Effects of Mineral Fertilizer and Different Sources of Organic Manure Combination on the Growth and Grain Yield of Maize in Sudano-Sahelian Savanna, Nigeria
- Jacob M. WAPA
- Field trials were carried out in 2008 and 2009 cropping seasons at the Teaching and Research Farm of the Department of Soil Science, University of Maiduguri, Maiduguri (11o 53’ N; 13o 16’ E). The objective of the study was to ascertain the effects of the mineral fertilizer in combination with the three different organic manure sources on the growth and yield of Maize in the study area. The treatments consisted of four levels of nitrogen fertilizers (0, 45, 60 and 90 kg N/ha) combined with three types of organic manures (cow dung, municipal wastes and poultry droppings) applied at three rates of each organic manure (0.0, 2.5, and 5.0 tons/ha). The experiment therefore contained twenty-eight (28) treatments laid out in factorial design and replicated three times in a randomized fashion. Soil texture (particle size analysis), soil pH, electrical conductivity (EC), effective cation exchange capacity (ECEC), percentage base saturation (PBS), soil organic carbon (SOC), total N, C:N ratio, available P (Bray-1), and exchangeable K. An extra-early variety of maize (SAMMAZ 28) was obtained from the Promoting Sustainable Agriculture in Borno State (PROSAB), Maiduguri. Plant height, number of leaves per plant, and leaf area were some of the growths parameters measured as well as grain yield in kg/ha. Plant height was not so much affected by the combination of nitrogen fertilizer and organic manure but nitrogen levels alone significantly affected the plant height in 2008, 2009 and in the combined analysis. Leaf area was also significantly affected by nitrogen levels in 2008, 2009 and in the combined analysis. Leaf area was also significantly affected by organic manure types in 2009 and in the combined analysis but not in 2008. Combining rates of nitrogen fertilizer (90 kg/ha N) with poultry droppings (5.0 tons/ha) gave the highest grain yield especially in 2008 (2466.7 kg/ha) and in the combined analysis (1883.7 kg/ha). It could deduce that grain yield and yield parameters were significantly increased with the application nitrogen fertilizer (90 kg N/ha) in combination with cow dung and poultry droppings at the rate of 5.0 tons/ha. Nitrogen fertilizer rate of 60 or 90 kg/ha in combination with poultry manure or cow dung (5.0tons/ha) will give optimum yield of maize on the savanna soils.
