Important farm practices tips


This is getting rid of unwanted plants that grows alongside planted crops and compete with them for nutrients and water. They also harbour pest and diseases which might be harmful to plants and also reducing the yields.


Nutrients helps plants in good growth and high yields. There are various fertilizers types that can be added to plants, they include the basal,foliar through the macro and micro nutrient elements

Basal fertilizers

These are available in Argostores countrywide they include DAP,CAN,NPK and UREA.


These are nutrition added to soil to increase nutrients they include animal droppings and decomposed Waste from grass and plant waste.

Sheep, goats and cows waste can be dried to make manure then added to soil to add nutrition. Decomposed waste can also be added to the soil to provide maximum nutrition to plants.

Manure is widely used and available in Kenya with cheap price.

It has proved to be an effective method in crop production especially in semi-arid areas like Perkerra irrigation scheme in Marigat area Kenya. High-yielding crops are produced in this area with irrigation practice.

Types of irrigation method include.

  • Drip irrigation
  • Canal irrigation
  • Overhead irrigation


This is a practice of adding materials like grass Waste or husks on nursery beds or on top of root seedlings covered by soil after planting.

Mulching helps to conserve moisture in the soil as it reduces evaporation of water from the soil. It also helps to suppress weeds. Unwanted plants (weeds) are discouraged to grow when mulching is done, because the soil gets exposed to minimal sunlight.

This practice is effective on nursery beds and newly transplanted crops.


Some plants develop Overgrown branches, buds and also yellow or withered leaves. It is important to pluck off these leaves and branches to make a clean plantation. Also to reduce infection to other leaves which may occur with infected or withered leaves.
