Abstract. Sweet corn production in Indonesia can be increased by intensification program, such as the use of superior cultivars, the use of balanced fertilizer, and the use of organic fertilizer. Objective of the research was to study Integrated Crop Management System, that related to use of fermented organic fertilizer (bokashi) which suitable to sweet corn crop, especially in lowland area of Karawang district. The method of research was experiment. The experimental design was Randomized Block Design, that consisted of 16 treatments and 3 replications. The treatments were 4 bokashi dosage (0, 5, 10 and 15 ton ha-1) combined with 4 varieties of F1 sweet corn (Bonanza, Talenta , Secada and Sweet Boy). The data were analyzed using analysis of variance and Duncan multiple-range test at 5%. The results show that bokashi dosage had given difference on plant height, number of leaves per plant, diameter of the stem, weight of ears, number of grain rows, and yield. Dosages of 10 tons ha-1 bokashi gave the best growth and sweet corn yield of Sweet Boy F1 varieties on Integrated Crop Management System. Keywords: Sweet Corn, Bokashi, CMS. Sari. Produksi jagung manis di Indonesia dapat ditingkatkan dengan program intensifikasi, diantaranya dengan penggunaan kultivar unggul, pupuk berimbang, dan pupuk organik. Tujuan penelitian ini adalah untuk mempelajari sistem pengelolaan tanaman terpadu, yang berhubungan dengan penggunaan pupuk orga-nik bokashi yang cocok pada tanaman jagung manis, khususnya di dataran rendah Karawang. Metode penelitian ini menggunakan percobaan. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok, terdiri dari 16 perlakuan dan 3 ulangan. Perlakuan terdiri dari 4 dosis bokashi (0, 5, 10 dan 15 ton ha-1)  yang dikombinasikan dengan 4 varietas jagung manis F1(Bonanza, Talenta , Secada dan Sweet Boy). Data dianalisis menggunakan analisis varians dan uji jarak berganda Duncan pada taraf 5%. Hasil menunjukkan perlakuan dosis bokashi memberikan perbedaan pada tinggi tanaman, jumlah daun, diameter batang, berat tongkol, jumlah baris biji, dan hasil. Dosis bokashi 10 ton ha-1 memberikan pertumbuhan dan hasil terbaik jagung manis varietas Sweet Boy pada sistem Pengelolaan Tanaman Terpadu. Kata kunci: Jagung Manis, Bokashi, Pengelolaan Tanaman Terpadu

Calcium-magnesium silicates improve the soil physicochemical properties and provide benefits to plant nutrition, since they are sources of silica, calcium and magnesium. The objective of this study was to evaluate the grain yield of irrigated corn fertilized with calcium-magnesium silicate. The experiment was carried out in a greenhouse in Campina Grande - PB, Brazil, using plastic pots containing 80 kg of soil. The treatments consisted of the combination of four irrigation depths, related to water replacement of 50, 75, 100 and 125% of the crop evapotranspiration, with fertilizer levels of 0, 82, 164 and 246 g of calcium-magnesium silicate, with three replications. The experimental design was in randomized blocks, with the irrigation depths distributed in bands while the silicon levels constituted the subplots. Corn yield was influenced by calcium-magnesium silicate and by irrigation depth, obtaining the greatest grain yield with the dose of 164 g pot-1 irrigated at the highest water level. The water-use efficiency of in corn production tended to decrease when the irrigation depth was increased. The best water-use efficiency was observed when the irrigation level was between 87 and 174 mm, and the dose of silicate was 164 g pot-1.

Jilin Provincial Academy of Agricultural Machinery initiated studies in 2000 to develop the methodology for successful application of subsurface drip irrigation (SDI) for corn production on the deep silt loam soils of the northeast plains, China. Irrigation water use for corn can be reduced by 37–52% when using SDI compared with more traditional forms of irrigation in the region. Irrigation frequency has not been a critical issue when SDI is used for corn production on the deep silt loam soils of the region. A dripline spacing of 1.5 m has been found to be most economical for corn grown in 0.76 m spaced rows. Nitrogen fertigation was a very effective management tool with SDI, helping to maximize corn grain yield, while obtaining high efficiencies of nitrogen and water use. The research SDI systems have been utilized since 2000 without replacement or major degradation. SDI systems lasting 10–20 years are cost competitive for corn production with the more traditional forms of irrigation in the northeast plains for certain field sizes.
