Assessment of Grain Weight of Maize to Variety, Organic Manure and Inorganic Fertilizer of Asaba Area of Delta State

Abstract

From March 2008 to June 2010, this study was conducted at Delta State University's Asaba Campus' Teaching and Research Farm to assess the response of maize grain weight to variety, organic manure, and inorganic fertilizer. The experiment was reproduced three times in a factional arrangement using a Randomized Complete Block Design (RCBD). Three maize types were seeded at 75cm x 15cm and assessed for grain weight using four different amounts of poultry manure, cow dung, and NPK 20:10:10 fertiliser. The results showed that the hybrid variety that generated 2.1 tha-1 yield in 2008 and 2.3 tha-1 yield in 2009 was better. In 2008 and 2009, the findings of interaction revealed that variety, manure type, and application rates were substantially different (p0.05). Based on the outcomes of the study, it is suggested that I 9022-13, a hybrid maize variety with excellent grain weight, be produced in the research region. Farmers who prefer open-pollinated varieties might cultivate BR9922-DMRSF2 or the Agbor local variety for maize production. (iiFarmers that prefer mineral fertilisers for improved maize crop weight should apply 450 kg NPK 20:10:10 per hectare. (iii) Farmers in the Asaba agro-ecological zone who practise organic agriculture should use 30tha-1 poultry manure to boost maize yields.
