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.

Physiologycal Performance Comparison of Rice from Local and National Genotype to Overcome Drought ABSTRACT. Rice (Oryza sativa) is a major food commodity in the world that affected by global warming. It can be seen from crop harvest failure due to drought in many parts of the world. It is necessary to promote Land Race which has adapted to specific conditions, this is to strengthen national seed systems. This study aimed to compare the character of national varieties with local varieties that allow for superior varieties such as Cirata, Inpari 7, Ciherang, IR 64, Situ Patenggang, Situ Bagendid, Limboto and Towuti as a control and compare with 11 local genotypes (Rom Mokot, Pade Mas, Salah Manyang Ru, Bo Santeut, Si Gupai, Si Kuneng, Pade Barcelona, Sanbei, Ramoes, Si Puteh and Si Tandun) were germinated in a solution of PEG 6000 2,5% (25 grams / liter of solution). The results showed that local genotype have characters that can match with the national release varieties in the benchmark vigor reflected in germination rate, simultaneity germination and T50. Local genotype Sitandun, Si Puteh, Ramos, Sanbe, Pade Barcelona, Bo Santeut, Si gupai and Pade Mas reached 50% germination even faster than the national release varieties except Towuti and Limboto. For simultaneity germination, local genotypes Pade barcelona and Sanbe equal to Towuti, Ciherang and Inpari 7. For germination rate, local genotype Pade Mas, Pade Barcelona, Sanbe, Ramos, and Siputeh equal to Towuti, Inpari 7, Ciherang and Situ Patenggang.

Abstract

            The study on application of different dosages of paraquat herbicide on different ages of milkyweed (Calotropis gigantea R. Br) have been conducted in Experimental Station, Agriculture Faculty, Syiah Kuala University, Darussalam Banda Aceh. The treatments were arranged in a Completely Randomized Design (CDR) with two factors. The first factor was dosages of herbicide which were 0; 0,1; 0,2; 0,3; and 0,4 kg active ingredient (a.i.) ha-1. The second factor was ages of  C. gigantea R. Br which were 30 days, 45 days and 60 days after planting. The result showed that dosage of 0,3 kg i.a. ha-1 significantly increased the percentage of C. gigantea R. Br and decreased the dry weight shoot and root of C. gigantea R. Br. The youngest stage of C. gigantea R. Br was more effective to be controlled, and had a lower dry weight shoot and root than the oldest one. The paraquat herbicides applied with dosages of 0,3 kg a.i. ha-1 on 30 days after planting increased the percentage of C. gigantea R. Br, and  reduced shoot and root dry weight of C. gigantea R. Br.

Weed controling is one of some step to attempt weed growth, but does not have any negatif effect to cultivated plants. The precense of weed among the cultivated plants can lead to competition in term of competing for waters, nutrients, lights and growing space. This research is aims to determine the effect of some weed mulch for weed alteration on soybean. This research was held in umpeet Village, Subdistric of Krueng Barona Jaya, Aceh Besar Regency and Weed Science Laboratory, Faculty of Agriculture, University of Syiah Kuala. The materials used is soybeans seed variety of Dega-1 that collected from Balai Penelitian Tanaman Aneka Kacang dan Umbi (Balitkabi) Malang. This research using Randomize Block Design (RBD) factorial pattern 2x4 repeated 3 times. The result of this research showed that the mulch?s species and dose were not affected by the number of weeds populations and species. There was an interaction between the mulch species and dose on weeds species number during 56 days after it was planted.

Abstrak. Penelitian ini bertujuan untuk melihat perubahan komposisi gulma akibat jenis dan dosis herbisida oksifluorfen dan pendimethalin serta interaksi antara keduanya pada tanaman kedelai. Penelitian ini dilaksanakan pada bulan Mei sampai Agustus 2019 di Desa Rumpeet dan Laboratorium Ilmu Gulma Fakultas Pertanian Universitas Syiah Kuala. Rancangan penelitian yang digunakan adalah RAK pola faktorial 2 x 5 dengan 3 ulangan. Faktor yang diteliti yaitu jenis herbisida yang terdiri dari 2 taraf (Oksifluorfen dan Pendimethalin) dan dosis herbisida yang terdiri dari 5 taraf (Kontrol, 0,5, 1, 1,5 dan 2 kg b.a ha-1). Hasil penelitian menunjukkan bahwa jenis herbisida berpengaruh terhadap persentase pengendalian gulma, jumlah spesies gulma dan bobot kering gulma, perlakuan terbaik dijumpai pada jenis herbisida oksifluorfen. Dosis herbisida berpengaruh terhadap persentase pengendalian gulma, persentase penutupan gulma, jumlah spesies gulma, jumlah populasi gulma dan bobot kering gulma, perlakuan terbaik dijumpai pada dosis herbisida 0,5 kg b.a ha-1. Terdapat interaksi antara jenis dan dosis herbisida terhadap persentase pengendalian gulma, perlakuan terbaik dijumpai pada kombinasi herbisida oksifluorfen dengan dosis 1,5 kg b.a ha-1. Terdapat perubahan komposisi gulma akibat aplikasi herbisida dari Cleoma viscosa (SDR=19,27%) yang dominan menjadi gulma Cyperus rotundus (SDR=46,33%).Effect of Oxyfluorphene and Pendimethalin Herbicide Dosages on Change in Weed Composition at Soybean Plants (Glycine max L. Merrill)Abstract. This research aims to determine change in weed composition due to the types and dosages of the oxyfluorphene and pendimethalin herbicides and the interactions between the two on soybean plants. The research was conducted in May to August 2019 in the Rumpeet Village and the Weed Science Laboratory, Faculty of Agriculture, Syiah Kuala University. The design used was a Randomized Factorial Block Design 2 x 5 with 3 replications. The factors observed were the type of herbicide consisting of 2 levels (Oxyfluorphene and Pendimethalin) and the dosages of the herbicide consisting of 5 levels (Control, 0,5, 1, 1,5 and 2 kg a.i ha-1). The results showed that the type of herbicide significantly affects the percentage of weed control, the number of weed species and weed dry weight, the best treatment was found at a type of oxyfluorphene herbicide. Herbicide dosages significantly affects the percentage of weed control, the percentage of weed cover, the number of weed species, the number of weed populations and weed dry weight, the best treatment was found at a dosages of herbicide 0,5 kg a.i ha-1. There is an interaction between the types and dosages of herbicides on the percentage of weed control, the best treatment is found in a combination of herbicide oxyfluorphene with a dosages of 1,5 kg a.i ha-1. There was a change in the composition of weeds due to the application of herbicide from Cleoma viscosa (SDR = 19,27%) which predominantly became weed Cyperus rotundus (SDR = 46,33%).
