1.0 INTRODUCTION

Soybean is one of the most important food and cash crops in Malawi. It is a good source of protein, vitamins and vegetable oils. However, in recent years production has not been satisfactory, as a result, Malawi has been importing substantial amounts of vegetable oils. It is therefore important to increase production of soybean as this would play an important role in import substitution. Like other legumes, soybean is capable of fixing atmospheric nitrogen. When grown in rotation with other crops such as maize or tobacco, it improves soil fertility.

The core objective is to improve knowledge and skills among small scale farmers involved in soybean production to produce an increase soybean yield in a sustainable way

By the end of this lesson, the farmer should be able to understand:

  • Good management practices for soybean production
  • How to better manage soybean pests and diseases
  • Knowledge on improving soybean productivity
  • Knowledge on post-harvest handling of soybeans

2.0 ENVIRONMENTAL REQUIREMENTS & VARIETY SELECTION

2.1. Environmental Requirements

  • Soybeans are well adapted for production in all agro-ecological zones in Malawi
  • Grows best in deep, rich and aerated soils
  • To avoid drought stress, do not plant soybeans in sandy, gravelly, or shallow soils
  • Growing soybean in waterlogged soils or soils with surfaces that can crust will lead to poor seedling emergence
  • Farmers must select varieties that are adaptable and recommended in their respective agro-ecological areas.

2.2. Recommended soybean varieties grown in Malawi
