Abstract
A field experiment was carried out at the Experimental Field of Hort. Dept/ College of  Agric .Abu-Ghraib/University of Baghdad during the spring growth season and autumn of 2013, to study  effect gamma rays and the magnetization on Growth and production of medicinal pumpkin from fixed oil and its components, the experiment included two factors, First was irrigation with normal water(A1), irrigation with magnetized water 500 gauss(A2) and the second factor included six types of physical treatments which were: control (B1), the magnetization of seeds with 2500 gauss (B2), 3500 gauss (B3), irradiation of seeds with 20 Gray rad (B4), 40 Gray rad (B5),and 60 Gray rad (B6). The experiment was implemented within Nested design and three replications for spring season (open field) and autumn season (green house). The results showed that the highest significant increase in leaf area was at treatments of B6, B5, B4  with A1in the open field (170.8,164.7,160. dsm2 respectively), while the highest leaf area at  treatment of B6 , B3 with A1 in green house (274.6,273.5 dsm2 respectively). Highest dry weight was at treatments B6 , B4 with A1 in the open field (203.9, 183.3 g respectively), and at treatment of  B3  with A1 in green house (215.8 g). Higher yield of fruits, seeds and oil has reached at  treatment of B4 with A1 in open field (79.9 t/ha, 568.6 kg/ha, 108.8 kg/h respectively) and at treatment of  B5  in green house with A1(31.0 tons/ha, 366.9 kg/ha, 112.2 kg/h respectively). Reached highest percentage of  oleic acid at  B3 with A1 in open field and B5 with  A2 in green house (58.3, 18.4% respectively), and the highest percentage of  linoleic acid at  B2 with A2 in open field(32.9%), while sterols have reached the highest rate at treatment B6 with  A2 in open field(2.13%) and at the treatment of B2 with A2 in green house(1.9%).
