“…Soil fertility depletion through continuous cropping has necessitated measures to maintain or improve soil nutrient status for consistent high crop yield. Most of the approaches to consistency in high crop yields focus on the use of fertilisers, improved cropping systems and the development of genetically improved crop varieties (Díaz-Chuquizuta et al, 2022;Rodríguez-Pérez et al, 2023). In the Southern Guinea Savannah of Nigeria, fertiliser application for crop performance enhancement is necessary in order to improve the living conditions of farmers.…”

Continuous land cultivation has led to the application of fertilisers to maintain high crop yields. Favourable effects of different fertiliser sources for improved crop performance have been reported. However, there is scarce information on crop response to the residual effect of organomineral fertilisers (OMFs) applied to early sole and maize-soya bean intercropping. Consequently, the objective of this study was to evaluate the residual effect of N levels of organomineral and inorganic fertilisers applied to maize and soya bean in sole cropping and intercropping. The study was conducted in the years 2017 and 2018 in the Southern Guinea Savannah, Jalingo, Taraba State, Nigeria. Responses to the residual influence of early season cropping systems and applications of OMF and NPK 20-10-10 were evaluated in repeated field trials. The residual effects of a previously assessed 2 9 factorial arrangement, cropping system (sole and intercrop) and fertiliser applications (0, 50, 100, 150, 200 kg Nha of OMF and 50, 100, 150, 200 kg N ha of NPK fertiliser) were evaluated in a randomised complete block design with three replicates. Maize (ACR-95DT) and soya bean (TGX 1488-2E) were planted at densities of 40,000 and 74,000 plants ha, respectively. Data were analysed using ANOVA at p 0.05. Maize and soya bean plant heights and N uptake significantly increased under the residual influence of sole cropping compared to intercropping in both years. Furthermore, maize-soya bean intercropping produced significantly lower grain yields than their sole crops in both years. The land equivalent ratio of the system was greater than one in both years. The residual effect of early season intercropping reduced subsequent yields of maize and soya bean, while OMF residual effects favoured sole maize, sole bean, and maize-bean intercrop performances at 100 kg Nha.
