Abstract

This study investigates the effects of bird netting treatment on autumn-sown naked oats (Avena sativa L.) in cultivation-limited areas over three years (2022-2024) in Jeonbuk Province, Korea. The research focuses on evaluating the thermal insulation effects of bird netting during the wintering period (late December to mid-February) and its impact on post-winter growth characteristics, agronomic traits, and yield. Naked oats were sown in late fall in upland fields by drill seeding in the Jeonbuk Wanju region and overwintered under microfiber bird netting (PE) treatment with 0, 1, or 2 layers applied to two oat varieties, ‘Joyang’ and ‘Daeyang’, respectively. The sowing amount was 19 kg per 10 a, with a standard fertilizer level of 7.2 kg (N-P-K=15-14-6) per 10 a. After wintering, we investigated the growth, agronomic, and yield characteristics of naked oats. Bird netting treatment increased minimum temperatures within the covered area, particularly from late December to mid-January, compared to untreated controls. Post-winter growth assessments indicated a reduction in the dead leaf ratio across both varieties under netting, with significant improvements in ‘Joyang’ and ‘Daeyang.’ Additionally, bird netting treatment advanced heading and maturity dates, with ‘Joyang’ and ‘Daeyang’ heading up to 5 days and maturing up to 12 days earlier under double-layer netting. Yield characteristics also improved, with a significant increase in the yield of ‘Joyang’ under double-layer netting, from 208 kg per 10 a (control) to 420 kg per 10 a. Although not statistically significant, ‘Daeyang’ showed a yield increase from 293 kg per 10 a (control) to 473 kg per 10 a under similar conditions. These findings suggest that bird netting treatment can effectively mitigate abnormal winter weather effects, enhance early growth stability by reducing plant mortality, and potentially prevent bird damage during the seedling stage. Consequently, bird netting may serve as a reliable production technology, contributing to the expansion of oat cultivation in marginal areas.
