Soil fertility decline pose a great threat to crop production in Malawi. Biochar application enhances crop yield and productivity; however, feedstock type and rates may influence its performance. The chapter illustrates how biochar application at different rates and feedstock types contribute to significant effects on plant height, stem diameter, leaf canopy and leaf area of soyabean causing a 13.8%, 20.6%, 50.6% and 19.1% increase, respectively. Biochar made from maize cores can cause an improvement in above ground biomass, below ground biomass, 100 seeds weight, and number of seeds per pod as compared to groundnut shell biochar. However, from this study reported in this chapter biochar did not affect grain weight and number of pods per plant. Data in the current chapter also reveals significant effects of biochar on Fe and Ca concentration in soybean grain, with no effects observed on Na, Mg, P, and Zn concentration. Nutrient uptake of P, Zn and Mg can also be affected by biochar, as compared to Na, K, Ca, and Fe. In this chapter, we have provided a synthesis of the impact of feedstock types and rates on growth, grain nutritional quality and yield of soybean. The chapter recommends a long-term field trial to conclusively ascertain the extent of biochar effects on soybean growth and yield, in different soil types and agro-ecological zones.
