Abstract
Intercropping, the cultivation of two or more crops at the same time in the same field, is a common practice in North Korodfan of Sudan in traditional farms of smallholders. This experiment conducted in rainy season (2019/2020) to investigate the effect of intercropping on yield and yield components of cowpea (Vigan unguiculta L), sorghum (Sorghum bicolor L. Moench) and roselle (Hibiscus sabdariffa var. sabdariffa L) intercropped at different spatial arrangements. The experiment consisted of nine treatments: three sole crop of Sorghum Cowpea, and Roselle and eight spatial arrangements of 1:1, 1:2, 2:1, and 2:2 rows of Cowpea with each of Sorghum or Roselle. A randomized complete block design (RCBD) with four replications was used. The results showed that intercropping treatments had significant (P ≤ 0.05) effect on most of the parameters measured on Sorghum, Cowpea and Roselle intercropping. For sorghum: the spatial arrangements 2:2 and 1:1 had the significant highest 100-seed weight (2.9 g) and final seed yield (0.34 ton/ha). For cowpea: the treatment 2:2 had the highest number of pods per plant, 100 seed weight, and shoot dry weight for cowpea. The intercropping 2C:1S had a highest cowpea seed yield (4.2 ton/ha) compared to others spatial arrangements. For roselle the intercropping 2C:2R (two rows of cowpea alternated with two rows of roselle) had the higher number of calyx per plant (19.7) and calyx yield (9.7 g/plant) than the other spatial arrangements. From this study, the practice of planting two rows of cowpea alternating with two rows of sorghum is recommended for farmers under rain-fed sector.
套作,即在同一块土地上同时种植两种或两种以上的作物,是苏丹北Korodfan小农传统农场的一种常见做法。本试验于2019/2020年雨季,研究了不同空间安排下间作对豇豆(Vigan unguiculta L)、高粱(sorghum bicolor L. Moench)和玫瑰(Hibiscus sabdariffa var. sabdariffa L)产量及产量构成的影响。试验共设高粱、豇豆和蔷薇3个单作处理,豇豆与高粱或蔷薇各作1:1、1:2、2:1和2:2行8个空间布置。采用随机完全区组设计(RCBD),共4个重复。结果表明,套作处理对高粱、豇豆和玫瑰套作的大部分指标影响显著(P≤0.05)。高粱的百粒重(2.9 g)和最终种子产量(0.34 t / hm2)以2:2和1:1的空间布置最高。豇豆:以2:2处理单株荚果数、百粒重和茎干重最高。与其他空间安排相比,间作2C:1S的豇豆产量最高(4.2吨/公顷)。对于玫瑰,2行豇豆与2行玫瑰交替种植2C:2R的单株花萼数(19.7个)和花萼产量(9.7 g/株)高于其他空间安排。通过本研究,建议雨养区农民采用两行豇豆和两行高粱交替种植的做法。
