Moringa Leaf Extract

Recently, the use of biostimulants as natural and eco-friendly fertilizers has received increasing attention because of their efficiency in terms of improving crops’ qualitative and quantitative parameters, i.e., growth, yield, and chemical composition. We studied the effect of four biostimulants—humic acid (20 g/L), vermicompost tea (15 mL/L), moringa leaf extract (1:30 v/v), and yeast extract (5 g/L), with tap water as a control treatment—on the qualitative and quantitative characteristics of snap beans. The experiment was designed using a complete randomized block with triplicates. The results showed a significant improvement in treated plant performance (growth and yield), chlorophyll, and chemical composition compared to untreated plants. Using moringa leaf extract increased the plant height, number of leaves and branches/plant, and fresh and dry weight. Additionally, the diameter of the treated plant stems and the quality of the crop and pods were also significantly higher than those of plants treated with vermicompost or humic acid extract. It is also noted that the profile of amino acids was improved using all tested biostimulants. This leads to the conclusion that the addition of moringa leaf extract and vermicompost tea not only positively affects the qualitative and quantitative properties of snap bean but is also reflected in its nutritional value as a plant-based food.

Because of interest in maximizing production per unit area in regions where the land base is limited, the effects of planting density; (16–116 plants m−2) and planting design on pod yield of bush snap bean (Phaseolus vulgaris L.) were measured in replicated field trials with cv. Harvester in 1980 and 1981. Three planting designs were used: (a) conventional row designs with interplant spacing of 5 cm and interrow spacing of 20, 45, 80 and 125 cm; (b) square designs with interplant and interrow spacings both at 10, 15, 20 and 25 cm; and (c) triangle designs (honeycomb) with plants arranged at equal distances of 10, 15, 20 and 25 cm from each of their six nearest neighbors. In all three planting designs, higher planting densities (up to 116 plants m−2) gave higher pod yields per unit area. Except for the lower response in the square design in 1981, increases in yield with increasing density were similar for all designs in both years. Pod yields did not differ from one design to the other in 1980. In 1981, the triangle design gave the highest average yield and the row design gave the lowest average yield. The results confirm observations of yield advantages in planting designs which use equal spacing in all directions.Key words: Yield-density relationship, row spacing, honeycomb design, snap bean, Phaseolus vulgaris
