Abstract

Climate change, which exposes farmers to low productivity, crop failure and worsens food insecurity in developing nations has become a core challenge in Nigeria. These extremes have increased the vulnerability of several arable crop farmers due to inadequate mitigation strategies and restricted access to capital. This study analyzed climate change adaptation among cassava farmers in Okigwe agricultural zone of Imo State, Nigeria.  Perception of cassava farmers towards climate change, their adaptation strategies and challenges to climate change adaptation and determinant of farmers’ adaptation to climate change were the main objectives. A multi-stage random sampling procedure was used in selecting one hundred and twenty respondents for the study. Data were collected using structured questionnaire and analyzed with percentages, mean and Chi square. Results showed that the mean age of the respondents was 47 years while 78.30% of them had formal education.  The main adaptation strategies included planting on mounds (20%), diversification to non-farm activities (15%) and planting of improved varieties (14%). Cassava farmers in the study area perceived climate change as increase in heat waves (x̅=2.26), rainfall (x̅=2.76) and drought (x̅=2.35). The major challenges to adaptation were unsatisfactory weather reports (89.5%), lack of funds (82.4%) and inadequate extension contact (81.2%). Extension contacts and access to credit were the most significant determinants of utilization of climate change adaptation strategies. The study concludes that respondents are aware of climate change with diverse adaptation strategies and recommends that government and agricultural development agencies should integrate the determinant of climate change adaptation and mitigation into policies and programs relating to climate change resilience.  It also recommends that the availability of climate change information in real time, mobilization of more extension workers and provision of funds to improve the capacity of cassava farmers for climate change resilience should be prioritized

Abstract

Nutritional status is the end result of the balance between the food that enters the body (nutrient input) and the body's need (nutrient output) for those nutrients. In other words, the state of the body as a result of food consumption and the use of nutrients. Nutrient requirements are determined by many factors, including: basal metabolic rate, growth rate, physical activity, and relative factors, namely: ingestion, differences in absorption, utilization, and differences in excretion and destruction of nutrients in the body. A sample of 82 children aged between 2.5 and 5.0 years and 114 households representing adulthood was observed in two villages with Maudu' rituals, and 99 and 134 households in two villages without Maudu' rituals. The research was conducted in Cikoang Village, Takalar District. The results of this study indicate that the nutritional status of children under five in Cikoang Village is not good and needs attention from related parties in helping to improve child nutrition in Cikoang Village.

Abstract

Extracting total RNA from plant tissue using the conventional isolation method is time-consuming, requires expensive reagents and produces low-quality RNA. Over time, researchers have used many commercial RNA extraction kits on silica column-based to obtain high-quality RNA so that the isolated RNA can further use for sequencing and quantitative PCR analysis. This study aimed to identify the efficient apple leaf extraction method with high concentration and good quality RNA extraction. In this study, we applied four isolation kits to extract RNA from apple leaves, such as NucleoSpin® RNA Plant Kit (Macherey-Nagel), Quick-RNA™ Miniprep Kit (Zymo Research), PureLink® RNA Mini Kit (Ambion), and RibospinTM Plant Kit (GeneAll). The results showed that apple leaves RNA isolation successfully using the RibospinTM Plant Kit (Geneall) reagent with a concentration of 59.9±12.3 ng/µl in good RNA integrity. So, these isolated RNA can be used for further analysis.

Abstract

Rice is an important commodity for main staple in Indonesia. The need for rice will increase so that efforts are needed to increase its production. The use of superior varieties is an option to optimize land use whose area is increasingly limited due to population growth. The development of varieties is not only considered in terms of food production but is developed as an ingredient to meet nutritional needs. One of the local rice varieties that have the potential to be developed is Toraja local red rice (Pare Lea). Development of local rice character improvement through mutation breeding. Selection of superior genetypes is not only based on high production characters, but also the necessary information related to the relationship between characters that support production. This study aims to obtain information about the relationship between the components of growth and production of Toraja local red rice. This experiment used 9 mutant lines at fourth generation (M4)  as treatment and 1 non-mutant line as control. Agronomic characters that can support rice production were such as plant height, panicle length and grain yield per plant

Abstract

Quail agribusiness entrepreneurship venture is a minimal expense, exceptionally simple and high benefit business. Up till now, the investment of agribusiness in quails is not yet famous. This study aimed to examine the quail agribusiness entrepreneurship in Nigeria. Cross-sectional data were obtained from 164 quail agribusiness entrepreneurs selected through a multi-stage sampling procedure. Descriptive and inferential statistics were used for data analysis. Results showed that the major motives for the agribusiness entrepreneurs' venture in quail agribusiness were that quail agribusiness and its egg production investment is profitable (23.78%). The technical information on quail production was mainly sourced from their associates/poultry-related agribusiness entrepreneurs (31.10%) and 59.76% had interactions with the agricultural extension officers while 40.85% obtained their funds to finance the quail agribusiness from their savings. The identified most prevalent constraint always faced by the quail agribusiness entrepreneurs include the inaccessibility to supply centres and markets (3.89) which necessitated the major training needs of quail meat processing and handling of quail eggs (26.22%). The study concluded that the age of the quail agribusiness entrepreneurs (r = 0.42; p≤0.05), their gross margin per production cycle (r = 0.85; p≤0.05) and their years of experience in quail agribusiness (r = 0.71; p≤0.05) are important contributors in determining the stock size of quails reared Nigeria. It was recommended that stakeholders in the quail agribusiness in Nigeria should improve their business capacity through collective capacity building/training programmes and awareness creation on production and the nutritional and medicinal value of quails.

Abstract

Socio-culture is increasingly recognized as an important part towards sustainable food production and consumption.  This evolution is reflected in the fact that socio-culture is now generally referred to as one of the main drivers of sustainable food production and consumption. This study focuses on socio-cultural aspects in relation to the food production subsystem and food consumption subsystem in highland communities in West Sinjai District, Sinjai Regency, South Sulawesi Province. Using a qualitative approach, case study method, with data collection techniques, in-depth interviews, full observation, documentation and triangulation. So that it can see in depth the socio-cultural reality of the highland community. The socio-cultural apparatus is one of the supporting factors in the realization of the sustainability of food production and consumption in highland communities. The socio-cultural apparatus is one of the supporting factors in realizing the sustainability of food production and consumption in upland communities.  The socio-cultural component in the food production of highland communities strongly emphasizes the value of togetherness, the value of mutual cooperation and religious values. These values are implemented into food production activities from land preparation to harvesting such as; "Appada Elo"; "Appatinro Bine"; "Passibaling"; "Ganre Pare Beru".  The socio-cultural component of food consumption in highland communities also emphasizes religious values (a symbol of gratitude to the creator and getting closer to their ancestors), the value of togetherness (serving food to others as a form of respect and appreciation) and prestige values (types of food such as: local varieties of brown rice). These values are wrapped in community norms that have been maintained for generations as an effort to maintain the sustainability of community food production and consumption

Abstract

Over the years, the consumption of vegetables has grown. Due to growing consumer concern over health-related issues, this has happened. The purpose of this study is to investigate the patterns in vegetable consumption and exploration of the underlying factors for that existing pattern. In this study, information was gathered from household surveys. Data was analyzed using multinomial logistic regression and descriptive analysis. The majority (76.6%) of the respondents had up to seven family members. one-third of the sampled population falls in the service sector of the economy (43%). most of the sample households were from rural backgrounds (55.9%). Around (87.8%) of the sample population consumed less than 3 servings of vegetables in a day.  The quantity of vegetable consumption as a dependent variable has three categories less than, greater than, and equal to three serving sizes. While taking greater than three serving sizes as a reference category and less than three serving sizes as the dependent variable. It was found that as the family size increases from three members to more than that there is a likelihood increase in taking vegetables more on a per capita basis per day with an odds ratio of 0.21(0.4-0.9), similarly there is a likelihood increase in the vegetable consumption with the increase in monthly income 0.5(0.12-0.95), as the frequency of buying vegetables increases there is an increase in vegetable consumption, accessibility has also significant bearing on its intake. Due to less access to the marketplaces, rural residents have low trips to grocery shops and rely mostly on homegrown vegetables. Respondents from urban residents have frequent trips to the grocery shops mostly due to the availability of vegetables. The results show that implementing an appropriate pricing strategy and promoting market infrastructure will augment the dietary diversity in the population which will lead to the holistic development of the vegetable industry as well as the required nutritional needs efficiently.

Abstract

This study examines the contestation among actors responding to government policies in broiler farming. The research method employed is qualitative. A comprehensive investigation into each actor’s characteristics allows for a thorough understanding of unfolding contestation. The study took place in Blitar, East Java, Indonesia. The results indicate three key actors: the integrator farm, the independent farm, and the family farm. An integrator functions as an investor; while an independent consists of breeders with land, resources, and labour. Family farmers are operated by individuals with limited production capacities.  The government, aiming to ensure a stable supply of livestock for domestic consumption, utilizes its legislative authority to facilitate investment prospects in Indonesia.  Integrator farmers seize this opportunity to dominate broiler arming, compelling their actors to align with their interests. Independent farmers safeguard their interests through collaborative partnerships, whereas family farmers can only express their discontent with the government through protests.

Abstract

This study aims to calculate the production and income derived from farming several sweet potato varieties. The research was conducted in Bersehati Village, Tanah Miring District, Merauke Regency. The Research location was chosen purposively with the consideration that Kampung Bersehati is the largest sweet potato producing area in Merauke Regency. In total there are 157 sweet potato farmer populations, the number of samples taken was 20% of the population or 31 farmers.  Data analysis was conducted using the concept of cost, revenue, farm income, feasibility and analysis of the average difference test. The results showed that the yield per growing season of the Cakar variety (1,603 kg) was higher than the Local variety (1,599 kg). However, farming the Local variety yielded a higher income (IDR 4,672,140.96) than the Cakar variety (IDR 4,475,777.98) at a selling price of IDR 6,000 per kg. The feasibility analysis showed that both the Local variety (R/C Ratio 1.95) and the Cakar variety (1.87) are worth trying. The difference test analysis revealed significant differences in production and income between the two varieties.

Abstract

The sterilization is a primary step in in-vitro culture. plant breeding through in-vitro culture hinges on the successful effectiveness of the sterilization method in producing sterile plants. This research aims to optimize sterilization methods using a completely randomized factorial design. The first factor is the size of the material (small and large), and the second factor is the graded concentration of the bleach solution. The study revealed that Material sizes do not have a significant effect on contamination level, all the same, large size materials increase the survival rate of sterilized rodent tuber plants. The application of graded bleach solution concentrations at 25%, 20%, and 15% is able to reduce contamination to 0% on small size materials and 5 % on large size materials. Material sizes do not have a significant effect on contamination level, all the same, large size materials increase the survival rate of sterilized rodent tuber plants.
