Moringa Oleifera extract use as bio-fertilizer during drought.
A biofertilizer (also bio-fertilizer) is a substance which contains living microorganisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. An extract is a substance made by extracting a part of a raw material.
Moringa leaves extracts can be used to alleviate the adverse effect of water deficit stress. Research has shown that Moringa Oleifera leaves extract offers a solution.
In dry areas, agriculture is a recurrent problem, water!
Without water, no, low or bad harvest!
Drought caused significant decreases in growth parameters (shoot and root length, fresh and dry weight of shoots and roots) and photosynthetic pigments (chlorophyll a, chlorophyll b, carotenoids and total pigments).
Drought is abiotic stress limiting factors of plant growth and yields thus negatively affect production of over 25% of world agriculture. Deficit of soil water caused significant reduction in photochemical activities in some plants, reduction in the activities of enzymes responsible for some processes like respiration, translocation, hormone balance, macro and micro nutrients uptake and metabolism (Rohbakhsh, 2013).
Moringa leaf extract (MLE 30) could trigger the activation of physiological compounds persist in plants to alleviate the oxidative damage causing by drought, leading to improvements in physiological and biochemical aspects for the plant growth under drought conditions.
Moringa oleifera leaves extract (MLE) is the most natural plant growth enhancer, has no cost and enhance the tolerance of plants under different environmental conditions like drought. Drought stress has destructive effect on the content of cytokinin in plant. On the other hand, the high level of zeatin makes Moringa leaves extract (MLE) more effective as a natural compound promoting plant tolerance under stress conditions (Zaki & Rady, 2015).
Inorganic ions such as nitrogen (N), phosphorus (P), potassium (K) have important roles in plant mechanisms. The decline in soil water actually reduces nutrient ions uptake and nutrient transport in plants (Sardans & Penuelas, 2012).The inhibition in nutrient uptake by plants under water stress is related to reduction in transpiration process, impaired active transport and membrane permeability (Tanguilig et al., 1987).
Leaf extract of Moringa Oleifera plants has been reported to be a rich source of many minerals such as Ca, P, Na, Mg, K, Fe and others that can be valorized for nutrition balance in plants (Moyo et al., 2011).
Moringa leaf extract fertilization. Sivakumar & Ponnusami (2011) realized the increased uptake and accumulations of some nutritive elements as N, K, Ca, Mg and P as well as Fe in roots and shoots of several plants by using Moringa leaf extract. MLE is supposed to accelerate the nutrient uptake and translocation through the plant by increasing the root membranes permeability for electrolytes, preventing nutrients fixation and increasing its mobility in soil.
Results presented in Table, showed that, plant growth parameters (shoot and root length, fresh and dry weights of shoots and roots) of drought stressed Glycine max plants were affected. Data showed that the effect of drought on plant increased according to decreased water hold capacity (60% and 40% hold water capacity). It was decreased significantly with increasing drought stress as compared with control plants. Further, spraying Moringa Oleifera leaf extract (MLE30) alone caused a noticeable improvement in all of mentioned growth parameters compared to untreated plants, indicating the higher efficiency of growth, development in the presence of (MLE30) supplementation.
Conclusion: The present results suggest that Moringa leaf extract (MLE 30) could trigger the activation of physiological compounds persist in plants to alleviate the oxidative damage causing by drought, leading to improvements in physiological and biochemical aspects for the plant growth under drought conditions. Moringa leaves extracts can be used to alleviate the adverse effect of water deficit stress.
