“…This is significantly higher than average fertilizer used by rainforest (153.56 kg/ha) and montane savanna (125.75 kg/ha) respectively. The yearly average of the sample was about 272.6 kg/ha which is lower than the recommended usage of 400 kg/ha application level for effective optimum growth and yield of maize (Law-Ogbomo, 2009). The result also shows that maize farmers in the guinea savanna used an average 12.6litres/ha of pesticides which is significantly higher than average pesticides used by montane savanna (2.98 lt/ha) and rainforest (2.87 lt/ha) respectively.…”

Increasing threat of climate change is aggravating the problem of declining agricultural productivity in the face of rapid population growth. This implies that rural sustainance and food security is under threat and stress. Given that crops differ in climate requirements and economic importance, analysis of the attendant effect of climate change on specific crop remains to be adequately explored. This study uses Ricardian approach to examine the effects of climate change on maize production in Nigeria.Multistage sampling technique was employed for the study. Data were collected on 346 maize-based farming households in three different agro-ecological zones of Nigeria.Average age of the farmers and household size were 45years and 8 persons respectively. Average years of farming experience and years of schooling were 25.6 and 6.5 years respectively. The empirical results showed that maize net revenue is sensitive to climate change. Seasonal marginal impact analysis showed that increase in rainfall during rainy season increased Maize Net Revenue (MNR) in rainforest, guinea and montane savanna respectively. Marginal increase in rainfall during the dry season increased MNR in rainforest while it decreased MNR in guinea and montane savanna respectively. However, marginal increase in temperature during dry season has positive impacts on MNR in all AEZs. The predicted results using a range of climate scenarios confirm that climate change will have negative impact on maize net revenue in the future. Maize Farmers have taken adaptive measures against climate change which are changing the planting dates, changed land-use practices, mixed cropping and mixed farming. The major barriers to adaptation are inadequate credit or saving and inadequate knowledge of appropriate adaptation strategies suited for the local climate conditions.

Two factorial pot experiments arranged in a Completely Randomised Design (CRD) with three replications were carried out to assess the impact of different levels of soil compaction and fertilizer amendments on root growth and biomass yield of maize (Zea mays L.) and soybean (Glycine max L.) plants. The treatments were different rates of bulk densities – 1.3, 1.5 and 1.7 Mg m-3 and fertilizer amendments comprising 100% poultry manure (applied at 15 g/plant), 100% 15:15:15 NPK fertilizer (applied at 2.89 g/plant) and 50% rate each of poultry manure and NPK fertilizer (applied at 7.5 g poultry manure + 1.45 g NPK/plant), and control (no fertilizer amendments). Soil compaction reduced the heights of maize and soybean plants. Increasing soil compaction resulted in the accumulation of most of the root biomass in the uncompacted soil above the compacted layer. Application of soil amendments increased the relative root biomass of maize plants in the uncompacted soil, while that in the compacted soil was reduced. In the case of soybean plants, although the relative root biomass in the uncompacted soil was relatively greater than that of maize plants, application of soil amendments tended to slightly decrease the relative root biomass to that of the control. The shoot biomass of both crops decreased with increasing soil bulk density. All the applied soil amendments significantly increased the shoot biomass of maize and soybean plants over the control. The magnitude of response of the crops to the soil amendments was greater in soybean than in maize plants. Soil compaction and amendments significantly influenced root/shoot ratio of both crops. The root/shoot ratio decreased with increasing compaction from 1.3 to 1.5 Mg m-3, however, at 1.7 Mg m-3, the root/shoot ratio increased. The fertilizer amendments significantly influenced the root/shoot ratio of maize but not soybean plants. The fertilizer amendments increased the biomass of both roots and shoots, being higher in the former than in the latter. The fertilizer amendments x compaction interactions showed that the root/shoot ratio was influenced by the type of crop, and the confounding effects of factor interactions on the relative increases/decreases in shoot and root growth. Overall, soil compaction accounted for 52 to 100% of the variations in the magnitude of the measured parameters of maize plants, and 62 to 98% for soybean plants. The ideal bulk density for shoot biomass production of both crops should, therefore, be within the range of 1.3 – 1.5 Mg m-3. At soil bulk density of 1.5 Mg m-3 and above, soil amendment should be added to ameliorate the negative impact of soil compaction.

“…This observation is in line with [26] who reported that nutrient from mineral fertilizers enhance the establishment of crops prior to their influence on soil properties. Although maize is a short term crop, it has a strong nutrient exhaustive effect in soils [27]. This incidence might have resulted in the low chemical properties of the soil among experimental plots despite their recommended and higher application rate.…”

Soil impoverishment remains a major constraint to food crop production in the Guinea Savanna agroecology of Ghana. Most soils identified in this ecology are fragile and deficient in nutrients due to inappropriate management practices. To resolve this challenge, field studies were conducted to assess the polycultural productivity of maize as affected by tillage practices, fertilizer rates and intercropping systems. The study was however conducted in two cropping seasons (2016 and 2017) at Yagaba in the Mamprugu Moaduri District of Northern Ghana. Treatments consisting of 2 tillage practices (direct seeding and ploughing), 2 fertilizer application rates (zero rate [0-0-0 kg/ha NPK] and recommended rate [60-30-30 kg/ha NPK]) and 3 intercropping systems (sole maize, cowpea [Vigna unguiculata L. Walp] and soybean [Glycine max L.]) were factorially examined in three replications using randomized complete block design. Although the maize responded differently to the varied treatments, its exposure to ploughing, 60-30-30 kg/ha fertilizer rate and soybean intercropping system were in general influential in enhancing vegetative growth, yield and yield components. The responsiveness of maize to ploughing and 60-30-30 kg/ha fertilizer rate increased grain yield by 8.60% and 37.68%, respectively than their untreated controls. Regardless of not directly supplying the intercrops with the inorganic fertilizer, nodulation count and effectiveness of cowpea and soybean were improved under ploughed fields treated with 60-30-30 kg/ha fertilizer rate. The combined impact of ploughing, 60-30-30 kg/ha fertilizer rate and soybean integration resulted in higher profit returns. Hence, this study recommends to small-holder farmers in the Guinea Savannah agroecology of Ghana to adapt to the implementation of ploughing, 60-30-30 kg/ha fertilizer rate and soybean intercropping system for yield improvement and profit maximization.
