Abstract

Decreased rice productivity due to high iron concentrations especially in the vegetative phase, this causes the morphological character of rice to be affected until the metabolic process is disrupted. This study used 6 varieties, namely Batu Tegi, Inpara 9, Situ Patenggang, Inpara 8, Hawarabunar and Inpago 8, with iron concentrations of 0 and 250 ppm. The seeds were germinated for 3 days, then planted in Kimura B 10% nutrient culture media for 9 days, for 2 weeks then each week the media was changed to 100% Kimura B solution with the addition of 250 ppm iron concentration which was sampled every week until the 35th day. The results of the analysis of variance of the variables of plant height and root length showed that the combination Inpara 8-01 was the best combination and had a significant effect compared to other combinations with an average value of 61.31 cm and 30.77 cm. In the variable number of leaves the best average value was found in the combination of Batu Tegi-01 and Inpara 9-01 which had a significant effect compared to other treatments with an average value of 5.87 strands and 9.60 strands, respectively. On the stem dry weight variable, the combination of Hawarabunar-250 ppm Fe had a significant effect on other treatment combinations with the highest value of 0.17 g and the lowest value of treatment combination Inpara 9-250 ppm with a value of 0.08 g. Based on the results of treatment with 250 ppm Fe stress on plant morphological characters, the Hawarabunar variety had the best response in tolerating Fe stress, while the Batu Tegi variety was the lowest in tolerating Fe stress.

Abstract

The research objective was to study the agronomic and physiological characteristics of red chilli (Capsicum annuumL.) varieties under waterlogging stress. These studies were conducted at two locations: in Palembang, South Sumatra, from February to August 2010 and in Bogor in West Java, from September to November 2010. Experiments in Palembang was using split plot design with three replications. The main plot was waterlogging treatment for 1, 2, 3 and 4 days. The subplot was red chilli varieties: Kiyo F1, Riawan, Ferosa, Bravo F1 and Laris. Experiments in Bogor was conducted without the use of experimental design; the same plant varieties were waterlogged for 2 and 4 days. The results showed that waterlogging caused root damages on all varieties. Kiyo F1 had better agronomic characters and high levels of tolerance than other varieties. The content of ethylene in all varieties increased with increasing time of waterlogging, except for Laris. In all varieties both leaf chlorophyll and tissue N content tend to decline with the increase in waterlogging duration. However Bravo F1 experienced an increase in the chlorophyll content whereas Kiyo F1 had an increase in N in the plant tissue. Keywords: agronomic character, physiological character, red chili, waterlogging

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

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.

Abstract

Elephant grass (Pannisetum purpureum) can grow in various types of land conditions and produces and is resistant to environmental stress. The predominant sand tin tailing conditions and poor nutrients cause limited plant growth above them. This research tested some kind of fertilizer treatment on sand tailing media after tin addition by using elephant grass plants. The results showed that the type of fertilizer had significant effect on the specific leaf area variant, the ratio of leaf area and the leaf weight ratio. Overall growth were greatly depressed on the 100% tailings treatment. Lime applied in conjunction with NPK fertilizer was not show the total leaf weight that was different from the addition of NPK alone. NPK fertilizers better influence the growth of elephant leaves in tin tailings than organic fertilizers. The best treatment was obtained on organic fertilization with NPK inorganic fertilization. The association of total dry weight of elephant grass with specific area of elephant grass leaf was only visible in organic fertilization treatment together with NPK inorganic fertilizer. In the best condition of elephant grass growth, the specific leaf area had a significant role to increase the total weight of the plant with the value of r2 = 0.864 or LDS will affect the total dry weight of elephant grass in the tailings medium with the addition of organic and inorganic materials NPK of 86.4 percent the remaining 13.6% increase in total dry weight was influenced by factors other than specific leaf area.
