  abstract = {{K}ey message {T}he determination by non-destructive measurement of biomass and leaf area is of great interest to avoid any plant degradation. {T}hese data are necessary for biomass allocation and estimation of carbon distribution in trees using functional and structural growth models such as {GREENLAB}. {O}rgan biomass and leaf area are important parameters in plant physiology and production. {T}hey are used in structural and functional plant models to simulate tree architecture, but are difficult to determine quickly. {S}tem (length and internode diameter) and leaf (length and width) dimensions for their estimation provide a non-destructive and rapid field approach. {T}his method has been applied on {K}haya senegalensis, {P}terocarpus erinaceus and {P}arkia biglobosa in {C}ote d'{I}voire. {I}nternodes and leaves of the three species were sampled in 2019 and 2020 on three categories of axis in the architecture of individuals of different ages to maximise the variability of their size. {A}ll statistical relationships of the linear models found for the estimation of organ dry and fresh biomass and leaf area were significant for all three species ({P} = 0.001). {A} single equation was sufficient to estimate the dry ({IDM}) and fresh ({IFM}) biomass of the internodes, the dry ({LDM}) and fresh ({LFM}) biomass of the leaves and the leaf area ({LA}) from the dimensions of the internodes ({V}olume: {VL}) and leaves ({N}umber of primary leaflets: {NL}t, length: {LL}t{L} and width: {LL}t{W} of the largest primary leaflet, number of secondary leaflets: {NS}e{L}t, length: {LS}e{L}t{L} and width: {LS}e{L}t{W} of the largest secondary leaflet). {T}he relationship between the estimates and organ dimensions were defined by the following linear equations: {IDM} = 0.45 x {VL} + 0.02, {LDM} = 0.004 x {NL}t x {L}t{L} x {L}t{W} + 0.07 and {LA} = 0.83 x {NL}t x {L}t{L} x {L}t{W} for {K}haya senegalensis; {IDM} = 0.33 x {VL} + 0.38, {LDM} = 0.4 x {NL}t x {L}t{L} x {L}t{W} - 0.64 and {LA} = 0.74 x {NL}t x {L}t{L} x {L}t{W} + 0.15 for {P}terocarpus erinaceus then {IDM} = 0.47 x {VL} + 0.44, {LDM} = 0.44 x {NS}e{L}t x {LS}e{L}t{L} x {LS}e{L}t{W} x {NL}t + 0.94 and {LA} = 0.13 x {NS}e{L}t x {LS}e{L}t{L} x {LS}e{L}t{W} x {NL}t + 14.64 for {P}arkia biglobosa. {T}his method can be applied to estimate the organ biomass and {LA} of species of the same family as the target species in an agroforestry system.},
