    Integrated agro-aquaculture: the role of water from fish ponds on growth performance of cenchrus ciliaris
    (Rangeland Society of Tanzania (RST), 2022) Guranywa, V.T.; Lamtane, H.A; Selemani, I
    This study assesses the contribution of water from fish ponds on growth performance of African fox grass, Cenchrus ciliaris. Twelve plots each with a dimension of 2 m by 6 m were prepared and planted with African fox grass. Six plots received water from fish ponds (Treatment one) and another six plots were irrigated using stream water (Treatment two). The distance between one plot and another was 50 centimeters while the distance between the two treatments was 3 m apart and each plot was sown with 40 cuttings of Cenchrus ciliaris. Each plot received 40 liters of water during morning and evening hours (7:00 am and 6:00 pm). The experiment lasted for 72 days when all plots were harvested. Soil samples were collected from each plot and taken to soil laboratory for further analysis. The following parameters were determined: total Nitrogen, Phosphorus and Organic Carbon. During harvesting the wet weight for above ground biomass was measured using spring balance. The nutritive values of the pasture samples were determined using the Standard Analytical Procedure. Results showed that there were slightly higher total Nitrogen and Organic Carbon from plots received water from fish ponds. However, there was no significant difference (P>0.05) in all parameters measured between the two treatments. Although there were no significant differences between the treatments, water effluents from fish ponds can be utilized for irrigating pasture as one way or recycling nutrients. It is recommended that further study should be conducted during the dry season because the present study coincided with the onset of rainy season.
