The Use of Moringa Leaves Extract as a Plant Growth Hormone on Cowpea (Vigna Anguiculata)

Abstract

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.

Exogenous application of moringa leaf extract influences growth, flowering and vase life of snap dragon (Antirrhinum majus) cultivars

“…The days were counted from time when the spike was kept in the vase. When 5o% of the florets were wilted the vase, life was considered terminated [ The results are also in line with the findings of [27] who reported that MLE at the ratio of 1: 30 resulted an increase in growth parameters of cowpea. [28] also reported an increase in growth and yield of tomato by foliar spray of MLE at the ratio of 1:32.…”

Effect of foliar application of moringa (<i>Moringa oleifera</i>) leaf extract with recommended fertilizer on growth and yield of okra (<i>Abelmoschus esculentus</i>)

“…Zeatin is a growth promoting hormone which is present in the MLE promotes the growth of lateral buds and that in turn increase the number of branches. In okra, foliar application of MLE increased the number of branches with the extract after pounding the 100g of Moringa leaves in 8 liters of water (Anyaegbu, 2015), in cowpea with 1:30 dilution (Maishanu et al, 2017) and in tomato with 100 % (Bashir et al, 2014). However, in this experiment, the concentration at 10 % was 10 times lesser than that of Bashir et al (2014).…”

The Impact of Bio-Stimulants on Cd-Stressed Wheat (Triticum aestivum L.): Insights Into Growth, Chlorophyll Fluorescence, Cd Accumulation, and Osmolyte Regulation

“…Previous researchers found that the Cd in wheat is taken up through roots and then translocated to the aerial parts, thus, interfering with major metabolic processes to hinder normal growth and reproduction activities (Abedi and Mojiri, 2020). The photosynthetic processes are the chief modulators for the growth and development of plants (Maishanu et al, 2017). An elevated level of Cd in the rhizosphere imposed severe phytotoxic effects in plant tissues (Riaz et al, 2021b), which replicate itself by hampering plant's morphological, physiological, and biochemical processes (Wali et al, 2015), like destroying the leaf chlorophyll structure to deteriorate photosynthetic and gas exchange relations (Vieira Santos et al, 2001;Malik et al, 2021).…”
