“…To achieve this, a study of small-scale maize farmer's present level of efficiency and analysis of factors influencing their level of efficiency is necessary. It will suggest areas of resource use adjustments and allocation required for enhanced productivity as it has been observed that high production and productivity are a direct consequence of efficiency in input use and combination given the prevailing technology (Ogundari & Ojo, 2008).…”

Maize is the main staple food and cornerstone of Zambia's agricultural economy and as such, high productivity and efficiency in its production are critical to food security and poverty reduction in the country. This paper estimates the technical efficiency of maize producers in Zambia using Stochastic Frontier Analysis (SFA) and also determines the factors which influence technical efficiency in maize production. Primary data from 400 households in the Central Province of Zambia were used in this study. Results show that there exists opportunities to increase technical efficiency from the present level of inputs. The average technical efficiency was at 50%, with a minimum of 2% and a maximum of 84%. The distribution of the technical efficiency is such that 14% of the farmers have efficiency scores that are less than 30% while 46% of the farmers have technical scores above 50%, and 14% have technical efficiency scores above 70%. Maximum likelihood results showed that the age of a farmer, use of certified hybrid seed, access to loans and extension advice and off-farm income influence technical efficiency. The study recommends Government and other maize stakeholders to devise strategies for improving access to credit and extension services and promoting use of certified hybrid seed as a way to improve the technical efficiency of maize producers in Zambia.

“…Nigeria is an agrarian society in which agriculture remains the main occupation, as is the case in most of the Sub-Saharan African countries. It is the principal source of food and livelihood, making it a critical component of programmes that seek to reduce poverty and attain food security in the country (Ogundari and Ojo, 2005).…”

The objectives of the study reported in this paper were, first, to uncover how specific characteristics account for systematic variation in the reported average technical efficiency (ATE) estimates across frontier studies, focusing on Nigerian agriculture, and, second, to identify factors driving the efficiency level of the sector over the years. The literature used for meta-regression analysis (MRA) covers the 12-year period from 1999 to 2010. The findings reveal that the hypothesis of publication bias in the selected literature is rejected, while the reported mean ATE from the primary studies denotes a genuine effect. An overall mean ATE of 72% was obtained from all the studies, which implies that there is still room for improvement in the efficiency of Nigerian agriculture. The MRA result shows that the reported ATE increased significantly as input use and year of survey from the primary studies increased. Year of publication from the studies has a significant positive effect on the reported ATE estimates. Furthermore, the authors demonstrate that estimates in studies with a focus on cash crops appear significantly higher than in those focusing on non-cash crops. In addition, efficiency estimates of studies in the southeast and south are significantly lower than those from studies in the southwestern part of the country.

“…While, using the first plant distribution (D 1 ), i.e., planting maize plants on one side of terraces of 140 cm width with 20 cm between hills and leaving one plant/hill and planting watermelon pulp on the other side of the terraces resulted in the lowest values of all studied watermelon pulp growth, yield and its attributes in both seasons. These increments in growth, yield and its attributes of watermelon pulp with D 3 plant distribution may be ascribed to that plant distribution have great importance in the interception and efficiency of conversion of the photosynthetically active radiation intercepted by the canopy into seeds (Ogundari & Ojo, 2005). Also, these plant distributions can be reduce the use efficiency of water, light and nutrients by plants (Moyin-Jesu, 2012).…”

“…Intercropping is a common practice in Egypt, but the advantage compared to sole cropping depends on the crop plants and local agro-ecological conditions. Where, Moyin-Jesu (2012) reported that the intercropping systems can increase the land use efficiency and nutrient use efficiency, which resulting in higher yields Ogundari and Ojo (2005).…”

Two field experiments were carried out at the Experimental Farm of Gemmeiza Agriculture Research Station, Agricultural Research Center (ARC), Egypt after 2018 and 2019 summer growing seasons to determine the effect of intercropping pattern of yellow maize hybrid (single cross 168: “SC 168”) with watermelon pulp at three plant distributions (20 cm between hills and one plant/hill, 40 cm between hills and two plants/hill and 60 cm between hills and three plants/hill) and different levels of nitrogen fertilizer (25, 50, 75 and 100% of the recommended dose “120 kg N fad-1”) as well as their interactions on maize and watermelon pulp growth, yield and its attributes as well as competitive relationships and yield advantages. The experiments were carried out in split-plot design with four replicates. The main-plots were assigned to plant distributions of maize, the sub-plots were allocated to levels of nitrogen fertilizer for maize. The obtained results showed that planting maize plants on one side of terraces of 140 cm width with 20 cm between hills and leaving one plant/hill and planting watermelon pulp on the other side of the terraces produced the highest values of plant height, ear height, number of kernels row-1, 100-kernel weight and grain yield fad-1, at the same time the lowest values of ear leaf area, ear length, ear diameter and number of rows ear-1 of maize as well as the lowest values of growth, yield and its attributes of watermelon pulp during the both seasons. Mineral fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose produced the highest values of all studied growth characters, yield and its attributes of maize and watermelon pulp in both seasons. The highest values of land equivalent ratio (LER), relative crowding coefficient (RCC), area time equivalent ratio (ATER), land equivalent coefficient (LEC), aggressivity index (AI), monetary advantage index (MAI), actual yield (L.E.) of watermelon, Total income (L.E.) and economic return (L.E.) were obtained from planting maize plants on one side of terraces of 140 cm width with 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose in both seasons. It can be recommended that planting maize on 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 90 kg N/fad and watermelon pulp with the recommended dose to obtain the maximum values growth, yield and its attributes of watermelon pulp and competitive relationships and yield advantages of both crops under the climates conditions of Middle Delta, Egypt.
