Professional peat-free substrates for ornamental plant production are increasingly required by nursery growers. Most promising materials are green compost, coconut coir dust, and woody fibre, used alone or in mixtures. One of the major concerns is pH, usually higher than optimal. In this work, a method based on a three-step procedure was adopted to acidify three organic matrices alone or in mixtures and to individuate the most suitable product, between iron(II) sulphate 7-hydrate and elemental sulphur chips. Firstly, the determination of the buffering capacity by dilution with sulphuric acid was carried out to determine dosages. Afterwards, an incubation trial of 84 (iron(II) sulphate) or 120 days (sulphur chips) was conducted on matrices and substrate mixtures with calculated doses in a climatic chamber maintained at 21 °C. Iron(II) sulphate resulted not suitable because it caused a rapid, but not lasting, pH lowering and an excessive electrical conductivity (EC) increase. Sulphur chips could instead guarantee an adequate and lasting pH lowering. These results were then validated in the open field trial on matrices and substrates. The proposed acidification methodology could be considered in developing new substrates, but the rapidity of pH acidification and EC increase on plant and mineral nutrition should be further investigated.

The work summarizes the prospective conceptions of all the five horticultural branches. These branches (vegetable, fruit, grape and wine, herb and ornamental plant production) with the production of propagating material together amount to round 30-35% of the total value of the entire plant production. The performance of horticultural branches declined significantly because of privatisation and lack of capital. The accession to the EU urges the development of modernization and competitiveness, therefore the state subsidies are indispensable.

AbstrakPenelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang dapat mempengaruhi jumlah produksi tanaman hias Dracaena dan menganalisis tingkat efisiensi alokatif penggunaan faktor produksi usahatani tanaman hias Dracaena di Kabupaten Sukabumi. Penelitian ini dilakukan di Kabupaten Sukabumi sebagai sentra tanaman hias Dracaena terbesar di Provinsi Jawa Barat pada bulan Januari sampai Juni 2018. Penelitian dilakukan dengan metode survey dengan pengambilan sampel secara simple random sampling. Penelitian dilakukan terhadap 35 orang petani tanaman hias Dracaena di Kabupaten Sukabumi dengan tujuan pasar ekspor. Data yang dikumpulkan dianalisis dengan menggunakan analisis faktor-faktor yang berpengaruh terhadap jumlah produksi tanaman hias Dracaena menggunakan analisis fungsi produksi dan analisis efisiensi penggunaan faktor-faktor produksi usahatani. Hasil penelitian menunjukkan bahwa faktor produksi yang berpengaruh signifikan terhadap jumlah produksi tanaman hias Dracaena di Kabupaten Sukabumi adalah luas lahan, benih, dan tenaga kerja dimana kenaikan atau penurunan penggunaan ketiga faktor produksi tersebut akan mengakibatkan kenaikan atau penurunan jumlah produksi Dracaena. Pengalokasian faktor produksi luas lahan, benih, pestisida, dan tenaga kerja pada usahatani tanaman hias Dracaena di Kabupaten Sukabumi belum efisien sehingga penggunaannya perlu ditambahkan untuk mencapai efisien, sedangkan penggunaan faktor produksi pupuk pada usahatani tanaman hias Dracaena tidak efisien sehingga penggunaannya perlu dikurangi.Kata Kunci: efisiensi alokatif, faktor produksi usahatani, tanaman hias DracaenaAbstractThis study aims to identify the factors that can affect the amount of Dracaena ornamental plant production and analyze the level of allocative efficiency of the use of Dracaena ornamental plant farming production factors in Sukabumi Regency. This research was conducted in Sukabumi Regency as the largest Dracaena ornamental plant center in West Java Province in January to June 2018. The research was conducted by survey method by sampling using simple random sampling. The study was conducted on 35 Dracaena ornamental plant farmers in Sukabumi Regency with the aim of the export market. The data collected was analyzed using the analysis of factors that influence the amount of ornamental plant production Dracaena used an analysis of production functions and an analysis of the efficiency of the use of farm production factors. The results showed that the factors of production that had a significant effect on the amount of production of Dracaena ornamental plants in Sukabumi Regency were land area, seeds, and labor where the increase or decrease in the use of the three production factors would result in an increase or decrease in the amount of Dracaena production. Allocation of production factors for land area, seeds, pesticides, and labor in Dracaena ornamental plant farming in Sukabumi Regency has not been efficient so that their use needs to be added to achieve efficiency, while the use of fertilizer production factors in Dracaena ornamental plant farming is inefficient so their use needs to be reduced.Keywords: allocative efficiency, farming production factors, Dracaena ornamental plants

The nursery industry in Florida relies entirely on peat as a major component in potting soil. Escalating peat costs are a major concern, so alternative media are attractive in Florida. The objectives of the project were to study the feasibility of using food waste compost (FWC) to replace peat in different annual ornamental crops. The experiments were conducted in Spring 2004 at the University of Florida/SWFREC Immokalee, Fla. The crops basil (Ocimum basilicum L.), marigold (Calendulaofficinalis L.), and periwinkle (Vincarosea L.) were grown in mixes of FWC. The treatments were: 1) 100% FWC; 2) 60% FWC, 25% vermiculite, 15% perlite; 3) 30% FWC, 30% peat, 25% vermiculite, 15% perlite; and 4) 0% FWC, 60% peat, 25% vermiculite, 15% perlite, by volume. Basil `U.H' was direct seeded; marigold and periwinkle were transplanted (5 cm tall) in pots (2 inches). All treatments received 4 g per pot of Osmocote (19-6-12) for 4 months. Percentage of basil germination and biomass were higher in mixes with 60% and 30% FWC as compared with 100% FWC and the control. Lower basil biomass in the control media was due to high weed biomass grown in the peat control media. There were no differences in biomass and number of flowers per plant among marigold treatments. But, periwinkle dry biomass and number of flowers per plant were higher in the control and 30% FWC than in 60% and 100% FWC, indicating a negative effect of FWC in periwinkle. It can be concluded that FWC may become a viable alternative to replace peat in basil and marigold when included in potting mixes between 30% and 60% by volume, but a negative effect was reported in periwinkle production.

New Pest

Monitoring of pest species in plant production and extended trade on ornamental plant material, including precise identification, are the main goals of modern plant protection. As a result, a new species of phytophagous thrips – <I>Hercinothrips femoralis</I> (Reuter, 1891) was recorded in Slovakia (experimental greenhouse in Comenius University, Bratislava) in mid 2007. Some plant specimens infested by this pest showed signs of lesions especially on young leaves. The species has been reported in more European countries recently. Due to the potential damage it can cause, increased attention should be paid to pest monitoring.
