Abstract

The objective of this research was to compare the effect agricultural waste and Community waste on Purple Waxy Corn (Khow Niaw Fancy Muang 111) production. The experiment was laid out in Randomized Complete Block Design (RCBD) with 3 replications. Each replication consisted of 50 plants on 3 x 3 m² bed. There were 5 treatments such as T1: application of 15 – 15 – 15 and 46 – 0 – 0 chemical fertilizer formular at 50 kg/rai each; T2: application of chicken manure at 600 kg/rai; T3: application of Bogachi at 200 kg/rai; T4:  application of corn cob compost at 250 kg/rai; T5: application of Maejo compost at 3000 kg/rai. At the earlier growth stage, T1 was most appropriate. This treatment resulted in 96.39 cm plant height and yield of 3635.56 kg/rai. The treatment also tended to result in 50% flowering date and harvesting date at 44.67 and 70.67 days, respectively. T1 also tended to result in the highest number of complete ear, average plant dry weight, and fresh weight of ear with husk at 1.38 ears/plant, 234.67 g/plant and 308.67 g/ear, respectively. However, if better quality after flowering is needed then T2 is more appropriate. This due to the highest results in fresh weight of ear without husk yield and grade A yield at 2241.81 kg/rai and 32.67%, respectively.
