Abstract

Human interest in soybean greatly increased in recent years due to the positive effects of secondary metabolites in soybean such as isoflavones for human health. Isoflavones are phytoestrogens worked as the antioxidant and chemopreventive agents for estrogenic compounds that can inhibit cellproliferation. Isoflavones also serves to prevent heart damage, osteoporosis and menopause syndrome, prevent prostate cancer, colon cancer and breast cancer. Daidzein, genistein and glycitein are the major isoflavones in soybean. A research about isoflavone charácters of three soybean varieties under droughtstress with application of Nitrogen sources was conducted in green house, Faculty of Agriculture, University of Sumatera Utara. The aim of the research was to study the effect of Nitrogen sources under drought stress on isoflavone characters of three soybean varieties. The experiment used a Factorial  andomized Block Design with three factors and three replications. The first factor was soybean varieties consisted of Anjasmoro, Wilis and Sinabung. The second factor was Nitrogen sources consisted of without N fertilizer application; Urea 50 kg/ha, Bradyrhizobium sp., cow manure 10 t/ha, rice straw compost 10 t/ha. The third factor was soil water content condition namely 50%, 60%, 70 and 80% of field capacity. The parameters observed were isoflavone charcters consisted of genistein, daidzein, glycitein and isoflavone total. The resultshowed that Anjasmoro variety had the genistein, daidzein, glycitein and isoflavone total contents of soybean higher than Wilis and Sinabung. The application of Nitrogen sources increased the genistein, daidzein, glycitein and isoflavone total contents of soybean compared without application of Nitrogensources. There is a distinct pattern in the increase in the isoflavone total content in Anjasmoro, Wilis and Sinabung with increasing the drought stress. At Anjasmoro variety, increasing drought stress caused the elower of isoflavone total content, while the varieties Sinabung and Wilis are the opposite pattern

Abstract

Soybean  is  a  legume  sensitive  to  drought  conditions  resulting  in  decreased  yield  and  seed quality.  Drought stress on plants also inhibits nitrogen uptake.  The objective of the research was to  determine production and physiological characters  of soybean varieties under drought stress through nutrient N management. This research used a randomized block design with  3 factors  and  3  replications.  The  first  factor  was  soybean  varieties  (Anjasmoro,  Wilis  and Sinabung). The second factor was drought stress conditions consisted of 50%, 60% , 70% and 80%   of field capacity (FC). The third factor was the application of N consisted of (1). Without application of N fertilizer (control);  (2). N fertilizer dose of recommendation (50 kg Urea/ha); (3). Inoculation of Bradyrhizobium sp. ; (4). Organic N sources (straw compost 10 tons/ha)  ; (5).  Organic  N  sources  (farmyard  manure  10  tons/ha).  The  results  suggest  that  Anjasmoro variety  improved dry weight of seed per plant compared with Willis and Sinabung.   Increased drought stress ( 80-50 % of FC) resulted in a decrease in dry weight of seed per plant. Sources  of  N  in  the  form  of  urea  or  Bradyrhizobium  sp.  increased  the  dry  weight  of  seeds  per  plant compared  with  treatment  N  sources  straw  and  manure  compost.  The  interaction  between Bradyrhizobium sp.  or Urea and Anjasmoro variety improved  dry  weight of seeds per plant

Abstract

Basal stem rot (BSR) caused by Ganoderma is an important disease of oil palm in North Sumatra, Indonesia. Control of BSR is complex, because the disease occurs in the dynamic environment at the interface of the roots with soil. Compost with endophytic fungi as a biological fertilizer offer possible advantages and eventually suppressed ganoderma growth. A study using two compost oil palm (empty fruit bunch and palm oil midrib-leaf compost) containing indigenous endophytic fungi (Trichoderma koningii, T. viride, and Aspergillus sp.) singly and in a mixture was conducted to determine potential of them to control Ganoderma. The result showed that 16 weeks after artificial inoculation, all treatments aren't significant difference reduced BSR incidence but compost containing endophytic fungi have potential to inhibit the pathogen showed BSR incidence in a mixture treated lower than singly treated seedlings

Abstract

This study was aimed at assessing effects of mulch on soil temperature, physical properties of soil, and growth of patchouli. The experiment was conducted in Village ReuleutTimu, Sub District MuaraBatu, District Aceh Utara, from June to September 2013. The experiment was arranged in a randomized block design with three replicates. Types of mulching consisted of five levels i.e. without mulching, rice straw spread 10 tons ha-1, rice straw mulch spread 5 ton ha-1 + embedded 5 ton ha-1, sawdust spread 10 tons ha-1, sawdust spread 5 ton ha-1 + embedded 5 ton ha-1.The variables observed were soil temperature, bulk density, C-organic, N-total, C/N ratio, porosity of the soil, plant height, number of branches, leaf area, and dry weight of plants. Results showed that mulching resulted in lowering temperature, value of bulkdensity, and ratio of C/N soil, andincreasing levels of N-total, and improving soil porosity.  Mulching also affected plant height, number of branches, leaf area, and plant dry weight. Rice straw provided lower degree of soil temperatures than sawdust, but did not provide better of plant height, number of leaves, leaf area and dry weight of plants. Spread rice straw provided lower soil temperature and better leaf area at 60 day after planting but lesser dry weight at 75 day after plantingthan spread+embedded rice straw.
