Comparative Performances of Organic and Inorganic Sweet Corn Grown on Coastal Land

Coastal land serves as an alternative growing area for organic sweet corn production. Establishing an organic growing environment requires at least two years for short growing crop like sweet corn. This experiment aimed to evaluate the first year growth and yield performances of organic and conventional sweet corn production systems on coastal land. Experiment was conducted on entisol of coastal land from August to November 2019 at the City of Bengkulu and was arranged in a randomized complete block design with three replicates. Treatments were (1) organic production systems and (2) inorganic production systems. Sweet corn performances were observed in terms of plant weight, leaf number, leaf length, leaf greenness, shoot fresh weight, root fresh weight, root dry weight, level of sweetness, fresh weight of husked ear and fresh weight of unhusked ear. Results indicated that during the first year of organic production system for sweet corn, sweet corn grown in organic production system had similar plant weight, leaf number, leaf length, leaf greenness, shoot fresh weight, root fresh weight and root dry weight of sweet corn grown in inorganic production systems, except shoot dry weight. In addition, yield of organic sweet corn, as indicated by fresh weight of husked ear and fresh weight of unhusked ear, were 29 % and 23 %, respectively, lower than sweet corn grown in inorganic production system.
