Tanaman selada (lactuca sativa l.) merupakan salah satu tanaman hortikultura yang memiliki bentuk menarik dan bernilai gizi tinggi. oleh karena itu perlu dilakukan suatu upaya agar produksi tanaman selada dapat meningkat. upaya yang dapat dilakukan yaitu dengan pemanfaatan mulsa jerami padi dan pupuk organik seperti pupuk kotoran sapi dan pupuk kompos. penelitian ini bertujuan untuk mengetahui pengaruh pemberian mulsa jerami padi dan pupuk organik serta interaksi antara keduanya terhadap pertumbuhan dan produksi tanaman selada. penelitian ini dilaksanakan di lahan nudira fresh green house, pt. nudira sumber daya indonesia, desa warnasari, kecamatan pangalengan, kabupaten bandung, jawa barat. penelitian ini menggunakan rancangan acak kelompok faktorial dengan 3 ulangan. faktor pertama adalah dosis mulsa jerami padi terdiri dari 4 taraf yaitu tanpa mulsa jerami padi, mulsa jerami padi 4 ton ha-1, mulsa jerami padi 6 ton ha-1, dan mulsa jerami padi 8 ton ha-1. faktor kedua adalah jenis pupuk organik terdiri dari 2 taraf, yaitu pupuk kotoran sapi 20 ton ha-1 dan pupuk kompos 20 ton ha-1, sehingga terdapat 8 kombinasi perlakuan dan 24 unit percobaan. parameter yang diamati dalam penelitian ini yaitu: analisis kimia tanah awal, analisis pupuk organik, tinggi tanaman (cm), jumlah daun (helai), bobot basah per tanaman (g), bobot basah per plot tanaman (g), dan analisis kimia tanah akhir. hasil penelitian menunjukkan perlakuan dosis mulsa jerami padi berpengaruh nyata terhadap parameter tinggi tanaman 14 hst, namun berpengaruh tidak nyata terhadap parameter jumlah daun dan produksi tanaman selada. perlakuan mulsa jerami padi yang memberikan hasil terbaik terdapat pada dosis 8 ton ha-1. perlakuan jenis pupuk organik berpengaruh nyata terhadap tinggi tanaman 35 hst, namun berpengaruh tidak nyata terhadap parameter jumlah daun dan produksi tanaman selada. perlakuan jenis pupuk organik yang memberikan hasil terbaik terdapat pada jenis pupuk kotoran sapi. hasil analisis ragam menunjukkan bahwa tidak terdapat interaksi antara pemberian mulsa jerami padi dan pupuk organik terhadap fase pertumbuhan dan produksi tanaman selada.

Lettuce (Lactuca sativa L.) is a horticultural plant that has an attractive shape and high nutritional value. Therefore, efforts need to be made to increase lettuce production. Efforts that can be made are by using rice straw mulch and organic fertilizers such as cow dung and compost. This research aims to determine the effect of rice straw mulch and organic fertilizer and the interaction between the two on the growth and production of lettuce plants. This research was carried out on the land of Nudira Fresh Green House, PT. Nudira Indonesian Resources, Warnasari Village, Pangalengan District, Bandung Regency, West Java. This research used a factorial Randomized Block Design with 3 replications. The first factor is the dosage of rice straw mulch consisting of 4 levels, namely without rice straw mulch, 4 tons of rice straw mulch ha-1, 6 tons of rice straw mulch ha-1, and 8 tons of rice straw mulch ha-1. The second factor is that the type of organic fertilizer consists of 2 levels, namely cow dung fertilizer 20 tons ha-1 and compost fertilizer 20 tons ha-1, so there are 8 treatment combinations and 24 experimental units. The parameters observed in this research were: initial soil chemical analysis, organic fertilizer analysis, plant height (cm), number of leaves (strands), wet weight per plant (g), wet weight per plant plot (g), and soil chemical analysis end. The results of the research showed that the treatment dose of rice straw mulch had a significant effect on plant height parameters at 14 DAP, but had no significant effect on the parameters of leaf number and lettuce plant production. The rice straw mulch treatment that gave the best results was at a dose of 8 tons ha-1. The type of organic fertilizer treatment had a significant effect on plant height at 35 DAP, but had no significant effect on the parameters of leaf number and lettuce plant production. The type of organic fertilizer that gives the best results is cow dung fertilizer. The results of the analysis of variance showed that there was no interaction between the provision of rice straw mulch and organic fertilizer on the growth phase and production of lettuce plants.
