RESPON PERTUMBUHAN DAN PRODUKSI TANAMAN JAGUNG MANIS (Zea mays Saccharata Sturt) TERHADAP PEMBERIAN KOMBINASI PUPUK KANDANG SAPI & PUPUK KANDANG KAMBING DAN PUPUK NPK

This study was conducted at the Agricultural Extension Center in Galesong from July to September 2022 to examine the effects of a combination of cow and goat manure, as well as NPK fertilizer, on the growth and yield of sweet corn. The study used a factorial Randomized Block Design (RBD) with two factors: the combination of cow and goat manure (no manure, 5, 7.5, and 11.5 tons/ha) and NPK fertilizer (100, 200, and 300 kg/ha), resulting in 12 treatment combinations with 36 experimental units. Results indicated that a combination of 10 tons/ha cow manure and 15 tons/ha goat manure improved plant height, leaf number, fresh cob weight per plant, and yield per hectare. NPK fertilizer at 300 kg/ha increased plant height, cob length, and fresh cob weight per plot, with no significant interaction between the combination of manures and NPK fertilizer on sweet corn growth and yield.
