ABSTRAK Penggunaan pupuk organik yang dipadukan dengan penggunaan pupuk kimia dapat meningkatkan produktivitas tanaman, dimana unsur mikro yang terdapat dalam pupuk bio-slurry memiliki peran penting dalam proses metabolisme dan proses fisiologis tanaman, serta memperbaiki struktur fisik tanah dan meningkatkan kesuburan tanah. Pupuk kimia menyediakan unsur hara makro yang sangat dibutuhkan tanaman. Penelitian ini bertujuan untuk : (1) Mengetahui kombinasi dosis terbaik antara pupuk bio-slurry padat dan pupuk anorganik terhadap pertumbuhan tanaman jagung manis (Zea mays saccharata Sturt) Varietas Bonanza dan (2) Mengetahui respon antara kombinasi dosis pupuk bio-slurry padat dan pupuk anorganik terhadap pertumbuhan tanaman jagung manis (Zea mays saccharata Sturt) Varietas Bonanza. Penelitian ini dilaksanakan di Bandar Lampung pada bulan Januari 2015 sampai dengan bulan Mei 2015, di atas lahan dengan jenis tanah Ultisol. Rancangan penelitian yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK). Penelitian ini terdiri atas 7 perlakuan yang merupakan kombinasi antara pupuk bio-slurry padat dan pupuk anorganik (pupuk Urea, SP-36 dan KCl), dan masing-masing perlakuan diulang sebanyak 3 kali. Homogenitas ragam diuji dengan menggunakan uji Bartlett dan aditivitas data diuji dengan menggunakan uji Tukey. Jika asumsi terpenuhi, data dianalisis dengan sidik ragam dan dilanjutkan dengan uji Ortogonal Kontras pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa : (1) Kombinasi dosis terbaik antara pupuk bio-slurry padat dan pupuk anorganik terhadap pertumbuhan tanaman jagung manis (Zea mays saccharata Sturt) Varietas Bonanza adalah pupuk anorganik (Urea 250 kg/ha, SP36 100 kg/ha dan KCL 100 kg/ha) dan bio-slurry 2.000 kg/ha (2) Kombinasi dosis pupuk bio-slurry padat dan pupuk anorganik berpengaruh nyata terhadap tinggi tanaman, diameter batang, bobot basah brangkasan, bobot kering brangkasan, laju tumbuh tanaman, indeks luas daun, serta tingkat kehijauan daun tanaman jagung manis (Zea mays saccharata Sturt) Varietas Bonanza. Kata kunci: jagung manis, pertumbuhan, bio-slurry padat , pupuk anorganik. ABSTRACT The use of organic fertilizer in combination with the chemical fertilizers can increase crop productivity, since micro elements contained in organic fertilizers (bio-slurry) has an important role in the metabolism and physiological processes of plants, as well as improve the physical structure of the soil and its fertility. Chemical fertilizers provide macro nutrients that are needed by plants. The aims of the study were to: (1) Determine the best dose combination between solid bio-slurry (manure) and inorganic fertilizer on plant growth of sweet corn (Zea mays saccharata Sturt) Variety Bonanza and (2) Determine the response between dose combination solid bio-slurry and inorganic fertilizers on plant growth of sweet corn (Zea mays saccharata Sturt) Variety Bonanza. This study was conducted in Bandar Lampung from January 2015 to May 2015 on an area with ultisol soil type. The treatments were arranged in a randomized block design (RBD). This study consisted of 7 treatment combinations of solid bio-slurry and inorganic fertilizers (Urea, SP-36 and KCl), and each treatment was repeated 3 times. Homogenity of variance was tested using Bartlett test and additivity of data were tested using Tukey test. If the assumptions were met, the data were analyzed by analysis of variance followed by Orthogonal Contrast test at 5% significance level. The results showed that : (1) The best growth of sweet corn was achieved by the combination of inorganic fertilizer (urea 250 kg / ha, SP36 100 kg / ha and KCL 100 kg / ha) and bio-slurry of 2.000 kg/ha (2) The combination of organic and inorganic fertilizer had significant effect on plant height, stem diameter, wet weight stover, stover dry weight, the rate of plant growth, leaf area index, and leaf greenness of sweet corn (Zea mays saccharata Sturt) Variety Bonanza. Keywords: sweet corn, growth, solid bio-slurry, inorganic fertilizers.
