Effect of biofertilizer application on agromorphological parameters of field-grown Mung bean (Vigna radiata (L.) Wilczeck)

Abstract

The mung bean (Vigna radiata), commonly known as “mung bean”, is a seed legume rich in protein and carbohydrates, but little known in Burkina Faso. However, its production is very low due to the fact that it is little known by the Burkinabe population. With a view to popularizing, promoting and enhancing its cultivation, a trial to study the effect of biofertilizers on the morphophysiological and agronomic parameters of mung bean was set up in Tenkodogo in the Centre-Est region. A single type of biofertilizer (wood ash) at different doses (0, 50 and 100 kg/ha) was used in a randomized complete block design with four replications and three treatments. These parameters were measured. Overall, the results indicate that the 50kg/ha and 100kg/ha doses significantly improve physiological, agronomic and grain yield parameters compared with the control treatment. The 50kg/ha dose proved to be the optimum dose for obtaining higher yields. Wood ash can therefore be used as a natural fertilizer to improve soil fertility and increase crop yields, if used at the right dose.

Key words: Mung bean, biofertilizer, ash, parameters, field.
