Abstract
Climate change that occurs globally in agriculture causes fail crops production, causing losses for farmers. This loss can be minimized by using rice straw mulch to reduce soil temperature and protect the soil from direct solar radiation on lettuce land. This study will examine whether treatment with rice straw mulch can affect soil temperature in lettuce land. The research was conducted at Nudira Fresh Green House PT. Nudira Sumber Daya Indonesia, Warnasari Village, Pangalengan Subdistrict, Bandung District, West Java. This research was conducted from March 1, 2022 to August 31, 2022. The data of this study used a factorial 4 x 2 Randomized Block Design with 3 replications. Factor I was the thickness of rice straw mulch 0 t ha− 1 (R0), 4 t ha−1 or 0.48 kg plot−1 (R1), 6 t ha−1 or 0.72 kg plot−1 (R2), and 8 t ha−1 or 0.96 kg plot−1 (R3) and factor II was the dose of cow manure (F1) and compost (F2) each 20 t ha−1 or 2.4 kg plot−1. The results showed that the application of rice straw mulch with the organic fertilizer has not significant effect on soil temperature in lettuce land. However, the application of rice straw mulch at a dose of 8 t ha−1 slightly better results in decreasing soil surface temperature at a depth of 0 cm, although not significantly different.
