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 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

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.
