Penelitian bertujuan untuk mengetahui pengaruh tepung cangkang telur dan pupuk kandang ayam terhadap peningkatan pH, ketersediaan hara P dan Ca Tanah Inseptisol serta serapan P dan Ca pada tanaman jagung (Zea mays L.). Dilaksanakan pada bulan Maret sampai September 2015 di Rumah Kasa Fakultas Pertanian Universitas Sumatera Utara. Percobaan menggunakan Rancangan Acak Kelompok (RAK) faktorial yang terdiri dari 2 faktor dan 2 ulangan. Faktor pertama adalah dosis pupuk kandang ayam masing-masing 0, 18,75, 37,5, dan 56,25 g /5 kg (tanah) dan faktor kedua adalah dosis tepung cangkang telur masing-masing 0, 4, 8, dan 12 g /5 kg (tanah). Hasil penelitian menunjukkan bahwa aplikasi pupuk kandang ayam memberikan pengaruh nyata meningkatkan pH , C-organik P-tersedia tanah , serapan P dan Ca serta pertumbuhan tanaman jagung. Aplikasi tepung cangkang telur hanya berpengaruh nyata meningkatkan P-tersedia tanah. Interaksi pupuk kandang ayam dan tepung cangkang telur berpengaruh nyata meningkatkan tinggi tanaman dan P-tersedia tanah.
The aim of this research was to know the effect of egg shell flour and chicken manure toward soil pH, P- availability and Ca of inceptisol with P-absorption and Ca-absorption on maize (Zea mays L.). The research had been conducted from March to September 2015 at gause, Faculty of Agriculture,University of Sumatera Utara. The method used was Randomized Block Design with 2 factors and 2 replications. The first factor was dosage of chicken manure 0, 18,75, 37,5 and 56,25 g /5 kg (soil) and second factor was dossage of chicken egg shell flour 0, 4, 8, 12 g/5 kg (soil). The result showed that chicken manure was effect significantly to increas soil pH, organic- C, P-availability and P-absorption, Caabsorption with growth of maize. Application chicken egg shell flour only was significant effect in increasing P-availibility. Interaction manure and chicken egg shell flour was significant effects on plant height and P-availibility.
