Maize Variety to Plant: Each and every year, farmers get poor harvests because they planted the wrong varieties in their regions. Before you try and new maize variety, if you had never grown it before, isolate a small portion of land and observe how it grows into full production.ย  When sure that the maize variety can do well in your region. This avoids the risk of planting new varieties without the full knowledge of their performance.

Maize Variety

Every year, many maize farmers plant the wrong maize seed varieties, ending up with poor yields for lack of correct information. Persistentย advertising and promotionย of certain maize seed varieties by seed companies are partly to blame for the problem. Another problem is that farmers usually ask local agrovet shops to sell them the best maize varieties. This approach is not effective because seed stockists will always recommend any variety especially that of stock that is not moving.

Farmers should, therefore, be very careful when choosing maize seed varieties to plant. The seeds are developed on the basis of altitude, rainfall, type of soil and temperature and other climatic conditions. To meet the needs of farmers in every climatic region, researchers have developed seed varieties that do well in those regions. It is therefore important for farmers to buy seeds that can do well in theirย geographicalย regions. It is also important that farmers seek advice from extension officers,ย agriculturalย or research institutions before buying any maize seed.

Before adopting any new seed variety, it is important that farmers isolate a small portion of land, plant the variety and observe its characteristics. Check if the variety is prone to lodging (falling due to wind) if the ears open early before maturity, which allows water and rotting, the yield and any other negative characteristic. When you have established that the variety is good,ย proceedย to large-scale production. We give this advice to caution farmers against buying new seed varieties (which may not have the desired qualities) as may be claimed by seed companies or seed stockists.

Good management of maize through the production phases is important. Low soil fertility, soil acidity, late land preparation and planting, poor weeding and even using the wrong planting methods can contribute to low maize yields. Farmers are advised to grow maize varieties that do well in their agro-ecological regions as shown in theย map.

Below, we provide farmers with some of the new and alternative maize seed varieties:

Another suitable variety is WH 303 (IR) from Western Seed co.

ย Important maize planting tips:ย In order to get a good maize crop, farmers need to go by the following planting tips:

ย Land preparation:ย The land to be used for planting should be prepared early enough.

Planting: Planting should be done early preferably two weeks before the rains stop. Maize planted after the rains have started cannot germinate well because the soil temperatures tend to go down as the rains persist.

Most farmers practice dry planting (planting when the rains have not started); in this case, the germination tends to be vigorous. Research has shown that if a farmer plants two weeks after the onset of the rains, they lose an average of 2ยฝ bags of maize per acre per week. Maize that is planted early also benefits from nitrogen flush โ€“ this is a process where the newly planted maize benefits from nitrogen fixed into the soil from the atmosphere at the onset of the rains before it is lost through leaching.

ย Spacing:ย It is important to space your maize correctly. There are two spacing options:

  1. i) 75x30cm when planting one seed per hole.
  2. ii) 75x60cm when planting 2 seeds per hole.

Always plant certified seeds to get a good maize harvest.
