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

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

Halimi et al. 2012. In-situ Evaluation of Growth Rate and Yield Components of  Several Non-tidal Swamp Rice Accessions in South Sumatera. JLSO 1(2):107-115Rapid increase of agricultural land conversion has led to the intensified utilization of  non-tidal swamp. The objective of this research was to identify growth rate and yield components of several rice accessions of non-tidal lowland swamp of South Sumatera. This research incorporated the cultivation of nine rice accessions  in  non-tidal swamp area. Research plots were prepared  by local farmers to include  27 plots of 280 cm x 80 cm following the Complete  Randomized Block Design.  Research indicated that rice accessions might be classified into 3 groups of Low Growth Rate (LGRA), Intermediate Growth Rate (IGRA), and High Growth Rate (HGRA) accessions.  Each group has different growth rate according to the field water level during flooding season of < 5 cm, 5 to 6 cm, and >6 cm  per week, respectively. The LGRA group consisted of  Petek (A5) and Senia (A6), the IGRA group consisted of Bone (A1), Pelita Rampak (A2), and Sawo Rimbo (A7) and the HGRA group consisted of Kuning (A3), Siam (A4), Sawah Beling (A8) and Putih Olak (A9). Some yield components tended to decrease as the growth rate increased, and some varied depending on the accessions. For effective and efficient cultivation, farmers should apparently consider growth rate and yield potential to decide which rice accessions to grow.

Abstract

The research has been conducted at rainfield lowland of non tidal swamp in Kecamatan Rambutan Kabupaten Banyuasin in March to May 2014. Objection of research was to find the treatment for seed of rice before planting with application of Zn and nitrogen fertilizer. This factorial experiment was set by randomized block design with three replications. First factor was 6 rice varieties, second factor is two levels of Zn treatment (0 mM and 5,0 mM), and third factor is two level of N fertilizer (30 and 60 kg/ha). The 15-day seedlings, were submerged for 5 days. The parameters, dry weight of seedling, carbohydrate of stem, and chlorophyll of leaf, were measured on 10 days after submergence treatment. Carbohydrate and chlorophyll was measured according to the methode of Yoshida et al. (1976). Result of research showed that application of Zn and N increased dry weight, carbohydrate, and chlorophyll of seedling. Therefore rice seedling will be more tolerant in submergence stress.
