Effect of manure-based biochar amendment on soil chemical properties, total enzymic activities and tomato growth performance in acidic soil under controlled conditions

The aim of this study is to evaluate the effect biochar on tomato production under controlled conditions. Trials were installed using a complete randomized block design (CRD) with 5 replications 4 treatments: T0 (0%); T1 (8%); T2 (12%) and T3 (16%). During plant growth, parameters including height, diameter, number leaves, fruits biomass collected. Plants obtained from pot that received (T1, T3) higher than without application (T0). average value per treatment indicated plants displayed greater fruit an 12±2; whereas in control treatment, did not have fruit. treatments showed between T1. Soil chemical analysis exchangeable cation, CEC, pH, SOM, total nitrogen C/N ratio initial soil. Regarding microbial activity, various significant soil enzymic activity. recovery waste as source organic materials practice be encouraged urban horticulture open field restore fertility. Key words: Biochar, quality, tomato, yield.
