Abstract

Bulbs  of    localSamosir  Shallot  with  the  weight  ranging  from  1,3  to1,7  g  were  irradiated  by  several doses of gamma rays in order to investigate the radiosensitivity and the effects of irradiatons on the plants. Dry bulbs 2,5 months after harvest were exposed to gamma raysradiation ranging from 0 Gy to  20  Gy  to  determine  their  responses  to  radiation  stress  and  the  effective  radiation  dose  for identification of Lethal dose 50 (LD50). Percentage of shoot growth was measured on 35th days after planting. The variation in morphological and agronomic characters were also determined.  The results indicated  that  increasing  doses  of  gamma  irradiation  had  significant  effect  on  shoot  growth. Increasing  in  gamma  rays  doses  from  0  Gy  to  11Gy  had  little  effect  on  percentage  of  shoot growth.With  the  increase  in  radiation  dosesabove  11Gy,  agreat  reduction  in  percentage  of  shoot growth  was  observed  in  irradiated  bulbs  as  compared  to  control.  The  LD50  values  of  local  Samosir Shallot  determined  from  linear  regression  analysis  (using  Curve-fit  Analysis    software)  based  on percentage  of  regenerated  shoot  growth  was  11.60  Gy.  There  were  also siqnificantdifferenciesbetweenregenerated  plants  growth  from  irradiated  bulbs  and  control (unirradiated).Treated bulbs produced shorther plant lenght and less leave number

Abstract

The Growth and Yield of Shallot (Allium ascalonicum L.) according to Application of Vermicompost and Sheep Urine. Application of inorganic chemical fertilizers continuously without the use of organic fertilizers  has caused the degradation of agricultural land. The negative impacts caused by land degradation is a decline in agricultural yield, such as the yield of shallot. A solution to solve this problem is to replace the application of chemical fertilizers that can damage the soil into organic fertilizers that is safe for the environment. Research was conducted to determine the response of vermicompost and sheep urine to the growth and yield of shallot at Fakultas Pertanian USU’s Green House with a height of 25 m above sea level on April-June 2012 using randomized block design of two factors, the factors were  vermicompost (0;15;35;45g/plant) and sheep urine (0;200;400 cc/l water). The parameters observed were plant height, tillers number, leaf number, wet weight per sample,wet weight per plot, dry weight per sample, dry weight per plot and clove number. The results showed that interaction of vermicompost and sheep urine treatment significantly influenced the plant height. Vermicompost treatment significantly influenced the tiller number and leaf number. Sheep urine treatment significantly influenced the leaf number, wet weight per sample and dry weight per plot. Key words : shallot, land degradation, vermicompost, sheep urine     ABSTRAK Pertumbuhan dan Produksi Bawang Merah (Allium ascalonicum L.) dengan Pemberian Vermikompos dan Urine Domba.
