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.

Abstract

The dissemination of new varieties produced Agricultural Research are usually constrained by farmer preference at the farm level. The level of preferences determined the admissibility of a high-yielding varieties those were introduced. The study of preference was conducted in Lubuk Sakti village, Indralaya District, Ogan Ilir Regency, South Sumatra from April until August 2013. The location is the location of the demonstration plot studies testing new varieties (VUB) Agricultural Research results. Preference test conducted on rice and rice from Ciherang, Inpari 10, Inpari Inpari 12 and 14. Respondents consisted of 20 farmers who are members of farmer groups Rays Way. Parameter assessment consists of rice appearance, color and aroma while the rice is composed of taste, color, texture and aroma. As for the scale for the assessment of rice and rice namely: (1) Very dislike, (2) Dislike, (3) Somewhat Like, (4) Like and (5) Very Like it. The results showed that Inpari 10, Inpari 14 and Ciherang has the potential to be developed in the swampy marsh areas have a preference for rice and rice were good enough that somewhatlike to like. Most farmers in the swampy wetlands preferred rice varieties have furnished (rice fluffier texture).

Abstract

Indonensian Agency for Agricultural Research and Development (IAARD) has issued some fertilization recommendations, such as fertilization based on Soil Test Kit for Low Land Rice (PUTS) and Planting Calendar (PC). The reasearch aimed to introduce and examine the effects of various fertilizer recommendations, especially on low land. The research was conducted in Lubuk Sakti village, Indralaya sub-district, Ogan Ilir district from April to Agustus 2013. The research was arranged in 3 treatments fertilization based on PUTS,  PC and farmer practice (control). The rice varieties used Inpari 12. Legowo plating system was applied by 4:1 (plant spacing 25 x 50 x 12.5 cm) and farmers practice (plant spacing 25 x 25 cm). The plot size was 13 m x 27.5 m. The results showed that both of fertilizer recommendations issued by IAARD were able to increase rice productivity than control.  STK, PC and control with the yield 5.60 t/ha, 6.56 t/ha and 5,20 t/ha, respectively. Fertilizer recommendations also reduced rice pests and diseases.

Abstract

The demand of corn continues to increase along with the increasing of populations and industries. Compliance efforts could be done by increasing productivity through extensification and intensification farming. Statistical data showed that corn harvested area and production in South Sumatra over the period 2000-2012 was very volatile but had a tendency to increase since 2006. The area of ??land suitable for development of corn in South Sumatra, which amounted to 898,877 ha. This area consists of the intensification of land (205,709 ha), extensification of land (159,444 ha) and the diversification of land (533,724 ha). Land use for corn so far has been done in some districts/cities having dry land like Ogan Komering Ulu (OKU), OKU Timur, Ogan Ilir, Ogan Komering Ilir well as in several districts that have ups and downs like agro Banyuasin and Musi Banyuasin. South Sumatra AIAT demonstration plots showed that significant productivity of corn. In 2010, IPM demplot of Mulyasari village, sub district of Tanjung Lago, District of Banyuasin showed that productivity of Bima 4 (8.8 t/ha), Bima 5 (8.3 t/ha), and Bisi 2 (8.4 t/ha), whereas in 2011 Banyuurip demplot showed that productivity of Bima 3 (11.27 t/ha) and Sukmaraga (8.13 t/ha).

Abstract

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
