Influence of Precursor Crops on Inorganic and Organic Fertilizers Response of Maize at Bako, Western Oromiya, Ethiopia

Tolera Abera, Daba Feyissa, Hasan Yusuf and Tesfaye G. Georgis
The present research was conducted with the objective to determine the right precursor crop with integrated nutrient management is an approach to soil fertility management and play a significant influence on sustainable production of maize (Zea mays). Precursor crops showed significant effect on yield and yield components of maize. Higher grain yield of maize was observed from Niger seed precursor crop. All inorganic and organic nutrients gave better yield of maize on Niger seed precursor crop compared to Mucuna pruriens green manured fields. Maize following Niger seed gave grain yield advantage of 20.19% compared to maize following Mucuna pruriens. The use of Niger seed as precursor crop with 23-46 kg N-P ha-1 and 8 t FYM ha-1 produced better grain yield of maize. Higher grain yield with integrated nutrient management were realized from Niger seed precursor crop. Niger seed precursor crop with integrated nutrients application is the most successful management option for sustainable production of maize. Use of precursor crop and fertilizer enabled maize yield to be maintained at a fairly high level compared to continuous cropping. Thus, it is recommended that Niger seed precursor crop with integrated nutrients are agronomically profitable for sustainable maize production in Alfisols of Bako.
