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

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.

Safriyani E, Hasmeda M, Munandar M, Sulaiman F, Holidi H. 2019. Pests and weeds controlling using integrated rice-duck-azolla farming. In: Herlinda S et al. (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
