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

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.

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

This study aims to determine the population and genetic parameters of population F3 result of selection pedigri red rice crosses Silopuk with Fatmawati Superior Varieties using Augmented Design. Silopuk cultivars with red and inlaid rice characteristics while Fatmawati varieties with characteristics of large grain size, high production, high grain number, early age and white rice. The crosses are expected to produce high, large grain size, large amount of grain, maturity and color of brown rice. This research was conducted August-November 2016 at UPT Farm Faculty of Agriculture Andalas University. The genetic material used is the seed of the generation of F3 (F3-5, F3-12, F3-55, F3-95, F3-118, F3-122) derivatives of red rice crosses Silopuk with Fatmawati and the seeds of the two elders as a comparison with the experimental method using Augmented Design. The results of this study indicate the F3 population character number of filled grains per panicle is higher than the two parents with a wide range and other characters are between the two parents. The phenotypic diversity of flowering age characters in the F3-122 family is (2,41) and 1000 weight of pithy grains in the family F3-5 (2,31) ; F3-55(2,39) and F3-95 (3,49) relatively narrow. However, heritability in the broadest sense and genetic variability for all characters ranges from moderate to high and narrow to broad. Estimated genetic progress with 5% intensity in F3 population has high criteria for all characters (age of flowering, harvest age, plant height, stem length, total tillers, number of productive tillers, total grain / panicle, percentage of filled grains / panicle , total grain weight / clump and weight of filled grain / clump) except panicle length characters and 1000 grain weight of filled grains. Differential selection of population F3 with 10% selection intensity based on 1000 grain weight of pith grain, plant height and total grain weight per hill obtained 31 selected individuals. Selected individuals will be forwarded to the F4 generation

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

Maintaining the availability of high quality of seed on-time is one of the major problems in the production of large white ginger seed rhizomes (LWG). LWG seeds cannot be stored for a long period of time because it is easily wrinkled and sprouted during the storage. This study aimed to understand the effect of PBZ treatment time and concentration on the quality of LWG seeds during the storage. This study used a randomized square experimental design with three replications. The main plot is the time of application of paclobutrazol: 1) 4 months after planting (MAP) and 2) 5 MAP, and as subplots are five levels of PBZ concentration : 0, 100, 200, 300 and 4 00 ppm. The results showed the treatment of PBZ 400 ppm at 4 and 5 MAP was the best concentration in increasing the shelf life of LWG seeds: growth speed (4.8% / etmal ), seedling height (60.38 cm) and dry weight of seedlings (1.51 g) after stored for 4 months compared with no PBZ treatment.
