Economics of bulk storage techniques: maize and cowpea storage in Ghana

High postharvest loss is one of the major challenges faced by farmers in many African countries in their efforts to achieve food and nutrition security. Several postharvest techniques have been developed and introduced to farmers aimed at reducing food losses. This study evaluated the economic viability of four such grain storage techniques using capital budgeting techniques. Two grain protectants were applied at recommended rates in three treatment combinations to jute sacks, PICS sacks, polytanks, and poly sacks at different treatment levels and at different discount rates. Under maize storage, the net present value of all treatments yielded positive net returns. The polytank technique proved to be the most economically viable storage technique, followed by PICS and then jute sacks. Under cowpea storage, polytank proved to be the most viable, followed by PICS. This is consistent under replacement chain method and equivalent annual annuity under the three different discount rates used. Cowpea is best stored in polytanks and PICS sacks. Polytank is recommended as the most economically viable storage technique for both maize and cowpea storage. PICS is also recommend for both maize and cowpea storage. However, jute sacks and poly sacks are not suitable for cowpea storage even under chemical treatment, especially under long-term storage (over 6 months). The choice of storage technique should consider the commodity under consideration

Utilization of organic fertilizer in Ghana: implications for crop performance and commercialization

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

Impact of Irrigation Ecology on Rice Production Efficiency in Ghana

Irrigation production is a means by which agricultural production can be increased to meet the growing food demands in the world. This study evaluated the effect of irrigation ecology on farm household technical, allocative, and economic efficiency of smallholder rice farmers. Cross-sectional data was obtained from 350 rice farmers across rain fed and irrigation ecologies. Stochastic frontier analyses are used to estimate the production efficiency and endogenous treatment effect regression model is used to estimate the impact of irrigation ecology on rice production efficiency. The impact of irrigation ecology on technical efficiency is about 0.05, which implies farmers producing under irrigation ecology are more technically efficient in their rice production than those in rain fed production. The impact of irrigation ecology on allocative efficiency is about 0.33, which shows that farmers participating in irrigation farming are more allocatively efficient in their rice production than those in rain fed production. The impact on economic efficiency is about 0.23, meaning that farmers participating in irrigation farming are more economically efficient in their rice production than those in rain fed production. Irrigation ecology has positive impact on production efficiency; hence farmers should be encouraged to produce more under irrigation for increased yield and profit

Impact of contract farming on rice farm performance: Endogenous switching regression

Contract farming (CF) is increasing been used as a strategy in rice production in Ghana while there is no empirical data supporting it. This study investigated the importance of CF in rice production. Cross-sectional farm household level data collected from 350 rice farmers randomly selected across the rice production areas of Ghana was used. The adoption and casual impact of CF was estimated using endogenous switching regression and propensity score matching methods. Results revealed positive and significant relationship between CF and farm performance measures (yield and gross margins). Results indicate that, CF increases yield and gross margins significantly. It further identified educational level, rice farm size and ISFM as positive determinants of contract participation. This evidence provides strong support for efforts to promote CF in Ghana. Educated farmers should be targeted for CF participation because their propensity to participate in CF is high. Sensitising our illiterate farmers to participate in CF should be vigorously pursued. CF should also be encouraged as a means to promote the adoption of ISFM technology. CF is recommended as a good tool for developing the local rice value chain in Ghana

ARPN Journal of Agricultural and Biological Science ECONOMICS OF COMBINING ORGANIC AND IN-ORGANIC FERTILIZERS FOR MAIZE PRODUCTION UNDER TWO TILLAGE SYSTEMS IN THE NORTHERN SAVANNA ZONE OF GHANA

ABSTRACT Soils in the northern savanna zone of Ghana are poor in plant nutrients and are prone to compaction. Some amount of tillage and the application of fertilizers to enhance crop yields are necessary. The performance of maize on two tillage systems (Manual and bullock plough) with the application of different fertilizers was assessed for two years by a field experiment laid in a split-plot design with four replicates. The main plots were manual and bullock plough while the sub-plots were NPK (64 kg N/ha, 15 kg P205/ha and 15kg K20/ha), 6 tons/ha of animal manure, half the rate of in-organic and half the rate of animal manure and no fertilizer as the control in 2008 and 2009. The results showed that tillage loosened the soil and thus reduced soil bulk density, increased porosity and could have enhanced the availability of water and nutrients for better crop growth. The results further revealed that the application of animal manure alone increased maize yields in the second year by 57% as compared to 25% and 35% for the recommended fertilizer rates and half the rates respectively. However, maize yields from the recommended fertilizer rates and the half rates of both in-organic fertilizers and animal manure in each year were similar but significantly (p<0.05) higher than the manure and the control treatment plots. The application of recommended in-organic fertilizers rates gave yields which were similar to yields obtained from half rates of the in-organic and animal manure but for sustainability, the combination of both could be recommended to farmers for adoption. Comparably, the net benefit-cost ratios of both tillage systems are more than 1 indicating that maize production on each of them is profitable; however the bullock tillage system is a better option as it had higher net benefit-cost ratios in each year than the manual system

Interdependence of Extension and Improved Variety Adoption

This paper, seeks to empirically establish the complementarity or otherwise between the decision to adopt improved soybean variety and the decision to participate in extension service training. The paper departs from the traditional binary dependent regression model (probit and logit) with extension treated as one of several covariates and instead model the binary outcomes of the decisions to adopt improved varieties, and access to extension services simultaneously using bivariate probit model. Data for the study is from 1432 farmers across the three regions of northern Ghana to jointly model the determinants of access to agricultural extension services and adoption of improved soybean variety (Jenguma). We found a positive correlation between the decisions to adopt improved soybean variety (Jenguma) and access to agricultural extension services. The implication is that, the decision to adopt the variety is interrelated with access to agricultural extension services. Hence, access to agricultural extension services is complementary to the decision to adopt new soybean varieties. Findings also indicate that, the decision to adopt improved soybean varieties is influenced by younger, less educated farmers with large farms and ownership of parcels. Given that agricultural extension service is a public good, we recommend that the government of Ghana allocates more human, financial, and technical resources to the extension services to enhance the delivery of extension services to farmers so as to improve the adoption of productivity enhancing technologie

Fertilizer Adoption and Use Intensity Among Smallholder Farmers in Northern Ghana: A Case Study of the AGRA Soil Health Project

Northern Ghana is characterized by food insecurity largely due to over reliance on rain-fed agriculture under low farm input conditions. The present study investigated the effect of factors influencing mineral fertilizer adoption and use intensity among smallholder farmers in Northern Ghana. A total of 330 smallholder farmers selected through multi-stage sampling technique were interviewed. Adoption of fertilizer technology was determined by age, nativity, farm size, access to credit, and distance to agricultural office. The result of the truncated regression estimates indicated that income of household head, membership of farmer association, distance to agricultural office, access to input shop, income earning household that do not participate in agricultural development project and income earning male headed household were the significant factors influencing fertilizer use intensity. Distance to agricultural office was a key positive determinant of fertilizer adoption and use intensity. The study recommends improvement in road infrastructure and technical training of agricultural extension agents. Farmer based organization must be trained on regular basis to enhance their productive skills and technology uptake
