IMPORTANCE OF COMPOST FERTILIZATION AND SPRAYING WITH MORINGA LEAF EXTRACT ON YIELD AND QUALITY OF CHERRY TOMATO UNDER ORGANIC SOILLESS SYSTEM

Growth-promoting properties of moringa (Moringa oleifera) leaves were investigated for potential use in crop production by comparing the efficacy of bimonthly foliar and root applications of a moringa leaf extract [MLE (3.3% w/v)] with the cytokinins 6-benzyladenine (6-BA) and trans-zeatin (t-Z), each at 25 mg·L−1, to increase plant growth, flowering, yield, fruit size, and fruit quality of ‘Super Sweet 100’ cherry tomato (Solanum lycopersicum). Foliar-applied t-Z and root-applied MLE increased canopy biomass (P ≤ 0.01) and root- and foliar-applied MLE increased lateral vegetative shoot number (P ≤ 0.001) and plant height (P ≤ 0.001) relative to untreated control plants. Only foliar-applied MLE increased floral shoot number compared with untreated control plants (P ≤ 0.001). Plants in all treatments, except root-applied 6-BA, produced more flowers than untreated control plants (P ≤ 0.001). Plants receiving root-applied t-Z produced the greatest number of flowers followed by plants receiving root-applied MLE. Cherry tomato plants treated with root-applied t-Z or MLE produced the greatest number of fruit per plant and significantly more than untreated control plants (P ≤ 0.001). Foliar-applied 6-BA and MLE and root-applied t-Z and MLE increased yield as grams of fruit per plant compared with the untreated control (P ≤ 0.01). Foliar- and root-applied MLE increased fruit concentrations of soluble sugars (P ≤ 0.001), protein (P ≤ 0.001), antioxidants (P ≤ 0.001), and lycopene (P ≤ 0.001) compared with fruit from untreated control plants. Foliar- and/or root-applied MLE resulted in the greatest leaf concentrations of protein (P ≤ 0.01), proline (P ≤ 0.01), arginine (P ≤ 0.01), and total antioxidants (P ≤ 0.05), which were all significantly greater than the concentrations in leaves from untreated control plants. The results of this single experiment provide evidence suggesting that MLE warrants further research as an inexpensive growth promoter for enhancing tomato plant biomass, yield, and fruit quality, especially in organic crop production, which prohibits the use of many commercial synthetic plant growth regulators.

"A field experiment was carried out during autumn season of 2019 to study the effect of combination of mineral fertilizers, moringa leaf extract and tryptophan acid on yield and quality of three synthetic varieties of maize and the possibility of replacing part of the mineral fertilizers with these organic maters.The experiment included three synthetic varieties of maize (bohooth-5018, Baghdad-3 and Sumer) in the main plots and five fertilizer treatments(application mineral fertilizer as recommended, application 50% of mineral fertilizer + spraying moringa leaf extract at 3% , application 50% mineral fertilizer + spraying moringa leaf extract at 6% , application 50% mineral fertilizer + tryptophan acid at 50 ppm and application 50% mineral fertilizer + tryptophan acid at 100 ppm ) in the sub plots. The results showed that maize varieties had no-significant difference in all studied characters. Application 50% mineral fertilizer + spraying moringa leaf extract at 6% gave the highest grain yield(8.732 tan ha-1) and all its components (number of ears per plant, number of rows per ear, number of grains per row) and oil percentage (10.72%).While application 50% mineral fertilizer + tryptophan acid at 100 ppm was superior in weight of 500 grains (108.89 g) and protein percentage (3.91%)."

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.
