Organic White Corn (Zea mays L. IPB var. 6) Production through the Integration of Bio-fertilizer on Chicken Manure

บทคัดย่อ

White corn is the most important substitute staple in periods of rice shortage. Currently, there is an increasing global trend toward reducing dependence on synthetic fertilizers. ​The increasing demand for organic produce among health-conscious consumers is driving the adoption of sustainable agricultural practices, including the use of organic fertilizers and bio-fertilizers to meet plant nutrient needs. A field experiment was conducted to evaluate the effectiveness of bio-fertilizer added to chicken manure in terms of growth, yield, and physicochemical characteristics of corn. The study used a Randomized Complete Block Design (RCBD) consisting of five treatments with three replications each, and data were collected on the growth, yield, and physicochemical parameters of corn. Data were analyzed using Analysis of Variance (ANOVA) in RCBD, and Comparisons among means were performed using Duncan Multiple Range Test (DMRT) to determine the specific significant differences among treatments. One-half the recommended rate of Azospirillum combined with half the recommended rate of Mykovam® at half the amount of chicken manure was comparable to using the full-recommended inorganic fertilizer in terms of plant height, days to silking, ear height, and average length of ears. Moreover, the same treatment combination significantly affected all growth and yield parameters, except for plant stand and average number of ears, which were comparable to using the full-recommended rate of chicken manure. The overall results of this study suggest that combining bio-fertilizer with organic amendments, like chicken manure, using only half the recommended rate, can effectively enhance corn production.
