摘要

Pot and field experiments were conducted to determine the effects of inorganic fertilizer, organic manure and combination of both on growth, calyx yield and quality of roselle. Treatments included: control no fertilizer (T1), 300 kg/ha NPK 20-10-10 (T2), 2.5 t/ha (T3), 5.0 t/ha (T4), 7.5 t/ha (T5), 10 t/ha cassava peel compost (CPC) (T6), 2.5 t/ha CPC+150 kg/ha NPK (T7), 5.0 t/ha CPC+150 kg/ha NPK (T8), 7.5 t/ha CPC+150 kg/ha NPK (T9) and 10 t/ha CPC+150 kg/ha NPK (T10). Application of mineral NPK in combination with CPC resulted in the highest calyx yield (22.2 t/ha). Integrated use of 5.0 t/ha CPC+150 kg /ha NPK yielded 22.2 t/ha calyx which was 45% higher than yield obtained from 300 kg/ha mineral NPK. Combination of compost with NPK also increased the concentrations of essential proximate and nutritional quality of roselle calyx. This study indicated that combination of crop waste compost together with mineral fertilizer proved more efficient than either organic or inorganic fertilizer used alone in increasing yield and quality of calyx. Economic analysis favoured the use of 150 kg/ha NPK with 5.0 t/ha CPC. Therefore, this combination seemed to be optimum for good growth and high quality roselle production in the southern guinea savanna of Nigeria.
