“…Several studies in Ghana showed that maize yield response increases with N application [17,[47][48][49][50]. Others have also shown that the addition of fertilizer N increases maize radiation interception and radiation use efficiency, and thereby biomass and yield [51][52][53]. Contrary to expectations, our study shows there was large variation in the response of grain yield to additional N fertilization.…”

“…The yield of maize with the application of <30 kg N ha −1 was equivalent or higher than that of maize grown >60 kg N ha −1 . Muchow and Davis [52] indicated that the efficiency of N's utilization by maize (defined as grain yield per unit N uptake) varies under different climatic, soil, and management conditions. It also demonstrated that radiation use efficiency at higher rates of N declines during grain filling and supplying N under water-limited growth decreases nitrogen use efficiency.…”

Monitoring and Modelling Analysis of Maize (Zea mays L.) Yield Gap in Smallholder Farming in Ghana

Modelling and multiple linear regression were used to explore the reason for low maize yield in the Atebubu-Amantin and West Mamprusi Districts of Ghana, West Africa. The study evaluated maize yields on twenty farms against measures of soil fertility, agronomic attributes and soil water availability. Correlations between yield, soil fertility, rain, crop density, and weed biomass, were low, and no single factor could explain the low yields. A 50-year virtual experiment was then set up using the Agricultural Production Systems Simulator (APSIM) to explore the interactions between climate, crop management (sowing date and nitrogen fertilization) and rooting depth on grain yield and nitrate (NO3-N) dynamics. The analysis showed that a lack of optimal sowing dates that synchronize radiation, rainfall events and nitrogen (N) management with critical growth stages explained the low farm yields.

“…In Ghana, there are very few published field experimental results that show crop performance in biochar amended soils (e.g. Akoto‐Danso et al, ; Oppong Danso et al, ; Steiner et al, ). Akoto‐Danso et al () as well as Steiner et al () reported significant increases in maize and lettuce yield after amendment with 20 t/ha rice husk biochar.…”

“…However, both studies were carried out under rainfed conditions and no attempt was made to investigate how biochar interacts with soil moisture to affect crop performance. On the other hand, Oppong Danso et al () investigated the interactive effects of biochar with full irrigation and without irrigation and found the highest maize grain yield in the irrigated treatment amended with 30/ha rice straw biochar. None of the studies investigated biochar's interaction with deficit irrigation to affect crop growth and yield.…”

In order to determine whether the current low productivity associated with rainfed cultivation on degraded soils in Ghana can be improved by biochar amendment and irrigation, field experiments with maize were conducted over two seasons in 2017 and 2018. Rice straw biochar at rates of 0 t/ha (B0), 15 t/ha (B15) and 30 t/ha (B30) was combined with irrigation regimes of full irrigation (I100), deficit irrigation (I60) and no irrigation (I0). The I100 treatment was irrigated to field capacity every 3–4 days according to time domain reflectometry measurements while the I60 treatment received 60% of the irrigation amount given to I100 but with the same irrigation frequency. The I0 treatment was not irrigated. In both seasons, the B30 treatment recorded the highest total dry matter yield (TDMY), intercepted photosynthetically active radiation (IPAR) and radiation‐use efficiency (RUE) and these were significantly (p ≤ .05) higher than B0 except for RUE in 2017. Irrigation regimes did not significantly affect TDMY, IPAR and RUE in 2017 but compared to I100, I0 significantly reduced TDMY, IPAR and RUE in the relatively dryer 2018 season. Measured ratio vegetation indices differentiated biochar treatments earlier in the 2018 season than during 2017 and increase of leaf chlorophyll content indices with biochar rate in both seasons indicated that biochar amendment improved nitrogen uptake. Our study demonstrated that rice straw biochar is capable of increasing TDMY, IPAR and RUE of maize grown on degraded soils in Ghana. The study further showed that TDMY, IPAR and RUE of deficit irrigated maize for two seasons were similar to the counterpart fully irrigated maize and may be a viable water management option for farmers in Ghana to save irrigation water resources.
