Abstract

The intercropping system has become increasingly important due to the limited availability of agricultural land and the growing population. Sweet corn is one of the potential crops for intercropping; however, its compatibility with companion plants varies among genotypes. This study analyzed the canopy diversity of 10 sweet corn genotypes and their impact on temperature, humidity, and light intensity. The research was conducted at the Pasir Kuda Experimental Station, Bogor Agricultural University, from June to August 2024, using ten hybrid sweet corn genotypes in a randomized complete block design with three replications. Each genotype was planted in plots measuring 3.75 m², with a 25 cm × 75 cm spacing, resulting in 30 plants per bed. Principal Component Analysis (PCA) and hierarchical analysis identified three clusters of genotypes based on ten morphological traits. The first cluster included “Verona”, “Talenta”, “Paragon”, SM12 x SB13, “Exotic”, and “Secada”. The second cluster consisted of “Arinta”, SB8 x SM6, and SM12 x SM1, while the third cluster included SM1 x SM9. Temperature and humidity measurements revealed significant differences among clusters, influencing photosynthetic efficiency and yield potential. Denser canopies exhibited lower temperatures, higher humidity, and reduced light intensity, whereas more open canopies displayed higher temperatures, lower humidity, and increased light intensity. The study also analyzed cob weight, length, and diameter, as well as critical factors for yield potential and photosynthetic efficiency. Based on the results, genotypes with denser canopies from Cluster One (“Verona”, “Talenta”, “Paragon”, SM12 x SB13, “Exotic”, and “Secada”) are recommended for intercropping with cayenne peppers due to their favourable microclimate compatibility.

Abstract

The study of adaptation mechanisms in cayenne pepper under shade stress is crucial for further exploration. Cayenne pepper is one of the primary commodities that play an essential role in the agricultural industry. This research focuses on the adaptation of morphological, physiological, and secondary metabolite characteristics of cayenne pepper under shading treatments, while also examining the role of microclimate on these characteristics. The study was conducted from August 2023 to February 2024 at the Leuwikopo experimental field of Bogor Agricultural University, using five genotypes of cayenne pepper cultivated under two shading treatments: 0% and 50% shading, achieved using shade netting. The results showed that among the five genotypes tested, shade-loving genotypes, such as “Bonita,” and shade-tolerant genotypes, like “Ori 212,” displayed a greater morphological response in terms of plant height and canopy width under 50% shade compared to the other genotypes. In terms of yield traits, shade-tolerant genotypes, such as “Ori 212”, exhibited the highest fruit weight per plant under a 50% shading treatment compared to the other genotypes. Regarding physiological responses, specifically pigment content, no significant effect of shading treatment was observed. However, in terms of secondary metabolite content, all genotypes responded by increasing total phenol and flavonoid levels when grown in unshaded conditions or under full light intensity. This study provides insights into the adaptive responses of various cayenne pepper genotypes to microclimatic conditions in their growing environment.
