ABSTRACT

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population, and natural resource degradation. Therefore, intercropping approach to sustainable food production is the need of hour to overcome this global issue. Field experiments were conducted under rain-fed conditions for two consecutive rainy seasons (2015/2016-2016/2017) at North Kordofan Estate, Sudan, to investigate the effects of intercropping sesame with groundnut and cowpea on its growth, yield components, and Land Equivalent Ratio (LER). The experiment consisted of nine treatments: three sole crops of sesame (S), groundnut (G) and cowpea (C) and six spatial arrangements of 1S:1G or C, 1S:2G or C, and 2S:1G or C row/s of sesame with each groundnut and cowpea. The treatments were arranged in a Randomized Complete Block Design with four replications. The results showed that intercropping had a significant (P < .05) effect on most of the parameters measured in this study. For sesame, the treatment 2S:1G (two rows of sesame alternating with one row of groundnut) gave the best number of seeds per capsules (79 seeds). For groundnut, the intercropping 1S:1G had the highest number of pods per plant (11 pods) and seed yield (7 g/plant). The spatial arrangement 1S:1G was the best pattern in terms of land equivalent ratio with 1.6. From this study, for attaining the highest total crop yield per unit area of land, where there is no crop bias and the preference is to maximize land use, the practice of planting one row of sesame alternating with one row of groundnut is recommended.

摘要

在气候变化、人口增长和自然资源退化等全球环境问题时代，可持续粮食生产是 21 世纪面临的主要挑战之一。因此，可持续粮食生产的间作方法是克服这一全球性问题的必要时间。在苏丹北科尔多凡庄园连续两个雨季（2015/2016-2016/2017）在雨养条件下进行田间试验，研究芝麻与花生和豇豆间作对其生长、产量成分和土地的影响当量比 (LER)。试验包括九个处理：芝麻（S）、花生（G）和豇豆（C）三种单一作物和1S：1G或C、1S：2G或C、2S：1G或C行的六种空间排列/ s 芝麻与每个花生和豇豆。治疗以随机完整区组设计排列，重复四次。结果表明，间作显着（P < .05 ) 对本研究中测量的大多数参数的影响。对于芝麻，处理 2S:1G（两排芝麻与一排花生交替）给出了每个胶囊的最佳种子数（79 粒种子）。对于落花生，间作 1S:1G 的单株荚数（11 个）和种子产量（7 g/株）最高。1S:1G的空间排列方式是土地当量比为1.6的最佳格局。从这项研究来看，为了获得最高的单位土地总作物产量，在没有作物偏差并且偏好最大化土地利用的情况下，建议采用一排芝麻和一排花生交替种植的做法。
