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

The objective of this study was to investigate the effect of photoperiod, indole acetic acid (IAA), and phosphorus on soybean plant growth and seed quality during storage. The trial was carried out at Sebapo Experimental Station, Jambi, Center for Post Harvest Research and Development, The Ministry of Agriculture and Center for Forest Research and Development, The Ministry of Forestry, Bogor from November 2009 until June 2010. Split-split plot design was used consisted of three factors, i.e. photoperiods (12 and 14 hours 54 minutes) as the main plot, concentrations of IAA (0, 75, and 150 ppm) as subplot, and dosages of phosphorus (0, 60, and 120 kg P2O5 ha-1) as subplot. The result showed that photoperiod, IAA, and phosphorus application had significantly improved production and seed quality. The path analysis showed that the weight of 1,000 seeds affected other variables. The seed protein content has the largest path coefficient compared to other variables. The treatment of mother plant with 14 hours 54 minutes photoperiod combined with IAA of 150 ppm and P2O5 of 120 kg ha-1 resulted in the highest seed quality during 90 days of storage in room temperature.

Abstract

Seed priming has been widely used to improve seedling vigor of several crops  such as corn, wheat, and rice. Seed priming with zinc to increase seedling tolerance on submergence stress had never been evaluated. The objective of this research was to identify agronomical and physiological characteristics of several rice genotypes during seedling stage at submergence stress following zinc priming treatment. This research used factorial randomized block design with three replications. The first factor was rice genotypes and second factor was zinc solution of ZnSO4.7H2O. Seeds were soaked with Zn solution at different concentrations namely 0, 2.5, dan 5.0 mM respectively for 24 hours. After that the seeds were germinated on soil media in side the plastic box. Fourteen days-old seedling were submerged in water for 5 days and then return to normal condition for recovery. Parameters being observed included seedling dry weight, shoot carbohydrate, and leaves chlorophyl which were measured after 10 days of recovery. Seedling height was measured once a week from 2nd to 4th week. Results showed that intolerant genotypes to submergence stress grew faster but seedling dry weight, shoot carbohydrate and leaves chlorophyll content were lower compared to those tolerant genotypes. Local and national varieties which were not tolerant to submergence stress could be improved by priming treatment with 5.0mM zinc.Keywords: abiotic-stress, seeds- priming

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.

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.
