“…The results of this study confirm that bulb biomass of garlic was positively correlated with VWCs while negatively correlated with CWSI (Supplementary Materials Table S1), with both Cp being significant (Table 4). The lower the soil water availability, the lower the bulb biomass, as displayed in previous studies in garlic [37,53,60]. Table 3.…”

Climate change entails increasingly frequent, longer, and more severe droughts, especially in some regions, such as the Mediterranean region. Under these water scarcity conditions, agricultural yields of important crops, such as garlic, are threatened. Finding better adapted cultivars to low water availability environments could help mitigate the negative agricultural and economic impacts of climate change. For this purpose, plant phenotyping protocols based on remote-sensing technologies, such as thermal imaging, can be particularly valuable since they facilitate screening and selection of germplasm in a cost-effective manner, covering a wide range of temporal and spatial scales. In this study, the use of a thermal index known as the crop water stress index (CWSI) was tested as a predictor of bulb biomass and for the assessment of inter-cultivar variability of five garlic cultivars in response to a gradient of soil volumetric water contents (VWCs). Three experimental assays, one in the 2018 season and two in 2019, covering a wide range of water availability levels were carried out. Different linear models were developed, with CWSI and VWCs as continuous predictors of bulb biomass, and the factor cultivar as a categorical predictor. The results support the existence of inter-cultivar variation in terms of sensitivity to water availability. The most productive cultivars under favorable conditions were also the most sensitive to water availability. In contrast, the cultivars with lower bulb production potential displayed lower sensitivity to water availability and higher stability across experimental assays. The results also support that CWSI, which was sensitive to inter-cultivar variability, is a good predictor of garlic bulb biomass. Therefore, CWSI can be a valuable tool for garlic phenotyping and cultivar screening.

“…Reducing the amount of water in this phase affects the quality and quantity of tubers [9]. The influence of the type of fertilizer such as the content of nitrate and the duration of irradiation affect the growth of plants and the condition of the garlic bulbs produced [10]. The maize plant height, leaf area index, above-ground biomass and yield did not significantly decrease due to the decrease in fertilizer application.…”

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.

“…Salah satu penyebab rendahnya produksi dan produktivitas bawang merah di Banten adalah kondisi lahan yang tersedia di Banten merupakan lahan kering. Lahan kering sering diasosiasikan dengan tidak tersedianya air untuk tanaman yang menyebabkan tanaman akan mengalami cekaman kekeringan (Sánchez-Virosta and Sánchez-Gómez, 2019). Cekaman kekeringan pada tanaman akan menyebabkan penurunan hasil (El Balla et al, 2013;Sánchez-Virosta and Sánchez-Gómez, 2019).…”

Aplikasi kalium klorida pada dosis yang berbeda secara fertigasi tetes untuk meningkatkan pertumbuhan dan hasil bawang merahSari Budidaya bawang merah (Allium cepa L.) di Provinsi Banten terhambat oleh masalah kekurangan air karena diusahakan di lahan kering. Oleh karena hal tersebut, kami mengevaluasi pengaruh pemberian kalium klorida (KCl) melalui fertigasi tetes untuk efisiensi penggunaan air dan nutrisi pada budidaya bawang merah di lahan kering Banten. Penelitian polybag dilaksanakan dengan rancangan acak kelompok lengkap (RAKL) dengan 4 ulangan sebagai blok. Perlakuan terdiri dari dosis KCl dengan system fertigasi tetes yakni 50, 75, 100, 125 dan 150% dari dosis rekomendasi KCl untuk Provinsi Banten dan aplikasi KCl dengan sistem irigasi konvensional sesuai dosis rekomendasi sebagai kontrol. Hasil penelitian menunjukkan bahwa tinggi tanaman bervariasi pada berbagai perlakuan pada pengamatan 6 dan 8 minggu setelah tanam (mst). Tinggi tanaman maksimal mencapai 49,4 cm pada perlakuan fertigasi tetes dengan dosis KCl 75% pada umur 6 mst dan 43,5 cm pada umur 8 mst. Jumlah daun pada umur 6 mst juga menunjukkan adanya variasi pada berbagai perlakuan. Jumlah daun terbanyak mencapai 23,1 helai yang ditunjukkan pada perlakuan fertigasi tetes dengan dosis KCl 75%. Namun, pada pengamatan kehijauan daun tidak menunjukkan beda nyata antar perlakuan. Hasil panen menunjukkan bahwa perlakauan fertigasi tetes pada dosis KCl 75% menunjukkan jumlah umbi per tanaman paling banyak (9,3 umbi per tanaman) dan bobot tumbi tertinggi (38,95 gram per tanaman). Dari hal tersebut menunjukkan bahwa aplikasi fertigasi tetes dapat mengurangi 25% dosis rekomendasi KCl dibandingkan dengan sistem konvensional. Kata kunci: Dosis Different potassium chloride doses to increase the growth and yield of shallot under drip fertigationAbstract. Shallot (Allium cepa L.) cropping in the Province of Banten has been impeded by water deficit problem due to it is occupying dry land areas. Therefore, we evaluated the effect of different potassium chloride doses under drip fertigation to increase the growth and yield of shallot in the dry land area of Banten. Potted research was laid out in a Randomized Completely Block Design (RCBD) with four replications as blocks. The treatment consisted of 50, 75, 100, 125, and 150% basal dose recommendation of potassium chloride under a drip fertigation system and 100% basal dose recommendation of potassium chloride under a conventional irrigation system as a control. The result revealed that plant height varied significantly due to the various level of potassium chloride at 6 and 8 weeks after planting (wap). Plant height was maximum at 75% basal dose recommendation of potassium chloride using drip fertigation at 6 wap (49.4 cm) and 8 wap (43.5 cm). In addition, there was significant differences in the number of leaves at 6 wap (23.1 leaves per plant). In contrast, there was no differences in leaf greenness among treatments. At harvest, the number of bulbs was maximum at 75% basal dose recommendation of potassium chlo...
