Abstract

The time of basal fertilizer application in maize production influences the economic and biological yield of the maize crop in the sub-Saharan region and Ghana in particular. Therefore, inappropriate timing of basal fertilizer application in maize production is one of the major factors that reduces maize yield. Field experiments were conducted at the Tamale Technical University experimental field during the 2024 and 2025 cropping seasons from August to November each year to evaluate the effect of time of basal fertilizer application on the growth and yield of maize. The experiment was arranged in a Randomized Complete Block Design with three treatments and three replications. Data were collected on growth and yield parameters. The data were analyzed using analysis of variance, and treatment means were compared using the least significant difference test at a 5 % probability level. The results showed that timing of basal fertilizer application had a significant (p < 0.05) effect on the growth and yield parameters of maize. Maize plants that received basal fertilizer treatment at 4 WAP recorded the highest vegetative growth attributes while maize plants that received basal fertilizer treatment at 2 WAP produced the highest yield and yield components. The study concludes that the application of basal fertilizer at 2 WAP results in higher grain yield and yield components. It is therefore recommended that farmers apply basal fertilizer at 2 WAP to achieve optimum maize growth and grain yield.

Abstract

Agricultural production and food security among smallholder farmers has been threatened as a results of the effect of the changing climate. This study sought to analyse the changing climate and its impact on livelihoods among smallholder rural farmers in the Karaga district of Ghana. The research adopted a mixed-method approach where both quantitative and qualitative data were used. Primary data was obtained from 272 households through interviews, focus group discussions, field observation, and key informant interviews. The findings show that majority of farmers recognize the negative effects of climate change on their livelihoods. Farmers also perceive potential benefits from new technologies such as high-yielding varieties and irrigation that can enhance their well-being. Smallholders also confirmed that the adaptation and mitigation strategies were through indigenous weather forecasting, and bio-insecticides innovations. In the years of crop failure because of climate hazards, smallholder farmers resort to trading, firewood harvesting for sale and charcoal burning as a coping livelihood strategy. The research also reveals that there is no significant differences between gender and adaptation response to the changing climate. The study further reveals that women and children are the most vulnerable during climate-related displacements. In conclusion, the ancient traditional practices of smallholder farmers, such as the use of ‘rain callers’, the use of forest reserves as shrines, indigenous weather forecasting, and the use of bio-insecticide innovation, are still very relevant in adapting to climate variability. The research recommends the promotion of indigenous weather information systems and sustainable agricultural practices to build rural smallholders' capacity to adapt.
