  Combined use of crop and animal wastes is necessary in order to obtain adequate amount of organic manure fro use in crop production. Hence field experiments were conducted at two sites in Akure, Southwest Nigeria to compare effect of NPK (15-15) fertilizer (200 kg ha-1) and each of Spent Grain (SG) and ground Cocoa Husk (CH) amended with Cattle Dung (CD), Poultry Manure (PM) and Goat Manure (GM) at equal rates (12.5 :12.5 t ha-1). The effects of treatments on leaf N, P and K concentrations growth and fruit yield of tomato were studied. Compared with control, NPKF and animal manure amended SG and CH increased leaf N and K, plant height, number of branches, leaf area, number and weight of fruits significantly (p>0.05). Fruit yields given by CD, PM and GM amended CH and M and GM amended SG were similar. Among eight treatments compared, CH and SG amended with PM gave height fruit yield, compared with control, NPKF, amended SG and CH increased fruit yield by 268, 342 and 397%, respectively.

  Field trials were conducted in Southwest Nigeria to determine fertilizing effect of pruning of Gliricidia sepium on cowpea (Vigna unguiculata Walps). Pruning of gliricidia was applied at 0, 2, 4, 6, 8 and 10 t ha-1 as mulch. Soil fertility status and nutrient status and yield of cowpea given by the treatments were evaluated. Soil organic matter, N, P, K, Ca Mg and leaf N, P, K, Ca Mg and pod and grain yield of cowpea increased with amount of pruning. Relative to control 2, 4, 6, 8 and 10 t ha-1 pruning increased seed weight by 23, 97, 165, 201 and 218%, respectively.

  In order to investigate the effect of goat dung manure on okra, field experiments were carried out at Ado-Ekiti and Akure in Southwest, Nigeria. In a preliminary study carried out at Ado-Ekiti the effects of 0, 2, 4, 6 and 8 t ha-1 goat manure (GM) on okra (var. v35) were studied. Goat manure applied at 4, 6 and 8 t ha-1 increased number of pods by 25, 31 and 44%, respectively. At Akure the relative effects of 160 kg ha-1 urea (72 kg ha-1 N), 8 t ha-1 GM, 6 t ha-1 GM+40 kg ha-1 urea (U), 4 t ha-1 GM +80 kg ha-1 U, 22 t ha-1 GM + 120 kg ha-1 U and no treatment on soil chemical composition and growth and yield of okra (var. NHAE-47-4) were studied. The 8 t ha-1 GM was more effective than 160 kg ha-1 U in increasing number and weight of pods. Addition of GM to urea increased pod weight, Soil Organic Matter (SOM), N and pH. GM increased soil, N, P, K and mg contents. The 2 t ha-1 GM+120 kg ha-1 gave the highest okra yield.

  This study investigated effect of goat manure treatments and NPK fertilizer on soil nutrient, content leaf nutrient, content growth and yield components of pepper (Capsicum annum) grown at Akure soil in the rainforest zone of Nigeria. The treatments applied to soil and replicated three times were 0. 2.5, 5.0, 7.5, 10.0 t ha-1 goat manure and 250 kg ha-1 NPK 15-15-15 fertilizer. The trial was conducted twice. Chemical analysis of goat manure used was done in addition to initial soil analysis. The soil was slightly acidic and marginal in organic matter (OM) and available P. The goat manure was relatively high in organic matter, N and P compared with K, Ca and Mg. Goat manure treatments increased soil …. N, P, K, Ca, Mg and pH and leaf N, P, K, Ca and Mg of pepper. Growth and yield parameters such as number of leaves and branches, plant height, stem girth, number and weight of fruits were significantly (p>0.05) increased by goat manure treatments. However NPK fertilizer increased soil N, P and K status leaf N status and growth and yield parameters compared with manure treatments. Relative to control, 2.5, 5.0, 7.5 and 10.0 t ha-1 goat manure and NPK fertilizer increased number of fruits by 36, 82, 108, 141 and 195%, respectively. The increases in fruit weight were 6, 18, 39, 65 and 111%. The 10.0 t ha-1 manure is recommended.

  Screen house experiment was conducted to study effectiveness of Cocoa Pod Husk Ash (CPHA) as source of nutrients for kola (Cola nitida) seedlings. Six levels of CPHA namely: 0. 2, 4, 6, 8 and 10, t ha-1 and 200 kg ha-1 NPK (15-15-15) fertilizer (NPKF) were applied to seedling at Akure and Ibadan Southwest Nigeria. The CPHA treatments and NPKF increased significantly the seedling height and number of leaves. The 2, 4 and 6 t ha-1 CPHA had higher values of the growth parameters than NPKF. Application of CPHA increased soil organic matter, available P and exchangeable K, Ca and Mg. Compared with NPKF, application of CPHA increased significantly root N, P, K, Ca and Mg concentrations which increased with level of CPHA. Compared with NPKF, CPHA at 2, 4, 6, 8 and 10 t ha-1 gave higher values of root P and Ca uptake. The 4 and 6 t ha-1 CPHA gave highest values of seedlings height and number of leaves respectively and higher root Ca uptake.
