Pengaruh Pemangkasan Cabang Lateral dan Dosis Pupuk NPK terhadap Hasil Tanaman Mentimun (Cucumis sativus l.) Varietas Roberto
Abstract
Pemangkasan cabang lateral dan dosis pupuk NPK merupakan upaya untuk meningkatkan pertumbuhan dan hasil tanaman mentimun. Penelitian dilakukan dengan tujuan mendapatkan pemangkasan cabang lateral dan dosis pupuk npk terbaik terhadap hasil tanaman mentimun varietas roberto. Penelitian ini menggunakan rancangan acak kelompok faktorial dengan 12 perlakuan dan 3 ulangan, perlakuan pemangkasan dengan taraf 3 perlakuan yaitu P0 (Tanpa Pemangkasan), P1 (Pemangkasan ruas ke 1-5), P2 ( Pemangkasan ruas ke 6-10) dan Dosis Pupuk NPK dengan 4 taraf yaitu D0 ( Tanpa Pupuk), D1 (10 g/polibag), D2 (20 g/polybag), D3 (30 g/polybag). Pemangkasan memberikan pengaruh sangat nyata terhadap parameter jumlah daun (helai), jumlah bunga jantan (butir), diameter buah (cm). Dosis pupuk NPK memberikan pengaruh sangat nyata terhadap parameter panjang tanaman (cm), jumlah daun (helai), jumlah bunga jantan (butir), jumlah bunga betina (butir), jumlah buah terbentuk (buah), diameter buah (cm), panjang buah (cm), berat buah per buah (g).
Kata Kunci : Pemangkasan, Dosis Pupuk NPK, Mentimun, Pertumbuhan, HasiL
