It is best to irrigate the plants in the morning, so the excess moisture evaporates or drains away before the temperatures drop in the evening. This minimizes the risk of fungal diseases and pest infestations.
Fertilization for Melilotus Indicus (L.) All.
Melilotus Indicus (L.) All. is a leguminous plant that fixes nitrogen from the atmosphere through its root nodules and makes it available to other plants. However, the soil may still require additional fertilizers for the optimal growth of the Melilotus Indicus (L.) All. plant.
Use a balanced fertilizer containing equal amounts of nitrogen, phosphorus, and potassium (NPK) during the planting process. You can also apply phosphorus-based fertilizers once the plants have established themselves in the soil. Alternatively, you can use organic fertilizers such as compost or well-rotted manure, which provides more sustainable nourishment to the soil.
If you want to increase the nitrogen content in the soil, you can plant Melilotus Indicus (L.) All. as part of the crop rotation process, allowing it to fix more nitrogen into the soil.
Pruning for Melilotus Indicus (L.) All.
Melilotus Indicus (L.) All. is a legume that can benefit from occasional pruning. This involves cutting back the plants to remove dead or diseased parts and promote new growth.
Prune the plants when the flowers have withered, cutting off the top two-thirds of the plant. This is because the lower stem often contains more fibrous material which is less palatable to livestock.
Mechanical mowing is also a common method of pruning Melilotus Indicus (L.) All. It promotes vigorous regrowth and improves the overall quality of the plant. Cultivated Melilotus Indicus (L.) All. is usually mowed up to three times per year in the first year and twice in the subsequent years of cultivation.
