The research aim to determine the effect of the use of phytohormone extracts of red onion (Allium cepa), stem cuttings material and the interaction of phytohormone extracts of A. cepa with stem cuttings material on the growth of mulberry (Morus multicaulis) plants. This research was conducted at the Research and Development Institute of Tanjungpura University from March to May 2019. The method of research was an experimental method with a Split Plot Design. The treatments consisted of the stem cutting materials (base, middle and shoot) as the main plot and the dose of shallots extract (0 g/l, 500 g/l and 1000 g/l) as subplots. Each treatment consisted of three groups, so that the total of treatments were 27 plots. The results showed that only the dose of shallots extract which significant influented on the M. multicaulis  growth. Whereas the stem cutting materials and interactionsof both were did not effect significantly. The highest of murbei growth was obtained at 1000 g/l of shallot extract on 6,52% of the leaves number, 500 g/l of branch length 4,52% and 3.88% of the roots number. Thus, the extract of A. cepa L can be used as an alternative for plant growth, especially M. multultulis plants.Keywords: Mulberry, stem cuttings, phytohormone.

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.

Onions (Allium cepa L.) is one of the leading horticultural commodities in Indonesia and is often used as seasoning and traditional medicine. Onion has a high economic value and fluctuating prices so that domestic onion production needs to be improved, one of them with a presence of endophytic bacteria that act as plant growth promoting agent or Plant Growth Promoting Bacteria (PGPB). Endophytic bacteria isolated from the root, leaves, and bulbs. In this research has been tested endophytic bacteria of onion plants from Garut regency which has PGPB factors such as able to dissolve phosphate, and produce HCN. The results obtained 251 isolates of endophytic bacteria. Based on the characterization results, the superior isolates capable of dissolving phosphate with an average diameter of 0.45 cm is isolate II.B.1D.3, and 11 isolates capable of producing high HCN. These isolates can be used as PGPB agents so that they can be useful in increasing plant growth and onion production and biocontrol in suppressing pathogens. Keywords: PGPB, endophyte, onion, phosphate, HCN

<p>True shallot seed (<em>Allium cepa var Aggregatum group</em>) is an alternative way of growing shallot. Different environments and cultivars need a specific study. The aim of this research was to find out the best technology to grow Trisula true shallot seed by managing plant densities and applying compost and biofertilizer in alluvial soils. The study was performed from May to October 2015, using a split-plot design with four replications. The main plot was plant density: 100 plants m-2 and 70 plants m-2. Subplots were five fertilizer application combinations, they were 100% recommended dose of NPK (R-NPK), 100% R-NPK + compost, 100% R-NPK + compost + biofertilizer, 50% R-NPK + compost and 50% R-NPK + compost + biofertilizer. Results showed that biomass and bulb yield were significantly affected by plant density and fertilizer application. The reduced 50% R-NPK by substituting with compost and biofertilizer was unable to maintain shallot bulb yield equal to 100% R-NPK, suggesting insufficient nutrients derived from compost to satisfy the shallot requirement. The best technology to grow true shallot seed of Trisula variety was 100 plants m-2 plant density and 100% NPK (consisting of 180 kg N ha-1, 52 kg P ha-1 and 50 kg K ha-1) with 2.5 t ha-1 compost that achieved the highest bulb yield of 9.83 t ha-1 and increased the revenue.</p>

Effects of crop arrangement and cutting on the silages quality of two varieties of maize (Zea mays L.)ABSTRACT. The objective of this experiment was to study the interaction effect of varieties, spacing and cutting on the quality of silage as foodstuff. The experiment had been conducted from January to April, 2007 at the experimental Garden of Faculty of Agriculture, University of Haluoleo. This experiment was arranged in Split-Split plot design with three factors. The first factor was variety as main plot, consisting of BISI-2 variety and local variety; the second factor was space arrangement as sub plot, consisting of 60 cm x 40 cm (J1), 75 cm x 40 cm (J2), 90 cm x 40 cm (J3), the third factor was cutting period as sub plot, consisting of no cutting (Po), cutting on 40 days (P1), and cutting on 55 days (P2). So that there were 2 x 3 x 3 x 3 = 54 experimental units. Analysis of variance was applied to know the effect of treatment. If so, least significant difference (LSD) 0.05 (95 %) confidence level was used. Variables observed was plant growth determining silages quality, consisting of quality of crude protein, crude fiber, crude fat, and water. Results of research revealed that interaction affect of spacing and cutting periods on 40 days of BISI-2 variety gave the best yield of plant growth for plant height. While the local variety tended to adverse effect of cutting. However, the quality of silages of two varieties tended to be similar. Every crop spacing had a positive effect of cutting on 40 days. The best quality of silages of two varieties was resulted from the interaction between spacing 75 cm x 40 cm and cutting of 40 days.

Pruning coffee plants is intended to stimulate generative growth that increases productivity to reach optimal. Plant Growth Regulator (PGR) makes it possible to exploit the production potential of plants. Pruning management, combined with the PGR in coffee plants, is expected to improve flowering and berry growth. The research was conducted for 7 mo from October 2017 to April 2018 at Gunung Gede, Bogor, West Java, Indonesia. A split–plot design with two treatment factors was used in this research. Pruning was placed as the main plot consisting of two levels, namely without (P0) and with pruning (P1). The PGR application was placed as a subplot, consisting of three dosages, namely without PGR (Z0), and concentrations of 0.3 mL L–1 (Z1) and 0.4 mL L–1 (Z2). The results showed, the pruning treatment significantly influenced microclimate, number of branches, B0, B1 and B2, number of berry sets, and berries. Pruning treatment had a very significant effect on microclimate, plant height, number of branches, number of coffee fruits, yields crops–1, and productivity. Interaction both significantly affected plant height and B0. The best dosage had not yet been found.
