Stage 1: Sowing seeds
Voting technique:
Soil should have 85-90% moisture. Before placing the pot, cover with rotten manure or microorganic fertilizer and superphosphate, if the field is acidic, add lime powder. Place the corn plants in the direction of the leaves spreading out to the sides of the row and perpendicular to the length of the bed, and plant them in the field when the corn plants reach 2-3 true leaves.
Straight sowing:
Put the seeds in holes 7-12 cm apart, 1-2 seeds in each hole. Or you can plow a trench to create a trench and sow seeds in a groove.
Stage 2: Care and irrigation
Prune:
Prune branches for fast growth and large fruit. Only 1-2 plants per hole. Remove weak, dead plants.
Sprinklers:
The first stage needs to be watered a lot, then once every 5-7 days. When the plant has grown stably, water once every 2-3 weeks.
Fertilization:
With soil lacking nutrients should add fertilizer to the soil. Divide the amount of fertilizer into 3 times to apply, 2/3 of the amount of phosphate fertilizer is used for priming.
The first time, 15 days after sowing, 1/3 of the amount of urea, 1/3 of phosphorus.
30 days after sowing, fertilize 1/3 of the amount of urea, 1/2 of the amount of potassium fertilizer.
Apply the last fertilizer at 45 days after sowing all remaining fertilizers.
Pests:
Purple sticky corn has extremely good disease resistance, the rate of pests and diseases is much lower than other types of corn. However, to ensure good growth of corn, we still need to weed and spray a little medicine.

Stage 3: Harvest
Depending on the purpose that you harvest young or old, after harvesting the fruit, you can use the corn stalks to make fertilizer or forage.
Determine when to harvest corn by observing the corn kernels on the top and underside of the pods. As the leaves begin to wither, the seeds harden.
You will know the plant is fully ripe when you see the leaves turn yellow from the bottom up.
