Abstract

Biochar is the solid product of thermal decomposition of organic materials.  Its benefits to crop and has been shown in several studies but few have dealt with its effect on soil.  This research was therefore conducted to determine the effect on soil properties and response of spring onion to different levels of biochar. An experimental research in a Randomized Complete Block Design (RCBD) with 4 replicates was used in the study. Different levels of biochar used were 0 (control), 10, 20 and 30 t-ha-1. We found out that increasing levels of biochar corresponded to decreasing values of bulk density, but increasing values of porosity, saturation point, field capacity, permanent wilting point, water holding capacity, number of plantlets per hill, computed yield per hectare and net income. No effect was found on soil temperature, weight of roots, and ROE.
