Abstract

Thamrin et al. 2012. Productivity and Resistancy of the Tungro-resistant Rice Variety in South Sumatra. JLSO 1(2):130-137. The establishment of new varieties is required to have the advantage of being more diverse and specific according to agroecosystem, problems in the field, the specific location and consumers’ preference. Prior to its establishment, a tungro-resistant rice variety needs to be tested locally. This research was carried out on the rain-fed rice field at the village of Lubuk Seberuk Sub-district Lempuing, Ogan Ilir Komering Regency (OKI)  in 2009.  This research employed randomized block design (RGD) with 10 treatments consisted of eight strains and two improved varieties as a comparison. Each treatment was repeated 3 times. The results indicated that strain B-10018G-TB-42-1 has the least tungro attacks and the highest number of tillers and production compared to the other strains and varieties.

Somantri RU, Syahri S, Thamrin T. 2019. Agronomic and economic analysis of soybeans which is grew by monoculture and polyculture systems in South Sumatra. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):159-172.  The presence of shade and other limiting factors in the crops of plantation plants will certainly affect the growth and soybean yield were compared by monoculture. The objective of the research was to know of agronomic performance and farming feasibility of soybeans which are cultivated by polyculture and monoculture systems. Soybeans were planted in two systems namely monoculture (soybean) and polyculture (soybean are intercropped with 3 years of rubber trees).  Both of Dena 1 and Anjasmoro varieties were cropped in those systems. Soybeans are cropped by using planting machine (ATBJ) which has planting distance 20 cm x 40 cm (1-2 seeds per hole). Plants were fertilized with 50 kg Urea per ha, 150 kg TSP per ha, 150 kg KCl per ha, manure 2,000 kg per ha, and dolomite 1,000 kg per ha. Mower were used for harvesting. The results showed that the growth and soybean yield in monoculture system was better than the polyculture. Yield of Anjasmoro in monoculture was 15.35 ku per ha, whereas the polyculture was 4.72 ku per ha. Meanwhile, the productivity of Dena 1 was 14.80 ku per ha and 7.38 ku per ha in polyculture system. The polyculture had a higher value of the land equivalent ratio than monoculture of rubber trees. Economically, the two planting systems that were examined also deserve to be done by farmers, where the value R/C > 1

Abstract

Somantri et al, 2019. Potential of Several Soybean Varieties in Dry Land of South Sumatera. pp. 473-481. Soybean productivity is determined by climate, land suitability also innovations applied such as the use of superior varieties.  Soybean cropping areas mostly covers ricefield and dry land in South Sumatera, in where rice field fertility is better than dry land.  With total of 364.583 Ha dry land, soybean cultivation is potential to be developed in South Sumatera to obtain self-sufficiency and minimize soybean imports.  The activity was carried out in Talang Ubi Sub-district in Penukal Abab Lematang Ilir (PALI) District in 2018.  The study was aimed to understand the growth and yield of some adaptive soybean superior varieties (VUB) in dry land of South Sumatera.  Technologies applied was the use of several soybean VUB i.e. Burangrang, Dering 1. Demas 1 dan Anjasmoro, fertilizer based on Dry Land Test Kit (PUTK), the use of manual grains seeder (ATBJ), Rhizobium application on seeds and integrated pest control. The result showed that the highest yield was obtained from Dering 1 for 2,3 t/ha of dry seed and the lowest was Burangrang for 1,36 t/ha.

Syahri S, Somantri RU,  Thamrin T. 2019. Dissemination technology to enhance farmers knowledge and rice production in swamps of South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp. 584-594.  Palembang: Unsri Press. The government continues to strive in order to increase rice production, especially in swamps. In fact, at the end of 2018, the Ministry of Agriculture initiated the SERASI program’s. However, adoption of technologies at farmers level are still very slow. So that, South Sumatra AIAT always campaign the good agricultural practices which have been produced by IAARD. It was done to improve the welfare of farmers, especially on swampy. The activity was carried out on 12 farmer groups in Jukdadak village, Tanjung Lubuk subditsrict, distrcit of OKI from May to December 2018. Dissemination of technology is done through several methods, including: 1) making an integrated rice crop management demonstration plot of 5 ha, 2) socialization of 2.5 ha of new rice varities, 3) technology dissemination through farmer training, 4) farmer group meetings, 5) technology demonstrations, and 5) dissemination of dissemination material produced by the IAARD. The technologies which has introduced in demonstration plot includes the Legowo 2:1, the use of adaptive varities (Inpari 30 and Inpari 43), fertilization based on the results of soil test kit and pest control based on IPM principles, 21 days seedling, making local microorganism (MOL) and the use of leaf chart and PUTR. The parameters analyzed included the growth and rice yield on both of demonstration plot and display, increasing farmers' knowledge, and increasing rice productivity. The results show that rice productivity at the demonstration plot location and varities socialization averaged 4.8 t/ha (Inpari 30) and 4.0 t/ha (Inpari 43). The technology dissemination was able to increase rice productivity at the assisting location, which reached 19.1% compared to the previous year. In addition, an increase in farmers' knowledge in carrying out rice cultivation, especially in the swampy swamp land.Keywords: technology dissemination, farmers knowledge, rice production, swamp, Sumatera Selatan

Syahri S, Somantri RU, Hutabarat YPAP. 2019. Study of hazton systems on paddy in swamp area, South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp. 163-177. Palembang: Unsri Press. The study was carried out on 3 ha farmer’s field on swamp land in Gelebak Dalam Village, Rambutan sub-district, district of Banyuasin, from January to December 2017. The cultivation technology studied is the using of large number of rice seedlings which is known as Hazton system. The study was arranged on a randomized block design with a combination of varieties and number of seedlings. Varieties were used is Inpari 30, Inpari 33, Inpara 2 and Inpara 4 which tolerant to swamp area. The cultivation technologies, whereas, are consisting of Hazton 1/T1 (10-20 seedlings/hole), Hazton 2/T2 (20-30 seedlings/hole) and integrated crop management/PTT (T3). Data were observed is plant growth and yield of rice, pests attach and economic analysys. The results show that the best plant growth is Hazton T1. The number of productive tillers produced by Hazton T1 and T2 technology is higher than PTT technology, but the percentage of the formation of productive tillers is lower than PTT technology (<70% tillers were formed). Hazton technology influences the intensity of pest attacks, where the intensity of pest attacks is higher than PTT technology. The results of the study also showed that rice productivity produced in various treatments was relatively lower than the desired target, which in general rice province only reached 4 t/ha. The difference in average yield between PTT technology and Hazton is only 0.2 t. The economic analysis indicate that PTT technology is more profitable than the Hazton system, which is showed on both of B/C and R/C ratio. Keywords: hazton system, integrated crop management, paddy, swamp area, South Sumatera

Abstract

Syahri et al, 2019. Rice Farming System Based on Integrated Crop Management in Swampy Area of South Sumatera. pp. 436-441.Abiotic stress namely soil acidity and droughout are known as major problem in farming systems on swampy area. They need good agricultural practices in order to manage them, such Integrated Crop Management (IPM). One of them is rice varieties which adaptative for swampy area, such as Inpari 30, Inpari 33, Inpara 2 and Inpara 4. These varieties were cultivated on 3-ha farmer’s field in Rambutan sub-district, district of Banyuasin.  Technology was used are legowo 4:1 system, 21 days seedling, 2-3 seedling per hole and integrated pest management. Plant growth and yield were observed in this research. The result showed that ICM could increase benefit for farmer (R/C > 1) through increasing of rice yield. Productivity of Inpara 2 and Inpara 4 about 4,4 t dried grains per ha.
