ABSTRACT
Pot experiment was conducted to test the response of tomato (Lycopersicon esculentum Mill) to different levels of “Power-Plant” liquid organic fertilizer in Delta State University, Asaba Campus at early and late planting periods. Six levels of the fertilizer were applied at each planting (0, 10, 20, 30, 40 and 50 l/ha). Fifteen kilogram of processed soil was weighed into each of the experimental bags. The soil was taken from Department of Agronomy Experimental Farm. Local tomato variety used was obtained from Ogbe-Ogonogo market in Asaba. The seeds were sown in nursing bed for two weeks after germination before transplanting. The experimental bags were arranged in a completely randomized design with four replications. Data collected on growth and yield parameters were: plant height, number of leaves, leaf area, number of branches, number of fruits and fruits weight per pot. Data were analyzed following the ANOVA technique and mean differences were adjudged with least significant differences (LSD) at P<0.05. The results obtained showed that the growth and yield of tomato increased with increase of the liquid organic fertilizer application and the 50 l/ha was superior to lower levels in the growth and yield data measured at both early and late planting. Also, soil chemical properties were improved after harvest. Therefore, the use of the liquid organic fertilizer could afford tomato growers with a suitable nutrient source for improving the production of the vegetable for both their homes and market, and providing fresh tomato all year round. |
