“…A low temperature is a major inhibitor in garlic bulb growth, which was able to delay their development (Atif et al, 2020). On the other hand, an increased temperature will lead to a high evapotranspiration, which was able to trigger water stress in the crops (Léllis et al, 2021). However, in the study, the correlation coefficient was low value with p value greater than 0.05.…”

Climate change impact in Indonesia is generally characterized by changes in daily temperature, rainfall patterns, and sea level rise. These changes mainly influence agricultural practices for various crops, including garlic (Alium sativum L.). Current knowledge on climate vulnerability related to agricultural impact in Indonesia is limited. This study aims to identify the level of vulnerability of garlic farmer households to climate change and provide recommendations for adaptation activities for garlic farmers. The household vulnerability profile was assessed using Livelihood Vulnerability Index (LVI) and LVI-IPCC approaches. We carried out interviews for 100 respondents in four villages in Lombok to obtain primary data related to agricultural practices. Relation between climate variables and garlic productivity was determined using linear regression approach. The results showed that rainfall and temperature had a negative correlation with garlic productivity as indicated statistical indicators used, namely R2. According to LVI and LVI-IPCC approach, Sembalun Timba Gading and Sajang have the highest level of vulnerability (0.60) and Sajang Village has the lowest level of vulnerability (0.55) among all villages. The findings suggested that climate information should be considered in agricultural sector for climate change mitigation and adaptation.

“…This is a semi-arid climate region, where the average annual temperature is around 14 • C, and the accumulated rainfall is between 200 and 400 mm year −1 (recorded mainly in spring and autumn). The average annual reference evapotranspiration is around 1300 mm year −1 , varying between 30 and 220 mm month −1 in January and July [19]. In general, in CLM, the average soil depth is between 40 and 60 cm, finding a petrocalcic horizon.…”

“…The main advantage of MOPECO is that it generates irrigation schedules according to the total available irrigation water in a user-friendly way, while considering complex concepts [13][14][15]. The farmers only need to insert the data from their farms and select their crops from a list of calibrated crops, mainly for the Castilla La Mancha region (CLM-Spain) (maize [13,16], onion [17], garlic [18,19], barley [20,21], potato [22], melon [23]), but also for other countries [23,24].…”

“…Together with barley, it is an essential crop within the typical agricultural systems in the area. Additionally, garlic, with more than 28 million of Mg produced annually in the world, is ranked 14th in areas dedicated to vegetable crops [19]. In Spain, Castilla-La Mancha (CLM) is the largest producing region (60% of the national total production [28]), with this sector being of great economic and social significance.…”

Improving the Sustainability and Profitability of Oat and Garlic Crops in a Mediterranean Agro-Ecosystem under Water-Scarce Conditions

et al. 2022

In areas with scarce water resources, population growth and climate change scenarios will mean that there is increasingly less water available for agricultural activity. Thus, optimizing crop irrigation water management is an absolute necessity. To address this situation, the SUPROMED project (sustainable production in water-limited environments of Mediterranean agro-ecosystems), available in an online platform, brings together a series of models and methodologies designed to promote more efficient management of water, energy and fertilizers. A two-year trial (2020–2021) was implemented in the Castilla-La Mancha region (Spain), with the aim of showing the effectiveness of SUPROMED as a farm management support tool. The trial was conducted on two of the region’s most important crops (oats and garlic). A series of productive, economic, and environmental key performance indicators (KPIs) were analyzed to measure the impact of transferring MOPECO (model for the economic optimization of irrigation water use at farm level), the irrigation scheduling model integrated in the SUPROMED platform, to farmers. In 2020, the management plan proposed by SUPROMED achieved a higher yield for oat than that generated by traditional management, using 40% less water. In the case of garlic, the same yield was obtained, using 30% less water. Gross margin and gross economic irrigation water productivity were improved for both crops. In 2021, one of the selected farmers was trained to use the SUPROMED platform to work with garlic crop. This management improved most of the KPIs analyzed compared to previous management without the SUPROMED platform, obtaining similar results to those obtained by SUPROMED in 2020. The results demonstrate that the tools and models included in SUPROMED have been properly adapted and can be easily used by farmers, improving the economic and environmental sustainability of Mediterranean agroecosystems.

“…The cultivation of garlic can positively contribute to the local economy of rural areas, but needs tools to help in decision making for more efficient use of water (3). Adaptation of plants to environmental conditions is very important to produce crops under conditions of sustainable climate change.…”

Quality of Garlic Bulbs with Irrigation Application according to Plant Needs

et al. 2022

View full text Add to dashboard Cite

The irrigation technique that has been done by farmers so far has not been optimal in increasing garlic production. This study aims to evaluate the quality of garlic tubers with irrigation applications according to plant needs. The experiment was carried out in Lembang, West Java, in 2020. The method used in this study was a group design of 6 treatments with four replications. Treatment A (daily ET accumulation within two days), B (daily ET accumulation within three days), C (daily ET accumulation within four days), D (daily ET accumulation within five days), E (daily ET accumulation within six days), F (farmers' irrigation practices). The plant data obtained were analyzed using Analysis of Variance (ANOVA) at the 5% level. Data analysis was performed using the PKBT - STAT 1.01 program. The results showed that the tuber diameter in treatment B (daily ET accumulation within three days) was significantly greater than control. Weight, weight loss, and water content were not significantly different between all treatments. The volatile content in all treatments was significantly higher than control.
