Please introduce to our technical farmers the cultivation of hybrid corn BIOSEED 9696.

Characteristic :

- Short day (110 days in Lam Dong)
- High productivity.
- Orange seeds, Corn.
- Good resistance to pests and diseases.
- Body is big, hard, roots are strong, deeply ingested.
- Each corn has 14-18 rows.

Part time:

Corn plants can be grown year-round, during the dry season and the rainy season. However, the following issues should be noted:
- There must be enough irrigation water in the dry season
- Do not be flooded in the rainy season.

Land preparation:

- There is no need to make soil on floating rice land.
- On upland fields or fields need plowing or plowing 15-25cm deep.
- In the summer-autumn and autumn-winter season, ditches should be dug to drain water.

Sowing density and seed quantity for 1 ha:

The amount of seed needed for 1 hectare: 15kg.

- Planting at a distance of 75x25cm. Each seed is planted 1 seed.

To prevent insect bites from breaking corn plants at a young age, it is possible to treat soil with granular drugs such as Basudin 10H, Furadan 3H, . at a dose of 1 - 1.5 kg / man (or mix the medicine with ash to fill seeds at sowing).

Fertilization : Amount of fertilizer for 1 ha:

- Urea: 300 kg
- DAP: 100 - 150 kg (or 300 kg super phosphate)
- Kcl: 50-100 kg.

How to apply:

- Applying all fertilizer DAP (or Supe spread) + ½ fertilizer KCl at sowing (mix well into soil, 5 - 7cm away from corn).
- First-time application: phân urea fertilizer at 15 - 20 days after sowing (when the corn is knee-high).
- Second application: ½ urea fertilizer residue + ½ KCL at the time of corn hatching (40 days after sowing).

Sprinklers :

Water depending on the requirements of corn plants. Do not allow corn to dry or flood. When the corn is large, it is possible to apply watering or overflowing.Note : The period of 20 days before the stubble and 20 days after the stubble, do not let the corn field become dehydrated.

Weeding:

Keep the corn field clean with grass to limit weed competition. First weeding 15–20 days after sowing and second time 35-40 days after sowing.

Pest and disease prevention:

- Prevention of aphids by spraying common drugs like Methyl Parathion 50 ND, Azodrin 50DD, Padan 95 SP .
- Prevention of stem borer and fruit chisel by removing granular drugs such as Furadan 3H, Basudin 10H on corn tops. Discard 2 times at 20-25 days after sowing and 40-50 days after sowing. Each time remove 3-5 seeds on the tree.
- For sheath blight disease should only be sprayed when the disease tends to spread. Use 1 of 2 drugs Validacin 3DD or Anvil 5S.
- For leaf rust: use Zineb 75 BHN spray when detecting disease.
