The Effect of Climate Variability on Maize Production in the Ejura-Sekyedumase Municipality, Ghana

Abstract

Agriculture is one of the sectors most susceptible to changes in climatic conditions. The impact is even stronger in Africa, where rain-fed agriculture is vital for daily subsistence, but where adaptive capacity is low. It is therefore crucial to increase the understanding of the actual climate change dynamics on agricultural productivity. This study examined the effects of changes in climatic variables such as rainfall and temperature on maize production in the Ejura-Sekyedumase Municipality, Ghana. Regression, chi-square and trend analyses were used to establish the relationship between climate variables (rainfall and temperature) and maize yield in the study area. This was supplemented with participatory household interviews with 120 farmers to understand the perception of farmers on rainfall and temperature patterns. The results from the study respondents and trend analysis show that rainfall is shorter in terms of duration and less predictable, whilst temperature has increased. The findings suggest that the general relationship between rainfall, temperature and maize yield is such that maize yield increased with increasing rainfall of the right amount and distribution pattern and decreased with increasing temperature. The study concludes that climate variability and/or change is evident in the study area and its effect on maize yield is severe.

Effects of planting density and variety on productivity of maize-faba bean intercropping system

“…The presence of higher rainfall during 2019 cropping year may have been conducive to achieve improved grain yield. Consistent with this result, Cudjoe et al [ 35 ] reported a positive relationship between annual rainfall and maize yield. The results also revealed that grain yield of maize intercropped with 25% of faba bean density (5.56 t ha −1 ) surpassed the grain yield of maize intercropped with 75% faba bean density by about 18.5% ( Table 1 ).…”

Effects of Rainfall Variability on Maize Production in Afgooye District, Lower Shebelle Region, Somalia

“…This is because the category of people was aware to this statement that rainfall pattern causes poor yield and the maize will failure. This implies that the majority of the respondents were strongly agree with the statement so that This findings are supporting Cudjoe, Antwi-Agyei, and Gyampoh, (2021) [17], provided strong evidence about rainfall pattern and maize production.…”

“…Sample is a further subset of the target population which we would like to include in the study. Thus a sample is a portion, piece, or segment that is representative of a whole [17]. The sample size of the study was 108 farmer.…”

Safety and Efficacy of Novasil Clay (Calcium Montmorillonite) in Children Exposed to Aflatoxin in Ejura-Sekyedumase District in Ghana

“…It is noteworthy that farmers in the Ejura Sekyeduamse District are leading producers of maize, beans and peanuts in Ghana. 20 When cereals are contaminated with aflatoxins, some of the suggested harmful effects on humans are vomiting, diarrhea, hepatitis, cirrhosis, immunosuppression, miscarriages, mutagenic and teratogenic effects, and different cancers. 21 One of the most fundamental approaches to lowering the risk of aflatoxicosis in humans is to avoid eating foods contaminated with aflatoxin.…”
