The main purpose of this study is to determine the optimal concentration of Moringa oleifera L. leaf extract (MLE) as an effective biostimulant to improve nutritional and physical quality in cabbage (Brassica oleracea var. capitata). To do this, three concentrations of MLE (6, 8, and 10%) were foliar sprayed to the plant leaves at a rate of 25 mL plant−1 for every two weeks from transplantation till harvest, while control plants (Ø) were sprayed with distilled water only. Our results show that MLE greatly increased cabbage growth, nutrient content, pigment content, and nutrient absorption, while a high concentration of 10% MLE could also significantly reduce nitrate content in cabbage leaves. In comparison to the control plants, sprays of 6%, 8%, and 10% MLE reduced nitrate content by 23%, 14%, and 12%, respectively. However, the lowest nitrate content was found for the plants sprayed with 6% MLE. Except for the dry matter, all the growth parameters, mineral content, and pigment content were significantly higher after spraying with 10% MLE, while better vitamin C and lower nitrate were found in the plants treated with 6% MLE. A Pearson correlation reveals that head weight has a positive correlation with head diameter, head height, chlorophyll a, and carotenoids at p levels of 0.01 and a positive correlation with chlorophyll b and vitamin C at p levels of 0.05. Vitamin C and dry matter, on the other hand, had a negative connection with nitrate content.
