Abstract

Produksi jagung yang menurun pada tahun 2023 dibanding tahun 2022 mengakibatkan impor jagung meningkat tajam. Upaya meningkatkan produksi jagung dapat dilaksanakan dengan aplikasi pupuk majemuk berimbang. Penelitian dilakukan di lahan percobaan Fakultas Pertanian Universitas Brawijaya di Jatikerto, Kecamatan Kepanjen, Kabupaten Malang. Rancangan penelitian menggunakan rancangan acak kelompok (RAK) yang terdiri dari 7 perlakuan dengan 3 ulangan. Perlakuan terdiri atas: 1) P0=kontrol (tanpa pemupukan), 2) P1=100% pupuk dasar, 3) P2=urea 400 kg/ha+rock phosphate 150 kg/ha+KCl 75 kg/ha, 4) P3=urea 400 kg/ha+pupuk fosfat uji 150 kg/ha+KCl 75 kg/ha, 5) P4=urea 400 kg/ha+pupuk fosfat uji 200 kg/ha+KCl 75 kg/ha, 6) P5=urea 400 kg/ha+pupuk fosfat uji 250 kg/ha+KCl 75 kg/ha, 7) P6=urea 400 kg/ha+pupuk fosfat uji 300 kg/ha+KCl 75 kg/ha. Data dianalisa anova dan dilanjutkan dengan uji DMRT taraf 5%. Selanjutnya dilakukan analisa korelasi dan regresi untuk melihat hubungan dan pengaruh antar parameter. Hasil penelitian menunjukkan Aplikasi pupuk anorganik berbasis fosfat secara signifikan mampu meningkatkan pertumbuhan tanaman (tinggi tanaman, jumlah daun, diameter batang), produksi jagung (panjang dan diameter tongkol, berat kering pipilan), dan serapan unsur hara tanaman. Dosis aplikasi pupuk fosfat Uji (~300 kg/ha) mampu meningkatkan serapan hara tanaman dan produksi jagung, sedangkan dosis aplikasi (200-250 kg/ha) pupuk fosfat uji merupakan dosis pupuk optimal dalam meningkatkan kandungan P total dan P tersedia tanah. Hubungan antara serapan P dengan produksi tanaman jagung memiliki hubungan yang positif dengan tingkat keeratan yang kuat yang berarti dengan serapan hara P yang tinggi dapat meningkatkan produksi tanaman jagung.ABSTRACTCorn production decreased in 2023 compared to 2022, resulting in corn imports increasing sharply. Efforts to increase corn production can be carried out by applying balanced compound fertilizer. The research was conducted at the experimental field of the Faculty of Agriculture, Brawijaya University in Jatikerto, Kepanjen District, Malang Regency. The research design used a randomized block design (RAK) consisting of 7 treatments with 3 replications. Treatments consisted of: 1) P0=control (without fertilization), 2) P1=100% basic fertilizer, 3) P2=urea 400 kg/ha+rock phosphate 150 kg/ha+KCl 75 kg/ha, 4) P3= urea 400 kg/ha+phosphate fertilizer test 150 kg/ha+KCl 75 kg/ha, 5) P4=urea 400 kg/ha+phosphate fertilizer test 200 kg/ha+KCl 75 kg/ha, 6) P5=urea 400 kg/ha+test phosphate fertilizer 250 kg/ha+KCl 75 kg/ha, 7) P6=urea 400 kg/ha+test phosphate fertilizer 300 kg/ha+KCl 75 kg/ha. The data was analyzed by ANOVA and continued with the DMRT test at 5% level. Next, correlation and regression analysis was carried out to see the relationship and influence between parameters. The research results show that the application of phosphate-based inorganic fertilizer can significantly increase plant growth (plant height, number of leaves, stem diameter), corn production (length and diameter of cobs, dry weight of shells), and plant nutrient uptake. The application dose of test phosphate fertilizer (~300 kg/ha) was able to increase plant nutrient uptake and corn production, while the application dose (200-250 kg/ha) of test phosphate fertilizer was the optimal fertilizer dose in increasing total P content and soil available P. The relationship between P uptake and corn production has a positive relationship with a strong level of closeness, which means that high P nutrient uptake can increase corn production.
