Abstract

Ultraviolet-B (UV-B) exposure and microclimate shifts can affect pod set and seed filling in peanut, yet field evidence comparing UV-blocking versus conventional plastic shading within integrated cultivation packages remains limited, especially for linked canopy–rhizosphere responses and plot yield. Six technology packages (A–F)—a farmer baseline package or the Balitkabi recommendation (Indonesian Legume and Tuber Crops Research Institute, Malang), combined with no shade, conventional plastic, or UV-blocking plastic—were arranged in a randomized block design (hereinafter referred to as RBD) with 6 treatments × 4 blocks. Microclimate was recorded at 14, 21, 28, 35, and 42 days after planting (hereinafter referred to as DAP), including UV-B irradiance (µW cm−2), PPFD (µmol m−2 s−1), and relative humidity (%) at 08:00, 12:00, and 16:00, plus air and rhizosphere temperature (°C) at 05:00 and 13:00. UV-B peaked at midday and treatment separation was clearest at 12:00; at 42 DAP, unshaded A–B reached 6,727.5–6,592.5 µW cm−2, while UV-blocking shade reduced UV-B to 3,967.75 µW cm−2 (package D). Shaded plots were warmer at 13:00 than unshaded plots (14 DAP: 34.05–34.90 vs 31.02–31.32 °C), indicating thermal trapping, whereas humidity was mainly time-driven and not significantly different among packages. Package F had the highest yield components (total pods 20.18 plant−1; filled pods 17.70 plant−1; seeds 29.15 plant−1), but plot yield (filled-pod and dry-seed weight per plot) was not significant at LSD 5%. These results suggest optimizing shade configuration/ventilation to limit midday heat accumulation and improving water–stand uniformity during reproductive filling to convert microclimate gains into yield.
