<![CDATA[Susilawati et a, 2017. Technology Development for Sustainable Tidal Swamp Land Management. JLSO 6(1):87-94.Tidal land is very potential to be developed as food gardens and agriculture of the future of Indonesia considering (1) productivity is still low, (2) potential land is still wide, (3) indices of plantation (IP) is still low, (4) degraded land potential , (5) the pattern of food production in tidal land is complementary to the pattern of food production in Java, (6) the competition for land use for non-agricultural purposes is relatively low, and (7) the availability of production technology of various commodities. Tidal land is an area whose water availability is affected by the movement of water on the surface of the river due to the movement of the moon, the land is included in the sub-optimal land category, ie the land that has many problems and needs to be overcome in order to provide benefits. The problems are water problems and soil chemical characteristics that have not provided maximum support for agricultural cultivation system. Therefore, priority should be given to technological development that is technically relevant to the characteristics of the land, economically affordable to local farmers, and expected to be in tune with the preferences and socio-cultural of local communities. Two approaches that can be parallel and interactively carried out are [1] optimizing the physical, chemical, and (micro) properties of soil biology along with optimizing the management of water resources to be eff ective and more efficient; and [2] appropriate selection of commodity types and development of adaptively specific varieties for each suboptimal land characteristic.]]>

<![CDATA[Nurhasanah et al, 2017. Response Rice Mutant Insertion Growth in the Low Nitrogen Conditions. JLSO 6(1):49-58.Nitrogen is an essential fertilizer for growing rice because N needed higher than other nutrients. Therefore, many farmers apply a large amount of nitrogen fertilizer to obtain high production. Unfortunately, the plant not utilized much and only 50-60 % of the total N was applied which able to used. It would be lost through a combination of leaching, surface run-off, denitrification, volatilization and microbial consumption. Thus, the large amount N fertilizer application increase input cost and damage the environment. To build sustainable agriculture, the screening of varieties or mutant which is capable of using N efficiently is necessary. In addition, knowledge of N regulation and mechanisms in plants needs to be exploited for efficient plant development in the use of N. This study aims to look at the response of mutant rice plants in the low N conditions and obtain mutant rice plant candidates which is efficiently in using N. Seventen mutan insertion and Niponbare as wildtype are used in this experiment. Rice mutant plants were grown hydroponically inYoshida solution with different N concentration. Under normal conditions the N concentration was 1.14 mM/L and in the low N concentration was about 0.114 mM./L. Parameters was measured in this study were plant height, root length and dry weight. The results showed that plant height mutant insertion wasnot influenced by N concentration in nutrient solution. Meanwhile root lenght and dry weight plant parameter are affected by N consentration. There are mutant insertion plant that have potential and the optimum growth ability at low N concentration, especially B101. Validation on that mutants will be done in the next research.]]>

<![CDATA[Nafisah et al, 2017. Grain Yield of Rice Elite Lines Under Saline Prone Condition in Cilamaya Wetan, Karawang Subdistrict West Java. JLSO 6(1):21-32.Utilization of high yielding rice varieties tolerant to salinity is one way to maintain yield sustainability in salt affected rice area. As many as 30 elit lines and 4 varieties checks were tested in saline prone area in Muara Baru, Cilamaya Wetan sub district, Karawang, West Java. The trial was arranged in Randomized Block Design with three replications. Twenty eight old seedlings were planted in 3x4 m2 plot size with 25 cm x 25 cm planting space. Analysis variance showed two elit lines (1131-Ski-4 dan IR86385-50-2-1-B-SKI-2) yielded 5.48 dan 5.64 t/ha, respectively. These yield were significant higher than those of two popular checks planted by local farmers, i.e. Mekongga and Sintanur which yielded about 4,44 t/ha. Beside 11 lines had yield 0,5 t/ha higher than that of popular check variety.  Correlation analysis showed grain yield highly positive correlated with productive tiller number and filled grain number, while thousand grain weight highly positive correlated with plant height. Screening for salinity tolerance in seedling stage done in screen house showed that both 1131-Ski-4 dan BP14082-2b-2-5-TRT-35-2-SKI-1 consistently tolerant under salinized Yoshida solution at 12 dSm-1. These two lines are very potential for further tested in saline prone area.  ]]>
