Abstract

Increasing demand on glucomannan as healthy diet in develop countries, promotes higher planting area of Amorphophallus. Iles-iles corm (Amorphophallus muellen) contains high percentage of glucomannan. In order to meet with increasing demand, providing mass planting materials is a great concern in Indonesia. Therefore, the study on skin corm and bulbil as propagation materials was conducted. In the first experiment, bulbil with different size and section, i.e., very small, small, medium and large, and half section and 1f4 section were used. In the second experiment, we evaluated the prospect of skin corm as propagul where different size of skin corm was used, i.e., 1 em x 1 em, 2 em x 2 em, and 4 em x 4 em. Results showed that both bulbil and skin corm could be utilized as prospectivepropagules of iles-iles. Propagation using bulbil was more superior as compared to skin corm. Bulbil of both whole and sectioned had high emergence of bud (> 90%), except very small sized ones. Very small bulbil (diameter less than 1 em) resulted in ca 605 of emergence. Skin corm sized 4 em x 4 em produced equal emergence to medium bulbil. In general, increasing size of skin corm increased success of emergent bud. Delaying emergence on small sized skin corm could be assessed by smaller nutrient reserved. Most unseccessemergence of small sized skin and very small bulbil was due to decay of the propagules. These experiments implied that both bulbils and skin corm could be used as mass propagules for iles-iles production.

Abstract

Corm of iles-iles (Amorphophallus muelleri Blume) is extracted for glucomannan production, a material that is widely used in medicinal, food, and beverage industries. Increasing demand on glucomannan promotes fast expansion of planting area in Indonesia, however, seed availability is limited. The objective of the experiment was to study corm age, planting distance, and planting depth in order to enhance seed production in A. muelleri. Two experiments were conducted under paranet of 65% in Leuwikopo Experimental Farm, Bogor Agricultural University (IPB) from June-November 2015. First experiment used 0- (bulbils), 1-, 2-, 3-, and 4-year-old corms. Second experiment used flowering 3-year-old corms, arranged by factorial of planting distance (0 × 0 cm and 50 × 50 cm) and planting depth (0 and 5 cm in depth). Results showed that flowering of A. muelleri was dependent on corm age, 96% of 3-year-old corms produced flower but none of the 1- and 4-years-old corms produced flower, whereas 8% of 2-year-old corms produced flower. Planting distance did not affect flower growth, while planting at a depth of 5 cm enhanced seed production. Present experiments imply that application of large 3-year-old corms, planting in dense population and at depth of 5 cm could enhance seed production of A. muelleri. It needs further investigation on seed quality from flowering of present treatments.

Abstract

Rice lodging followed by flooding has negatively detriment on the production, however, scientific evident is still rare. As the incident tends to escalate as the impact of extreme weather, hence, research was conducted in order to evaluate rice production and its quality of two rice genotypes treated with lodging-flooding. The experiment was conducted at Leuwikopo Farm IPB Bogor in July-October 2016 using randomized complete block design using two factors, i.e., variety (Way Seputih and Way Apo Buru) and lodging (no lodged [bending 0-18°], lodged [lodged 38-56°], and lodged with flooded [lodged 76-90°]). Rice hill aged 85 days after transplanting was lodged for 15 days. Results showed that lodged with flooded treatment did not increase yield loss although the plant tended to have sterility 5.59-22.00% higher, grain weight 2.05-35.26% lower, and 0.88-10.66% lower value of rice to unhusked ratio. Grains from the lodged-flooded plant had a number of head rice 13.38-15.78% lower, broken rice 0-24.84% higher, and stimulated germination on 1.33-3.40% grains than lodged-without-flooded. It is important to use rice varieties with stable on milling quality to address the lodged-flooded incident.

Abstract

Most of Amorphophallus muelleri seeds for corm production derives from natural production in the forest. The objective of research was to evaluate seed quality and seedling growth from natural and gibberellin (GA3)-induced flowering, and different growing media in order to develop seed production technology. The experiments were conducted at Leuwikopo Experimental Farm of Bogor Agricultural University, Bogor, Indonesia from August 2016-April 2017. A. muelleri seeds from six culture practices were compared, i.e., mother corms with natural flowering were planted in soil media, soil+rice husk charcoal, and soil+cow manure, and mother corms induced flowering using GA3 (1.000, 1.500, and 2000 ppm) were planted in soil media. Results indicated that berry size, color, seed color and size and seed germination rate were independent of seed production method, i.e., non-induction, GA3 induction, and growing media. Germination rate was >90%, and no abnormal sprouting was found. The highest seedling establishment, represented by full-expand of first leaf, was obtained from seeds of soil+rice husk charcoal media. Seedling from seeds of soil+rice husk charcoal and soil+cow manure media had larger leaves than the other treatments. Present study implies that application of rice husk charcoal or manure in the seed production of A. muelleri is important to obtain high quality seedling.

Abstract

Ambon Forest nutmeg (Myristica fatua Houtt) is one of the endemic plants in Indonesia. The morphological characteristic of Ambon Forest nutmeg is slightly different from that of Banda nutmeg (Myristica fragrans Houtt) i.e., it is not used as spices, but its oil is used as a lamp oil. This study aimed to determine the chemical components and essential oils of Ambon Forest nutmeg derived from its seeds, mace, and flesh compared to Banda nutmeg. Extractions of essential oils were performed using a steam hydro-distillation. Analysis of chemical compositions and contents of essential oil was carried out using a Gas Chromatography-Mass Spectrometry (GCMS) instrument and SNI 06-2388-2006 method. The essential oil contents in Ambon Forest nutmeg were relatively low, i.e., 0.63% in the seeds, 0.30% in the mace, and 0.04% in the flesh compared to Banda nutmeg i.e., 1% in the seeds, 40% in the mace, and 3.5% in the fruit flesh. The chemical compositions of essential oils showed that M. fatua Houtt contained 12 compounds in the seeds, 24 compounds in the mace, and 17 compounds in the fruit flesh, while for Banda Nutmeg, the contents of essential oils were found 18 compounds in the seeds, 10 compounds in the mace, and 15 compounds in the fruit flesh. M. fatua Houtt contained the highest Copaene, i.e., 28.41% in the seeds, 10.42% in the mace, and 23.33% in the fruit flesh. Myristicin, as the main marker compound of nutmeg oil, was also found in Ambon Forest nutmeg i.e., 1.3% in the seeds, 1.16% in the mace, and 5.19% in the fruit flesh. However, these results showed lower contents when compared to Banda nutmeg with Myristicin contents of 8.72% in the seeds, 10.14% in the mace, and 10.46% in the fruit flesh. Keywords: Essential oil, Myristica fatua Houtt, Myristica fragrans Houtt, Nutmeg

Abstract

The increasing popularity of leaf and fruit of African nightshade as vegetables in Indonesia stimulates farmers to harvest both leaf and fruit from single plant alternately; the yield is presumably affected by fertilizer rate, e.g., nitrogen. The present study aimed to evaluate such hypothesis through evaluation of plant production, N absorption, and its status. Seedlings were treated with five N levels, i.e., 0, 90, 180, 270, and 360 kg/ha in Leuwikopo Experimental Farm, IPB Bogor, Indonesia. The results revealed that leaf and fruit productions were sensitive to nitrogen level. Leaf and fruit productions had quadratic correlation to N levels, i.e., r 2=0.9671 and r 2=0.9483 with optimum dosages as 304.8 kg/ha and 336.5 kg/ha, respectively. Proper N application is important for both leaf and fruit productions because nitrate level in leaf had quadratic relationship (r 2=0.5264) and it has a linear relationship in fruit production (r2=0.9587) by increasing N level from 90 to 360 kg N/ha. From the total fresh mass leaves and fruits harvested, the optimum N for the best alternate harvesting was 271.1 kg/ha (r 2=0.9644). Keywords: African nightshade, intercropping, N uptake, nitrate status, photosynthetic rate

Abstract

ABSTRACTIndigenous vegetables have become popular in recent Indonesian diet, but agronomic and economic studies on these crops are limited. The objective of this research was to investigate the cultural technique of indigenous vegetables, their uses and economic importance in West Java, Indonesia. Initial market observation was conducted in Bogor to determine the economic value of indigenous vegetables. In depth observations of the indigenous vegetables and interviews with merchants, farmers and consumers were conducted in three districts, i.e., Bogor, Cianjur and Tasikmalaya, focusing on four indigenous vegetables familiar to local people, i.e., genjer (Limnocharis flava (L.) Buchenau), kenikir (Cosmos caudatus Kunth.), leunca (Solanum americanum Miller) and poh-pohan (Pilea melastomoides (Poir.) Wedd.). This study showed that indigenous vegetables have been produced in extensive and semi-intensive cultivations and are sold in local markets daily, although local people do not consume them frequently. Indigenous vegetables held a market share of less than 5% at local markets, and accounted for less than 10% in household vegetable consumption. The reasons for consumers to choose indigenous vegetables were familiarity to these crops, moderate prices, family members’ preference, availability and ease of preparation. Generally, younger family members (<30 years old) bought indigenous vegetables less frequently than older ones (>30 years old), possibly due to lack of information on its use, unfamiliar flavor and high availability of other commercial vegetables commonly grown worldwide.Keywords: Cosmos caudatus, Limnocharis flava, local knowledge, Pilea melastomoides, Solanum americanumABSTRAKPopularitas sayuran indigenus terus meningkat di Indonesia, namun studi agronomi dan ekonominya masih terbatas. Penelitian bertujuan mengkaji budidaya, pemanfaatan dan nilai ekonomis sayuran indigenus di Jawa Barat, Indonesia. Penelitian pendahuluan dilakukan di pasar di wilayah Bogor. Penelitian mendalam dilakukan dengan mewawancarai pedagang, petani dan konsumen, serta mengamati di lahan petani di tiga kabupaten yakni Bogor, Cianjur dan Tasikmalayauntuk empat sayuran indigenus utama yakni genjer (Limnocharis flava (L.) Buchenau), kenikir (Cosmos caudatus Kunth.), leunca (Solanum americanum Miller) dan poh-pohan (Pilea melastomoides (Poir.) Wedd.). Studi menunjukkan bahwa sayuran indigenus diproduksi secara intensif dan semi intensif, serta dijual di pasar setiap hari, walaupun penduduk setempat tidak mengkonsumsi secara teratur. Sayuran indigenus mengisi celung pasar kurang dari 5% dan memenuhi kurang dari 10% kebutuhan sayuran rumah tangga. Konsumen memilih sayuran indigenus karena sudah terbiasa mengkonsumsi, harga terjangkau, disukai anggota keluarga,ketersediaan dan kemudahan mengolah. Secara umum, anggota keluarga muda (usia < 30 tahun) lebih jarang membeli sayuran indigenus dibanding yang lebih tua (usia > 30 tahun), kemungkinandisebabkan keterbatasan informasi nilai guna, adanya aroma asing, dan ketersediaan sayuran lain.Kata kunci: Cosmos caudatus, Limnocharis flava, pengetahuan lokal, Pilea melastomoides, Solanum americanum

Abstract

ABSTRACTThere are many studies on agronomic and economic advantages of iles-iles (Amorphophallus muelleri Blume), leading to high demand on seed to support the rapid production expansion in many Asian countries. By contrast, there are few studies on flowering phenology and flower morphology although they affect the seed production. Therefore, we evaluated flowering phenology and flower morphology of 80 plants of A. muelleri grown in a field under 65% artificial shading net at Leuwikopo Experimental Farm IPB Darmaga, Bogor, Indonesia from May 2015 to July 2016 in order to improve seed production. A. muelleri produced solitary spadix, with female flowers at the lower part and male flowers at the upper part. Spadix grew slowly for 56-71 days after bud break, and then grew rapidly thereafter for 30-35 days until anthesis. Seed was harvested 9.6 to 10.2 months after anthesis. We devided the development of spadix into seven phases, bud break as stage I and berry maturity as stage VII. Stage VI to VII determined seed production. Seed production was also affected by roots formation and spadix size. There were strong positive correlations between lengths of the female zones with berry production. Some morphological characteristics of spadix were dependent on corm size, thus, it was likely that agronomic improvement to enhance female flower and corm sizes wasimportant in seed production.Keywords: developmental stage, female flower, iles-iles, male flower, seed production ABSTRAKTelah banyak kajian keunggulan agronomi dan ekonomi iles-iles (Amorphophallus muelleri Blume), sehingga mendorong peningkatan permintaan benih untuk mendukung perluasan areal produksi di banyak negara Asia. Namun demikian, kajian fenologi dan morfologi bunga khususnya terkait produksi benih masih terbatas. Oleh karena itu, kami mengkaji perkembangan dan morfologi 80 bunga iles-iles yang ditanam di bawah paranet 65% di Kebun Percobaan Leuwikopo IPB, Bogor, Indonesia dari Mei 2015 sampai Juli 2016 dalam rangka perbaikan produksi benih. Iles-iles menghasilkan sebuah tongkol bunga dengan bunga betina pada bagian bawah dan bunga jantan pada bagian atas. Tongkol bunga tumbuh lambat 58-71 hari setelah pecah tunas, diikuti tumbuh cepat 30-35 hari hingga antesis, dan biji dipanen 9.6 sampai 10.2 bulan setelahnya. Perkembangan bunga dari pecah tunas hingga buah matang dapat dibagi menjadi tujuh tahap. Tahap VI ke tahap VII menentukan keberhasilan produksi biji iles-iles. Selain itu, keberhasilan produksi biji juga dipengaruhi oleh keberadaan akar dan ukuran tongkol khususnya panjang bagian bunga betina. Beberapa karakter morfologi bunga iles-iles dipengaruhi oleh ukuran umbi saat tanam. Oleh karena itu, perlu perbaikan agronomis untuk meningkatkan ukuran umbi dan ukuran bunga betina guna mendukung produksi benih.Kata kunci: bunga betina, bunga jantan, iles-iles, produksi benih, tahap pertumbuhan
