Planting Guide for Corn

1. Planning and Budgeting

PLANNING. Identify the resources and materials that you will need for planting. It is important that you secure the necessary documents, especially if you will borrow money from the bank.

SOIL TESTING. Have your farm soil tested by the Bureau of Soils Regional Office to know its fertilization and acidity level. In this way, you will be informed about the right amount of fertilizer to be used and if your soil still needs lime.

2. Land Preparation

PLOWING AND TILLING. Prepare the land properly for the ideal growth of the Pioneer hybrid seed that you will plant. Good plowing and tilling of the land will help avoid early growth of weeds in your corn farm.

For light soil, it is recommended that you plow the land once and till it also once.

For clay or heavy soil, it is recommended that you plow the land once and you till it twice with 7-10 days interval for the tilling.

FURROWING. On the day of sowing, build furrows with a 70 centimeter distance from each other and a depth of 8 centimeters for wet season or 10 centimeters for dry season.

3. PLANTING

For minimum tillage: Spray 2-3 liters of glyphosate herbicide 5-7 days before planting.

Check your soil if it has the correct amount of moisture before planting. This will ensure the high rate and even growth of the seeds.

The spacing between the seeds is specified according to the type of hybrid seed that you will plant. It ranges from 20-25cm for the hill spacing and 60-70cm for the row spacing. Plant 1 seed per hill and cover it with soil that has a depth of 2-5cm.

4. Fertilizer Application (before planting and 30 days after planting)

BASAL FERTILIZER. Before planting, apply the fertilizer evenly at each furrow and cover it with soil that has a depth of 2-3cm to prevent the seeds from touching the fertilizer. The quantity of fertilizer to be used depends on the result of the soil test conducted on your land or the recommended rate of fertilizer use.

SIDEDRESSING. Add nitrogen-based fertilizer (Urea) on the sides of each plant, scatter the fertilizer linearly with a 4-6cm distance from the base of the corn plant. Cover the fertilizer by hilling the soil up with a depth of 8-10cm.

5. Irrigation

Irrigate the land on the designated dates of irrigation if needed especially during the dry season. The recommended schedule of irrigation is: 0-3 days, 13-15 days, 30-35 days, 45-55 days and 65-80 days after planting.

6. Weed Control

For Conventional Products and Products WITHOUT Roundup Ready Corn 2 Trait:

Do shallow cultivation, off-barring, and spot weeding 12-20 days after planting. These weed control practices may be repeated 35 days after planting.

HERBICIDE (OPTIONAL). Use pre-emergence herbicide, such as Pendimethaline or Atrazine, 1-2 days after planting. Follow the right amount of herbicide to be used for a 16-liter sprayer, as indicated in its label.

For Products WITH Roundup Ready Corn 2 Trait:

FIRST SPRAYING. Spray the recommended glyphosate herbicide (approved by the Fertilizer & Pesticide Authority or FPA) at 12-15 days after planting or when the weeds are already 1-2 inches high. Follow the right amount of herbicide to be used for a 16-liter sprayer, as indicated in its label. Shallow cultivation and off-baring is not needed anymore for the first spraying.

SECOND SPRAYING (OPTIONAL). Spray herbicide at 35-40 days after planting or when the weed is already 1-2 inches high.

7. Insect Pest Management

NOTE: Read the label of the product properly and ensure that you are wearing protective clothes before spraying.

For Conventional Products and Products WITHOUT YieldGard Corn Borer Protection Trait:

OPTION #1: Use granular insecticide such as Carbofuran or Fipronil during basal application to fight off pests such as ants, white grub, corn thrip, cutworm and seedling maggot.

OPTION #2: If you notice infestation of cutworm, earworm or brown planthopper, mix 2-3 scoops of LannateTM 40SP to a 16-liter sprayer and apply it within 7-30 days after planting.

OPTION #3: In controlling locusts and planthoppers, apply xylene-based insectide such as Cypermethrin within 48-65 days after planting.

If golden natural sprayable oil (GNSO) is available, mix 40ml of it in each 16 liters of the water for the sprayable insecticide to increase the potency of the pesticide, especially against brown planthopper.

For Products WITH YieldGard Corn Borer Protection Trait:

OPTION #1: Plant PioneerĀ® hybrid with YIELDGARD CORN BORER PROTECTION TRAIT for season-long protection against corn borer, true armyworm, and pink stemborer (Sesamia).

OPTION #2: Use granular insecticide such as Carbofuran or Fipronil during basal application to fight off pests such as ants, white grub, corn thrip, cutworm and seedling maggot.

OPTION #3: If you notice infestation of cutworm, earworm or brown planthopper, mix 2-3 scoops of LannateTM 40SP to a 16-liter sprayer and apply it within 7-30 days after planting.

OPTION #4: In controlling locusts and planthoppers, apply xylene-based insectide such as Cypermethrin within 48-65 days after planting.

If golden natural sprayable oil (GNSO) is available, mix 40ml of it in each 16 liters of the water for the sprayable insecticide to increase the potency of the pesticide, especially against brown planthopper.

8. Plant Disease Control

Visit you corn field regularly. Immediately remove corn plants that manifest symptoms of diseases, such as leaf blight and stalk rot. Burn the diseased plants.

9. Harvesting

The corn plant is ready to harvest once the kernels are already dark in color and shiny, and once the plant leaves and stems are dry. Harvest and dehusk the corn in your farm.

10. Drying, Shelling and Storing

DRYING. Dry the corn ear to 18-21% moisture content (MC).

  • Sun drying for 2-3 days
  • Mechanical drying for 6-8 hours

 

SHELLING. Dry the shelled corn grains to 14% MC.

STORING. Store the harvested corn grains in a cool and dry place that is free from insects and rodents.
