JERAMI : Indonesian Journal of Crop Science Vol 1 No 1 (2018): JIJCS
Publisher : Department of Crop Science, Faculty of Agriculture, Andalas University

Application of system of rice intensification (SRI) method has been considered as one of powerful efforts to increase the harvested yield by modifying the plant and itssurrounding environment. This study was aimed to determine the effect of different environment towards the response of rice varieties grown using SRI method. Two rice varieties, Batang Piaman and IR-42 were grown in District of Tanjuang Barulak (Regency of Tanah Datar) and District of Saniang Baka (Regency of Solok). Plant height and several yield parameters, such as productive tillers, panicle length, grain number per panicle, and yield per plot were assessed from both varieties and locations. Statistical analysis was conducted using randomized block design (RDB) and significance was further evaluatedusingDuncan’s New Multiple Range Test (DNMRT) with a p>0.05. Batang Pariaman appeared in taller performance than IR-42. Regarding the number of productive tiller, Batang Piaman resulted more productive tillers in Solok, while IR-42 was dominant in number of productive tiller compared to Batang Piaman in Tanah Datar. Unlike IR-42, Batang Piaman exhibited longer panicle, more grain amounts per panicle, and higher yield per plot than IR-42 in both locations.

Most of rice seeds experience after ripening problem which then result in seed dormancy. This kind of dormancy could be broken through various types of treatments, including storaging in dry place for certain period. This study was aimed to evaluate the combination between seed water content and storage duration to induce the seed germination of local genotype brown rice, Daro Merah. Various levels of seed water content (6-10, 11-15, 16-20 and 21-25 %) and storage duration (2, 4, 6 and 8 weeks) were evaluated to identify its effect on Daro Merah seed germination. Data were analyzed using two-way analysis of variance where significance were further proceeded using Duncan’s New Multiple Range Test with a p>0.05. The results showed that seed germination of Daro Merah reached 95 % at five days after seeding when the seed water content was maintained at 6-10% and stored for 8 weeks. After 14 days, the germination reached 99 % and most of the seeds showed some shoots emerged from the soil. Keywords: Brown rice, germination, seed water content, storage duration, Daro Merah

Andalehis the local name of MorusmacrouraMiq. in West Sumatra, Indonesia. Nowadays, this dioeciously speciesis in endangered situation. The aim of the research is to find out the appropriate combination of plant growth regulator to induce shoot multiplication of explants from male and female trees of andaleh. The plantlets from this research will be used in the next future to conserve this endangered species in vitro and in vivo, especially in preparing parental material in breeding program. Young buds from male and female trees were used as an explants in basal medium Murashige and Skoog supplemented with BAP (0.5, 1.0, 1.5 and 2.0 mg.L-1) in combination with NAA (1.0 mg.L-1 for each). The frequency of bud break was 50 % in MS medium supplemented with BAP (0.5 mg.L-1) and NAA 1.0 mg.L-1 for both source of explants (female and female trees of andaleh) after 3 weeks of culture. Generally, the number of shoot induction was very low. On the other hand, the rate of callus formation was high (100%) in highest BAP concentration (2.0 mg.L-1).

Soybeans undergo rapid deterioration due to its chemical composition and unfavourable storage conditions. The objective of the research was to determine the length period of seed hidration and dehydration which is integrated with rhizobateri to viability and vigor of deteriorated soybean seed. A completely randomized design with four replicates were used in this experiment. Seeds were treated with varied combination of hydration period in a rhizobacteria suspension and followed by dehydration time. Data were analysed using the F-test and significant differences were further tested with Least Significant Difference at the 5% level. Results showed that the hydration and dehydration period of seeds in a rhizobacteria suspension improved viability and vigor of seed which have 59.5% initial germination percentage. The improvement was 12.28%, 0.56, 25.4% and 1.4 days for standard germination test, vigor index, first count test percentage and T50, respectively. The hydration for 60 minutes followed by dehydration for 60 minutes gave the best results on seed viability and vigor.

Characterization of Agronomic and Quality from Three Clones of Ramie Plant (Boehmeria nivea [L.] Gaud.) in Ultisol Limau Manis Reni Mayerni
JERAMI : Indonesian Journal of Crop Science Vol 1 No 1 (2018): JIJCS
Publisher : Department of Crop Science, Faculty of Agriculture, Andalas University

The quality improvement of ramie, including inner and outer aspects are required to be developed to optimalize its production. Unlike horticulture and food crops, ramie cultivation is not constrained by the soil type. This study was aimed to evaluate the agronomical characteristics of three ramie clones in ultisol land. This study was performed using descriptive analysis method with purposive sampling by collecting 10 clumps per clone. Clones of fiber ramie used were Ramindo 1, Bandung A and Lembang A. All clones were planted in ultisol soil located in 350 m above sea level from September 2015 until March 2016. The highest fiber production was achieved from Ramindo 1 followed by Bandung A and Lembang A. The resulted fiber from all clones was considered as quality class II fiber marked by the nominal value ranging from 400-450. Bandung A exhibited the best quality of fiber with nominal value of 450. In terms of its chemical composition, fiber produced by Lembang A contained the highest cellulose (74.7%) with the lowest lignin content (3.6%).

Publisher : Department of Crop Science, Faculty of Agriculture, Andalas University

Red pitaya is getting more popular in Indonesia recently as one of high antioxidant sources with a promising economic value. However, the production of this CAM plant is restricted by low success percentage of its natural pollination and self incompatibility problems. Therefore, artificial pollination is required to overcome these problems and increase its yield. This study was aimed to evaluate the effect of pollination models towards the yield of red pitaya. This study was conducted using randomized block design with three pollination models applied into nine groups. Pollination models used were open pollination (P1), hand-self-pollination (P2) and hand-cross pollination (P3). Several floral-related parameters, including the elongation of flower bud, diameter of blooming flower, length of stigma, number and length of anthers, were assessed. Effect of different pollination models was also observed through some yield-related parameters, such as fruit weight, fruit diameter, fruit length, harvesting age and number of fruit sets. This study revealed that hand cross pollination produced the best yield performance showing 541.1 gram of fruit with 11.5 in length and 8.66 cm in diameter. Harvesting age and number of fruit sets showed no significant difference among those three pollination models. Keywords: Pollination, red pitaya, yields, fruits, flowers
