The present study aims to determine the best organo-mineral fertilization formula for increased production of seed corn at the Faranah/ ISAV. A Randomized Complete Block experimental design comprising variants (D0; D4+50; D6+75; D8+100; D0+150 and D12+0) each repeated three times was carried out. During the vegetative phases the findings revealed that the highest Daily Growth Rates obtained on the 35th Day After Sowing (DAS) with D0 (2.30 cm/day); on the 45th and 55th DAS with D0+150 (2.00 and 4.97cm/day) respectively. At maturity, the tallest plants were obtained with the doses D12+0 (233.00 cm) and D8+100 (232.67 cm) and the shortest plants with D4+50 (192.83 cm). Respective gains of 480kg/ha; 1050kg/ha, 1340kg/ha; 1360 kg/ha and 1880 kg/ha of seed corn yield were obtained with the increase in doses and types of fertilizers used compared to the control. The highest corn seed yields were obtained with the D12+0 and D0+150 inputs, either 4870 and 4350 kg/ha respectively compared to the unfertilized control which obtained 2990 kg/ha. As part of the sustainable improvement in seed corn productivity at ISAV in Faranah, organic manure fertilizer such as cow dung at a dose of 12 000 kg / ha (D12+0) and Triple 17 mineral fertilizer at a dose of 150 kg/ha (D0+150) would be a practice to be popularized.
