Abstract
Suitable management techniques are required to improve soil nutrient availability and crop yield. This study evaluated biochar particle sizes (< 2 mm) showed the maximum 13, 17, 6 and 17% increase in bundle weight, straw yield, grain yield and thousand grain weight, respectively, and 27, 43 and 18% increase in soil mineral nitrogen (N), phosphorus (P) and potassium (K) status, respectively, compared to no Biochar plots. The Bizote-N inoculation improved the grain yield by 4%. Combination of Bizote-N and the biochar smallest particle size (< 2 mm) resulted in more mineral N content. The extractable K was highest at < 2 mm particle size and no biofertilizer treatment followed by Bizote-N inoculation. It was concluded that the Biozote-N performance was consistent with the lowest biochar particle size (< 2 mm) for enhanced lentil yield and soil fertility
