“…However, using low N fertilization (30 kg N ha −1 ) and 46 kg ha −1 of superphosphate. Yeboah et al (2019) observed no significant effect of DT varieties and nitrogen fertilizer in farm conditions during the major and minor seasons. Kabate et al (2015), by reviewing the factors driving the doubling of maize yields in recent years in Ethiopia, showed that this was due to the adoption of modern (tolerant and high yielding) varieties coupled with the application of a small amount of nitrogen (34 kg ha).…”

“…The use of such improved maize varieties can help farmers to produce maize during the drought periods, especially when the drought occurs at the crucial crop development stages such as the flowering and grain filling stages. Their climatic endurance, highest yield, and grain quality were the strong points of their adoption (Yeboah et al, 2019). Varieties of DT maize are expected to improve the resilience of maize-based farming systems in Benin by enhancing food security, nutrition and farmer's income, and reducing poverty (Makate et al, 2017;Wossen et al, 2017;Abdoulaye et al, 2018;Lunduka et al, 2019).…”

In sub-Saharan Africa, smallholder farming systems continue to record very low yields despite the availability of appropriate crop management technologies. A 2-year field experiment was conducted in 2018 and 2019 at the Agricultural Research Station of Northern Benin to evaluate the growth response, grain yield attributes, and nutrient- and water- use efficiencies of different drought-tolerant (DT) maize varieties (TZEE-W-POP-STR QPM, TZE-Y-POP-STR, 2008Syn-EE-W DT-STR, and 2000Syn-EE-W of 80–90 days cycle), compared to DMR-ESR-W, a drought-susceptible (DS) variety of 90 days cycle, under different fertilizer options [no fertilizer control, microdosing option 1 (MD1, 25 kg N ha−1 + 4 kg P ha−1), option 2 (MD2, 25 kg N ha−1 + 8 kg P ha−1), option 3 (MD3, 35 kg N ha−1 + 8 kg P ha−1), and broadcast fertilizer at recommended rate (RR, 76 kg N ha−1 + 13 kg P ha−1). Generally, combining microdosing with DT varieties showed a very good performance by increasing the leaf area and biomass by 71 and 85%, respectively, at anthesis compared to the conventional practice. Microdosing increases grain and stover yields by 171 and 98%, respectively, compared to an unfertilized control with generally no difference between MD3 and RR treatments. Also, the DT varieties obtained the best yields (+19%), with the highest value observed with the TZE-Y variety. Significant interaction was found between varieties and fertilization for grain and stover yields. During the two cropping seasons, microdose fertilization increases the DT grain yield and gross return by 658 kg ha−1 and 203$USD, respectively, than their application on drought sensitive variety. The results of the current study demonstrated that there is a considerable potential for smallholder farmers of northern Benin to improve the maize productivity by means of DT varieties and of fertilizer microdosing. Using, especially, the MD3 option on the DT variety, TZE-Y, may be the best combination in optimizing the maize production in the sub-humid region of Benin, instead of the climate sensitive variety of the DMR-ESR under the microdosing or a common fertilization practice. However, further testing of the technologies through on-farm experiments are required before a precise advice can be given. Precisely, there is a need to evaluate these management options in farmer's fields, taking into account the climatic, soil, and management conditions to better assess and understand the variation in response and in economic benefits and risk.

“…Very few studies have investigated this subject in Ghana, mainly looking at the relationship between fertilizer adoption and crop yield [38][39][40][41][42]. Other studies have focused on the determinants of fertilizer (especially chemical fertilizer) adoption [43][44][45]. Tis study expands the scope to examine the impact on farm income, gross margins, and its commercialization potential in Ghana.…”

Organic fertilizer commercialization may present a great opportunity to help deal with the issue of solid waste management and help improve the declining soil problems in many developing countries. Ghana’s solid waste is predominantly organic, which is suitable for organic fertilizer production. This paper seeks to establish relationship between organic fertilizer usage and crop farm performance and assess its commercialization potential. The study employed a farmer-survey and key informant interviews to generate data from 300 farmers randomly selected across three regions in Ghana. The computed organic fertilizer use rate is 42% among farmers surveyed, and organic fertilizer is primarily used in vegetable and maize production. The estimated current demand for organic fertilizer is about 0.7 million t/annum with a potential to rise to about 2.7 million t/annum in the long term. This will however require sensitization on its importance, availability, and affordability. The study has established a strong relationship between organic fertilizer adoption and farm performance increasing yield by 57%, income by 53%, and gross margins by 63%. There is obviously a cost reduction when organic fertilizer is adopted. Organic fertilizer adoption was found to be mainly related to farmer base organization membership status, access to extension services, access to organic fertilizer, and transport cost. Organic fertilizer commercialization has the potential to make Ghana a net exporter of fertilizer and create sustainable jobs for the youth. We recommend the use of organic fertilizer by farmers and highly recommend the commercial production of organic fertilizer.

This study explores the causal association between organic and inorganic fertilizer application and vegetable productivity in Ghana. Primary data were obtained from 300 pepper, cabbage and lettuce producers. To correct for self-selection bias and endogeneity, Heckman selection and three-stage least-squares models were estimated. More producers used inorganic fertilizers for pepper, cabbage and lettuce production than those who used organic fertilizers. Vegetable producers applied higher quantities of organic fertilizers (2830 kg) per acre than inorganic fertilizers (880 kg). Organic cabbage and lettuce producers recorded higher productivity than inorganic producers, but inorganic pepper producers had higher productivity than organic producers. However, vegetable producers who applied either organic or inorganic fertilizers, or both, recorded higher productivity than those who did not apply fertilizer. Factors that enhance the application of organic and inorganic fertilizers and vegetable productivity are education, farm size and production for export, land ownership, farmer association membership and perception about fertilizer price. Organic and inorganic fertilizer application improves vegetable productivity, and productivity promotes fertilizer application. Private agencies and government should subsidize fertilizers, improve producers' access to agricultural information, and train producers on productivity-enhancing agronomic practices.
