<![CDATA[Land and plant productivity can be increased through organic fertilization and superior varieties. This study aims to determine the effect of a combination of doses of chicken manure and various varieties on the growth and production of rice plants in direct seed planting systems. An experimental trial was conducted in Gandusari Village, Gandusari District, Trenggalek Regency, from November 2021 to January 2022. The research design was a two-factor Randomized Block Design (RBD) with three repetitions. The dose of chicken manure, as the first factor, consisted of 2 kg/plot (D1), 4 kg/plot (D2), and 6 kg/plot (D3). Rice variety, as the second factor, consisted of IR-64 (V1), Ciherang (V2), and Membramo (V3). The data were analyzed using variance and continued with the Least Significant Difference (LSD) test at the 5% level if the results differed significantly. The results showed that the combination of chicken manure doses and rice varieties significantly affected plant height at 65 HST, panicle length at 65 and 79 HST, 1000 grain weight, and grain production. Variable plant height at 25 and 45 HST, number of tillers at 45 and 65 HST, number of panicles, and number of grains at 65 HST, and harvested dry unhusked grain production showed significant differences due to the doses of chicken manure. Types of rice varieties showed significant differences in plant height at 25 and 45 HST, number of panicles, and number of grains at 65 HST, as well as dry grain production per plot. The recommended treatment combination in the direct seed planting system of rice cultivation is a dose of 4 kg plot-1 and membrane variety (D2V3). Produktivitas lahan dan tanaman dapat ditingkatkan melalui pemupukan organik dan penggunaan varietas unggul. Tujuan dari penelitian adalah mengetahui pengaruh kombinasi dosis pupuk kandang ayam dan macam varietas terhadap pertumbuhan dan produksi tanaman padi pada sistem tanam benih langsung. Percobaan eksperimental telah dilaksanakan di lahan Desa Gandusari, Kecamatan Gandusari, Kabupaten Trenggalek pada Nopember 2021 sampai Januari 2022. Rancangan penelitian adalah Rancangan Acak Kelompok (RAK) dua faktor dengan tiga kali pengulangan. Dosis pupuk kandang ayam sebagai faktor pertama, terdiri atas: 2 kg/petak (D1), 4 kg/petak (D2), dan 6 kg/petak (D3). Varietas padi sebagai faktor kedua, terdiri atas: IR-64 (V1), Ciherang (V2), dan Membramo (V3). Data dianalisis dengan sidik ragam, dan dilanjutkan uji Beda Nyata Terkecil (BNT) taraf 5% apabila hasil berbeda nyata. Hasil penelitian adalah kombinasi dosis pupuk kandang ayam dan macam varietas padi berpengaruh nyata terhadap variabel tinggi tanaman umur 65 HST, panjang malai umur 65, dan 79 HST, berat 1000 butir, serta produksi gabah. Variabel tinggi tanaman umur 25, dan 45 HST, jumlah anakan umur 45, dan 65 HST, jumlah malai dan jumlah bulir umur 65 HST, serta produksi gabah kering panen menunjukkan perbedaan nyata karena perlakuan dosis pupuk kandang ayam. Macam varietas padi menunjukkan perbedaan nyata terhadap tinggi tanaman umur 25 dan 45 HST, jumlah malai dan jumlah bulir umur 65 HST, serta produksi gabah kering panen per petak. Kombinasi perlakuan yang disarankan dalam budidaya tanaman padi sistem tanam benih langsung adalah dosis 4 kg petak-1 dan varietas membramo (D2V3).]]>
