Abstract

Background and objectives: Pumpkin is one the most important cultivated medicinal plants, because of high quality oil and its uses as edible and herbal medicine. A high oil production of pumpkin by lower amounts of chemical fertilizers is one of the important aims for researchers in agriculture.Materials and methods: To find out the effects of different rates of pelleted animal manure and urea and some micronutrients on the morphophysiological characteristics and OIL YIELD of pumpkin, a split plot experiment based on randomized complete block design with three replicates was conducted at the Research Farm of Abouraihan Campus, University of Tehran during 2010-2011 growing season. The pelleted animal manure and urea with four levels (150 kg urea, 50 kg urea+3.5 tone animal manure, 100 kg urea+1.5 tone animal manure and 150 kg urea+1.5 tone animal manure) were considered as the main plots and micronutrients with three levels (1000, 2000 and 3000 (mg Kg-1); including iron, zinc, manganese from a chelate source and boron from boric acid source) were considered as sub plots.Results: Results showed main factor had significant effect on plant height, branches number, female flowers, and OIL YIELD (p£0.01) but main factor had no significant effect on SEED OIL PERCENTAGE. Mean comparison test showed that the highest plant length (329.6 cm), branches number (15.1), female flowers number (5.2), FRUIT NUMBER OF PLANT (2.1) and OIL YIELD (481.8 Kg h-1) was obtained by applying 150 Kg urea+1.5 tone animal manure as pelleted. Also most SEED OIL PERCENTAGE up to 45.1% obtained by 150 Kg urea application. The highest number of female flower (5.14), SEED OIL PERCENTAGE (46.5%) and OIL YIELD (431.6 kg.h-1) was obtained by 2000 mg Kg-1 of microelements, but this treatment had no effects on other parameters. Variation of SPAD showed applying pelleted animal manure and urea and 2000 mg Kg-1 micronutrients was more effective on chlorophyll content. Improving these characteristics were related to positive effect of integrated application of manure and chemical fertilizer on plant nutrition and gradual releasing of nitrogen from pelleted animal manure. Also results showed that high amount of micronutrient application could have negative effect on morpho-physiological characteristics and yield of Pumpkin.Conclusion: In general, results showed that applying 150Kg Urea+1.5 tone plleted animal manure with 2000 (mg Kg-1) of micronutrients could be suggested as the best option for achievement of the best morpho-physiologial characteristics and OIL YIELD of pumpkin.
