Abstract

Penelitian ini menggunakan desain penelitian Rancangan Acak Kelompok Faktorial dengan uji BNT pada tingkat signifikan 5%. Perlakuan eksperimental menggunakan dua faktor, yaitu bobot umbi kentang (B) dan metode menempatkan benih di lubang tanam (K). Faktor perlakuan pertama adalah bobot umbi bibit (B) empat (tingkat yang terdiri dari B1 = 25-30 gram, B2 = 35-40 gram, B3 = 45-50 gram dan B4 = 55-60 gram. Faktor perlakuan kedua adalah metode penempatan bibit di lubang tanam (K) empat level terdiri dari K1 = posisi umbi membentuk sudut 00, K2 = posisi umbi membentuk sudut 300, K3 = posisi umbi membentuk sudut 600 dan K4 = posisi umbi membentuk sudut 900. Berdasarkan uji lanjut tes BNT dengan taraf 5%, perlakuan tunggal bobot umbi 45-50 gram dan perlakuan tunggal letak umbi 30o berbedanyata dengan perlakuan lainnya terhadap jumlah umbi. kombinasi dari dua perlakuan bobot umbi dari 55-60 gram ditempatkan pada metode penempatan letak umbi 900 berbeda nyata dengan perlakuan lainnya terhadap jumlah batang. Perlakuan bobot umbi 60o berbeda nyata dengan perlakuan lainnya terhadap bobot basah. Kombinasi bobot umbi 55-60 gram pada letak umbi 90o terdapat interaksi pada variabel bobot basah.. Kesimpulan dari penelitian adalah perlakuan tunggal bobot umbi 45-50 gram dengan perlakuan tunggal letak umbi 300 berpengaruh terhadap jumlah umbi. Kombinasi bobot umbi 55-60 gram ditempatkan pada letak umbi 60o menghasilkan jumlah umbi optimum, tetapi kombinasi dua perlakuan 55-60 gram yang ditempatkan letak umbi 900 terdapat interaksi pada variabel bobot basah.

Abstract

Adnan A. 2019.  Effectiveness of organic mulch and household waste poc against growth and yield of yellow potato bulb (Solanum tuberosum L) in Curup. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 305-317. Palembang: Unsri Press. The study was conducted mid-June 2018 to December 2018, in the Air Rambai Village, Curup Tengah District, Rejang Lebong District. At an altitude of 600 m above sea level. Liquid organisms (POC) fertilizers can be utilized directly by plants, environmentally friendly, economically household waste materials are easily available and can be used in the process of making raw materials for liquid fertilizer. mulch as ground cover in maintaining soil moisture, reducing weeds, direct sunlight that affects roots and potato tubers. POC and organic mulch are natural resources as raw materials are easily obtained in Rejang Lebong Regency. Factorial Randomized Group Design, ie organic mulch (M), M1 = No mulch, M2 = banana leaf, M3 = rice husk, M4 = coffee husk. POC (O), namely: O0 = No poc, O1 = poc 50 ml/liter of water, O2 = poc 75 ml/liter of water and O3 = poc 100 ml / liter of water. Amount of 288 potato seeds. The results of variance of poc (O) and mulch (M) have a very significant effect on variables: number of main stems, number of shoots, wet weight, and stem diameter. Furthermore, the combination treatment of coffee with a dose of 50 ml/l of liquid fertilizer up to 75 ml/l of water has a very significant effect on the variables: number of main stems, plant height, number of shoots, wet weight and tuber diameter. The combination treatment of rice scoop mulch and liquid fertilizer 100 ml/ l of water is there interaction with wet weight and tuber diameter Both treatments (there are interactions with variables: plant height, number of main stems, number of shoots, wet weight and tuber diameter).Conclusion: The use of rice scoop mulch can increase wet weight and tuber tuber diameter, POC 75 ml/l water to the number of shoots, tuber wet weight. The combination of coffee scaffolding mulch with a dose of poc 50-75 ml/l of water has an effect on the growth of plant height, number of shoots and main stems. Combination of rice scam mulch and 100 ml/l poc of water there is interaction with wet weight and tuber diameter.Keywords: liquid fertilizer, mulch, potatoes
