Abstract

A pot experiment was conducted at Landmark University Teaching and Research Farm Omu-aran, Kwara to evaluate the of kale to different levels of inorganic fertilizer and bio-activator in derived savanna. The investigated treatment (Kale) was subjected into five levels of NPK fertilizer viz: 0, 5, 10, 15 and 20 kg/m2 and 2 levels of biochar (0 and 200 t/ha). These were assigned randomly into four replicates and fitted into a 5 x 2 factorial experiment in a randomized complete block design. Data collected on the growth parameters, yield and quality attributes were analyzed using ANOVA. Plants were harvested at eight WAP. Number of leaf and plant height were measured weekly. After harvest, root length, fresh and dry weights were also determined. Results showed that treatment 6, biochar 200 t/ha + NPK 0 kg/m2 (200, 0) has the tallest plant height at week 1, 3, 5 and 6 as well as yield parameters in root length, fresh and dry weights. Treatment 6 also gave the highest value amongst the minerals. Treatment 7, biochar 200 t/ha + NPK 5 kg/m2 (200, 5) has the highest number of leaves at week 2, 4, and 6 after planting. Integration biochar 200 t/ha + NPK 10 kg/m2 (200, 10) is recommended for cropping of kale in the guinea savanna zone of Nigeria.
