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.

马铃薯(Solanum tuberosum L.)-Mucuna瘙痒症间作模式对喀麦隆西部高地马铃薯农艺性状和土壤理化性质的影响
摘要在Dschang大学农学与农业科学学院教研室进行了田间试验,研究了马铃薯-Mucuna间作模式对喀麦隆西部高地马铃薯农艺性状和土壤理化性质的影响。实验设计是一个随机的完整区块,有三个重复。处理包括纯马铃薯林分(T1)、纯Mucuna林分(T2)、1:1(T3)、1:2(T4)和2:1(T5)马铃薯-Mucuna间作模式。结果表明,马铃薯-淤泥间作模式对马铃薯生长变量、土壤物理性质和相对拥挤系数没有显著影响(P>0.05)。马铃薯产量最高(24913 公斤 ha−1)和马铃薯当量产量(81513 公斤 ha−1)。1:1和1:2间作模式的总LER分别最高(2.17)和最低(1.38)。在1:1(1.46)和2:1(1.29)间作模式中,面积-时间当量比值均大于1。根据Ap和竞争比值,除了与K的1:2间作模式外,Mucuna被证明是最具攻击性和竞争力的物种,这表明在所有间作模式中都具有产量优势。1:1和2:1间作模式的C/N(13.94)和阳离子交换能力(36.12)最好 meq 100 g−1)。马铃薯单作晚疫病发生率最高(16.88%),1:2间作最低(8.05%)。因此,根据本试验的结果,可以推荐马铃薯-苜蓿间作系统采用1:1或1:2的间作模式。
