The Teaching and Research Farm at Delta State University’s Asaba Campus was used to analyse the response of maize grain weight to variety, organic manure, and inorganic fertiliser from March 2008 to June 2010. Using a Randomized Complete Block Design, the experiment was repeated three times in a factional pattern (RCBD). Three distinct maize varieties were seeded at 75cm x 15cm and grain weight was measured using four different amounts of poultry manure, cow dung, and NPK 20:10:10 fertiliser. The hybrid variety that produced 2.1 tha-1 yield in 2008 and 2.3 tha-1 yield in 2009 was found to be superior. The findings of interaction in 2008 and 2009 demonstrated that variety, manure type, and application rates were all significantly different (p0.05). According to the findings of the study, I 9022-13, a hybrid maize variety with excellent grain weight, should be grown in the research region. Farmers who want open-pollinated varieties for maize production should grow BR9922-DMRSF2 or the Agbor local variety. (iiFor enhanced maize crop weight, farmers who prefer mineral fertilisers should apply 450 kg NPK 20:10:10 per hectare. (iii) Farmers who practise organic agriculture in the Asaba agro-ecological zone should use 30tha-1 poultry manure to increase maize yields.
