неизвестный. The research evaluated the effect of organic and conventional management on soil physicochemical indicators and performance indicators of CCN-51 cocoa (Theobroma cacao L.). A completely randomized block design was applied, with four treatments: T1 (control), T2 (compost), T3 (NPK) and T4 (compost + NPK) and four repetitions. Physical indicators were evaluated: DA10 and DA20 bulk density and resistance to penetrability RP10 and RP20 (strata from 0.00 to 0.10 m and 0.10 to 0.20 m), chemical indicators: pH, MO, P, K, Ca, Mg, Al and CEC and performance indicators: number of fruits, fruit index and yield per hectare. The results did not show differences in DA and RP in both strata; Differences were found in the indicators pH, MO, P, Al and CEC, T2 and T4 had a greater effect on pH and CEC. Differences were found in the fruit index, in addition, the highest yield per hectare was presented by T2 (1125 kg/ha), although it did not show differences. In conclusion, there were significant chemical changes, except in physical indicators and performance indicators, showing organic production as a viable alternative by not showing differences and exceeding almond yield to chemical treatment.
