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

Halimi et al. 2012.Â In-situ Evaluation of Growth Rate and Yield Components of Â 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 Â 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 accessionsÂ inÂ non-tidal swamp area. Research plots were preparedÂ by local farmers to include Â 27 plots of 280 cm x 80 cm following the Complete Â Randomized Block Design.Â 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.Â Each group has different growth rate according to the field water level during flooding season of < 5 cm, 5 to 6 cm, and >6 cmÂ per week, respectively. The LGRA group consisted ofÂ Petek (A5) and Senia (A6), the IGRA group consisted of Bone (A1), Pelita Rampak (A2), and SawoÂ 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.

Safriyaniet al, 2018. Correlation of Growth and Product Components on Integrated farming Padi-Azolla. JLSO 7(1):59-65.In order to increase the growth and production of rice plants that support sustainable agriculture can be done with the azolla application. This study aimed to evaluate the correlation of the components of growth and yield on rice-azolla production. The research was conducted on Karang Ketuan Subdistrict South Lubuklinggau II Subdistrict Lubuklinggau City from January to April 2018. This study used a randomized block consisting of K1=250 kg urea ha-1 without azolla, K2=250 kg urea ha-1+azolla 1000 kg ha-1, K3=187.5 kg urea ha-1+azolla 1000 kg ha-1, K4=125 kg urea ha-1+azolla 1000 kg ha-1, K5=62.5 kg urea ha-1+azolla1000 kg ha-1, K6=without Urea+azolla1000 kg ha-1. Data analysis used correlation and path analysis. The results showed that plant height and number of pithy grains correlated on grain weight with higher values than other growth components. Dry weight of straw and harvest index had a direct and positive effect on grain weight with cross coefficients value namely 1.086 and 0.755 representatives. Plant height and number of pithy grains could be used as an indicator of crop production.

Gustiar F, Munandar M, Aprilia NR, Hasmeda M, Amar M, Arsi A. 2021. Growth and Yield of Spinach (Amaranthus sp) in various compositions of Alternative Nutrients to replace AB Mix with Hydroponic System. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 931-940 . Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). The high cost of AB Mix hydroponic nutrients, so there is a need for alternative growth nutrients that are cheaper and easily available. Aim of this research was to determine the hydroponic nutrition substitute for AB mix for the growth of spinach (Amaranthus sp). This study used a completely randomized design (CRD) method with four hydroponic nutrition treatments with different ingredients. The treatments given were AB mix fertilizer, NPK-based nutrition, single fertilizer-based nutrition, and organic nutrients. hydroponic nutrient constituents are calculated based on the needs of leaf vegetable plants. Needs Parameters observed were plant height (cm), number of leaves, leaf greenery level, leaf area (cm2), root volume (ml3), plant fresh weight (g), plant dry weight (g), and nitrogen concentration (N) at leaf. Based on the observation of growth parameters, AB mix nutrition treatment showed the best results. However, the fresh weight parameter of the single fertilizer-based nutrient treatment showed results that were not significantly different from the ABmix treatment. In addition to providing the highest yield, the lowest cost requirement is 1 liter of concentrate at a cost of 44,302 IDR so that single fertilizer-based hydroponic nutrients can be recommended as an alternative to AB Mix nutrition.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 71-78. Palembang: Unsri Press.Pests and weeds can reduce plant growth and production. Integrated Rice-duck-azolla farming is biologically controller of pests and weeds in rice plants. The research aims to evaluate the role of ducks and azollas in reducing pest and weed populations of rice plants. The research has been carried out in the irrigated rice fields of Tanah Periuk Village, Muara Beliti District, Musi Rawas Regency from October 2018 to February 2019. The study used experimental method with a randomized block design, consisting of K1= 250 kg urea/ha: without ducks and azolla, K2 = 187.5 kg urea/ha: without ducks: azolla 1000 kg/ha, K3 = 187.5 kg urea/ha: duck 3000/ha: azolla 1000 kg/ha, K4 = 125 kg urea/ha: duck 3000/ha: azolla 1000 kg/ha, K5 = 62.5 kg urea/ha: duck 3000/ha: azolla 1000 kg/ha, K6 = without N: duck 3000/ha: azolla 1000 kg/ha. The application of 3000 ducks/ha and 1000 kg/ha azolla could reduce rice pests and weeds, including Nephotettix virescens 83.33%, Valanga SP 88.70% dan Scirpophaga innotata 83.57%, Fimbristylis dichotoma 84%, Cyperus difformis 91.4%, Ludwigia adscendens 85.7% and Eclipta prostrata 80.8%.Keywords: azolla, duck, integrated farming, pest
