Thin the crop at knee height (6 weeks after planting). Pull out the weaker, unhealthy or excess maize plants. It gives space for healthy maize to grow. You can use the pulled plants to feed your animals.
Weeds compete with maize for water, nutrients and space. Weed your maize after 6 – 8 weeks using a hoe. Weed again every 4 weeks.
Topdress with CAN when the crop is knee high. This will add nitrogen to your soil and stop your crop from turning yellow. Add 1 bottletop of CAN in a 15 cm ring around each plant. Topdress again when the maize starts to tassle.
