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.

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.

Abstract

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
