Abstract

Elaeisponic is new introducing growing technique to produce vegetables by planting it in the frond based of oil palm trees (Elaeis guineensis Jacq.). However, there was no previous report on vegetable production by using elaeisponic production system, including the use of foliar fertilizers. This study aimed to determine the optimum consentrations and frequency of foliar fertilization for caisim grown in elaesisponic production system. An experiment was conducted in oil palm plantation area by using a factorial randomized complete block design with three replicates. The first factor of treatment consisted of three levels of foliar fertilizer concentration, 1 g l-1, 2 g l-1 and 3 g l-1, and the second factor was application frequency of foliar fertilizer, 7 days after transplanting (DAT), 7, 14 DAT and 7, 14, 21 DAT. Crop responses were determined on leaf greenness (SPAD index), shoot fresh weight (g), root fresh weight (g), leaf area (cm2) and plant dry weight.  Results indicated that both concentration of foliar fertilizer and frequency of application as wells as its interaction did not significatly affect leaf greenness, leaf area, shoot fresh weight, root fresh weight and plant dry weight of caisim plants.  Further research should be addressed on optimizing the use of palm oil frond bases as growing medium for vegetable production.  Keywords: Elaeisponic Production System; Brassica juncea L; Foliar Fertilizer; Frequency of Application.

Abstract

biodegradable polymer such as PVA is considered the most promising candidates for developing the sustainable sticker. The objective of this study was to determine the most suitable PVA + TS blends as adhesives agent for AMF spores inoculation via seed coating which can enhance the spores viability and their beneficial properties in maize. The polythene bag experiment was performed in a screen house of the Department of Plant Protection Faculty of Agriculture, University of Bengkulu Indonesia in 2015. Six adhesive blends were employed: 100% PVA + 0% TS, 75% PVA + 25% TS, 50% PVA + 50% TS, 25% PVA + 75% TS, 0% PVA + 100% TS, and no coating. The six experimental treatments were laid out in a completely randomized design with three replications. The results show that root colonization, AMF spore population, and shoot dry weight in 75% PVA + 25% TS were equal to those in 100% PVA. Root colonization, AMF spore population, shoot P content, and shoot P concentration were greater for 50% PVA + 50% TS than 100% PVA, 100% TS, and no coating. A mixture of 50% PVA + 50% TS was considered the preferred sticker. Thus, the tapioca starch can be used to substitute 25 - 50% of the PVA used without reducing AMF inoculant adhering to seed.Keywords: polymeric seed coating, seed coating formulation, arbuscular mycorrhizal fungi, sustainable coating adhesive, seed inoculation, seed inoculant

Abstract

The development of citrus crops is directed to produce tangerine plants that lead to substitute imported fruits by the development of budding seedlings technique using local varieties citrus.  This research was conducted in November 2016 until March 2017 in citrus nursery of Horticultural Seed Center of Pematang Donok Village, Kabawetan Sub-district, Kepahiang Regency, Bengkulu Province.  The research was arranged in a Completely Random Design with combination of two treatments, the first treatment was the origin of bud on the scion plant, they were E1 (upper part of the shoot scion), E2 (middle part of the shoot scion), E3 (basal of the shoot scion).  The second treatment was cut type on the rootstock, they were J1 (H type), J2 (Forkert slice), J3 (T wedge).  The treatment was repeated three times, so there were 27 experimental units.  Each experimental unit consisted of 10 liners, so there were 270 liners of the experiment.  The result of this research showed that incision types of H model and Forkert model, as well as the bud originated from the middle and the basal part of shoot scion were good to support the success rate of budding propagation of Rimau Gerga Lebong (RGL) tangerine.
