Growth and yield of shallots (Allium cepa var aggregatum L.) under different seed bulbs storage period

The availability of qualified and sustainable seeds is one of the determinants of the success of shallot farming. One of the constraints factor in the supply of shallot seeds is the short storage period that is about 2-3 months. This study aims to determine the effect of varieties and seed storage period on growth and yield shallots. This research was conducted at Indonesian Vegetables Research Institute, Lembang, West Java, Indonesia. The study was designed using split plot design with four replications. The main plot was seed storage period for four months, five months and six months after harvest and the subplot was varieties, consisting of seven varieties that have been released, namely Bima Brebes, Katumi, Kuning, Pikatan, Trisula, Pancasona and Mentes. The results showed that the yield of wet bulbs per hectare of five-months-storage period bulb seeds was significantly higher than six months storage period for the varieties of Bima Brebes, Katumi, Kuning, Pikatan, Pancasona and Mentes. Five-months-storage period of shallot bulb seeds can still be used as a source of seeds for the varieties of Bima Brebes, Katumi, Kuning, Pikatan, Pancasona and Mentes.

Hasil penelitian menunjukkan bahwa perlakuan sistem penanaman berpengaruh nyata terhadap hasil paprika. Rata-rata hasil total dan hasil kelas buah >200 g yang ditanam dengan sistem penanaman satu tanaman per polibag berturut-turut lebih tinggi 14,1% dan 17,0% daripada tanaman yang ditanam dengan sistem penanaman dua tanaman per polibag. Perlakuan sistem pemangkasan tunas hanya berpengaruh nyata terhadap hasil kelas buah >200 g dan sistem pemangkasan sisa tiga daun memberikan hasil kelas buah >200 g lebih tinggi daripada sistem pemangkasan sisa dua daun. Hasil total, hasil kelas buah >200 g dan kelas buah 100–200 g varietas Spider lebih tinggi dan berbeda nyata dibandingkan dengan varietas Inspiration. Hasil penelitian merekomendasikan bahwa tanaman paprika sebaiknya ditanam dengan sistem satu tanaman per polibag dan sistem pemangkasan sisa tiga daun. Bila buah paprika yang diinginkan relatif besar maka varietas Inspiration yang ditanam, sedangkan bila buah dengan ukuran sedang maka varietas Spider yang ditanam.KeywordsCapsicum annuum var. Grossum; Hasil; Sistem penanaman; Sistem pemangkasan; Varietas AbstractYields of sweet peppers depend on planting system and shoot pruning system. A research with the aim to optimize planting system and shoot pruning system in two sweet pepper varieties has been carried out in the Experimental Field of the Indonesian Vegetable Research Institute in Lembang (1,250 m asl.), West Java from May 2011 until February 2012. Three treatment factors consisted of planting system (one plant and two plants planted per polybag), shoot pruning system (pruning with two leaves and three leaves remaining per node) and variety (Inspiration and Spider) were laid-out using split plot design with three replication. The results indicated that planting system treatment significantly affected the yields of sweet pepper. Average total yields and yields of fruit >200 g from plants using one plant per polybag were 14.1% and 17.0% higher than those of plants using two plants per polybag. The shoot pruning treatment significantly affected only on the yields of fruit >200 g and the shoot pruning system with three leaves remaining per node gave significantly higher yields of fruit >200 g compared to the shoot pruning system with two leaves remaining per node. The total yields, yields of fruit >200 g and yields of fruit 100–200 g of Spider were significantly higher than those of Inspiration with the average total yields of Spider 12.3% higher than Inspiration. The results suggest that sweet pepper should be planted using one plant per polybag and the shoot pruning with three leaves remaining per node. If desired the relatively big size fruit, Inspiration is recommended, however, if desired the medium-size fruit, Spider is recommended.

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G- 2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (4) 50 cm were used in the experiment in a split-plot design with row spacing in the main plot and cultivars in the sub-plot. Seeds were sown on 26 July 2005 at specified rows maintaining 5 cm plant to plant distance. The highest seed yield was obtained from 20 cm spacing and yield decreased with increased spacing irrespective of cultivars. Among cultivars the highest yield was given by cultivar BS-5 which was followed by PB-1. It was concluded that the soybean cultivars BS-5 and PB-1 could be selected for sowing in Kharif-II season and should be planted at 20 cm apart rows for achieving higher yield.

Perbanyakan karet (Hevea brasiliensis Muell. Agr.) dengan okulasi cokelat membutuhkan waktu yang lama dalam pembibitannya, sedangkan perbanyakan dengan okulasi hijau belum banyak dilakukan karena tingkat keberhasilan masih sangat rendah. Salah satu faktor yang diduga berpengaruh terhadap keberhasilan okulasi hijau adalah umur bibit batang bawah. Tujuan penelitian adalah mengetahui pengaruh perbedaan umur batang bawah terhadap persentase keberhasilan okulasi hijau pada tiga klon karet. Penelitian dilaksanakan di Kebun Percobaan (KP.) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar pada bulan Januari-Desember 2013. Penelitian menggunakan rancangan petak terbagi, tiga ulangan dan ukuran petak 25 pohon. Petak utama adalah jenis klon batang bawah, terdiri dari 3 klon, yaitu K1 = AVROS 2037, K2 = PB 260, dan K3 = GT 1. Anak petak adalah umur batang bawah terdiri dari 4 taraf, yaitu U1 = 4 bulan, U2 = 5 bulan, U3 = 6 bulan, U4 = 7 bulan. Okulasi dilakukan dengan cara membuka kulit batang bawah, kemudian entres dimasukkan ke dalam jendela sayatan hasil pembukaan. Pengikatan sambungan dilakukan dengan menggunakan plastik khusus dengan cara dililitkan dari bawah ke atas. Pengamatan dilakukan terhadap persentase keberhasilan okulasi hijau pada umur tiga minggu setelah okulasi (MSO). Hasil penelitian menunjukkan bahwa keberhasilan okulasi hijau pada tanaman karet dipengaruhi oleh umur batang bawah. Untuk Klon PB 260 dan GT 1, makin tua umur batang bawah sampai maksimum 7 bulan di polybag maka semakin meningkat persentase keberhasilan okulasi, sedangkan pada klon AVROS 2037 belum memperlihatkan perbedaan yang nyata.Kata kunci: Hevea brasiliensis, umur batang bawah, klon, keberhasilan okulasi hijauPropagation of rubber (Hevea brasiliensis Muell. Agr.) using brown budding need a long time in the nursery, whereas the propagation usinggreen Budding has not yet been done due to the success rate is still very low. One of the factorthat might influence the successfulness of green budding is rootstock age.. The purpose of this study was to determine the effect of different age of rootstock on the percentage of green budding success in three rubber clones. The experiment was conducted at the Pakuwon experimental station (ES), Indonesian Industrial and Beverage Crops Research Institute, from January-December 2013. The research was done using split plot design with three replications, and the plot size is 25 trees. The main plot was the type of clones used for rootstock that comprised of 3 clones: K1 = AVROS 2037, K2 = PB 260, and K3 = GT 1. Meanwhile, the subplots were rootstock age consists of 4 levels, namely: U1 = 4 months, U2 = 5 months, U3 = 6 months, U4 = 7 months. Observations were made on the percentage of green budding success at 3 weeks old after grafting . The results showed that the success of the green budding on the rubber plants is influenced by the age of rootstock. The use of rootstock up to 7 months old in polybag in PB 260 dan GT 1 clones would increase the percentage of grafting success, whereas AVROS 2037 clone did not show any significant different.
