Effect of Spraying Frequency of Moringa Leaf Extract on Growth and Yield of Amaranth (Amaranthus cruentus L.).

Abstract

Global interest in sustainable agriculture and natural plant extracts to enhance crop yield is growing. This study investigates whether Moringa leaf extract, known for its nutritional value, can improve the growth and yield of Amaranth (Amaranthus cruentus). A pot experiment was conducted at Ekiti State University's Teaching and Research Farm in Nigeria. Amaranth seeds were planted thrice in 5-kilogram soil-filled pots, each receiving one, two, or three sprays of 25 ml fresh Moringa leaf extract. Data on plant height, leaf count, leaf area, and yield biomass were collected. Results indicated significant differences (p ≤ 0.5) between spraying frequencies and the control group. Notably, plants sprayed three times exhibited the tallest height (32.06 cm), highest leaf count (32.78), and most excellent leaf area (996.3 cm2) five weeks after planting. Furthermore, the threespray regimen yielded the highest biomass, outperforming the control. Overall, spraying Amaranth with Moringa leaf extract improved yield, with increased spraying frequency correlating with enhanced performance. This suggests that local farmers could benefit from applying Moringa leaf extract to boost production due to its affordability and accessibility.
