Assessment of Sweetcorn Hybrids Under Sweetcorn/Chilli Pepper Intercropping in West Java, Indonesia

D. Ruswandi, J. Supriatna, N. Rostini and E. Suryadi

Objective: Sweetcorn/chilli pepper intercropping is commonly applied to increase yield and profit by farmers in West Java, Indonesia. Methodology: An experiment was set up in Kutamandiri-Sumedang, West Java from January up to April, 2015 to select new sweetcorn hybrid and their parental lines for intercropping with chilli pepper. To evaluate the genetic materials, they were arranged by split plot design. This was replicated twice with the main plot consisting of four cropping systems, whereas, the subplots were 38 sweetcorn genotypes. Results: The result showed that parental line of MSR 17.2.3 is the best combiner for plant height, while SR 17 is the best combiner for maturity and ear weight per plant. The best combinations for high yield in both sole cropping and intercropping are MSR 12.6.7xSR 4 and MSR 25.5.1xSR 17. However, MSR 17.6.7xSR 17 were the best hybrid for intercropping based on land equivalent ratio, competitive ratio and stress tolerance index analysis. Conclusion: It is also identified that MSR 17.6.7xSR 17 was suitable for sweetcorn/chilli pepper intercropping for the following aspects including higher yield than sweetboy check variety both in sole and intercropping system, moderately level of competition ratio against chilli pepper, low tolerance index to chilli pepper and higher productivity in 2:1 sweetcorn/chilli pepper intercropping system.
