Abstract

Along the maize value chain in Ghana are a wide range of risks that confront actors; the risk chain actors' face include production and marketing risks. Accordingly, risk management, which has become an integral part of maize value chain activities, is challenged with several factors, some of which are economic, institutional, social and behavioral factors. This study posits that risk preferences/behavior of farm decision-makers in the maize value chain have empirical importance for economic and policy analysis. Thus, an experimental gambling approach was used to elicit the risk aversion behavior of respondents (farmers). Here, the respondents' risk aversion behavior over varying game levels was investigated. The multinomial logit model was used to investigate endogenous and exogenous factors explaining the risk behavior. The data were obtained by interviewing 220 maize farmers who were sampled with a two-stage sampling procedure. This study revealed that most of the farmers in the study area exhibited risk aversion behavior. About 33% of farmers showed extreme risk aversion behavior at the games’ lowest level and increased to 45% as the game level rose. It was also found that sex, age, level of formal education, access to credit, access to the storage facility, household size, farm size and the number of extension visits to the farm significantly explained the risk aversion behavior the maize farmers exhibited. Because farmers are risk-averse and become more risk-averse as stakes become high, any farm innovations to be introduced to them must be implemented gradually, especially with the low-income farmers. It is also critical to make risk mitigation 'handles' available to farmers so that they can rely on them during times of risk.

Abstract

Salinity is a challenge in crop production. High salinity affects soil osmotic pressure and the balance of nutrients that inhibit plant growth. In such case, utilization of salt-tolerant rice varieties could be an alternative. This study aims to identify microsatellite markers associated with salt tolerance, compare the Inpari Unsoed 79 Agritan variety with ten other rice genotypes based on microsatellite markers and determine the qualitative composition metabolites in Inpari Unsoed 79 Agritan associated with the plant response to salinity. This research was carried out at the Laboratory of Plant Breeding and Biotechnology Universitas Jenderal Soedirman and Indonesian Institute of Sciences, Bogor. This research used eleven rice varieties and ten microsatellite markers. The identification of microsatellite markers consisted of genomic DNA extraction, quantification and qualification of DNA, amplification of microsatellite DNA and data analysis. Metabolite profiling was conducted on Gas Chromatography-Mass Spectrometry (GC-MS) instrument. The results showed that microsatellite markers RM 241, RM 515, RM 519 and RM 528 differentiate the Inpari Unsoed 79 Agritan from the IR 29 genotype. Microsatellite markers RM 129 and RM 292 distinguished the Nona Bokra from the IR 29 genotypes. The genetic relationship of eleven rice genotypes resulted in two clusters. The GC-MS metabolite compounds in Inpari Unsoed 79 Agritan are β-Alanine and trimethylsilyl ester β-Alanine, a derivative compound of β-Alanine. These findings suggested that microsatellite markers RM 129, RM 292, RM 241, RM 515, RM 519 and RM 528 were associated with salt-tolerant in the seedling stage.

Abstract

Over the years, there has been a continuous increase in the demand for tef (Eragrostis tef (Zucc.) Trotter) due to population growth, average incomes and urbanization in Ethiopia, but its innovation system has not been fully explored. This research aims to determine the supportive effect of tef innovation system on its investigation and development as well as the systemic constraints in the process. A coupled structural-functional innovation system analysis was used to explore the barriers faced in Central Ethiopia. The results revealed the constraints affecting the innovation system, namely limited capacity of existing actors, weak interactions and partnerships among actors, weak enforcement of institutions as well as inadequate/poor infrastructure. They also showed that technology development, technology diffusion, entrepreneurial activities, market development, resource mobilization and legitimacy creation have been the weak functions of tef innovation. Furthermore, a failure in one of the functions has a knock-on effect on others, which causes an overall dysfunctional innovation system. Based on the results, failures of the structural elements along with weaknesses of functions have constrained the development of tef innovation systems sector. A combination of technological, institutional and technical intervention must be implemented to overcome this problem.

Abstract

The increasing demand for rice and the increasing population growth rate require sustainable rice production. Direct seeding of rice (DSR) combined with the use of arbuscular mycorrhizal fungi (AMF) is needed to achieve sustainable food production. This study aims to determine the effect of the planting method and mycorrhizal inoculation on the diversity, composition and dominance of weeds in a rice field for the sustainability of agricultural production. The research used a split-plot design with three replications. The main plot was the planting method consisting of on row, drum seeder and transplanting, while the subplot was mycorrhizal inoculation divided into with mycorrhizal inoculation and without mycorrhizal inoculation. The observed variables were light penetration, weeds population, weeds composition, weeds biomass, summed dominance ratio and community coefficient. The results showed that there were 34 kinds of weeds consisting of 13 families and the dominant weed was annual weeds, most of which were broadleaf weeds. The dominant weed was Alternanthera sessilis (L.) R. Br. ex DC. (sessile joyweed). The planting methods affected the weed population in 24 days after sowing (DAS) and the composition of broadleaf weeds in 24 DAS but did not affect weed biomass. The AMF inoculation did not affect weed population, composition, or biomass. It is necessary to find mycorrhizal species that can affect weed growth.

Abstract

Seedlings is the initial part of seed plant’s growth and development including areca nut palm which germination is an essential part of it. Organic mulching is one of the utmost sustainable practices, therefore, it has been employed to enhance areca nut seedlings growth. The study aims to evaluate the effect of several types of organic mulch on areca nut seedlings shoot-root growth. The 3-month long experiment was conducted according to completely randomized design, with four treatments, namely no mulching (control) (M0), gliricidia (Gliricidia sepium) mulching (M1), imperata (Imperata cylindrica) mulching (M2) and lamtoro (Leucaena leucocephala) mulching (M3). The treatments were repeated 5 times with 20 experimental units. The findings revealed that no significant differences (p < 0.05) were found on the application of different organic mulching among all of the parameters. The treatment covered by imperata mulch tended to score the highest compared to other mulches on germination time, seedling height and shoot fresh weight while the minimum yield was recorded in M1 where gliricidia mulch was used. Application of organic mulch displayed better results for most of the parameters than that of the control resulting from an optimal growing environment for areca nut seedlings growth.

Abstract

The Klampok Sub-watershed flows in the Semarang Regency, Central Java, Indonesia, located in the upstream part of the Jragung Watershed, used as a source of irrigation. Klampok Sub-watershed experiences environmental pressures in the form of decreasing water quality because of various human activities. For this reason, this study aims to determine the changes in the water quality and pollution index of the Klampok Sub-watershed in 2016 and 2020. The water quality observations were carried out in 2020 utilizing the Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Nitrate, Zinc (Zn) and Copper (Cu) parameters. The laboratory analysis results were compared with water quality standards based on Government Regulation Number 22 of 2021 and the status of water quality based on the pollution index method under the Decree of the Minister of the Environment Number 115 of 2003. The study results showed a change in the quality and index of water pollution in 2016 and 2020. The study results revealed a decrease in the value of water quality on the parameters BOD, COD, Zn and Cu, which indicated that the water quality was improving. Moreover, the Klampok Sub-watershed pollution index decreased in 2016 and 2020 so that the Klampok Sub-watershed had quality criteria for lightly polluted water to moderately polluted to lightly polluted at each sampling point. Therefore, several efforts to control pollution and management of the Klampok Sub-watershed, such as community outreach, water quality monitoring and industrial compliance, are expected to improve so that the Klampok Sub-watershed's sustainability can provide various benefits to the community.

Abstract

Rainfed paddy fields have a great potential to be developed in Indonesia, especially in Central Java. However, water irrigation management, drought stress, pest and disease infestation and low nutrients that affect paddy yield remain the constraints. Unpredictable climate pattern is also a limiting factor in the cultivation of rainfed paddy fields. This narrative review aims to identify and discuss solutions to problems that exist to increase the yield of rainfed paddy fields with several techniques that support sustainable agriculture. This review paper was prepared by collecting government data and interviews with several farmer group leaders as complementary data. Based on field conditions, farmers in rainfed paddy fields provide fertilization inputs that are not following the fertilizer recommendations. Moreover, field conditions with limited water availability have caused paddy cultivating in several locations only once a year with low yields. Water storage can help farmers meet the need for water, especially during dry and water-stress conditions. The farmers also need to pay attention to the appropriate fertilization doses and the use of additional organic matter derived from cultivation residues, which are expected to increase the availability of nutrients in the soil. The use of short-life and drought-resistant varieties can aid in overcoming the problem of crop failure in the middle phase caused by water scarcity. Finally, we identify and emphasize that rainfed paddy fields generally have a limiting factor for water and nutrients and several technologies are needed to contribute to increasing more sustainable paddy yields.

Abstract

Agricultural products cause the emission of certain significant amount of greenhouse gases. Carbon dioxide (CO2) is one of the most important greenhouse gases and its emissions are increasing day by day as a result of the increase in agricultural productivity. This study aims to pinpoint the most environmentally friendly crops and fruits that are sources of good nutrients and emits less CO2 throughout their life cycles. Relation between nutrient availability and CO2 emissions from staple foods namely; wheat, maize, rice, potato, sugarcane, sugar beet, soybean, palm oil, sunflower, rapeseed, banana, apple and grape are investigated in this study. Secondary data was collected from dataset’s website. Spearman's rank and diagram interpretation technique are used to find out the correlation between nutrient availability and CO2 emissions. Among carbohydrate diets, rice emits 4 kg CO2 kg-1 of crops, which is significantly higher than that of wheat, maize and potato. However, the amount of carbohydrates in rice (0.26%) is less than those carbohydrate diets. Similarly, sugarcane emits more CO2 as 2.6 kg kg-1 of crops than sugar beet (1.4 kg kg-1 of crops) among sugar crops. Soybean and palm oil emit more CO2 as 6 kg kg-1 and 7.2 kg kg-1 of crops, respectively, as compared to other oilseed crops, but every oilseed crop has the same food value. Among fruits, bananas emit less CO2 (1.1 kg kg-1 of crops) and have a higher content of carbohydrates (0.23%) than other selected fruits. Proper crop selection based on nutrient content can lead to lower CO2 emissions than at present and a consistent balance between environmental and nutritional needs in the future.

Abstract

Induction of flowering is one of the efforts that can extend the production period of Chokun oranges. This study aims to determine the effect of the dose of paclobutrazol (PBZ), duration of drought stress and the combination of treatments that gives the best results on the Chokun orange (Citrus sp.). The research design used was randomized complete block design (RCBD), consisting of 3 replications. The treatment in this study was a combination of the dose of PBZ (control, active ingredient 0.75 g plant-1 and active ingredient 1.5 g plant-1) and duration of drought stress (control, 1, 2 and 3 weeks). The results show that the application of PBZ and duration of drought stress can induce the flowering of citrus plants as seen from the generative shoot variables with a quadratic model on the equation y = -17.778x2 + 31.556x + 26.667 at the optimum dose of 0.89 g plant-1 of active ingredient and 1 week of drought. The dry period of 3 weeks gives the best results seen from variables of the number of flowers and number of fruits. In general, the results suggest that the application of PBZ and duration of drought stress can transfer from the vegetative phase to the generative phase which in turn could induce the flowering of citrus plants.

Abstract

The Ethiopian government has made efforts to rehabilitate degraded lands using a range of sustainable land management (SLM) initiatives. One of the key components was the use of improved structural soil and water conservation (SWC) technologies. However, the effectiveness of technology adoption varies greatly among households and abandoning previously accepted measures is a typical occurrence. Thus, this study sought to discover factors influencing smallholder farmers’ decisions to abandon already accepted SWC measures. The analysis was conducted based on data collected from 525 sample households surveyed in two districts in Central Ethiopia. An ordered cumulative logistic (POM) regression model was used to examine variables explaining households’ decision behavior. The study findings have revealed that sampled households were at different adoption stages, i.e., dis-adopters (22%), pilot-level adopters (14%) and adopters (64%). The results from the POM model also show that a range of variables influenced farmers’ dis-adoption decisions. Factors such as awareness about the risks of land degradation, access to training, incentives, land fragmentation, gender, full-time labor size, gentle slope plots, economic returns on investment and post-adoption follow-up were found to substantially influence smallholder farmers’ adoption discontinuance decisions. Thus, policymakers should consider these variables in designing strategies to overcome barriers to SLM practices.
