Improvement yield of sweet corn (Zea mays Saccharata (Sturt.) bailey using arbuscular mycorrhiza fungi (AMF) and cow manure fertilizer (CMF) on ultisol

This study aims to determine the effectiveness of arbuscular mycorrhiza fungi and cow manure yield sweet corn on Ultisol. research was conducted using a randomized block design (RCBD) in factorial pattern. The first factor is mycorrhizal (AMF) which consists four levels, namely without AMF (A0), 5 g/planting hole (A1), 10 (A2), 15 (A3). second fertilizer (CMF) consisting three CMF (B0), tons ha-1 (B1), (B2). treatment applied consisted 12 combinations were repeated 3 replications, so that there 36 experimental units. observed variables were: weight cob with cob, length, ear diameter, number rows seeds crop production (ton ha-1). results showed highest average husk obtained combination (A2B0) as 289.2 g. productivity (A0B1) 8.52 ha-1.
