| Abstract: | Jagung pulut merupakan komoditas pangan lokal yang kaya amilopektin, namun produktivitasnya masih tergolong rendah (2–3 ton ha?¹). Salah satu upaya peningkatan produktivitas dapat dilakukan melalui budidaya organik dengan pemberian pupuk kandang ayam yang berperan sebagai pembenah tanah dan sumber hara. Selain itu, penggunaan varietas unggul
juga berkontribusi terhadap hasil dan kualitas tanaman. Penelitian ini bertujuan mendapatkan dosis optimum pupuk kandang ayam serta interaksinya dengan varietas untuk produktivitas dan kualitas jagung pulut manis. Penelitian dilaksanakan di Kebun Percobaan IPB Cikarawang Blok A Lahan Organik, Dramaga, Kabupaten Bogor. Rancangan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) faktorial dua faktor,
yakni dosis pupuk kandang ayam (0, 10, 20, 30 ton ha-1) dan varietas Paramita F1 dan Arumba dengan tiga ulangan. Hasil penelitian menunjukkan bahwa pemberian dosis pupuk kandang ayam 10 ton ha-1 secara umum meningkatkan pertumbuhan vegetatif dan komponen hasil tanaman. Dosis pupuk kandang ayam meningkatkan padatan terlarut total (PTT) sebesar 0,9–7,4%. Kadar amilopektin tertinggi pada dosis 30 ton ha-1 sebesar 70,27%. Terdapat interaksi nyata antara dosis pupuk dan varietas terhadap produktivitas. Arumba memberikan respon terbaik pada dosis pupuk 10 ton ha-1 (7,03 ton ha-1), sedangkan Paramita menunjukkan produktivitas tertinggi pada dosis 20 ton ha-1 (6,57 ton ha-1). Berdasarkan analisis regresi, dosis optimum pupuk
kandang ayam untuk varietas Paramita adalah 19 ton ha?¹, sedangkan dosis optimum untuk Arumba belum dapat ditentukan. Waxy corn is a local food commodity rich in amylopectin, yet its productivity remains relatively low (2–3 tons ha?¹). One approach to increase productivity is through organic cultivation by applying chicken manure, which functions as a soil conditioner and nutrient source. In addition, the use of superior varieties also contributes to plant yield and quality. This study aimed to determine the optimum dose of chicken manure and its interaction with varieties for the productivity and quality of waxy corn. The research was conducted at the IPB Experimental Field, Cikarawang Block A (Organic Land), Dramaga, Bogor Regency. The experiment used a factorial Randomized Complete Block Design (RCBD) with two factors, namely chicken manure dosage (0, 10, 20, and 30 tons ha?¹) and the varieties (Paramita F1 and Arumba), with three replications. The results showed that the application of 10 tons ha?¹ of chicken manure generally enhanced vegetative growth and yield components. Chicken manure also increased total soluble solids (TSS) by 0,9–7,4%. The highest amylopectin content was observed at a dose of 30 tons ha?¹, reaching 70,27%. A significant interaction was found between manure dosage and variety on plant productivity. Arumba exhibited the best response at a dose of 10 tons ha?¹, with a productivity of 7,03 tons ha?¹, and was generally more adaptive to organic cultivation. Meanwhile, Paramita showed its highest productivity at a dose of 20 tons ha?¹, reaching 6,57 tons ha?¹. Based on regression analysis, the optimum chicken manure dose for the Paramita variety was 19 tons ha?¹, while the optimum dose for Arumba could not be determined yet. |
