“…Altered agroclimatic conditions led to the prolonging dry season in certain areas, and afterward, drought stress incidence emerged to endanger the cultivated plant. Several intensification strategies that used to prevent environmental effects such as fertilizer and shading (Suradinata et al 2019a;Nafi'ah et al 2021). Another intensification strategy used to eliminate the negative effect of drought stress on plants is the application of a plant growth regulator (PGR).…”

Abstract. Mubarok S, Wicaksono FY, Nuraini A, Rahmat BPN, Budiarto R. 2022.S hort Communication: Agronomical characteristics of sweet corn under different plant growth regulators during the dry season. Biodiversitas 23: 3091-3098. Sweet corn (Zea mays convar. saccharata var. rugosa)is one of the important horticultural crops. Increasing sweet corn production during the dry season can be achieved by applying plant growth regulators (PGR). PGRs such as auxin, gibberellin, cytokinin, ethylene, and other phytohormones control various physiological and chemical processes in plants. The PGR is often used for the engineering process of plant cultivation technology, especially during environmental stress conditions. This study aimed to determine the effect of PGRs (auxin, gibberellic acid, salicylic acid, and paclobutrazol) on sweet corn growth and yield during the dry season. The results showed that the application of PGR significantly affected sweet corn growth, yield, and yield quality during the dry season. The auxin significantly increased plant height and leaf length, whereas paclobutrazol and salicylic acid significantly increased the number of cobs and total soluble solids of sweet corn, respectively.

Sweet potato is an important agricultural commodity in Indonesia and it is the source of carbohydrates after rice. However, the quality and quantity of sweet potatoes produced decreased and did not fulfill the demand. Provision of growth regulators is one of the efforts to increase the growth of sweet potatoes, shallot extract is one of the natural growth regulators that can be used. This study aims to determine the interaction between the concentration of shallot extract and the duration of immersion on sweet potato cuttings. This research was conducted in Garut from February to June 2021. This study used an experimental method with a Randomized Block Design 3x3 factorial pattern with 3 replications. The first factor is the concentration of shallot extract (K), namely k1 (30% shallot extract concentration), k2 (60% shallot extract concentration), and k3 (90% shallot extract concentration). The second factor is the soaking duration (P), namely, p1 (soaking duration 30 minutes), p2 (soaking duration 60 minutes), and p3 (soaking duration 90 minutes). The experimental results showed that there was an interaction between the concentration of shallot extract and the soaking duration of sweet potato (Ipomoea batatas L.) cuttings on leaf area, tuber weight, and tuber length, the best concentrations being k1 (30% concentration) and p3 (soaking duration 90 minutes).

“…is one of the most widely adapted food crops in the world. It is widely grown by farmers in rural areas or cultivated as a commercial crop (Loebenstein and Thottappilly 2009;Nafi'ah et al 2021). Besides issues of yield stability and non-uniformity of tuber size, sweet potato production is also facing postharvest challenges including, skinning injury.…”

Abstract. Dewayani, Maulana H, Wicaksana N, Suganda T, Concibido V, Karuniawan A. 2021. Distribution and prevalence of scurf (Monilochaetes infuscans) on sweet potato (Ipomea batatas) in West Java, Indonesia. Biodiversitas 22: 2876-2883. Scurf (Monilochaetes infuscans) is a common sweet potato (Ipomoea batatas (L.) Lam.) tuber skin discoloration disease, that can cause significant yield loss, especially when tubers are destined for the export market. Despite the economic importance of the disease in West Java, Indonesia, there is a dearth of information on the distribution and severity of scurf disease. To address this gap, a disease survey was carried out across 28 fields in six districts (Bandung, Sumedang, Garut, Kuningan, Cianjur, and Bogor) of West Java from 2016 to 2018. Scurf disease prevalence was recorded by counting the number of infected tubers from 15 plant samples per field. Disease incidence was recorded when at least one infected tuber per plant was observed. Severity of scurf diseases was estimated by measuring the percentage of infected surface area, using AutoCAD map 2019. Results show that scurf was distributed across all locations surveyed. Disease incidence ranged from 1.68% (Cikadu) to 27.56% (Cilembu) while disease severity ranged from 7.92% (Cikadu) to 57.00% (Cilembu). Based on potato dextrose agar (PDA) culture plates, 68.57 % of tubers were infected with various fungi. Among them, M. infuscans (32.14 %) was the most prevalent and most widely distributed pathogen associated with the scurf disease across sweet potato fields in West Java, Indonesia. To effectively manage the disease and improve farmers’ income, it is imperative to establish effective and sound integrated disease mitigation strategies based on the results of this survey.
