Abstract

Borneo Prima Mandarin (Citrus reticulata cv Borneo Prima) is a new local commodity that grown in lowland but has an interesting orange skin. As a new commodity, Borneo Prima Mandarin has to be developed in order to reduce citrus import. The research was conducted in lowland area (250 m above sea level) IPB research station, Sindang Barang, Bogor from February 2014 to February 2015. The aim of this research was to observe the effect of phosphorus and potassium (PK) fertilizer and pruning on the growth and performance of the plants. This research used Randomize Complete Block Design (RCBD) with two factors. The first factor was aplication of PK fertilizer (15 g P+ 10 g K, 15 g P+ 15 g K, 20 g P+10 g K, 20 g P+15 g K per plant) and the second factor was pruning form (without pruning, open center pruning and hedge pruning). The result showed that the combination of phosporus and potassium fertilizer just gave a significant effect to number of shoot. The highest number of new shoots formed by fertilizing 15 g P+10 g K per tree per application. Pruning treatments had significant effect to plant architecture (i.e reduce plant height, land occupation). Open center pruning and hedge pruning made the crown more open that can increase the light interception so that increase the rate of photosynthesis.

Abstract

Benih kedelai memiliki daya simpan yang rendah karena penurunan kualitas benih selama penyimpanan berlangsung lebih cepat dibandingkan benih tanaman lain. Kedelai setelah dipanen akan mengalami penurunan benih baik secara kualitatif maupun karena beberapa faktor eksternal. Pengadaan benih sering dilakukan beberapa saat sebelum musim tanam sehingga benih harus disimpan dengan baik agar memiliki daya tumbuh yang tinggi saat ditanam kembali. Pengemasan benih merupakan tindakan penyediaan lingkungan mikro yang optimal agar benih tidak dipengaruhi oleh faktor lingkungan selama penyimpanan. Penyimpanan benih kedelai dilakukan di Gudang Pusat Perbenihan, Leuwikopo IPB mulai April 2018 hingga Juli 2018. Penelitian ini mempelajari pengaruh jenis kemasan dalam mempertahankan umur simpan benih selama penyimpanan. Jenis kemasan tidak berpengaruh terhadap perkecambahan benih dan kadar air, tetapi berpengaruh terhadap potensi tumbuh maksimal dan bobot kering kecambah normal, menggunakan benih yang dikemas menggunakan jerigen plastik dan plastik kedap udara memiliki potensi tumbuh maksimal yang lebih tinggi dibandingkan kertas semen. dan kantong plastik selama umur simpan 4 bulan. Benih yang disimpan selama 1 tahun dalam 4 kemasan mengalami penurunan viabilitas yang drastis, meskipun disimpan pada suhu 17-19° C dan RH 53-55%.

Abstract

Soybean seeds able to degradation during storage. The aims of study were to studying the behavior and deterioration of soybean seed and to predict seed viability during storage in controlled conditions. The experiment used completely randomized design with two levels of variety which nested in storage period with four replications. Two varieties were Dering-1 and Detam 2 that storage in controlled condition at temperature of 19 up to 22 °C and 64 up to 67 percent of relative humidity for six months. The seeds were evaluated for moisture content, protein, peroxide value, electrical conductivity and seed viability. During the deterioration the moisture content, peroxide, electrical conductivity increased while protein content and germination declined. Deterioration model of soybeans can be used to predict the decline of soybean seeds during the controlled storage

Abstract

Vegetative growth of citrus can be increased through a combination of fertilization and pruning. Borneo Prima Mandarin (Citrus reticulata cv Borneo Prima) is a superior local commodity that is grown in lowlands. It has an interesting orange skin, while normally the tropical lowland citrus has a green skin colour. As a new commodity, Borneo Prima Mandarin has to be developed in order to increase production and improve quality. There is no specific cultural practices, so it needs to be developed, especially on fertilizing and pruning. The first experiment aims to observe the plant growth and architecture of plants grown in the orchard. The first factor was the nitrogen fertilization rate (0, 20, 40, 60 g N per tree per application) and the second was pruning (without pruning, open center pruning, hedge pruning). In the second experiment, the plants were applied with the same factors of experiment 1, but were grown on a root observation chamber sized 40 x 20 x 60 cm (length x width x height) which aims to observe the shoot root’s growth and the plant’s biomass. Nitrogen fertilizer had a significant effect to the growth of the Borneo Prima Mandarin, i.e number of shoots and leaves. Twenty grams of nitrogen fertilizer per aplication was efficient to produce new shoots and leaves. Pruning treatments had significant effects towards the plant architecture (i.e reducing plant height, canopy shade projection and canopy length). Open center pruning and hedge pruning made the crown more open which increased the light interception. The shoot grew rapidly two weeks after fertilizing and also pruning. While the root grew rapidly after shoot dormancy.

Abstract

Introduction: Nutmeg seeds are recalcitrant seeds that cannot be stored for long periods of time. The quality of nutmeg seed rapidly declines so that it can affect the productivity of both the seed and its production. This study aims to determine the effect of the storage period and the type of packaging for the storage of nutmeg seeds. Method: This study used a factorial complete block design with the type of packaging factor in several storage periods. Treatment Types of Packaging (K) consisted of four types, namely plastic standing pouch packaging with a size of 14 x 20 cm with a thickness of 0.10 mm (K1), plastic sack packaging which was converted to a size of 17 x 21 cm with a thickness of 0.10 mm (K2), a burlap sack packaging which was converted to a size of 14.5 x 20 cm thickness 0,20 mm (K3), and a rectangular jar measuring 12 x 19 cm thickness 0,20 mm (K4). The storage period was carried out for 12 days (P1), 18 days (P2) and 24 days (P3). The experiment was carried out in room conditions with an average temperature of 28.910C and RH 61.17%. Result: The results showed that storage of nutmeg seeds for 12 days in plastic standing pouch packaging was able to maintain the viability of nutmeg seeds. Storage like this produces seeds with germination capacity (56.25%), moisture content (48.42%), respiration rate (32.35 mmCO2/kg/hour), growth speed (10.5%/etmal), vigor index (9.73) and seed germination capacity. 55.00. Conclusion: Nutmeg seeds should be sown immediately after download. However, with certain storage techniques, nutmeg seeds can still survive with good quality at 12 days of storage in standing pouch packaging with zeolite.

Abstract

Salah satu teknis budidaya yang mendasar untuk peningkatan produksi adalah penggunaan benih bermutu tinggi yang memiliki viabilitas dan vigor yang tinggi. Akan tetapi penentuan viabilitas dan vigor lot benih mengalami kesulitan karena pada umumnya pengujian vigor dilakukan dengan menggunakan benih yang berbeda dengan benih yang ditanam. Penelitian ini ditujukan untuk melihat potensi penggunaan gambar dua dimensi untuk penentuan pertumbuhan dan perkembangan benih kedelai selama proses perkecambahan, serta mengukur pertambahan bobot kering komponen kecambah (tajuk dan akar) selama perkembangan kecambah. Pengecambahan dilakukan dengan menggunakan metode top of paper menggunakan kaca sebagai wadah dan kertas tisu sebagai media pengecambahan. Hasil percobaan memperlihatkan bahwa penggunaan kertas tisu sebagai media pengecambahan memiliki kendala tersendiri dimana akar tanaman dapat menembus permukaan tisu sehingga pengukuran keseluruhan luas permukaan akar secara relatif lebih sulit untuk dilakukan. Meski demikian, penentuan luas permukaan akar dan luas permukaan tajuk dapat dilakukan dengan menggunakan gambar dua dimensi, demikian juga halnya dengan bobot massa kering kedua komponen kecambah tersebut.
