Effect of Application of Palm Bunch Ash on the Growth and Yield of Eggplant (Solanum melongena L.) in a Pineapple Orchard

The experiment was conducted at Akwa Ibom State University Teaching and Research Farm Obio Akpa Campus during the 2020 first planting season to evaluate the effect of application of palm bunch ash on the growth and yield of eggplant (Solanum melongena L.) in an established pineapple orchard. The experiment was laid out in a randomized complete block design and replicated three times. The treatments were five (5) different rates of Oil palm bunch ash - 1.0ton/ha, 2.0tons/ha, 3.0tons/ha, 4.0tons/ha and a control (0ton/ha - no fertilizer). Data collected for the growth and yield parameters were subjected to analysis of variance. Significant means were compared with least significant differences (P<0.05) at 5% probability level. Result showed significant differences (P<0.005) in all the growth parameters (plant height, number of leaves, stem girth, leaf area) and yield parameters (number of fruits/ plant, length of fruits/plant, circumference of fruits/plant, yield of fruits/plant). Treatment with 4.0tons/ha palm bunch ash produced higher values of plant at 2, 4 6, 8 weeks after planting, while the lowest values of plant height was recorded with 1.0ton/ha treatment at 2, 4, 6, 8 weeks after planting compared to the control treatment. The treatment with 4.0tons/ha oil palm bunch ash also had significantly values of number of leaves, stem girth and leaf area at 2, 4, 6, 8 weeks after planting. The least values of stem girth and leaf area at 2, 4, 6, 8 weeks after planting were recorded with 1.0ton/ha treatment. Higher values of number of fruits/plant (17.30), length of fruits/plant (12.50cm), circumference of fruits/plant (15.75cm) and fruit yield (20.13t/ha) were obtained with 4.0tons/ha oil palm bunch ash treatment while least values of number of fruits/plant (4.77), length of fruits/plant (10.43cm), circumference of fruits/plant (13.11cm) and fruit yield (5.42t/ha) were recorded with 1.0t/ha compared with the control treatment.
