A field experiment was conducted to examine the yield <br>performances and intercropping efficiencies of sweet corn and okra planted in a young rubber plantation. The treatments were arranged <br>in Randomized Complete Block Design (RCBD) with three replications. The treatments ratios were 20% okra + 80% sweet corn (strip <br>and strip relay intercropping) with sole okra and sweet corn as the control. This consists of strips intercropping (okra and sweet corn <br>planted on the same date), strip relay intercropping (sweet corn planted 4 weeks after okra planting), sole okra and sole sweet corn. The <br>highest yield of okra was obtained from strip relay intercropping while the highest yield of sweet corn was produced from the pattern of <br>strip intercropping. However, the economic analysis showed that the strip intercropping recorded the maximum gross margin and costbenefit ratio of RM 17,733.20 ha-1 and 2.09, respectively. Immature rubber growth was unaffected by intercropping with sweet corn <br>and okra crops. Strip intercropping not only resulted in the higher land equivalent ratio (1.29), but also area time equivalent ratio, % land <br>saved and monetary advantage index of 1.14, 22.28% and RM 7,583.50 ha-1, respectively compared with strip relay intercropping. The <br>highest assessment of intercropping based on relative crowding coefficient was recorded by strip intercropping with 4.56. With regard <br>to competition between the intercrops, okra was a more dominant species as measured by the positive value of aggressivity. However, <br>strip intercropping was indicated the lowest competitive ratio than the strip relay intercropping. Thus, this intercropping pattern could be <br>recommended to the farmers for adoption.</p>}, number={5}, journal={Emirates Journal of Food and Agriculture}, author={Samsuri, Shampazuraini and Mohammad Yusoff, Martini and Ramlan, Mohd Fauzi and Sulaiman, Zulkefly and Buda, Mark and Md Isa, Isharudin}, year={2022}, month={Jun.} }
