Abstract: 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.
