THE INFLUENCE OF TRANSPLANTING DATE ON THE YIELD OF SWEET CORN IN THE AGROECOLOGICAL CONDITIONS OF SARAJEVO FIELD

Abstract

Sweetcorn (Zea mays var. saccharata) is a subspecies of corn that is recognized by its soft, juicy, and sweet kernels. The primary challenge in cultivating this species is its limited technological maturity, which results in a short harvest season. To meet the increasing demand for this species from consumers and extend the harvesting season, producers have recently implemented various agrotechnical measures. This study aimed to research the impact of different transplantation dates on sweet corn yield. Field research was conducted at the experimental field of the Faculty of Agriculture and Food in Sarajevo, located at Butmir, from 2024 to 2025. The study encompassed three distinct transplantation dates, spaced ten days apart. During the technological harvest, we recorded plant height, dehusked ear length, dehusked ear mass, ear length, ear mass, and yield. The research results indicate that the planting date during the two years (2024 and 2025) significantly affected the ear yield, while it did not have a statistically significant effect on other traits. More specifically, the ear yield (dehusked and husked) was the highest in the second transplantation dates (14,056 and 8,818 kg ha⁻¹) compared to the first (10,258 and 7,027 kg ha⁻¹) and the third (11,643 and 7,628 kg ha⁻¹). The year of the research also showed a significant influence on the yield components. Changes in research traits were a consequence of different weather conditions in the research years.
