Effects of Different Levels of Nitrogen and Poultry Manure on Quantitative and Qualitative Chracteristics of Autumn Growing Cucumber

The effects of 4 different levels of nitrogen (0,120,150, and 180 kg nitrogen per hectare) and one level of poultry manure (10 tons per hectare) on the quantitative and qualitative characteristics of an autumn grown cultivar of cucumber [Cucumis sativus, cv.'super dominos] were studied in DarrehShahr, Ilam. The experiment was conducted in a completely randomized block design with 3 replications. The results showed that treatments affected yield, number of nods and plant fresh weight and the highest yield was 41/287 ton/ha in the plots receiving poultry manure. Also 180 kg of pure nitrogen increased yield compared to control. Effect of treatments on fruit length, diameter, and fruit dry matter was different. Plant length, number of nodes, and plant fresh weight showed a positive and significant correlation with plant yield.
