Abstract

Irmawati I, Priadi DP, Marlina M, Sodikin E, Ria M, Amelia CR. 2022. The application of NPK fertilizer through root infuse system on rubber plant (Hevea brasiliensis). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 793-799.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The application of fertilizer with an infuse system is one alternative to increase the efficiency of fertilization on rubber plants. Root infuse systems are considered advantageous because of the reduced risk of fertilizer loss due to leaching and evaporation. For this reason, this study was conducted to determine the efficiency of NPK absorption through a root infuse system in rubber plants (Hevea brasiliensis). The research was carried out from September to December 2020 at the ATC rubber plantation, Faculty of Agriculture, Sriwijaya University. This study used a randomized block design with 4 treatments consisting of N0 = control, N1 = 80 grams of NPK per plant, N2 = 100 grams of NPK per plant, N3 = 120 grams of NPK per plant. The observed variables included the volume of absorbed solution, leaf greenness level, and NPK content in plant leaves. Based on the results, it was concluded that NPK fertilization using root infuse system on rubber plants had a significant effect on the variables of the volume of absorbed solution at 3rd and 4th weeks, and leaf greenness level. The higher the concentration of solution, the slower and less solution was absorbed by the plant.

Abstract

Simamora IA, Gustiar F, Zaidan Z, Irmawati I.  2022. Potential of chaya (Cnidoscolus aconitifolius) as a source of nutrious vegetables for Indonesian people. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 937-946. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Chaya (Cnidoscolus aconitifolius (Mill.) IM Johnst.) is an annual plant species that is not widely known by the Indonesian people. This plant has not been cultivated intensively, although Chaya is a type of vegetable plant that is rich in nutrients and has many benefits. This writing aimed to provide information on the study of the potential development of Chaya plants as a source of food, feed or as medicinal ingredients. In a tropical climate, Chaya plants have great potential to be developed as cultivated plants. This paper will examine the potential of Chaya from the aspect of agricultural cultivation and utilization of Chaya leaves. The lack of information and public knowledge regarding the nutritional content and benefits of Chaya is one of the inhibiting factors for plant development. This plant is easy to grow by propagation of stem cuttings, currently the chaya plant is still being developed on unproductive land and used as a hedge plant. With the development of information system media, it is hoped that it will increase public knowledge of the potential and benefits of Chaya leaves.

Abstract

The aimed of this study was to determine the effect of chicken manure application on red chili plants using conventional and floating cultivation techniques. The research was carried out on the experimental farm for conventional cultivation techniques and in research pond for floating cultivation located in the Faculty of Agriculture, Sriwijaya University, Indralaya Campus, Ogan Ilir, South Sumatra with an altitude of 10 m above sea level from July to November 2022. The experiment used a randomized block design with one factor, namely chicken manure (0, 10, 20 and 30 tons/ha) with three replications. While the floating experiment used 200 cm x 100 cm of bamboo rafts. Parameters observed included plant height, number of leaves, crown diameter, fruit length, fruit diameter, fruit weight per fruit, and total fruit weight per plant. Data were analyzed using Analysis of Variance (ANOVA) at the 5% level. The results showed that increasing the dose of chicken manure up to 30 tons/ha in both cultivation techniques increased plant height and number of leaves. Likewise for the number and weight of fruit, obtained at the same dose in conventional techniques, namely 30 tons/ha. However, fruit length and diameter parameters were higher in floating cultivation at all doses of chicken manure treatments. Therefore, it was concluded that the use of chicken manure could increase the growth of chili plants in both cultivation techniques, although the size of the polybags used could not support the growth and yields optimally.

Abstract

Rice serves as Indonesia's main food source, but inadequate storage conditions can lead to seed deterioration and diminished germination performance. To enhance the viability and vigor of stored seeds, this study explores various priming methods' effects on multiple rice varieties. Employing a completely randomized design (CRD) with two factors, the first factor involves rice varieties (V) categorized by germination ranges: 41–50% (V1 = Toyonishiki, V2 = Yoneshiro), 51–60% (V3 = Jaya, V4 = IR50), 61–70% (V5 = Fortuna, V6 = Sulutan), and 71–80% (V7 = IR 24, V8 = Inpago 5). The second factor is seed priming (P), including control, hydropriming, and osmopriming. Results indicate that priming enhances maximum growth potential, germination percentage, vigor index, growth speed, plumule and radicle length, as well as fresh and dry weight. Hydropriming outperforms osmopriming, particularly in vigor index, growth speed, plumule and radicle length, and dry weight. Priming proves more effective in improving maximum growth potential, germination percentage, vigor index, and growth speed at lower germination percentage ranges (41–60%). The most significant priming-induced increases in radicle length, fresh weight, and dry weight occur in higher germination percentage ranges (61–80%)

Abstract

Amelia, I., Susilawati, S., & Irmawati, I. (2023). The effect of various doses of chicken manure on the growth and yield of shallot plants (Allium ascalonicum L.) bauji varieties use polybags. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 405-416). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Providing organic fertilizer is important for shallot plants (Allium ascalonicum L.) because organic fertilizer has advantages compared to inorganic fertilizer, namely that it is more environmentally friendly and safe when applied to soil media. One type of organic fertilizer that is often used by farmers is chicken manure. Chicken manure contains quite high levels of nitrogen, phosphorus and potassium nutrients which are useful for shallot plants. This research aimed to determine the best dose of chicken manure for the growth and yield of shallot plants (Allium ascolanicum L.) of the bauji variety. The research was carried out at the Sriwijaya University Campus Experimental Garden, South Sumatra at the coordinates 3 13'29.74”S 104 38'54.13”E which was carried out in June-August 2023. The design used was a Randomized Block Design (RBD) with 3 replications. The dose of chicken manure used is 10 tons/ha (40 g/polybag); 20 tons/ha (80 g/polybag); 30 tons/ha (120 g/polybag) and without chicken manure as a control. Parameters observed included leaf length, number of leaves, number of tillers, leaf greenness level, total chlorophyll content, leaf area, root length, number of tubers, tuber diameter, tuber length, tuber volume, fresh weight of tubers, dry weight of tubers, fresh weight, bushmeat and dry weight of bushmeat per plant. The results of the study showed that the application of chicken manure had a significant effect on the growth and yield of shallot plants. Giving chicken manure at a dose of 120 g/polybag resulted in better number of leaves, leaf greenness, leaf area, number of tubers and tuber production compared to giving other doses of chicken manure.

Abstract

Susilawati, S., Sodikin, E., Sulaiman ,F., & Irmawati, I. (2023). The effect of bulb size on the initial growth of three varieties of shallot (Allium ascalonicum L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 151-162).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Both vegetative (using bulbs as planting material) and generative (using seeds) methods can be used to cultivate shallot plants. Although using bulbs is simpler, it has a number of drawbacks, including the need for more seeds, relatively high costs, and the challenge of planning a planting timetable. In order to support the growth of three types of shallots, this study sought to assess the strength of the correlation and regression models of the bulb features.  The study was carried out during June and July 2023 in Tanjung Pering Village, Indralaya Utara Subdistrict, Ogan Ilir, South Sumatra, at coordinates 003 13'00" LS and 104 38'16" E. A Randomized Block Design with two components and three replications was employed in the study. The first factor is the utilization of three different varieties: Bauji, Bima Brebes, and Tajuk. The second component is bulb size, which comes in three sizes: small (1.5 cm), medium (1.5 cm to 2.0 cm), and large (>2.0 cm). The research plot measured 150  cm by 100 cm, and each treatment plot had 21 plants. The parameters that were measured included the bulb character, which included the diameter, weight, length, and volume of the bulb, and the bulbs initial growth, which included the leaf length, number of leaves, tillers, and SPAD value. Based on the coefficient of determination (R2), the findings demonstrated that the linear zero-intercept model consistently performed better than other regression models in correlating bulb diameter with bulb length, weight, and volume. The Tajuk variety had the most leaves and tillers but the lowest SPAD score when varieties and bulb sizes were combined early in growth. Shallot plants develop best in their early stages on little bulbs. Conclusion the most accurate model for correlation between bulbs characters uses a zero intercept linear regression model.
