Introduction

Kenyan farmers are increasingly seeking profitability and soil health solutions amid climate stress. The implementation of a 3-step intercropping system offers a promising solution. This guide trains farmers to select drought-tolerant legume species, such as cowpeas, which pair with maize for nitrogen fixation. It explains the benefits of using precise spacing (1.5m between rows) to optimize light and root competition. Lastly, timing legume pruning enhances maize ear development, as recent field trials by the Kenya Agricultural & Livestock Research Organization (KALRO) indicate a remarkable 34% yield increase compared to monocrop maize, with 28% less fertilizer needed.

Background & Context

Sustainable agriculture is at the heart of Kenya's development strategy. With over 16,000 certified organic farmers, Kenya leads Africa in organic production. According to the FAO, strategies like organic farming, agroforestry, and efficient water management significantly contribute to enhancing soil fertility and crop yields. The International Water Management Institute reports that adopting modern irrigation techniques has further boosted these yields by reducing water use.

Key Insights or Strategies
