KALRO-KCEP - CRAL Common Dry Beans Extension Manual

Abstract

Pulses, or grain legumes in general, are an essential source of supplementary protein to daily diets based on cereals and starchy for a predominantly vegetarian population and those who cannot afford expensive animal protein. Pulses are therefore often regarded as poor man’s meat”. They also provide energy, protein, essential minerals, vitamins and several compounds considered beneficial for good health. Their cultivation enriches soil by adding nitrogen, and improves the physical, chemical and biological soil properties. They are also well suited to diverse environments and fit in various cropping systems owing to their wide adaptability, low input requirements, fast growth, nitrogen fixing and weed smothering ability. Their short growing period and photoperiod sensitivity make them suitable for crop intensification and diversification. Notwithstanding their high production potential, their productivity is generally low as these are cultivated on poor lands, with no or little inputs, and are susceptible to several abiotic and biotic stresses.
