Field experiment was conducted in the 2019 and 2020 early cropping seasons at the University of Calabar Teaching and Research Farm, Calabar, to assess the foliage yield of fluted pumpkin (Telfairia occidentalis Hook F.) as affected by organic manure and cutting frequency on soil of Calabar. The experiment was a factorial combination of four poultry manure rates (0, 3, 6 and 9 tonnes per hectare) and three cutting frequency (2, 3 and 4 weekly intervals), laid out in randomized complete block design (RCBD) with three replications. Data were collected on vine length, number of leaves, internode length, fresh leaves, dry matter weights and soil physico-chemical properties, and analyzed. Significant means were compared using Fisher's Least Significant Difference (FLSD) at 5 % probability. Results indicated that the sand proportions decreased after harvest while the silt and clay proportions, the soil pH, total nitrogen, organic carbon, organic matter, potassium, magnesium, effective cation exchange capacity (ECEC) and base saturation all increased after harvest in both cropping years. There were significant (p <.0. 05) effects of PM, cutting frequency and their interactions on vine length, number of leaves, internode length, fresh leaves and leaves dry matter weights in both years of study. Plots treated with 9 t/ha of PM produced the longest vines, higher number of leaves, heavier fresh leaf and leaf dry matter. This was followed by plots treated with 6 t/ha of PM while the lowest was the plot with zero PM treatment. Foliage harvest at 3-weekly cut intervals produced the highest cumulative number of leaves, fresh leaf and leaf dry matter weights, followed by the 4-weekly cut intervals while the lowest was the 2-weekly cut intervals. The interaction of 9 t/ha PM with 3-weekly cut intervals produced the best effect and is therefore recommended. [ABSTRACT FROM AUTHOR] |
