Effect of chelate iron and method of addition on the chemical properties of two hybrids of cucumber) Cucumiss Sativus L.) Cultivated in unheated greenhouses

Maysoon M Kadim, Naba A Abdul Razzaq


The experiment was conducted in the winter agricultural season 2020-2021 in one of the unheated greenhouses at the Agricultural Research Station of the College of Agriculture- University of Basra, in order to study the effect of several concentrations of chelate iron and two methods of addition (spraying and watering) on the chemical properties of the two hybrids Super Fairs and Sayff of cucumber plant. The experiment included 12 factorial treatments, which are the possible combinations of three concentrations of chelate iron (0, 150 and 300) mg l-1 and two methods of addition (spraying and watering) and the two hybrids Super Faris and Sayff from cucumber plant, It was carried out as a split-factor experiment for one and two times, Split Split- Plot Design, according to Randomized Complete Block Design (R.C.B.D) and with three replications for each treatment. The arithmetic means of the transactions were compared using the L.S.D test at the significance level of 0.05. The most important results are summarized as follows: Sayff hybrid and the method of addition to watering were significantly superior in all the studied chemical characteristics, as the results showed that the concentrations 150 and 300 mg L-1 of chelate iron in the leaves content of total soluble carbohydrates and the percentage of each of nitrogen, phosphorous and potassium. The concentration also exceeded 300 mg L-1. Significantly in the leaves content of total chlorophyll. Binary and triple interactions were significant for the most studied chemical properties
