“…Abdalla [111] reported that moringa leaf extracts increased vegetative growth, chlorophyll content, total sugars, phenols, ascorbic acid, and photosynthetic rate of rocket salad. Similar effects have been observed in fennel [112,113] and squash under water stress condition (plants under a deficit irrigation of 80% or 60% ETc) [114]. In tomato plants it led to a greater fruit weight, volume and firmness, and enhanced titratableacidity, chlorophyll and ascorbic acid content [115].…”

Abiotic stresses strongly affect plant growth, development, and quality of production; final crop yield can be really compromised if stress occurs in plants’ most sensitive phenological phases. Additionally, the increase of crop stress tolerance through genetic improvements requires long breeding programmes and different cultivation environments for crop performance validation. Biostimulants have been proposed as agronomic tools to counteract abiotic stress. Indeed, these products containing bioactive molecules have a beneficial effect on plants and improve their capability to face adverse environmental conditions, acting on primary or secondary metabolism. Many companies are investing in new biostimulant products development and in the identification of the most effective bioactive molecules contained in different kinds of extracts, able to elicit specific plant responses against abiotic stresses. Most of these compounds are unknown and their characterization in term of composition is almost impossible; therefore, they could be classified on the basis of their role in plants. Biostimulants have been generally applied to high-value crops like fruits and vegetables; thus, in this review, we examine and summarise literature on their use on vegetable crops, focusing on their application to counteract the most common environmental stresses.

“…This phenomenon has the especially important function of protecting the plant from overheating. Moringa oleifera leaf extract increased the surface area of the Cucurbita pepo L. by 9.7% and simultaneously led to a 34.6% increase in the chlorophyll content of the leaves compared to the control [50]. The positive effect of the A. nodosum extract in a period of drought on the growth of spinach has been proven.…”

“…The peptides and amino acids contained in these formulations demonstrated a protective action against excessively high temperatures in the summer season and induced root growth and development, while vitamins and humic acids resulted in fruit growth [49]. Horseradish extract increased pumpkin yield by 12.5% [50] and the beneficial effect of fungal species Glomus intraradices and Trichoderma atroviride positively influenced the yielding of zucchini, resulting in a yield increase of 0.39 kg per plant on average, probably by increasing the effectiveness of nutrients uptake [14]. A 3% Moringa oleifera extract in combination with 0.6% ZnSO 4 and 0.25% K 2 SO 4 increased the yield of "Kinnow" mandarin plants by 65% (Table 2) compared to the control [51].…”

“…It should be emphasized that the increased mechanical strength or fruit colour change results from the good condition of fruit plants, which in turn is a result of their proper nutrition [50]. Biostimulants are supplied externally, which indirectly, e.g., induced by the photosynthesis process, plays an important role in the nutrition of plants.…”

Plant Biostimulants: Importance of the Quality and Yield of Horticultural Crops and the Improvement of Plant Tolerance to Abiotic Stress—A Review

Biostimulants are among the natural preparations that improve the general health, vitality, and growth of plants and protect them against infections. They can be successfully used in both agri- and horticultural crops. The main active substances used in such preparations are humic and fulvic acids, protein hydrolysates, compounds containing nitrogen, seaweed extracts, beneficial fungi, and bacteria. Biostimulant formulations may be single- or multi-component, but the synergic action of several different components has been observed. Many groups of biostimulants have been distinguished through their method of application (soil, foliar), the material from which they were produced (plant, animal), or the process by which they were created (hydrolysis, fermentation, extraction). Natural soil stimulants can induce the development of beneficial soil organisms that provide substrates for plant growth. The use of natural preparations that are not harmful to the environment is particularly important in connection with the progressive processes of soil degradation and atmospheric pollution. This review gives an overview of the importance and influence of different natural plant biostimulants on both the yield and quality of crops.

“…Moreover, several re-searches have indicated that M. oleifera Lam (family: Moringaceae) is a highly valued plant with multipurpose effects. Moringa oleifera as a novel natural biostimulant for plant growth, could play a role in improving drought tolerance in plants under saline condition [1,11]. The tree ranges in height from 5 to 10 m. It is found wild and cultivated in many countries of the tropics and subtropics [12,3].…”

Abstract. The use of Moringa oleifera leaves extract as plant growth hormone on cowpea plant (Vigna unguiculata) has been studied at the biological garden of Usmanu Danfodiyo university, Sokoto. An extract was made by grinding young moringa leaves and diluted with water at the ratio of 1:30 25 mls, three blocks were made labelled M, F and D, with three replications each, the extract prepared was applied on block 'M' only, while a small pinch of synthetic fertilizer (Urea) was applied in block 'F' and a control treatment was set up using distilled water, which applied to each plant in hill D. results indicates that in the 3 rd week of observation the cowpea plants treated with moringa extract have the highest mean of stems, number of leaves and branches, length of leaves and branches, and thickness of stem. Then followed by those treated fertilizer mean and finally those treated with distilled water this result shows that moringa leaves extract has an improving effects on the growth of cowpea. Moringa leaf extract (MLE) is rich with numerous growth hormones, particularly zeatin that has been reported to increase the crops yield in the range of 10-45 %. Moringa leaf juice also contains micronutrients in sufficient quantities and suitable proportions that increase the growth, yield components and yield of a variety of crops.
