Climatic and Soil Requirements for Maize Farming in Kenya
Maize is a warm-season crop that requires specific climate and soil conditions to grow successfully. The ideal climate for maize farming in Kenya is found in areas with an altitude ranging from 900 to 2,500 meters above sea level.
The minimum temperature required for germination and growth is 10-15°C. Maize thrives in areas with a temperature range of 20-30°C. Maize requires well-drained soils with a pH level of 5.8-7.0.
Loamy and sandy loam soils are suitable for maize farming in Kenya. It is important to note that maize is sensitive to soil compaction, and it is therefore necessary to ensure proper soil preparation before planting.
The soil fertility and capacity of many areas in Kenya are gradually decreasing due to rapid population growth that puts pressure on land resources. Depletion of soil in macronutrients such as N, P, and K, as well as important micronutrients like copper and zinc, can also be a challenge for maize farmers.
To ensure optimal maize growth and yield, it is recommended to conduct soil tests to determine the nutrient levels in the soil. Based on the test results, farmers can apply the appropriate fertilizers to improve soil fertility and ensure proper maize growth.
Maize Varieties in Kenya
Maize is a staple food crop in Kenya, and there are several varieties of maize seeds available for farmers to choose from. These varieties are grouped into two main categories: Hybrid Maize and Open Pollinated Maize (OPV).
Hybrid Maize
Hybrid maize is a cross between two or more inbred lines, resulting in a plant with superior characteristics such as high yields, disease resistance, and drought tolerance.
Hybrid maize varieties in Kenya include the DHO series (DHO 1, DHO 2, DHO 4), the Five series (H513, H515, H516), H614D, Duma 43, DK 8031, the Pannar series, among others.
These varieties have been developed to suit different agroecological zones and farmer preferences.
Hybrid maize varieties are generally more productive than OPV, with higher yields and better resistance to pests and diseases. They also have better drought tolerance, making them suitable for areas with limited rainfall.
However, hybrid maize seeds are more expensive than OPV seeds, and farmers need to purchase new seeds every planting season.
Open Pollinated Maize
Open Pollinated Maize (OPV) varieties are those that are reproduced by natural pollination, without any human intervention. OPV varieties in Kenya include Longe 5, H614, H621, H628, H629, H630, H631, H632, and H633.
These varieties are well adapted to different agroecological zones and are preferred by small-scale farmers due to their low cost and ability to produce seeds for the next planting season.
OPV varieties are generally less productive than hybrid maize, with lower yields and poorer resistance to pests and diseases. However, they are less expensive than hybrid maize seeds and can be saved for planting in the next season.
They are also preferred by farmers who practice organic farming as they do not require the use of chemical fertilizers and pesticides.
Land Preparation for Maize Farming in Kenya
Before planting maize, it is essential to prepare the land correctly. The first step is to clear the land of any weeds, debris, or other plant residues. This can be done manually or using herbicides.
However, manual clearing is recommended as it is cheaper and more environmentally friendly.
After clearing the land, the next step is to plow the land. Plowing helps to break up soil clods and create a fine seedbed. The depth of plowing should be between 15-20 cm to ensure good root development.
Farmers should avoid over-plowing as it can lead to soil erosion and loss of soil nutrients.
Once the land is plowed, it is recommended to harrow it. Harrowing helps to further break up soil clods and create a smooth seedbed. It also helps to mix soil nutrients evenly, making them readily available for plant uptake. Harrowing should be done when the soil is moist to avoid damaging the soil structure.
Farmers should also consider applying manure or fertilizer before planting maize. This helps to provide the necessary nutrients for plant growth. The type and amount of fertilizer or manure applied depend on the soil fertility level and the maize variety grown.
It is recommended to conduct a soil test to determine the soil nutrient status before applying any fertilizer or manure.
