Use Of Resources

This paper aimed to assess the technical efficiency of maize seed production and the major factors contributing on technical efficiency. Maize is the second most important staple crop in Nepal, but the average yield of maize is very low as compared to other countries having similar agro-climatic requirements.  Inefficient use of resources had led to low yield in maize crop. The software Raosoft was used to determine the required sample size and total of 182 samples were selected using simple random technique in June, 2016. Stochastic production frontier model and Tobit model were used to derive the results. The average technical efficiency of maize seed production ranged from 0.25-0.92 with an average of 0.71which revealed the scope of increasing technical efficiency by 29 percent. The majority of the farmers (29.1%) were at higher technical efficiency level of 0.8-0.9 followed by 28.6 percent at 0.7-0.8 and 23.1 percent at 0.6-0.7. Age and schooling of household head, experience on maize seed production, area shared by maize crop and dummies variables such as livestock holding, source of seed and access to extension service had found significantly affecting on the technical efficiency level. For the least developed country like Nepal it would be better to use the available resources wisely and improvement of existing technologies would be more cost effective than that of discovering new technologies. The study recommended that the concerned organizations should focus on mixed agricultural farming system, access to better quality seed and provide technical knowledge which would help in improving technical efficiency.

The study analysed the profitability of improved seed adoption on the profitability and technical efficiency of smallholder maize farmers in Abuja, Nigeria. Descriptive statistics were used to describe the socioeconomic characteristics, gross margin analysis was used to determine the costs and returns of maize production. The t-test was used to compare the yield of improved maize seed adopters and non-adopters. The logit regression was used to analyse the determinants of adoption. The stochastic production frontier model was used to determine the technical efficiency of IMV. The results revealed that the average age of respondents (adopters and non-adopters) was 48 years and 39 years, respectively. Furthermore, 56% and 66% were male, 75% and 93% were married with average household size of 6 and 7 persons, respectively, and majority had formal education. Adopters had a mean farm size of 1.95 ha, while non-adopters had a mean farm size of 1.76 ha. The gross margin analysis result showed the profitability index for IMV and local seed were 0.66 and 0.41, respectively. The t-test result showed that IMV had higher yield per hectare (2,713.66kg/ha) compared to local maize variety (1,281.33kg/ha). The result of maximum likelihood estimate showed that the mean technical efficiency was 0.56 and 0.49 for adopters and non-adopters, respectively. The study revealed that adopters of improved maize seed varieties earned higher profits and were more technically efficient than non-adopters. It recommended the strengthening of extension services to enhance adoption through awareness by government. Farmers should form cooperatives to enable resourceful negotiation for inputs. Also, an improvement in the research and development of high quality improved maize varieties should be encouraged.

AbstractWhere maize plays a critical role in food security, governments and donors have invested heavily in support of local, privately owned, often small and medium sized, maize seed enterprises (maize SMEs). Underpinning these investments are strong assumptions about maize SMEs’ capacity to produce and distribute seed to smallholders. This study assesses the capacities of 22 maize SMEs in Mexico that engaged with MasAgro—a large-scale development program initiated in 2011 that has provided maize SMEs with improved genetic material and technical assistance. Data were collected onsite from in-depth interviews with enterprise owners and managers and complemented with other primary and secondary sources. Overall, maize SMEs showed high levels of absorptive capacity for seed production, but limited signs of learning and innovation in terms of business organization and strategic seed marketing. Asset endowments varied widely among the SMEs, but generally they were lowest among the smaller enterprises, and access to business development services beyond MasAgro was practically nonexistent. Results highlighted the critical role of MasAgro in reinvigorating the portfolios of seeds produced by maize SMEs, as well as the challenges ahead for maize SMEs to scale the new technologies in a competitive market that has long been dominated by multinational seed enterprises. Among these challenges were limited investment in seed marketing, weak infrastructure for seed production, and limited experience in business management. Achieving the food security goals through maize SMEs will require making national maize seed industry development a strategic imperative.

The cereal crop, maize is regarded as staple food mainly in hill areas of Nepal. Seed is one of the vital input which determines the production and yield of any crop. Farmers are found using the required inputs in haphazard way which had increased the cost of production and inefficiency of resources used. The study on seed sector is limited. For such a backdrop, this study was aimed to assess the level of technical efficiency (TE) of certified maize seed production. The total of 164 certified seed producer were interviewed in June, 2016 using simple random sampling technique in Palpa district of Nepal. The result revealed that increase in amount of seed and labor by one percent would increase the yield of certified maize seed by 0.29 and 0.34 percent respectively. The TE was estimated using stochastic production frontier model in Stata software. The average TE was found 70 percent which revealed the scope of increasing TE by 30 percent using the existing available resources. There were about 29 percent farmers who had TE of ≥0.7-0.8 followed by 27.44 percent at ≥0.8-0.9. Government and other stakeholders should prioritize to provide technical knowledge via training and increase the visit of extension worker to increase TE of certified maize seed producer in the district.

The level of purse seine business income is determined by the efficient allocation of resources for alternative capture fisheries activities. If resources are not used efficiently, there will be unexploited potential to increase income and create surpluses. Conversely, if resources are allocated efficiently, additional capture fisheries can be obtained through growth-oriented development efforts. Therefore, it is important to identify the efficient use of resources to determine the existence of purse seine fisheries. The results show that the estimated technical efficiency of the catch with SPF (Stochastic Production Frontier) analysis for purse seine fisheries in Central Maluku Regency and Ambon was influenced by the length and width of fishing gear, number of fishermen, amount of investment value and time of capture operations. The minimum value of catch technical efficiency is 0.10 and the maximum is 0.99 with an average 0.48. Factors influencing the technical inefficiency of fishing are the experience of captain and the education level of fishermen. Purse seine fishery business in Central Maluku Regency and Ambon City is feasible to be developed, showing by NPV value Rp. 30,514,684 / year, IRR 23.97% and B / C ratio 5.85. The average return on investment (PP) based on the analysis is 2.16 years, with BEP price Rp. 6,606 and BEP production 3,765 kgs. The main priorities of purse seine fisheries development policy strategy in Central Maluku Regency and Ambon are the development of assistance to fishing groups, the development of appropriate technology to handle catches, increase fisheries production, and infrastructures development.

Maize is the second most important staple crop in Nepal. Its demand is rapidly increasing due to a growth in the poultry sector. The national maize yield is low, leading to insufficient domestic production and thereby increasing imports. Maize seed is considered as one of the crucial inputs in achieving the targeted yield growth, but usually is in short supply during the cropping season. Farmers are involved in maize seed production, which eases its supply. Thus, understanding the efficiency of maize seed production will have a direct impact on the efficiency of the country’s maize production. This paper aimed to assess the technical efficiency (TE) of maize seed production and the major factors affecting TE. Semistructured questionnaire survey was administered in June 2016 to 182 maize seed farmers selected randomly from a total of 260 maize seed growers in Palpa District, a leading maize seed producing district in the mid-hills of Nepal. TE is estimated based on the stochastic frontier production model, and the factors affecting TE are assessed using the Tobit model. TE ranged from 0.25 to 0.92 with an average of 0.71. This revealed the scope of increasing TE by 29%. TE in the study area is largely affected by the age and schooling year of household heads. Similarly, the experience of maize seed production, livestock holding, the share of maize seed area, seed source, and access to extension services affect TE. Hence, a focus on motivating experienced educated maize seed growers to expand the maize seed production area supplemented by a better seed source and extension services would contribute to improving TE.

The Impact

While there is growing recognition of the positive role played by organic farming in the reduction of the negative externalities due to conventional agriculture, there is uncertainty about the effect of the latter on the economic performance of the farms. In this scenario, the present paper aims at investigating the effect of organic farming on technical efficiency in Italian olive farms. A cross-section dataset was analyzed through the stochastic frontier function, where the adoption of organic farming was explicitly modeled. Then, to obtain an unbiased estimate of the impact of organic farming on technical efficiency, a propensity score matching method was implemented. The findings reveal that organic farming increases technical efficiency in Italian olive farms by approximately 10%. The highest impact of organic farming is observed in small farms. As for the propensity to become organic, we found that the production and the direct sales of a higher quality of gross marketable output, as well as the intensity of labor and machines, increase the probability to adopt organic farming. Conversely, farm localization, the availability of family labor, and financial capital discourage conversion to the organic farming system.

The sequence of the preceding crops in a no-tillage farming system, could interact with the integrated use of mineral and organic nitrogen (N) sources in a way that improves the growth and productivity of the terminal maize crop, meanwhile, enhancing its N use efficiency (NUE). In the current study, six legume-cereal crop sequences, including faba bean, soybean, Egyptian clover, wheat, and maize were evaluated along two experimental rotations that ended up by planting the terminal maize crop. In addition, the effects of applying variable mineral nitrogen (MN) rates with and without the incorporation of farmyard manure (FYM) on the productive performance of maize and its NUE were tested. The field experiments were conducted in a no-tillage irrigated farming system in Northern Egypt, a location that is characterized by its arid, Mediterranean climate. Results revealed that increasing the legume component in the evaluated crop sequences, up to 75%, resulted in improved maize ear leaf area, 1000-grain weight, and harvest index, thus, a higher final grain yield, with the inclusion of Egyptian clover was slightly better than faba bean. Comparing the crop sequences with 50% legume contribution uncovered the positive effects of soybean preceding crop on the terminal maize crop. Substituting 25% of the applied MN with FYM resulted in similar maize yields to the application of the equivalent 100% MN rates. The fertilizer treatments significantly interacted with the crop sequences in determining the maize grain yield, where the highest legume crop contribution in the crop sequence (75%) equalized the effects of the different fertilizer treatments on maize grain yield. The integrated use of FYM with MN in maize fertilization improved the NUE compared to the application of MN alone. Comparing fertilization treatments with similar MN content, with and without FYM, revealed that the difference in NUE was attributed to the additional amount of FYM. In similar conditions to the current study, it is recommended to grow faba bean two years before maize, while Egyptian clover could be grown directly preceding maize growth, with frequent inclusion of soybean in the sequence, this could be combined with the application of an average of 200 kg MN ha−1 in addition to FYM.

AbstractSoil microbe is crucial to a healthy soil, therefore its diversities and abundances under different conditions are still need fully understand.The aims of the study were to characterize the community structure and diversity of microbe in the rhizosphere soil after continuous maize seed production, and the relationship between the disease incidence of four diseases and the variation of the rhizosphere microbe. The results showed that different fungal and bacterial species were predominant in different cropping year, and long-term maize seed production had a huge impact on structure and diversity of soil microbial. Ascomycota and Mortierellomycota were the dominant fungal phyla and Mortierella and Ascomycetes represented for a large proportion of genus. A relative increase of Fusarium and Gibberella and a relative decrease of Mortierella, Chrysosporium, Podospora, and Chaetomium were observed with the increase of cropping year. Pathogenic Fusarium, Curvularia, Curvularia-lunata, Cladosporium, Gibberella-baccata, and Plectosphaerellaceae were over-presented and varied at different continuous cropping year, led to different maize disease incidence. Proteobacteria and Actinobacteria ranked in the top two of all bacterial phyla, and genus Pseudarthrobacter, Roseiflexus and RB41 dominated top 3. Haliangium and Streptomyces decreased with the continuous cropping year and mono-cropping of maize seed production increased disease incidence with the increase of cropping year, while the major disease was different. Continuous cropping of maize seed production induced the decrease of protective microbe and biocontrol genera, while pathogenic pathogen increased, and maize are in danger of pathogen invasion. Field management show great effects on soil microbial community.
