    Utilization of Different Crop Residues as Organic Fertilizer
    (Enproct Consultants Limited, 2012-04-17) Olowoake, A.A. and Adeoye, G.O.
    Various organic residues are abundant in the most communities and farms in Nigeria. The management of such organic residues poses a serious problem to community hygiene. Surplus farm waste can be recycled into useful product for meeting the nutrient requirement of crops. Poultry manure, Mucuna husk, Gliricidia leaves and Rice straw were collected and composted to produce organic fertilizer. The estimation of time of maturity of five different compost types; Poultry manure + Mucuna husk (PmMh), Poultry manure + Leaf litter (PmLl), Poultry manure + Rice straw (PmRs), Poultry manure + Leaf litter + Rice straw (PmLlRs) and Poultry manure + Leaf litter + Mucuna husk (PmLlMh) was investigated as well as the effects of the compost on yield of maize in the field. The experimental design was randomized complete block design with three replications. Composting of organic residues of high and low carbon–nitrogen ratios together reduce the composting cycle to 49 days. Significant differences (P< 0.05) were found in plant height, stem girth, leaves area, stover dry weight and grain yield with 1.5 t ha-1 PmLlMh. Grain yield value of maize 3.4 t /ha with PmLlMh at 1.5 t/ha were significantly (p< 0.05) higher than that of NPK treatment (3.0 t/ha) after the cropping. Thus, from this study it can be deduced that PmLlMh at 1.5 t ha-1 can serve as an alternative to mineral fertilizer.

    VEGETATIVE PERFORMANCE OF MAIZE (Zea Mays L) ON DEGRADED SOIL AS AFFECTED BY COMPOSTED ORGANIC RESIDUES
    (Published by faculty of Agriculture, Obafemi Awolowo University, Ile-Ife, Nigeria, 2012-08-02) Olowoake, A.A. and Adeoye, G.O.
    The evaluation of five different compost types; Poultry manure + Mucuna husk (PmMh), Poultry manure + Leaf Iittet (PrnLl), Pou1ti-y manure +Rice straw (PmRs), Podt~ -f Leaf litter + Rice straw (PmLlRs) and Poultry manure + Leaf litter + Mucuna husk (PrnLlMh) on the performance of maize under greenhouse conditions was investigated. Maize variety ACR 993 1 -DMRSR treated with 1.5,3.5,4.5 and 6.0 t ha-1 each of the compost treatments was used in first cropping, while NPK 15-15-15 applied at 300,400 and 600 kg ha-1 and control (no fertilizer) were also observed in the second cropping. A completely randomized experimental design with 24 treatments in three replications was conducted. Significant differences (p< 0.05) were found in plant height and dry matter yield of maize. N, P and K uptake of maize from 1.5 t ha- 1 PmLlMh were 20.4, 6.2, 21.9 mg-1 pot respectively and these values were significantly (p< 0.05) higher than that of uptake values obtained from NPK treatment. Residual effect of plant height, dry matter yield and nutrient uptake of maize values obtained from 1.5 ttha PrnLlMh was also significantly (p< 0.05) higher than that of NPK values. It was concluded that PmLlMh at 1.5 t - :,ha-l could serve as effective compost fur maize production.
