Peanut Sprout Cultivation Methods and Key Technical Points

We generally can find peanut sprouts at large vegetable markets or supermarkets; they are a relatively fresh food with high nutritional value. So, are you all familiar with how to cultivate peanut sprouts? Let's take a look together today!

1. Cultivation of Peanut Sprouts

For cultivating peanut sprouts, choose peanuts produced in the current year, and when shelling the seeds, remove diseased kernels, shriveled kernels, and broken kernels. Soak the seeds in warm water at 20°C for 12 to 20 hours. Then carry out two rounds of sprouting at a suitable temperature, stacking the seedling trays, with every 5 trays as one stack; place an empty tray on top, and cover the empty tray with a wet gunny sack or black film to retain moisture, and simply keep it shaded from light as usual.

2. Sprouting Management of Peanut Sprouts

1. Peanut kernels cannot germinate at 10°C; the optimal germination temperature is 25 to 30°C, and after 3 to 4 days the germination rate can reach 95%. For sprouting, use flat-bottomed shallow plastic mesh containers or plastic seedling trays, with the seed thickness not exceeding 4 cm, and water 2 to 3 times a day; each watering should soak through, so as to prevent the seeds from overheating and rotting.

2. After 2 to 3 days of the first sprouting, sort the sprouted seeds once, remove the seeds that have not germinated, and carry out a second sprouting for the seeds that have germinated, with the suitable temperature at 20 to 25°C. If the temperature is too high, although growth is fast, the sprouts are thin and weak and tend to age; if the temperature is too low, growth is slow, and over a long time the sprouts easily rot or the cotyledons open and separate, resulting in poor quality.

3. Stack the seedling trays, with every 5 trays as one stack, place an empty tray on top, and cover the empty tray with a wet gunny sack or black film to retain moisture. Water 3 to 4 times a day, making sure to soak the seeds in the seedling trays thoroughly, so as to carry away respiratory heat and ensure the moisture and oxygen needed for peanut germination, while also carrying out “tray turning”. Water must not accumulate in the trays, so as to prevent the seeds from rotting. After 6 to 7 days, they can be harvested.

During the growth period of peanut sprouts, always keep them in darkness. After sowing, stack the seedling trays, cover them with black film to block light, and press a layer of wooden boards on the sprouts to give them a certain pressure, which can make the sprouts grow plump and sturdy.
