Abstract

ABSTRACTVegetables are important agricultural commodities. Productivity of vegetables in Indonesia is still low. One effort that can be done is an application of specific fertilizer recommendations. Fertilizer recommendation based on soil analysis is still rarely for vegetable crops and need further development. The purpose of this paper is to describe some fertilizer recommendations based on soil analysis for vegetable crops. Three stages to consider in the assessment of the research such as soil incubation, correlation test, calibration test and fertilizer recommendation statue. Application all this stages of soil method recommendation in Indonesia is still not widely applied. Two researches which were completed until the entire stage has been done for yard long beans and tomatoes. Recommendations for tomatoes on Inceptisols soil type with very low nutrient status of soil K was 180 kg K2O ha- 1, a low K soil nutrient status was 131.4 kg K2O ha-1, soil K nutrient status was 82.2 kg K 2O ha-1. Yard long bean that planted on Ultisol soil type with low soil P nutrient status was recommended by an application of 185.8 kg P2O5 ha-1, medium soil P nutrient status was added 174.9 kg P2O5 ha-1. Development of fertilizer recommendation based on soil testing to support agricultural development in Indonesia still has some problems and need some strategies for further research, application and dissemination in the future.Key words: vegetables, soil test, fertilizer recommendation

Abstract

The agricultural problems currently cover-up with limited land, water, infrastructure, production facilities and infrastructure, access to finance and institutions. These problems cause the quantity and quality of agricultural products to be stumpy. One effort that can eliminate these problems is through the assessment of a comprehensive, integrated agricultural development program.  The objectives of this study was: (1) to determine the amount of citrus farming income, and (2) to analyze the economic and institutional feasibility of citrus farming in Bunga Tanjung Village, Betara District, west Tanjung Jabung region. This study was conducted in Bunga Tanjung Village, Betara District, West Tanjung Jabung, Jambi, from 2017-2019. Approach to the activities through coordination and program integration from the Regional Government. Efforts to increase the production of citrus plants are currently experiencing challenges due to doubtful economic viability. Data collected in this study includes primary data in the form of information from farmers and secondary data such as a profile of study area, demographics, social and economic potential data. Primary data was collected by interviewed farmers using a questionnaire. The sample was randomly determined citrus farmer population with 40 respondents. Data analysis techniques include tabulation analysis used to recognize the farmer's economic conditions and feasibility. The results of this study indicated that citrus productivity had increased continuously by applying environmentally friendly cultivation technology i.g. Fertilizing, controlling pests and diseases, removing water shoots, pruning shapes, and pruning unproductive branches. Citrus production of non-demonstration plots was 3.145 kg, and demonstration was 4.960 kg, there was an increase of 1.815 kg or 36.59% with an average of R/C ratio for demonstration plots was 2.51 while non-demonstration citrus of 2.20. This means that the cultivation of the citrus plant is feasible to continue.

Abstract

Cinnamon is one of leading plantation commodity in Jambi Province, especially in Kerinci Regency, and has an enormous portion as the country's revenue. In addition, cinnamon is a multi-functional plant that can be used in industry, besides functioning as land conservation. However, seed support and technology studies need to be more considered and implemented. The purpose of this paper was to describe the seeds and cultivation innovation technology for cinnamon in Jambi Province. The study was carried out in several sub-districts in Karinci in 2018, using selected mother trees, demonstration plot for harvest and post-harvest analysis. The results show that recently the need for cinnamon seeds still has not sufficient. However, more than 4.000 cinnamon seeds have been distributed and provided with technology assistance for local Kerinci farmers. Dissemination of institutional cinnamon production guidelines and certification of cinnamon seedlings has been carried out in several farmers. The package of cinnamon technology components has been studied and disseminated within this Kerinci areas.

Abstract

General characteristics of fresh horticultural products like chili, is easily get damaged after harvest. The chili declining quality and loss after harvesting occur due to ongoing respiration process. Hence, the chilies become wither or rot. This damage happens due to physical, microbiological, and physiological influences. Physical damage and yield loss can be caused by packaging uses during storage. The study aimed to determine the effect of packaging use type for Locker Telun Berasap chillies on the weight loss and damage during storage. The treatments were the commonly community packaging use types which consists of: a) polyethylene plastic (PE), b) paper and c) banana leaf. Each treatment was performed two replications and stored at room temperature. Observation parameters during storage were weight loss, and physical, physiological, microbiological damages. The lowest weight loss percentage for 12 days’ storage by PE packaging was 45.5%. The total damage was 30% lower compared to paper and banana leaf packaging. Optimal freshness can be achieved until the 8th day of storage with physical damage only 1.03% on PE packaging. The results of the study showed that the dominant microbiological damage was found in the banana leaf packaging treatment.

Abstract

Agriculture is one of the most vulnerable sectors to climate change, which can significantly impact national food security. In addition to climate change, agricultural development faces challenges, including the conversion of agricultural land for non-agricultural purposes. As a result, agricultural extensification has expanded into marginal lands, such as tidal swamplands. This paper presents a literature review on the characteristics of tidal swamplands, the principles of the surjan system, and its relevance in addressing climate change, particularly in the context of food security and ecosystem sustainability. Various literature sources were analyzed to assess the advantages, challenges, and sustainable management strategies of tidal swamplands. The review highlights the importance of effective land management to create suitable soil conditions for optimal plant growth and increased productivity. The surjan system, a land management approach practiced by tidal swampland farmers, demonstrates high adaptability in mitigating the impacts of climate change. This system integrates cultural, ecological, and economic perspectives by combining local knowledge with technological advancements. Key components of the surjan system include a one-way water management system with flap-gates and stoplogs, as well as the use of climate-adaptive crop varieties on tidal swamplands.
