“…Moreover, Rosa hybrida plants subjected to the treatment with 6-benzyleaminopurine (BAP) showed significant upregulation in the antioxidant enzymes and downregulation in malondialdehyde activity and relative conductivity (Wang et al, 2022). Moringa oleifera is a famous tree known for the antioxidant properties of its leaf extracts (MLE) (Ahmed, 2016). It also comprises various plant growth regulators, such as cytokinins (Yang et al, 2006).…”

This experiment was conducted at the Experimental Farm of Floriculture, Faculty of Agriculture, Assiut University, Assiut, Egypt during the two successive seasons of 2019 and 2020 to study the effect of some natural and synthetic growth stimulants on the growth measurements, percentage and oil yield and photosynthetic pigments of lemongrass (Cymbopogon citratus) plants under water salinity stress. Plants were treated with four growth stimulants (control, Moringa oleifera leaf extract (MLE) at 5% as spray, Bacillus subtilis + arbuscular mycorrhiza fungi as soil drench, benzylaminopurine (BAP) at 100 mg l -1 as pray). Irrigation water salinity treatments were control, 1000, 2000 and 4000 mg l -1 NaCl. The results showed that the higher salinity levels (2000 and 4000 mg l -1 NaCl) caused significant decreases in the morphological characteristics and oil yield, as well as the leaf content of photosynthetic pigments (chlorophyll a, b and carotenoids) of lemongrass plants compared to control and the lowest salinity level (1000 mg l -1 NaCl). The highest salinity level (4000 mg l -1 ) recorded the lowest values of these measurements. Among growth stimulants used, MLE gave the highest values of vegetative growth measurements, percentage and yield of oil/plant and chlorophyll content in fresh leaves, followed by B. subtilis + mycorrhiza fungi. Therefore, the study recommends spraying lemongrass plants with M. oleifera leaf extract at 5% or adding a mixture of B. subtilis with mycorrhizal fungi as natural growth stimulants to obtain the best morphological characteristics, percentage and yield of volatile oil under water salt stress conditions.

“…To improve the productivity and growth of many plants grown in normal conditions, this kind of natural biostimulant has been applied as a foliar application [21][22][23]. To our knowledge, few smallscale experiments have been conducted to investigate the effect of moringa mlant extract on barely crops for productivity [24]. At field scale, no study has been reported using a combined application of moringa (leaf, root, and seed) extract.…”

Under Natural Field Conditions, Exogenous Application of Moringa Organ Water Extract Enhanced the Growth- and Yield-Related Traits of Barley Accessions

Barley (Hordeum vulgare L.) is the preferred crop in arid regions, particularly for farmers with limited agricultural resources and low income. Typically, it is utilized for human consumption, animal feed, and malting. The discovery of natural (organic) sources of biostimulants has attracted a great deal of interest for crop productivity enhancement. Using a randomized complete block design with three main blocks, it was our aim to investigate the effects of foliar moringa (Moringa oleifera L.) organ extract (MOE) on the growth and yield components of a collection of barley accessions grown in Iraq. As indicated by the obtained results, almost all traits associated with barley growth and yield productivity were significantly enhanced by MOE application, relative to the respective control condition. The majority of barley accessions responded positively to the MOE treatment based on all studied traits (with the exception of 1000-kernel weight). According to the results of principal component analysis (PCA), the distribution of accessions on the two components under the MOE application was distinct from the distribution of accessions under control conditions, indicating that accessions responded differently to the MOE application. In addition, the distribution pattern of traits under MOE treatment was comparable to the distribution pattern of traits under the control condition, with the exception of two traits: total yield and 1000-kernel weight. AC5 and AC18 responded positively to the MOE application by possessing the highest total yield and harvest index values. The total yield trait registered the highest increasing value index (37.55%) based on the trait response index, followed by the straw weight (22.29%), tillering number per plant (21.44%), and spike number per plant (21.36%), while the spike length trait registered the lowest increasing value index (0.45%), compared to the traits under control conditions. So far, the results indicate that foliar application of MOE can be utilized effectively as a natural growth promoter to increase the growth and yield productivity of grown barley accessions.
