Abstract
Abstract A field experiment was conducted at the teaching and research farm of the Faculty of Agronomy and Agricultural Sciences of the University of Dschang to investigate the effects of potato–Mucuna intercropping pattern on the agronomic performances of potatoes and the soil physicochemical properties in western highlands of Cameroon. The experiment design was a randomized complete block with three replications. The treatments included a pure potato stand (T1), pure Mucuna stand (T2), 1:1 (T3), 1:2 (T4), and 2:1 (T5) potato–Mucuna intercropping patterns. The results revealed that potato–Mucuna intercropping patterns had no significant effect (P > 0.05) on potato growth variables, soil physical properties, and the relative crowding coefficient. The highest potato yield (24,913 kg ha−1) and potato equivalent yield (81,513 kg ha−1) were obtained from the 1:1 intercropping pattern. The highest total LER (2.17) and the lowest (1.38) were obtained with 1:1 and 1:2 intercropping patterns, respectively. Area time equivalent ratio values were greater than 1 in 1:1 (1.46) and 2:1 (1.29) intercropping patterns. Mucuna proved to be the most aggressive and competitive species according to Ap and competitive ratio values except for the 1:2 intercropping pattern with K indicating a yield advantage in all intercropping patterns. 1:1 and 2:1 intercropping patterns gave the best C/N (13.94) and cation exchange capacity (36.12 meq 100 g−1), respectively. Late blight incidence was highest (16.88%) on potato sole crop stand and lowest (8.05%) on 1:2 intercropping pattern. Therefore, based on the findings of this experiment, 1:1 or 1:2 intercropping pattern could be recommended in potato–Mucuna intercropping system.
