Mineral nutrition is a factor that can be easily modified for plant growth and consequently amending soil to alleviate limitation of nutrient availability and/ or absorption in many agricultural practices. Generally, the ammendments provide condusive soil and biological factors necessary for improved plant growth through affecting changes in plant growth and development and particularly chemical compositions. A trial was conducted to evaluate the performance of two varieties of guava supplied with poultry manure and inorganic fertilizers applied alone or in combination for over a period of two years. Two varieties of Guava seedlings Allhabad and White delicious were transported to the field. Cured poultry manure and NPK15:15:15 were used as organic and inorganic manure respectively. Fertilizer Rates were 1kg/stand (0.28ton/ha poultry manure) organic fertilizer +67.5g NPK/stand inorganic fertilizer at four applications per year(F1). Inorganic fertilizer only 135g NPK/stand at four application per year (F2) Organic fertilizer only 2kg/stand(0.56ton/ha) (F3) and control (F0). Result showed that plant when received half organic and half organic fertilizer (0.28t/ha poultry manure+ 67.5n NPK) performed best in terms of growth parameters assessed among the treatments in both white deliciousand Allhabad followed by plants supplied with full organic fertilizer (0.56t/ha poultry manure). However. Allhabad variety had the highest mean value of stem girth and canopy cover while White delicious variety recorded highest mean value in plant height. It was concluded that the use of combined application of poultry manure and NPK fertilizer gave the best performance.
