      Some references to some detailed work
      on Bunium persicum (Black Caraway).

      Survey on the treatment of the seed amount, the transplanting time of
      Black zira
      ( Bunium persicum ) bulbs from nursery to field with the best
      cultivation pattern.
      Mahdi Faravani (Iran ) email: faravani@...
      The present study was conducted at Khorassan Agricultural Research
      Center in order to determine the amount of seeds in nursery and the
      best transplanting date for black zira ( Bunium persicum ) bulbs from
      nursery to field and also to find out the best cultivation pattern in
      the field. Treatments consisted of six seed rates ( 20,60,100,180 and
      220 kg/ha) which were sown on November, 1996. Results revealed that 60
      kg/ha was the best seed rate to produce bulbs of two years old with
      highest weight (1.98 gr). In 1999, the experiment was laid out in
      factorial under a randomized complete block design . The factor of the
      cultivation patterns were included of three levels as square , lozenge
      and rectangle. The transplanting date of two years old black zira bulbs
      from nursery to field was conducted in three seasons (summer, fall and
      winter) in the form of RCBD. The distance between rows was considered in
      both the rectangular pattern and lozenge 25 cm and in the square pattern
      12.24 cm. The results showed that the best transplanting date of the
      black zira bulbs was summer due to bulb dormancy and considering optimum
      yield and biological yield.

      The effect of different plant density and plant rates on yield on
      Saffron (Crocus sativus) and Black Zira (Bunium persicum) in
      intercropping system.
      Mahdi. Faravani, A.R. Beheshti, M. Bazoobandi

      The effect of different plant densities and rates on saffron (Crocus
      sativus ) and black zira (Bunium persicum) intercropping was studied
      in 2000 at Toragh Agricultural Research Station in Mashhad. The
      experimental design was an randomized complete blocks in factorial
      arrangement with 4 replications and 15 treatment including 3 levels of
      plant populations (50, 25 and 12.5 plant per m2 ) and 5 level of two
      crops ration (0, 33:67, 50:50, 67:33, 100) in an intercropped
      arrangement bused on replacement series techniques. The method of
      bivariate analysis was the good methods of analysis and it make analyze
      simultaneously two values obtained from one plot related to a specific
      treatment. Evaluation of land Equivalent Ratio (LER) by bivariate method
      showed that the yield of all intercropped in treatment, LER was higher
      than 1. Decreasing density from 16.7 to 4.17 plants per m2 decreased the
      yield of black zira, But the yield of saffron wasn’t significantly
      changed. Maximum LER obtained with 33:67 saffron to black zira and plant
      density of 50 plants per m2.

      Determining optimum plant density of Black zira (Bunium persicum) in
      nursery and field

      The study was conducted during 1996-1999 at the farm of Khorassan
      Agricultural Research Center. The experiment was laied out a Randomized
      Complete Block Design with replication of four to determine optimum
      Black zira (Bunium persicum) density in nursery and field. Treatments
      consisted of six seed rates ( 20,60,100,180 and 220 kg/ha) which were
      sown on November ,1996. Results revealed that 60 kg/ha is the best seed
      rate to produce two years old bulbs with highest weight (1.98 gr). Two
      year old bulbs were sorted into three sizes (small, medium and large)
      then they were sown at 5 different densities ( 40,50,66.7 , 100 and 200
      bulbs m2 in 25 cm row spacing in the second year. Collected data during
      two year experiment were analyzed using split-plot in time design.Both
      plant density significantly affected seed yield and biological yield
      while no significant effect was observed in case of test weight, plant
      height, and umbrel number per plant and number of seed per umbrellet.
      Maximum seed yield 604.1 gram was registered in plot with 200 plants per
      meter square .Quantitative value of plant height, number of umbrella
      and as a result, seed yield and biological yield were increased in
      second year where bulb weight was more than 2 grams.
