Abstract
A field experiment was conducted to study the effects of different rates of farm yard manure (FYM), poultry manure (PM), sewage sludge (SS) and chemical fertilisers an grain yield and NPK uptake of maize plants. The chemical fertilisers and different organic manures were incorporated in soil individually and in combination, before sawing the maize crop variety Agaiti 85. The experiment was carried out under Randomised Complete Block Design (RCBD) with 3 repeats. The results revealed that
PM significantly enhanced grain yield y maize when applied alone or in combination with half of ecommended chemical fertilizer as compared to FYM, SS and NP fertilisers. However, organic manures (FYM, SS) performed significantly well when applied in combination with chemical fertilisers. The maximum increase in NP uptake was obsewed with the application of chemical fertilizer (NP) d 90- 60 kg ha!’ and K uptake with PM alone.
