Production of agricultural wastes is increasing while soils are progressively losing organic matter due to intensive cultivation and climatic conditions. This makes the recycling of organic wastes a useful alternative to incineration, landfill or rubbish dumps. The effects of two agro- wastes and mineral fertilizer on growth and yield of leaf amaranth were assessed in a pot experiment at the Teaching and Research Farm, Ekiti State University, Ado-Ekiti. Treatments consisted of poultry manure (PM) and palm oil mill effluent (POME) each applied at 8 and 16MT/ha while NPK 15-15-15 was applied at 150, 200kgha-1 and no fertilizer as control. Seeds of amaranthus caudatus variety were sown in plastic pot (50x20x40cm) containing 20kg top soil. Treatments were arranged in a randomized complete block design replicated three times. Data were taken on plant height, stem girth, number of leaves plant-1, leaf area, root length, fresh weight, dry weight, edible yield and above ground plant weight at 6 weeks after planting. The results revealed that the agrowastes significantly (p<0.05) resulted in better performance of leaf amaranth. Application of 16MT/ha PM gave the highest fresh and edible weight of 211.23 and 98.80g respectively. POME also performed better than NPK fertilizer in some of the parameters measured. This indicated that PM and POME could serves as an alternative sources of nutrient to mineral fertilizer for leaf amaranth and also a sustainable fertility management strategy for crop production.

The growth and production of sweet corn (Zea mays saccharata Sturt) are strongly influenced by good genetics and environmental factors, including how to cultivate the soil so that the availability of nutrients is quite balanced. The long-term goal of this research is to determine the effectiveness of a combination of palm oil mill effluent (LCPKS) and cow dung waste (LKTS) with EM4 bio-activator applied to sweet corn (Zea mays saccharata Sturt). This study used a factorial randomized block design (RBD) consisting of 2 factors with 12 treatment combinations and 3 replications to obtain 36 research plots. The factors studied are the formulation factor of a mixture of palm oil mill effluent with cow dung waste, which is denoted by (A) consisting of A1 = 70% palm oil mill waste and 30% cow dung, A2 = 50% effluent palm oil mill and 50% cow dung waste, A3 = 30% palm oil mill waste and 70% cow dung waste. The dose factor with the symbol (D) consists of, D0 = control, D1 = 1.5 kg per plot, D2 = 3 kg per plot, D3 = 4.5 kg per plot. The parameters observed were plant height (cm), biomass samples (grams), sample production (grams) and plot production (kg). The results showed that different waste mix formulations and administration of different doses did not significantly influence plant height parameters because compost maturity must be assessed by measuring two or more compost parameters to prevent phytotoxicity. Therefore, quality assurance must be carried out on compost to determine the factors that cause phytotoxicity and also research must be intensified in determining lines that will be able to degrade waste faster, more efficiently and also produce non-toxic compost that mixes the soil produced in plant growth. In addition, care must be taken in selecting raw materials for composting. The results showed that the mixed waste formulations significantly affected the biomass of the sample, where the highest average was obtained in processing A3 (30% of palm oil mill waste and 70% of cow dung waste. The research results also showed that dosing had a very significant effect on biomass parameter sample, sample production and plot production where the highest average is in the D3 treatment (4.5 kg per plot).
