Golden Sweet Corn

Growing Golden Sweet Corn

Cultivation Environment :

Golden sweet corn, which likes warm and wet weather, can be grown all year round here. The best soil is thick, richly organic sandy loam with good drainage and a pH between 6.0 and 7.0. Different species should be planted at different times or separated by a spacing of over 300 to 500 metres to avoid the impact of hybridization on quality.

Planting and Spacing :

Transplanting and direct sowing are possible, and germination takes about 4 days. The seedlings can be transplanted when coming into 2 pairs of true leaves (about 8 to 10 days after sowing). For direct sowing, put 2 seeds into each hole. After germination, pick the weak seedling and keep the healthy one.

Row and plant spacing should be about 40 to 50 cm and 25 to 30 cm respectively.

Application of Fertilizer and Management :

Basal dressing :

Apply 1,000 kg compost, 50 kg peanut cake, 50 kg bone meal and 16 kg Chitogreen to each d.c.

Use compost, peanut cake, and bone meal to prepare the planting bed first. Mix Chitogreen with the soil in the bed evenly 2 days before planting the seedlings.

Top dressing :

Apply fertilizer for the first time 1 week after the planting. Apply 25 kg peanut cake and bone meal each as well as 40 kg organic fertilizer (N:P:K= 2:8:2) to each d.c.

Apply fertilizer again before the appearing of tassel (about 4 weeks after the planting), with 25 kg peanut cake and bone meal each as well as 120 kg organic fertilizer (N:P:K= 2:8:2) to be applied to each d.c..

Apply fertilizer for the third time after removing the second ear (about 7 weeks after the planting), with the same quantity as the first one.

During the growth period, appropriate water should be maintained in the soil, and intertilled weeding and earthing-up be performed for 2 to 3 times. At the initial growth stage, side buds should be removed to facilitate strong growth. If the second ear grows strongly, it can be kept and harvested when ripe.

(1 d.c.= 674 square metres or 7,260 square feet)

Harvesting :

Ears can be harvested when the silk on their top has turned dark brown, and begun to dry and roll up, and the kernels are plump (about 70 to 80 days after sowing). They are best harvested in the morning and transported for marketing immediately.
