Abstract

The right dose of herbicide is able to control weeds, further increasing soybeancrop yields. This study aims to obtain oxyfluorfen herbicide doses to control weeds insoybean plantations. The doses used are: 0; 0.4; 0.8; and 1.2 kg b.a ha-1. The designused was a non-factorial randomized block design with 3 replications. The variablesobserved were: number of plant pods1, number of plant seeds1, plant seed weight1, anddry seed yield. The results showed that a dose of 0.8 kg b.a ha-1 herbicide increasedseed weight1 and yield of dry soybean seeds.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh waktu penyiangan dan kepadatan populasi jajagoan dengan jarak tanaman yang berbeda terhadap pertumbuhan dan produksi tanaman padi sawah. Penelitian ini dilaksanakan di areal persawahan petani di Desa Lawe Hijo Kecamatan Bambel Kabupaten Aceh Tenggara dimulai pada bulan Mei dan selesai pada bulan Agustus 2022. Rancangan yang digunakan adalah Rancangan Petak Terpisah faktorial dengan 2 faktor perlakuan. Faktor pertama sebagai petak utama adalah waktu penyiangan terdiri dari 5 taraf, yaitu P0 (tanpa penyiangan), P1 (waktu penyiangan jajagoan 3 minggu setelah tanam), P2 (waktu penyiangan jajagoan 6 minggu setekah tanam ), P3 (waktu penyiangan jajagoan 9 minggu setelah tanam) dan P4 (waktu penyiangan jajagoan 12 minggu setelah tanam). Faktor kedua sebagai anak petak adalah populasi jajagoan terdiri dari 4 taraf yaitu J0 (tanpa populasi jajagoan), J1 (populasi jajagoan 105 per plot dengan jarak tanam 22 cm dihitung dari tanaman utama), J2 (populasi jajagoan 210 per plot dengan jarak tanam 16 cm dihitung dari tanaman utama) dan J3 (populasi jajagoan 210 per plot dengan jarak tanam 12 cm dihitung dari tanaman utama) dan peubah amatan yang diamati adalah tinggi tanaman, luas daun tanaman, jumlah anakan tanaman padi, jumlah anakan tanaman padi produktif, jumlah gabah berisi per malai tanaman padi, jumlah gabah hampa per malai tanaman padi, berat gabah kering tanaman padi per sampel tanaman dan bobot kering jajagoan. Interaksi waktu penyiangan dan kerapatan jajagoan berpengaruh nyata terhadap tinggi tanaman pada umur 9 dan 12 minggu setelah tanam.

Abstract

Organic mulching emerges as a relevant strategy within sustainable agricultural systems.  The objective is to determine the optimal mulch dosage to suppress weeds effectively while enhancing crop growth and yield. The study was conducted within the experimental area of the Faculty of Agriculture, University Gunung Leuser, Kutacane, Aceh Province, Indonesia from September to November 2025. The experiment was arranged using a non factorial Randomized Complete Block Design comprising three treatment levels with three replications. The treatments consisted of different application rates of Ageratum conyzoides L. organic mulch, namely D0=0, D1=2, D2=4 kg m-1, which correspond to approximately 0, 20, 40 t ha-1, respectively. The variables observed included weed control percentage, ground cover, number of weed species, weed population, and fresh weed biomass. In addition, several growth parameters of sweet corn were recorded, including plant height, stem circumference, and number of leaves. Yield components measured comprised diameter, length, cob weight, kernel weight, and grain yield. The application of Ageratum conyzoides L. organic mulch at rates of 20 and 40 t ha-1 increased the percentage of weed control at 10, 20, and 30 DAP, while simultaneously reducing weed cover at 10, 20, and 30 DAP. The treatment also decreased the number of weed species at 20 and 40 DAP as well as the fresh biomass of weeds at 40 DAP. In addition, the application of Ageratum conyzoides L. organic mulch enhanced stem circumference at 30 DAP, increased the number of leaves at 10 DAP, and ultimately improved kernel yield in sweet corn.
