1781 - EDAMAME SOY BEAN
The soy plant (Glycine max) is an annual herbaceous plant that originates from eastern Asia; produces numerous pods containing about 3 medium-sized grains. This plant also grows in Italy, especially in environments where it can benefit from irrigation and where summer temperatures do not exceed 30 °C, even if it tolerates 40 °C. It grows well in the Po Valley, in areas where corn is traditionally grown, although this vegetable adapts and is also productive in the Center and South.
The soybean sowing period begins in early May and ends in mid-June with the planting of the earliest varieties. The plants are very resistant and if watered properly, they will have no problem growing healthy and producing abundant pods.
In any case, during the vegetative development, take care to eliminate the weeds that grow around the plants by hoeing or by uprooting the weeds by hand.
The soybean harvest takes place towards the end of September, when the plants have lost their leaves and have a brownish colour: in these conditions, by shaking the pods you can feel the seeds move inside them.
If, on the other hand, you cultivate soybeans to harvest the edamame, the immature pods of the plant, you will have to anticipate the operations by a few months, in fact in this case the soybean harvest begins between mid-July and August.
The soybean sowing period begins in early May and ends in mid-June with the planting of the earliest varieties. Prepare the soil by working it properly, then sow the soybeans in a row, placing one seed about every 6 cm, at a depth of about 3 cm. If you intend to grow several soybean rows, make them about 50 cm apart from each other. Be aware that when soybeans are sown, Rhizobium japonicum must be inoculated into the seed, a bacterium with which the plant lives in symbiosis and which allows it, among other things, to recover nutrients from the soil more efficiently.
