| 1 | Comparative effects of commercial compost and mineral fertilizer on growth and yield of tomato (Lycopersicon esculentum L) and residual soil chemical properties |
A pot experiment was conducted at the College of Agriculture Screen House, Kwara State University, Malete, Nigeria to study the comparative effects of commercial compost and mineral fertilizer on growth and yield of tomato (Lycopersiconesculentum L) and residual soil chemical properties. The experiment comprised of five treatments namely, Aleshinloye Grade B (un-amended compost), Sunshine Grade B (un-amended compost), Gateway compost (un-amended compost) and mineral fertilizer (NPK 15-15-15 and Urea) each replicated four times and fitted into a Complete Randomized Design (CRD). All treatments were applied at the rate of 100kg N/ha.The research consisted of 2 consecutive experiments in which residual effect was observed in the second experiment. Data on growth and yield parameters collected were plant height, stem girth, number of leaves, number of fruit/plant and weight of fruit/plant. The results showed that the application of Gateway and Aleshinloye composts significantly increased the vegetative growth and yield of the tomato plants than NPK and Urea. Tomato fruit yield values was 116.2 g/ plant with Aleshinloye Grade B and this was significantly (p< 0.05) higher than that of NPK and Urea treatment respectively (45.6 and 48.5 g)after the first cropping. The residual values of tomato fruit yield /plant obtained from the duo of Aleshinloye Grade B and Gateway compost were not different at 5% significant level. Gateway and Aleshinloye grade B composts had a significant effect on soil nutrients after harvesting of tomato when compared with NPK in first and second cropping. This suggests that Gateway and Aleshinloye grade B composts could be used effectively for optimum growth and yield of tomato. | Olowoake, A.A | 73-78. | Proceedings | 2019-11-29 | Organic Agriculture Professionals in Tertiary Institutions in Nigeria. | |
