Abstract

A field experiment was conducted at the Horticulture farm of Paklihawa Campus, Institute of Agriculture and Animal Science, Rupandehi district to observe the effect of biochar from different origin on physio-chemical properties of soil and yield of garden pea (Pisum sativum L.) and evaluate them. The experiment was laid out in a Randomized Complete Block Design with four replications. A set up constituted of various treatments viz. rice husk biochar, poultry manure biochar, sheep manure biochar, farm yard manure biochar and wood biochar along with the control group. Results showed that number of pod/plant, number of seed/pod and biomass (ton/ha) were significantly affected by application of biochar of different origin. Application of rice husk biochar had higher effect on number of pod/plant, no of seed/pod, biomass (ton/ha) and green pod yield (ton/ha). Biochar of Poultry manure and of sheep manure had almost similar effect on soil nitrogen as of other types of biochar, while higher effect on soil phosphorus and potassium as compared to other biochar. Biochar of sheep manure had higher organic matter content and carbon percentage in soil than all other application of biochar. Application of all types of biochar showed highly significant results on bulk density and particle density. It was found that biochar of rice husk had greater particle density 2.61 g/cc and all the application had decreased bulk density except that of biochar prepared from wood. Thus, the soil where biochar was applied was found to be of better quality than that of the controlled one where no biochar was used. These results suggest that biochar could be one of the best options in poor quality soil and where burning practices are mostly adopted for cleaning the field.
