Evaluation of different levels of pelleted manure and urea and micro elements on growth and physiological indices of medicinal pumpkin (Cucurbita pepo var styriaca)

To find out the effects of Urea and animal manure as pellet and some microelements on total dry matter and physiological indices of medicinal pumpkin a split plot experimental design based on a randomized complete block with three replicates was conducted at University of Tehran, college of Abouraihan. The animal manure and Urea as pellet with four levels (150 Kg Urea, 50 Kg Urea.5 tone animal manure, 100 Kg Urea.5 tone animal manure and 150 Kg Urea.5 tone animal manure) as main factor and microelements with three levels (1000, 2000 and 3000 ppm) including Iron, Zinc, Manganese in chelate form and Boron in Boric Acid form as minor factor were considered. The results showed that use of pelleted manure and urea after 30 days had significant effect on total dry matter (p
