When is the latest time to plant broad beans (when is the best time to plant broad beans this year)

Broad beans are the third most important winter edible bean crop in the world and belong to the category of small grains. They have high economic value in life. Therefore, broad beans are also a crop that people need to produce in large quantities. So when is the best time to plant broad beans? And how to plant them?

When is the latest time to plant broad beans?

Broad beans are generally planted in spring or autumn . In spring, they are usually sown from mid-to-late March to early April, while in autumn, they are sown between October and November.

Because broad beans are afraid of heat, it is generally advisable to sow them in early October or early November to avoid low temperature and frost damage during the flowering period. The best time for autumn sowing of broad beans in Shanghai is from mid-to-late October to early November .

However, the sowing time of broad beans varies from place to place, and the minimum temperature for broad beans to germinate is 5-6 degrees, and the suitable temperature is about 15 degrees. Therefore, it is best to plant when the ground temperature of 5-10 cm is stable at 10 degrees.

How to grow high-quality broad beans

①Select varieties

First of all, broad beans need to choose high-quality varieties with high yield, good quality and strong disease resistance to ensure stable growth during the initial planting.

②Selection of planting plots

Secondly, you need to choose land suitable for growing broad beans. Broad beans like moisture but are not tolerant to waterlogging, so you should choose land with fertile soil and plenty of sunlight for planting.

However, the trenches must be deep and the ridges must be high, and the surface of the ridges must be raked flat so that the trenches are connected and watertight.

③Choose the right fertilizer

Broad beans require fertilizer to grow, so when planting them, we also need to choose fertilizers suitable for broad beans, generally farmyard manure and phosphorus and potassium fertilizers.

④Choose the sowing time

Because early sowing will cause early flowering and affect yield, while delayed sowing will affect the crops planted in the spring of next year. Therefore, 5 days before and after the frost, soil and fertilizer should be covered after sowing , and rhizobium can be mixed with seeds if conditions permit.

⑤Field management

Finally, we need to strengthen field management, top pruning, and prevent and control major diseases of broad beans such as red spot and rust. When you want to store broad beans, you can harvest them when the leaves fall and the middle and lower pods are fully mature, and then dry, thresh and store them.
