Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengetahui pengaruh densitas gulma Synedrella nodiflora terhadap pertumbuhan dan hasil tanaman kedelai. Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala Banda Aceh sejak Maret – Juni 2011. Rancangan yang digunakan adalah Rancangan Acak Lengkap non faktorial dengan lima perlakuan densitas gulma yang diulang sebanyak empat kali. Densitas gulma adalah: 0, 2, 4, 6, dan 8 gulma per polibag. Peubah yang diamati adalah: jumlah cabang, diameter pangkal batang, jumlah nodula, bobot basah nodula, jumlah polong, jumlah biji, dan bobot biji per tanaman. Hasil penelitian menunjukkan bahwa densitas gulma berpengaruh terhadap bobot basah nodula dan bobot biji per tanaman. The Effects of Weed Competition of Synedrella nodiflora L. Gaertn. on Some Density to Growth and Yield of SoybeanABSTRACT .The aim of research was known the effects of weed density of Synedrella nodiflora on growth and yield of soybean. The research was conducted in Experimental Farm Agriculture Faculty, University of Syiah Kuala Banda Aceh since March up to June 2011. The experimental design was Randomized Completely Design non factorial with five treatments of weed density. Weed density were: 0; 2; 4; 6; and 8 per polybag. Variables were: number of branches, diameter of stem, number of nodules, wet  weight of nodules, number of pod, number of seed, and seed weight per plant. The result showed that weed density significantly to wet  weight of nodules and seed weight per plant.

Abstract

Application of Different Dosage of Glyphosate and Paraquat Herbicides and Their Effect on the Growth of Milky Weed (Calotropis gigantean R. Br)ABSTRACT. The study on application the different dosages of glyphosate and paraquat herbicides and their effect on the growth milky weed (Calotropis gigantean) has been conducted at Experimental station, Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh. The treatment were arranged in a completely randomized bloc design (CRD) manner with two factors. The first factor was the dosages of herbicides which were 0 kg a.i/ha, 0,4 kg a.i/ha, 0,8 kg a.i/ha, and 1,2 kg a.i/ha. The second one was the different herbicides which were glyphosate and paraquat. The result showed that the dosages of the 0,8 kg a.i/ha significantly increased the percentage of milky weed control, suppressed the height of milky weed 21 days of application (DAA), reduced the diameter of milky weed stem and decreased the dry weight of milky weed. The type of the herbicides and different dosages used interactively affected the percentage of milky weed control and the diameter of milky weed stem on 21 days of application (DAA). The paraquat herbicide applied with dosage of 1,2 kg a.i/ha significantly increased the percentage of milky weed control and suppressed the diameter of milky weed stem.
