Abstract

Padi merupakan komoditas pangan utama di Indonesia. Penurunan produksi pangan khususnya padi akibat gulma berkisar antara 60 hingga 87%. Gulma adalah tumbuhan pengganggu yang merugikan kepentingan manusia sehingga manusia berusaha untuk mengendalikannya. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi herbisida penoxsulam+butachlor terhadap gulma, pertumbuhan dan produksi tanaman padi sawah. Penelitian ini dilaksanakan di Trimurjo, Lampung Tengah dan di Laboratorium Ilmu Gulma Fakultas Pertanian Universitas Lampung. Penelitian disusun dalam Rancangan Acak Kelompok (RAK) dengan 4 ulangan. Perlakuan terdiri atas dosis kombinasi herbisida penoxsulam+butachlor (7,5+300), (10,0+400), (12,5+500), (15,0+600) g/ha, penyiangan manual dan kontrol. Pengujian homogenitas dilakukan dengan uji Bartlett dan additifitas data dengan uji Tukey. Jika asumsi terpenuhi data akan dianalisis dengan sidik ragam. Apabila perlakuan menunjukkan perbedaan nyata maka dilakukan uji beda nilai tengah antar perlakuan dengan uji Beda Nyata Terkecil (BNT) pada taraf kepercayaan 5 %. Hasil penelitian menunjukkan bahwa kombinasi herbisida penoxsulam+butachlor pada dosis 7,5+300 sampai dengan 15,0+600 g/ha mampu mengendalikan pertumbuhan gulma total, gulma dominan Ludwigia hyssopifolia, Monochoria vaginalis, Fimbristylis miliacea, Cyperus iria sampai dengan 6 minggu setelah aplikasi (MSA), serta gulmaLeptochloa chinensissampai 3 MSA.Kombinasi herbisida penoxsulam+butachlor pada dosis7,5+300 sampai dengan 15,0+600g/ha tidak meracuni tanaman padi (Oryza sativa L.). Kombinasi herbisida penoxsulam+butachlor pada dosis 7,5+300 sampai dengan 15,0+600 g/ha tidak mempengaruhi pertumbuhan dan produksi tanaman padi sawah, tetapi keberadaan gulma menurunkan hasil Gabah Kering Giling (GKG) sehingga perlu dilakukan pengendalian.

Abstract

The experiment has been conducted in Labuhan Dalam, Tanjung Seneng, Bandar Lampung from January to June 2008. This experiment consisted of 3 subtitles that are: (1)The effect of root stock age and shading degrees on physic nut plant propagation with grafting. Is a factorial experiment (3x4) with split plot design, shading degrees as main plot consisted without shading, light shading), moderate shading, and heavy shading .Root stock age as subplot consisted 6, 8, and 10 weeks after transplanting; (2) The effect of root stock high and scion length on physic nut plant propagation with grafting. Is a factorial experiment (3x3) with randomized completely block design, the first factors were root stock high consisted 10, 15, and 20 cm from nursery medium. The second factors were scion length consisted 5 cm, 7,5 cm, and 10 cm; (3) The effect of kind of bend and IBA concentration on physic nut plant propagation with grafting. Is a factorial experiment (3x3) with randomized completely block design, the first factors were kind of bend consisted raffia rope, plastic rope, and faucet cellophane tape rope. The second factors were IBA concentration consisted 0, 1000, and 3000 ppm. The treatments were consisted 3 replication and each experiment unit consisted 10 seedlings. The result shows that (1) root stock age 8 and 10 weeks produces physic nut seedling growth better than root stock age 6 week. Physic nut seedling without shading and light shading (1 layer paranet) grow better than with moderate shading (2 layers paranet) and heavy shading (3 layers paranet); (2) Root stock high 15 cm produce physic nut seedling growth better than root stock high 10 cm and 20 cm. Length of scion 7,5 cm and 10 cm produces physic nut seedling growth better than length of scion 5 cm; (3) Plastic and faucet cellophane tape rope produce physic nut seedling growth better than raffia rope. IBA concentration 1000 and 2000 ppm produces physic nut seedling growth better than o ppm Keywords: Physic nut, root stock, seedling, grafting
