Abstract

Raharjo et al., 2000. Study of Yield Losses during Drying and Milling of Paddy in Tidal Lowland of South Sumatra. J. Lahan Suboptimal 1(1):72-82.In tidal lowland of South Sumatra low quality rice called beras batik is commonly found. Beras batik is rice that is low in both quality and prices. The low quality rice grains have high fracture, the percentage of head rice is only 25%, while the percentage of yellow grain exceeds 50%, and its selling price is only Rp. 1800/kg in 2004. The main causes were poor harvest and post harvest handling, delaying harvest and post harvest due to the lack of manpower and facilities owned by farmers. The condition was worsened by the heavy rainfall during harvest time and sometimes coincided with high tide. The study was conducted on July 2011 (dry season) in tidal lowland reclamation area of Telang Rejo village, Muara Telang Sub-district, Banyuasin Regency. In this study 2 post-harvest technologies were introduced to improve harvesting techniques and post harvest handling; (1) Drying assessment of Grain Dryer Machine Fueled withhusk, and (2) Study the Different Configurations of Rice Milling Unit. Lost during drying was 2.77 for sun drying compared to 7.13% with box dryer. Field testing at RMU 1 showed that milling recovery using box dryer (63.5%) was higher than sun drying (61.6%). But, at RMU 2 milling recovery for box dryer (61.3%) was lower than sun drying (63.7%). For milling losses, box dryer (4.99%) was lower than sun drying (5.99%).

Abstract

Suwignyo et al., 2012. Modification of Nutrient Application for the Improvement of Rice Seed Vigor in Submergence Threat. JLSO 1(1):1-11.In fresh water swamp rice cultivation, farmers  face the problem of high water levels during the early stage of plant growth, causing risky situation for seed. This study was aimed to obtain a method to increase rice seedling tolerance to submergence stress through improving fertilizer application  rice variety. The experimental design used was factorial completely randomized design with three replications. The factor consists of rice varieties (Inpara 3, Inpara 4, Inpara 5, BR 11 sub-1, IR 42, Rutti, Uffa, and Serendah Kuning), and fertilization treatment (NPK at planting without submergence; NPK with N at 7 days prior to submergence; NPK with N at one day after submergence; NPK + manure with N at 7 days prior to submergence; NPK + Manure + Si + Zn with N at 7 days prior to submergence; and NPK + Manure + Si + Zn with N at one day after submergence). The results showed that application of the proper nutrients could increase rice seedling vigor under submergence stress. At nursery stage, application of NPK, Manure, Si and Zn, with Nitrogen  after submergence would improve seedling vigor after recovery period. Submergence stress tolerant varieties showed higher ability to survive under submergence stress, and Inpara 4, Inpara 5, and BR11 Sub-1 performed better than Inpara 3. Serendah Kuning showed  better response to submergence stress than other local varieties.

Abstract

Yenni, 2012. Amelioration of Potential Sulphidic Soil for Onion Cultivation (Allium ascalonicum L.). JLSO 1(1): 40-49.Lowlands contains sulphidic soil which is  potential for crop production, yet acidic and lack of nutrients which inhibits plant growth. This study was aimed to identify the effects of liming of sulphate  soil on the growth of Onion (Allium ascalonicum L.). This study was carried out using factorial completely randomized design with six replicates on sulphate soil. The experiments were performed on poly bag (5 kg soil/poly bag/plant in acid sulphate soil. The  first factor was soil pH 4,05 (S1) and 5,02 (S2). The second factor was lime dosage(K0), 1 ton/ha (K1), 2 ton/ha (K2), and 3 ton/ha (K3). The plants were harvested after two month. Parameters measured were the growth of onion such as plant height, leaf number, bulb number, root length, fresh weight and dry weight of tuber. Secondary metabolite content of tuber was determined using gas chromatography. Data obtained werewas analyzed using ANOVAs, followed by Duncan Multiple Range Test (DMRT) with 5% significant level. Data analysis revealed that the combination of soil pH and lime dosage  has  significant effect on growth and yield of onion. Based on GC analysis, two tons/ha liming in sulphate soil gave the highest secondary metabolite contents.

Abstract

Ikhwani, 2012. The Effect of Submergence and N fertilizer Application on Plant Growth and Production of  Submerged Tolerant Rice Variety. JLSO 1(1):12-21.This study aimed at analyzing the effect of submergence and N fertilizer application on the plant growth and production of submergence tolerant rice variety. Problems and constrains of  rice production on flood prone and flash flood lowlandbecoming more frequents and more intens, causing submergence of the whole parts of rice crops for certain periods. The experiment was conducted to determine the effect of submergence and N fertilizer application on the growth of two treatment factors using block randomized design  with submergence tolerant variety Inpara 4 and 5.   An experiment was conducted in the greenhouse at Muara Experimental Station, Bogor in 2009. The treatments  consistedof three replications. The first factor was submergence rice variety Inpara 4 and 5 and the second factor was N management application, whereas (1) 200 kg Urea/ha, (2) 300 kg Urea/ha;  (3) 300 kg Ponska/ha + 100 kg Urea/ha; (4) 400 kg Ponska/ha (2x); (5) Briquette Urea  (300 kg Urea/ha) dan (6) 300 kg Urea/ha  +  Silikat (400 kg SiPPadi HS/ha).  Result of the experiment showed that   submergence for 14 to 24 DAP (10 days) on submergence tolerant rice variety combined with Briquette Urea (300 kg urea/ha  wrapped in strawpaper)  has increased the percentage of tiller number up to 98,9 percent , increased the highest total grain weight  for submergence tolerant rice  up to 41,2 gr per pot and increased in the proportion of  wet leave weight growth rate for  submersion treatment up to 1,4g per pot than that  without submergence.

Abstract

Susilawati et al., 2012. Agronomic Characteristics and Tolerance of Red Chili Varieties under Water Logging Stress during Generative Phases. JLSO 1(1):22-30.The research objective was  to evaluate the responses of growth and tolerance of red chilli under waterlogging stress during generative phases. Experiments were conducted in village   Alang-alang Lebar Palembang, South Sumatra, from April  to November 2010. Experimental design used was split plot with three replications. The main plot was waterlogging for 1, 2, 3 and 4 days. The subplot was  red chili varieties consisted of Kiyo F1, Bravo F1, Taro F1, Lembang 1, Laris, Riawan, Mario and Kusuma. The results showed that the maximum period of waterlogging  of Red chilli plants in the generative phase was three days. Increased duration of waterloggingduring the generative phase significantly decreased the ability of plants to survive, the number of live plants,  plant height and the number of branches. Based on the agronomic characteristics found in the study, the variety that is the most  tolerant to  waterlogging  during the generative phase was Kiyo F1.

Abstract

Waluyo, Alkasuma, Susilawati, Suparwoto. 2012 Spatial Inventory of Potential Competitiveness Swamp Land for Agricultural Development in South Sumatra. J. Lahan Suboptimal 1(1):64-71. Swampy marsh land has great competitive advantage for farmland development.The purposes of this study were 1)to identify the spread of potential swampy marsh land for food crops in major production centers; 2)to understand thecontent, quantity,and distribution of minerals essential for health in the low lands of South Sumatra. Data were collected through some surveys using transects (toposequen), including delineation of maps, flooding/ground water, state of the microrelief, soilbase material, land use, and land surface condition. Ground observations were based on the Soil Survey Manual. The results indicated that Sungai Pinang and Rantau Panjang has three types of swampy land, namely shallow swampy marsh, mid marsh low lands, and swamps in the low lands. Swampy marsh as the potential competitiveness for its antioxidant mineral deposit (Fe, Mn, Cu, Zn, and Se) can produce good functional food products such as Padi seputih, Pelita Rampak, Ketan Sinde, Padi Petek. These varieties have considerably high antioxidant mineral. Therefore, the use of swampyland must be directed. Shallow and intermediate wetlands can be used for rice, pulses and vegetables whereas deep wetlands are suitable for fishing.
