How to Grow Hyacinth Beans for High Yield? A Detailed Guide to Practical Growing Techniques
The hyacinth bean, also known as the black-eyed pea or lablab bean, is an annual or overwintering herbaceous climbing plant, and its tender pods and mature beans are both used for food. It has the effect of strengthening the spleen and stopping diarrhea, and also has a notable effect in reducing tumors. It is cultivated all over the world. Below, Qinnong Net brings you the high-yield hyacinth bean growing techniques.
1. Reasonable crop rotation
Hyacinth bean cultivation should avoid repeated cropping and continuous cropping. Repeated and continuous cropping of hyacinth beans not only increases the probability of pest and disease outbreaks, leading to reduced yield or even total crop failure, but also results in higher pesticide residues, harming the lives and health of consumers. Continuous cropping leads to a large base of surviving pests and diseases in the field, a high amount of pesticide use, and high levels of harmful substances in the hyacinth beans, creating a vicious cycle. Therefore, crop rotation is very important. Generally, rotate with non-legume crops for 2 to 3 years, while for perennial crops, a new plot must be selected for planting 3 years after harvest.
2. Fertilizer and water management
The pod-setting period of hyacinth beans is relatively long. To ensure its yield, sufficient nutrients must be provided to guarantee normal pod setting, so fertilization is the key point for achieving high and quality yields of hyacinth beans. When fertilizing, in order to achieve pollution-free cultivation, apply organic fertilizer or farmyard manure as much as possible, and use chemical fertilizer as little as possible or not at all. Fertilization should be mainly basal fertilizer, supplemented by topdressing. Fertilize at the seedling stage according to the growth state of the seedlings, and apply heavy fertilizer at flowering and pod setting to ensure the nutrients needed for flowering and pod setting. Although hyacinth beans have extremely strong drought tolerance, they still need moderate watering during the growing period. Watering depends on the regional climate and rainfall. Generally, arid regions with little rain need frequent watering, while humid regions with plenty of rain generally need little or no watering. On the contrary, attention should also be paid to drainage measures during long rainy periods.
3. Plant adjustment
When the hyacinth bean plants begin to grow, stakes should be inserted and trellises built in time, and the vines should be guided onto the stakes. This helps the branches and vines of the hyacinth bean attach and form a fence-like growth pattern. In addition, during the peak growing season, the leaves of hyacinth beans should be pruned regularly to prevent excessive vegetative growth, reduce nutrient consumption, and increase ventilation and light penetration, which is beneficial to the growth of hyacinth beans.
4. Pest and disease control
Pest and disease control for hyacinth beans is also extremely important. Many vegetable growers do not pay attention to pests and diseases, resulting in serious losses. The main diseases of hyacinth beans are rust and brown spot, which mainly harm the leaves and pods, causing reduced yield. When the disease occurs, use thiophanate-methyl or difenoconazole diluted with water and spray for control. The main pests are owlet moths, small gray butterflies and tobacco budworms, which suck on the tender parts of the hyacinth bean plants, causing the hyacinth beans to stop growing or grow poorly, and easily causing deformed pods. When they occur, use specialized insecticides diluted and spray to kill them.
The above are the high-yield hyacinth bean growing techniques brought to you by Qinnong Net. To achieve high and quality yields of hyacinth beans, the above points cannot be ignored. We hope this helps you. For more agricultural knowledge, please stay tuned to Qinnong Net.
