ABSTRACT Waterleaf (Talinum fruticosum) is an important crop eaten as a leafy vegetable by many people in West Africa. Research has explored various rates of poultry manure (PM) application administered in single doses to waterleaf, but little is known about how waterleaf responds to split regimes of PM; particularly when its foliage/stem is harvested in-season. The objective of this study was to determine how different split regimes of PM paralleled with in-season harvesting affects the fresh weight (FW) and growth of waterleaf. The experiment was laid out as a randomized complete block design with 4 treatments and 6 replications. Treatments included: one single application (T1), 4 split regimes of ratio 25:25:25:25 (T2), 2 split regimes of ratio 50:50 (T3), and a control (0 t/ha) manure application (T0). There was no effect of PM application on growth parameters: leaf no/plant, plant height and branch number. However, PM applied in split regimes significantly affected fresh weight yield at different harvest times. At the first harvest FW reached 6.83 t/ha but this declined in subsequent harvest. Plants which received manure application produced more FW (about 1 ton/ha more) than the control at the 3rd and 6th week after planting (WAP). In the 9th WAP, T2 produced the highest FW of 2.4 t/ha while in the 12th WAP, T2 and T3 outperformed other treatments (1.87 and 1.83 t/ha). This study showed that PM application in 4 split doses of 25:25:25:25 followed by 2 split doses of 50:50 has potential to increase FW yield at intermittent harvest during the season. |
