Abstract

Climate change, as manifested through its multifaceted dimensions encompassing economic, social, and security effects, on agricultural activities within the Jordan Valley region. The research sample encompassed a group of 9000 agricultural practitioners residing in the Jordan Valley region. Employing the well-established Morgan model, a representative subset of 368 individuals was selected through a random sampling technique. The questionnaires were disseminated among the participants of the study, resulting in the retrieval of a total of 350 questionnaires. Upon careful examination, it was determined that 340 of these questionnaires were deemed valid and suitable for analysis. A meticulously crafted survey instrument was devised to systematically gather firsthand information. The research employed a quantitative (descriptive analytical) methodology to examine the data and evaluate hypotheses by employing suitable statistical techniques available in the Statistical Package for Social Sciences (SPSS). The findings of the study indicate a noteworthy and statistically significant relationship between climate change and agricultural operations. The analysis yielded a substantial coefficient of determination (R²=68.5%), suggesting that approximately 68.5% of the changes observed in agricultural operations can be attributed to the influence of climate change. The study proposes a strategic approach to enhance farmers' understanding of the indirect impact of climate change on various economic sectors, including manufacturing, energy production, transportation, and other services. This can be achieved through the implementation of educational initiatives, such as seminars and awareness sessions, which actively engage farmers in the learning process.

Abstract

Ginger has the potential for export and increased income for farmers in Nepal. Proper post-harvest handling practices has led to low market prices and significant post-harvest losses of ginger. The study was conducted in Palpa district to examine the post-harvest practices and technology adoption among ginger farmers. Data from 66 farmers in Bagnashkali, Purbakhola, Nisdi, and Rampur municipalities was collected through interviews, key informant interviews, and focus group discussions. Descriptive analysis was performed using MS Excel and SPSS. Results showed that 72.7% of farmers practiced storage, with Bhakari (60.41%) and Pit (39.59%) being the common storage types. Storage molds affected 72.2% of respondents, while 28.8% reported wrinkling during storage. Washing was practiced by only 7.6% of farmers. Manual grading was reported by all respondents, with no commercial grading observed. Black sutho production was carried out by 65.2% of farmers. Value addition activities such as sorting were practiced by 65% of respondents, while 25% engaged in transportation and packaging. Respondents' awareness of ginger post-harvest practices varied, with 75.76% having low awareness, 16.66% medium awareness, and 7.58% high awareness. Farmers' general precautions during harvesting, such as avoiding rhizome injury and minimal trimming and sorting, were not accompanied by specific precautionary practices, contributing to their challenges. The findings emphasize the importance of adopting modern post-harvest practices to increase production, improve product quality, and command higher market prices. Implementing these measures will enable ginger farmers in Palpa district to enhance their income and contribute to the growth of the ginger industry in Nepal.

Abstract

Long bean production in East Java has declined in the last three years because of the decreased soil fertility and the failure of pod formation. The addition of organic matter to the soil planting medium and spraying ZPT bean sprout extract are some efforts to increase the supply of nutrients and overcome flower fall. This study aimed to determine the interaction between the treatment of the planting media and ZPT of bean sprout extract toward growth and yield of long bean plants. The study was conducted factorially using a completely randomized design (CRD) in 3 replications. The first factor is the type of planting medium namely M0: soil; M1: soil+ compost; M2: soil+ chaff charcoal; M3: soil+ cocopeat. The second factor was the concentration of ZPT bean sprout extract, namely T0 control; T1: 10%; T2: 20%; T3: 30%. There was a very significant interaction between the treatment of the planting media and the bean sprout extract ZPT on the variable number of pods per plant and wet weight of pods per plant. The best treatment was the combination of the type of soil and compost growing media with ZPT bean sprout extract 20%. The main effect of the type of planting media treatment showed that the results were not significantly different for all observed variables. The ZPT treatment of bean sprout extract significantly affected the variables of flowering age, harvest age, and pod length per plant, the best treatment was the concentration of ZPT bean sprout extract 20%.
