Improving leaf chemical composition, yield, and fruit quality of Valencia orange trees through biochar soil application.

ABSTRACT: Biochar represents carbon rich material product obtained from pyrolyzing biomass and has been postulated to enhance soil health and agricultural productivity. This study examined the effect of amending the soil with biochar on yield as well as the physical and chemical properties of Valencia oranges. A control (no biochar) (T1), biochar applied at 2.0 (T2), 4.0 (T3), and 6.0 (T4) kg/tree/year were among the treatments used in a field experiment. Results showed that, when compared to control, biochar significantly (p < 0.05) increased leaf nutrient content in terms of N, P, K, and total chlorophyll content of leaves. The effect was strongest at the highest application rate of 6 kg/tree/year (T4). Biochar treatments also enhanced physical properties of fruit; the most marked improvements aga
