Abstract

Irmawati, I., Sefrila, M., Susilawati, S., Tambunan, R. T., Poerbaputra, Y. D., Sinaga, A. P. P., Praptawara, M. Y. A., Hutabarat, R. V. M., Simanjuntak, R. (2024). Morphophysiological characteristics and production of bima brebes shallot variety by providing liquid organic fertilizer in a floating cultivation system. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 202–211).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Shallot cultivation requires the application of technology that is appropriate to the conditions of the agroecosystem plants being planted in order to provide high yields. This research aimed to determine the growth and yield of shallot plants of the Bima Brebes variety which are cultivated using a floating farming system with the addition of liquid organic fertilizer. This research was structured using the Randomized Group Design (RAK) method by carrying out 4 treatment levels, namely P0 = Control (100% NPK), P1 =4 mL L-1POC, P2 = 8 mL L-1 POC, P3 = 16 mL L-1 POC. The results of the diversity analysis showed that the application of liquid organic fertilizer (POC) given to the plants showed that the results were not significantly affected in all growth parameters of the shallot plants. Parameters observed included plant height, number of tillers, number of leaves, level of greenness of leaves, fresh weight of berries, fresh weight of tubers, dry weight of berries, air dried weight of tubers, and tuber diameter. The best leaf length of shallot plants was found in treatment P3 with plant height reaching 32.37 cm. This shows that liquid organic fertilizer can meet the nutrient needs of shallot plants for plant height growth. Research shows that the application of liquid organic fertilizer with treatment at a dose of 16 mL L-1 is able to provide the best results for all parameters of growth and yield of shallot plants.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 799–816).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Shallots are one of the plants that produce economically valuable bulbs that can becultivated conventionally or with a floating farming system. The purpose of this study was to determine the impact and best dosage of providing variations in chicken manure fertilizer with a floating system on the growth and yield of shallots (Allium ascalonicum L.) tajuk variety. This research was conducted at the Embung Faculty of Agriculture, Sriwijaya University with coordinates 003 ° 13'16 "LS and 104 ° 39'03" BT in July to August 2024. The study was conducted using a Randomized Block Design (RAB) consisting of 4 treatments and 3 replications. The variation of fertilizer doses used in this study were P0 = Control (Without chicken manure fertilizer), P1= 10 Tons/ha (40 grams of chicken manure fertilizer/polybag, P2= 20 Tons/ha (80 grams chicken manure fertilizer/polybag), P3 = 30 Tons/ha (120 grams of chicken manure fertilizer/polybag). The parameters observed were plant height, number of leaves, leaf area, leaf greenness level per week, leaf greenness level per hour, leaf growth age, fresh weight of shoots, dry weight of shoots, number of tillers, number of bulbs, bulb length, bulb diameter, bulb volume, fresh bulb rice, air dried of bulb weight, and root length. The results of the study showed that variations in the dose of chicken manure fertilizer did not have a significant effect on the growth and yield of shallots planted in a floating system. Even so, a dose of 10 tons/ha or 80 grams/polybag (P2) produced better growth and production than other treatment.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 667–678). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The Duku plant (Lansium domesticum) is one of the popular tropical fruit in indonesia. Using the idea of plant cells' totipotency, tissue culture is an alternate method for a quick and massive propagation of high-quality duku plant seedlings. This research was aimed to evaluate different sterilization materials and procedures on duku leaf midrib explants through tissue culture. The research was conducted from June to September 2024 at Tissue Culture Laboratory, Department  of  Agronomy, Universitas Sriwijaya (2°59’23.4”S 104°43’53.4”E). A combination of  sterilizing substances, including 70% alcohol, fungicide, bactericide, liquid detergent, and NaOCl, were utilized in this sterilization procedures. The percentage of live explants, browning explants, and explants infected with bacteria or fungi then were calculated using parametric descriptive analysis. The results showed that the P3 treatment's sterilant combination liquid detergent for 3 minutes, 0.2% of fungicide and bactericide for 10 minutes, 1% NaOCl for 15 minutes, and 70% alcohol for 5 minute produced the highest percentage of live explants (46%) with a relatively low percentage of contaminated explants (30%) and the lowest percentage of browning explants (23%). Thus P3 treatment was concluded as the best treatment to reduce the contamination level and browning of duku leaf midrib explant.

Abstract

[GROWTH AND HARVESTING FREQUENCY OF RED CHILI PLANTS WITH THE APPLICATION OF  NPK FERTILIZERS CULTIVATED ON SUB-OPTIMAL LAND IN FLOATING CULTURE SYSTEM]. The low productivity of red chili in South Sumatra is mostly due to its cultivation was conducted in sub-optimal land that is less favorable for producing vegetable crops. This study aimed to evaluate growth and yield of red chili plants under suboptimal conditions using various doses of NPK fertilizer. The experiment was carried out from June to October 2022, at the water reservoir and experimental field (as a comparison) at the Faculty of Agriculture Universitas Sriwijaya, Indralaya, South Sumatra with an altitude of 10 m above sea level. Both experiments were arranged in a randomized block design with three replications and one factor in the group, namely NPK fertilizer doses (0, 5, 10, and 15 g/polybag). For the experiment in the water reservoir, each treatment was arranged randomly in a 200 cm x 100 cm bamboo raft (for each group). The results showed that the application of NPK fertilizer in floating cultivation did not increase plant height, number of leaves, shoot diameter, and harvesting frequency of red chili. It was concluded that the application of NPK fertilizer in floating cultivation did not increase growth and harvesting frequency of red chili.

Abstract

The utilization of swamp land in cultivating rice plants has obstacles, especially the presence of abiotic stress, which are submersion in the vegetative phase and drought in the generative phase which impacts productivity. The use of superior varieties that can withstand submersion and drought stress can be a solution in increasing rice productivity in swamp land. This study aims to evaluate the growth and production performance of BC2F4 generation accessions, in shallow swamp land. This study was conducted in Pelabuhan Dalam Village, Pemulutan District, Ogan Ilir Regency, South Sumatra from June to October 2024. This study used a Randomized Block Design using accessions resulting from BC2F4 crosses, including; T1, TR1, T2, TR2, T3, and TR3, as well as Inpago 5 varieties (recipient parents) and IR 64 (popular varieties). The results showed that all BC2F4accessions showed better growth and yield performance compared to Inpago 5. The T3 variety showed the highest productivity at 3.25 tons/ha. In addition, the Pearson correlation showed that productivity was influenced by the variables of the number of tillers (0.58), productive tillers (0.68), and grain weight per panicle (0.89).

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.
