The aim of this study is to evaluate the effect of biochar on tomato production under controlled conditions. Trials were installed using a complete randomized block design (CRD) with 5 replications of 4 treatments: T0 (0%); T1 (8%); T2 (12%) and T3 (16%). During plant growth, parameters including height, diameter, number of leaves, number of fruits and plant biomass were collected. Plants obtained from pot that received biochar (T1, T2 and T3) were higher than plant without biochar application (T0). The average value of tomato fruits per treatment indicated that plants from treatment T1 displayed a greater number of fruit per plant with an average of 12±2; whereas plants in control treatment, T0 did not have fruit. Plants from treatments T2 and T3 showed a number of fruit between control and T1. Soil chemical analysis indicated that exchangeable cation, CEC, pH, SOM, total nitrogen and C/N ratio were higher than in the initial soil. Regarding microbial activity, various treatments did not have a significant effect on soil enzymic activity. The recovery of waste as a source of organic materials is a practice to be encouraged in urban horticulture and in open field to restore soil fertility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
