Food security is an increasingly serious problem worldwide, and especially in sub-Saharan Africa. As land and resources are limited and environmental problems caused by agriculture are worsening, more efficient ways to use the resources available must be found. The objective of this study was to display the spatial variability in crop yield and resource use efficiencies across Nigeria and to give recommendations for improvement. Based on simulations from the crop model LINTUL5 we analyzed the influence of fertilizer application on the parameters Water Use Efficiency (WUE), Fertilizer Use Efficiency (FUE), and Radiation Use Efficiency (RUE) in maize. High spatial variability was observed, especially between the north and the south of the country. The highest potential for yield improvement was found in the south. While WUE and RUE increased with higher rates of fertilizer application, FUE decreased with higher rates. In order to improve these resource use efficiencies, we suggest optimizing management strategies, demand-oriented fertilizer application, and breeding for efficient traits.

The study examined the resource use efficiency of maize production in rainfed and irrigated conditions in Kaski, Nepal. It focused specially on the production function of maize, resource use efficiency and socioeconomic characteristics of the farmers. A well-structured interview schedule was used in this study. Out of the 368 households interviewed, 165 farmers cultivated maize and a total of 157 farmers (59 from irrigated and 98 from rainfed) provided useful data. The data analysis was done by using Microsoft excel and SPSS. Cobb-Douglas production function was used to determine the resource use efficiency of maize production.  Compared to rainfed system, maize productivity in irrigated system was higher despite the use of fewer input implying irrigation. Increase in seed use by 10% increased the yield by 1.9% in case of rainfed system and 0.05% in case of the irrigated system. The major implication for the study is that farmers should make proper utilization of their resources to achieve higher level of resource use efficiency.

This study investigates the resource use efficiency in the production of maize by small-scale farmers in Mwanza region. Specifically, the study seeks to determine what the resources that farmers use in maize production and also seeks to determine the challenges that farmers face in maize production in the study area. This study was conducted in two districts of Mwanza region. In each of the district, the study sampled three wards and randomly selected twelve small-scale farmers from each of the three wards selected. In total 72 small-scale farmers were selected from whom the data was collected. A Cobb-Douglas production function was used to fit and analyse the data for its good fit. The R² was 0.77, indicating that 77 percent of the variation in dependent variable was explained by the independent variables of the model. The use of inputs in the production of maize was noted to be increasing returns to scale. The results indicated that variables land (X1), labour (X2), age (X6), and experience (X8) were all positive and significant at the 1% while soil preparation (X4) variable was negative but significant at the 5%. The major constraints to maize production included lack of fertilizer (manure), finance (capital) and access to land. The study concluded that more exposure of small-scale farmers to frequent extension services is important to assist them to produce efficiently.

Abstract In sub-Saharan Africa, multiple plant nutrients deficiency besides N and P is a major growth-limiting factor for crop production. As a result, some soils become non-responsive for Rhizobium inoculation besides P application. Based on the soil test result, the soil of experimental sites had low OM, N, P, S and Zn. Hence, an experiment was carried out on-farm, during 2016/17 growing season, at Gondar Zuria woreda in Tsion and Denzaz Kebeles to evaluate the effect of Rhizobium inoculation, S and Zn application on yield, nodulation, N and P uptake of chickpea. The experiment included twelve treatments developed via factorial combination of two level of inoculation (Rhizobium inoculated, un-inoculated), three level of S (0, 15, 30 kg Sulphur ha-1) and two levels of Zn (0, 1.5 kg Zinc ha-1). The treatment was laid out in randomized complete block design with three replications. Results showed that the highest mean nodule number (15.3) and nodule volume (1.3 ml plant-1) over locations were obtained with Rhizobium inoculation integrated with 15 kg S and 1.5 kg Zn ha-1 which resulted in 37.8% and 116.7% increment over the control check, respectively. It was also observed that combined application of Rhizobium and 30 kg S ha-1 caused the highest (6.7) mean nodulation rating and seed yield (1775.5 kg ha-1) over locations which resulted in 86.1% and 28 % increase over the control check, respectively. Moreover, this treatment improved P use efficiency of chickpea. On the bases of observed result, it can be concluded that the response of chickpea to Rhizobium and P application can be improved by S application and Rhizobium inoculation with application of 30 kg S ha-1 with recommended rate of P and starter N is recommended for chickpea production at the experimental locations in Gonder Zuria Woreda.

The Impact

To simultaneously enhance agricultural productivity and lower negative impacts on the environment, food systems need to be much more efficient in using resources such as land, water, and fertilizer. This study examines resource use efficiency of maize production among smallholder farmers in Nyando, Kenya. The main objective is to assess the degree of technical efficiency of smallholder farmers and identify the impact of so-called “climate smart practices” on technical efficiency. The method of Stochastic Frontier Analysis is used to simultaneously estimate a stochastic production frontier and a technical inefficiency effect model. Data for 324 subplots farmed by 170 households were available for this analysis. The study reveals that maize production in Nyando is associated with mean technical efficiency of 45% and that soil conservation practices such as residue management, legume intercropping, and improved varieties significantly increase farmers’ technical efficiency. Soil carbon is found to be a critical factor of production. These results imply that there is potential to more than double production using the same resources and that soil conservation practices can be very “climate smart,” at once increasing soil carbon, production, climate resilience, and technical efficiency.
