EFFECT OF ORGANIC FERTILIZERS AND MAGNETIZED WATER IN GROWTH AND YIELD OF MEDICAL PUMPKIN FROM FIXED OIL AND ITS COMPONENTS

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 organic fertilizer and magnetized water  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 levels of fertilizers are: control (without fertilization) (F1), chemical fertilization (Recommended) (F2) ,fertilization with mushrooms waste 5%(F3), 7.5% (F4), fertilization with poultry manure 5% (F5), 7.5% (F6). 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 significant increase in plant height at treatments F6 and F4 with A2 in the open field and with A1 in green house (365.1, 312.3, 597.9, 504.9 cm respectively). Reached   highest number of branches and dry weight at treatment F6 with A2, leaf area with A1 of  open field, (3.2 branch .plant^-1 , 113 dsm² 152.1 g respectively) and the highest increase in the leaf area and dry weight at treatment F4 with A1 of  green house (498.5 dsm² , 273.5 g respectively). Highest yield of  the fruits was at treatment F2 with A1 and F6 with A2  in open field(40.0, 33.5 ton .h^-1 respectively) and treatment F5 with A1in green house (29.7 ton .h^-1). Happened  highest yield of seeds at treatment F6 and F4 with A1  in open field(240.4, 231.8 kg .h^-1 respectively) and at treatment  F2 with A1 in green house (401.2 kg .h^-1) also a higher yield of oil at  F4 and F6 with A1  in open field(58.1, 55.8 kg.h^-1 respectively) and  at treatments F5, F4 with A1 in green house (142.1, 139.7 kg.h^-1 respectively) Reached highest percentage of oleic  acid at F1 with A2  in green house (17.0%) while reached  higher percentage of linoleic acid at treatment F4 , F2 with A1 (68.3, 68.1% respectively) and the higher percentage of phytosterols at treatments F3 with A2 in open field (1.9%) and the treatment of F1 with A2 in green house (2.3%).
