 ABSTRACT

A field experiment was conducted to study the effect of integrated application of inorganic and organic sources of nutrients onsoil properties and performance of maize (Zea mays L.) incoastal sandy loam soils of Andhra Pradesh. The results showed that the highest drymatter production, grain and stover yield was observed when 125 per cent of recommended dose of fertilizer nitrogen (RDFN) was applied along with 50 per cent of nitrogen through poultry manure (PM). This was followed by the treatments with recommended dose of fertilizer nitrogen (RDFN) alone and its combinations with farmyard manure (FYM) and poultry manure (PM). The physical and physico-chemical properties viz., bulk density, pH, EC and CEC were not significantly influenced by different levels of fertilizer nitrogen along with FYM/ poultry manure. The organic carbon content and urease activity of soils at tasseling and harvest was significantly influenced by the treatments and higher activity was recorded in treatments which received higher levels of nitrogen through fertilizer and FYM/ poultry manure. Significant positive correlation was observed between soil properties and performance of maize.

Key words: Maize, FYM, Poultry manure, Yield, Soil properties, Urease activity.
