Moringa Leaf Extract

AbstractThe history of plants to be utilized as medicines is thousands of years old. Black cumin is one of the most widely examined plant possessing naturally occurring compounds with antimicrobial potential. Foliar application of growth stimulators is a successful strategy to enhance yield and quality in many crops. A field study was planned to apply growth stimulator like moringa leaf extract on black cumin crop grown under field conditions using RCB design with three replications. All other agronomic inputs and practices were uniform. The treatments were moringa leaf extract concentrations (10%, 20%), growth stages (40 days after sowing, 80 DAS, 120 DAS, 40 + 80 DAS, 40 + 120 DAS, 80 + 120 DAS, 40 + 80 + 120 days after sowing) and two controls unsprayed check (i.e. no moringa leaf extract, no water) and sprayed check (no moringa leaf extract + water). Application of 20% moringa leaf extract at stage-7 (40 + 80 + 120 days after sowing) had significantly increased plant height, branches plant−1, essential oil content, fixed oil content, peroxidase value and iodine value of black cumin oil over unsprayed control. Application of moringa leaf extract showed maximum results and improves growth and yield of black cumin when applied at 40 + 80 + 120 days after sowing. As this study was only conducted using moringa leaf extract, it is advisable to conduct an experiment with various bio stimulants along with fertilizer combinations and growth regulators to check their synergistic effects for more reliable and acceptable recommendations in future.

Moringa Leaf Extract

Moringa oleifera leaf extract has a potential effect as a growth enhancer of many crops. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the effect of foliar application of moringa leaf extract on growth and yield of late sown wheat (BARI Gom-26). The experiment was laid out in a randomized complete block design with six treatments and three replications. The treatments were T1 (Control), T2 [moringa leaf extract (MLE) sprayed only at tillering stage], T3 (MLE sprayed at tillering and jointing stages), T4 (MLE sprayed at tillering, jointing and booting stages), T5 (MLE sprayed at tillering, jointing, booting and heading stages), and T6 (MLE sprayed only at heading stage). Application of moringa leaf extract significantly increased the growth and yield attributes as well as grain and straw yield of wheat. Among various treatments with moringa leaf extract the performance of T4 (MLE sprayed at tillering, jointing and booting stages) was the best as it produced the tallest plant (87.87 cm), the highest fresh and dry weight of root (16.51 g and 11.37 g respectively), the highest number of spikelets spike-1 (19.70) and filled grains spike-1 (45.53), as well as the highest grain and straw yield (3.62 t ha-1 and 5.43 t ha-1 respectively) of wheat. Therefore, moringa leaf extract as a foliar spray can be applied at critical growth stages to increase the growth and yield potentiality of late sown wheat.Asian J. Med. Biol. Res.

With increasing population, the demand for food is also increasing. So, with the aim to increase the productivity of crop a field experiment was conducted to determine the effectiveness of the foliar application of moringa leaf extract (MLE) at growth and yield of sunflower under water deficit conditions at Agronomy research area, Bahauddin Zakariya University, Multan. The treatments comprise of Factor A: Irrigation,(I0 = Normal irrigation, I1 = Skipped at knee height stage, I2 = Skipped at knee height + heading stage, I3 = Skipped at knee height + heading + seed development stage and Factor B: Foliar application of MLE (Subplot), T0 = No spray, T1 = Spray at knee height stage, T2 = Spray at knee height + heading stage, T3 = Spray at knee height + heading + seed development stage with randomized complete block design (RCBD) split-plot design in three replications. The interactive effect between moringa leaf extract (MLE) and irrigation was significant. Maximum head diameter (22.17cm), number of achenes per head (1030.30), 1000-achenes weight (49.73g), achene yield (3474 kg/ha), and biological yield (10729.83 kg/ha), oil content (41.734%), protein content (20.8%) was observed in F3 (K+H+S) and I0 (Normal) irrigation. While minimum head diameter (15.57cm), number of achenes per head (681.67), 1000-achenes weight (42.001g), achene yield (2536.33 kg/ha), and biological yield (8209.33 kg/ha), oil content (36.3%), protein content (16.27%) was observed in F0 (no spray) and I3 (K+H+S) irrigation. Results showed that foliar application of moringa leaf extract under normal conditions boost the crop yield and drought stress at (K+H+S) is detrimental for growth and development of sunflower.

Moringa Leaf Extract

Moringa (Moringa oleifera L.) leaf extract is a natural plant growth stimulant that is well-known for its ability to improve plant growth and development. A field study was conducted to evaluate the influence of MLE (Moringa Leaf Extract) on the growth, yield and nutritional improvement in two vegetable crops [Tomato (Solanum lycopersicum) and Indian Spinach (Basella alba)]. The extract was applied at two weeks interval with different frequencies. The crops were fertilized with chemical fertilizers and MLE application was done as per treatment @ 25 ml/plant. For each of the crops, this bio-stimulant had a significant boosting effect on growth, yield and nutrient uptake whereas the maximum frequency in the application i.e. T4 (foliar application of MLE at 2 weeks after transplanting and application at every 2 weeks thereafter) showed the highest influence. Indian Spinach responded proportionally more to foliar-applied MLE in terms of plant growth and nutrient uptake compared to tomato. The effect of MLE on the yield parameters was more pronounced in tomato that showed a 25% (averaged across all the growth parameters) increase over control, but Indian Spinach showed ~20% increase in yield parameters compared to control. Therefore, applying MLE to the foliage may assist in increasing the yield by improving plant growth across the different vegetable species (e.g., Tomato and Indian Spinach).

Moringa Leaf Extract

 Studying the use of natural extracts or biostimulants in improving vegetable plants is the current needs as an alternative way to the use of chemical products. This experiment was carried out to evaluate the effect of Moringa oleifera leaf extract (MLE) as a natural growth regulator on bulb diameter, weight and yield of onions ‘Texas Early White’ cultivar. Therefore, three concentrations (control, 2%, 4% and 6%) of MLE and three different onion set sizes [small (3±1 g/set), medium (6±1 g/set), and large (10±1 g/set)] were prepared in a randomized complete block design with three replications and plant spacing 20×15 cm. MLE was applied as a foliar spray directly onto the plants with the amount of 25 ml/plant every two weeks from sprouting to maturity. The achieved results indicate that the interaction of foliar spray with moringa leaf extract 4% and large set size of 10±1 g/set gave the highest value of the total yield 4802.7 g m-2, while the lowest yield 1531 g m-2 was recorded in the interaction of control and the smallest set size of 3±1 g/set. Also, a significant difference was recorded in bulb diameter separately. Thus, the largest bulb diameter 68.90 mm was obtained from the planting of the largest set size 10±1 g/set with 4% of MLE while the smallest bulb diameter 38.40 mm was recorded from the smallest set size 3 ±1 g/set with control treatment. Similarly, a significant effect was recorded in both set size and MLE separately. The highest bulb diameter 58.71 mm was achieved in the planting of the largest sets 10±1 g/set, while the lowest diameter was 42.12 mm in the planting of the smallest set size 3 ±1 g/set. Similar results were recorded for the bulb weight and total yield. The concentration of 4% MLE produced the highest bulb weight 99.74 g/bulb and yield 3324.5 g m-2, while the lowest bulb weight and yield was obtained in the control treatment 55.61 g/bulb, and 1869.3 g m-2. Consequently, the results indicate the positive effect of Moringa leaf extract which can be applied as a natural substance in the form of foliar spray at critical growth stages to improve the growth and yield of dry onions.

Moringa Oleifera Lam

Natural biostimulants obtained by plants are intensively used nowadays to improve crop yield and quality. The current study aimed to evaluate the effects of leaf extract of moringa (Moringa oleifera Lam.) (MLE) in modifying baby leaf characteristics of two genotypes of Brassica. The trial was started in October 2020 in a greenhouse; a cultivar of kale ‘Cavolo Laciniato Nero di Toscana’ (CL) and a Sicilian landrace of sprouting broccoli ‘Broccoli Nero’ (BN) were used. The plants, after 15, 30 and 40 days from sowing, were treated with MLE, while the control plants (C) with distilled water. Treatment with MLE modified morphological and nutritional value, but with different behavior in the two genotypes. In fact, in BN the treatment reduced the antioxidant activity (2.2-diphenyl-1-picrylhydrazyl (DPPH)) by 54%, while in CL the treatment increased this parameter by 40%. For the phenolic concentration and the sugar content the values recorded were significantly increased by MLE compared to control plants in CL, where in BN a significant reduction was registered. The CL plants treated with MLE showed a significant reduction (−70%) in nitrate content compared to the control plants; a negative effect was, instead, observed in BN, where the plants treated with moringa showed an increase of 60%. Results of this study showed how the foliar application of MLE was effective in improving various nutraceutical parameters, in particular in kale, because it appears to be a species-specific response.
