dc.description.abstractKedelai (Glycine max L.) adalah komoditas pangan strategis, namun produktivitasnya masih rendah akibat penurunan kesuburan tanah dan penggunaan pupuk anorganik yang berlebihan. Penelitian ini bertujuan untuk membandingkan pengaruh pemberian pupuk kandang ayam dan pupuk NPK terhadap pertumbuhan dan hasil tanaman kedelai varietas Dega pada lahan marjinal. Penelitian dilaksanakan dengan menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor perlakuan: jenis pupuk dan dosis aplikasi, serta tiga ulangan. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, jumlah polong, berat biji per tanaman, dan berat 100 biji. Hasil penelitian menunjukkan bahwa pupuk kandang ayam memberikan pengaruh yang lebih baik terhadap pertumbuhan vegetatif dan generatif dibandingkan pupuk NPK. Kompos ayam meningkatkan kualitas tanah, efisiensi penyerapan hara, dan aktivitas mikroorganisme. Meskipun pupuk NPK menunjukkan respons awal yang cepat, keunggulan jangka panjang dari pupuk organik lebih dominan. Oleh karena itu, pemupukan berbasis pupuk kandang ayam direkomendasikan sebagai strategi budidaya kedelai yang ramah lingkungan dan berkelanjutan. Soybeans (Glycine max L.) are a strategic food commodity, but their productivity is still low due to declining soil fertility and excessive use of inorganic fertilizers. This study aims to compare the effect of the application of chicken manure and NPK fertilizer on the growth and yield of soybean plants of the Dega variety on marginal land. The research was carried out using a factorial Group Random Design (RAK) with two treatment factors: the type of fertilizer and the application dose, and three replicates. The observed parameters included plant height, number of leaves, number of pods, weight of seeds per plant, and weight of 100 seeds. The results of the study showed that chicken manure had a better influence on vegetative and generative growth than NPK fertilizer. Chicken compost improves soil quality, nutrient absorption efficiency, and microorganism activity. Although NPK fertilizers show a rapid initial response, the long-term advantages of organic fertilizers are more dominant. Therefore, fertilization based on chicken manure is recommended as an environmentally friendly and sustainable soybean cultivation strategy.en_US
