Background: The benefits of organic manure in sustainable agriculture cannot be overemphasized in view of the balanced supply of nutrients. Arachis hypogea is a lipid producing food nutrient supplement that provides more than 30 essential nutrients and phytonutrients. This study was carried out to assess the potency of decomposed fluted pumpkin pods as organic manure in soil cultivated with the test crop.
Methods: Soil samples (0-15cm depth) collected from the study site, CRUTECH, Calabar, Cross River State, were analysed using standard methods for physico-chemical properties. Pods of fluted pumpkin were macerated into small pieces, weighed and mixed with 2.0kg of sandy loam soil. These were allowed to condition for 3 weeks. The levels of 0.5, 1.0, 1.5 and 2.0kg of fluted pumpkin pods were used alongside a control (0kg-Soil only) treatment. Each treatment containing 2.0 kg sandy loam soil + appropriate level of fluted pumpkin pods was placed in poly bags and four (4) seeds of A. hypogea were sown directly in each poly bag.
Results: The contents of available phosphorus, calcium, organic carbon, total nitrogen, sodium, magnesium and potassium significantly (P < 0.05) increased with increase in the level of decomposed fluted pumpkin pods. In addition, the values recorded in all soils treated with decomposed fluted pumpkin pods were significantly (P < 0.05) higher than that of the control treatment (0kg).
Conclusion: Decomposed fluted pumpkin pods has the potentials as a valuable source of organic manure for improvement of growth performance of A. hypogea.
