Abstract:
نفذت تجربة حقلية في محطة ابحاث محاصيل الغالبية /محافظة ديالى في الموسم الخريفي 2013في تربة ذات نسجة طينية غرينية بهدف معرفة تاثير التغذية الورقية بالبوتاسيوم والحديد المخلبي في نمو وحاصل الذرة الصفراءL.) Zea mays (صنف بحوث 106 تحت نظام الري بالتنقيط بتصمي | A field experiment was conducted during autumn season 2013 in silty clay soil at Field Crops Researchs Station in AL - Ghalbiea/ Diyala Governorate.The aim of this experiment to study effect of foliar nutrition of potassium and chelated iron in growth and yield of maize(Zea mays L.) Buhooth 106 under drip irrigation system.Random Complete Block Design (RCBD) was used in this study with three replications. Spraying four concentrations of potassium(0, 1000, 2000, 3000) mgK. L - ¹ as potassium sulfate K%41.5 and four concentrations of chelated Iron EDTA(Fe%13)(0, 50, 100, 200)mg Fe.L - ¹. The results showed that the suitable) K (foliar nutrition treatment was 3000mgK.L - ¹ which caused significant differences in plant height, number of leaves, stem diameter, leaf area, dry matter of green plant, ear length, number of rows per ear, number of grain per ear, weight of 500grains, grain yield, chlorophyll, concentration of K and concentration of Fe as compared with control, it in order to195.87cm, 15.51 leaf, 27.32mm, 59.11dm2, 6017g.m2, 20.158cm, 17.025row, 516.75grain, 143.75g, 9.507t.ha - 1, 51.34 SPAD units, %3.003, 145.36mg.Kg - 1.Using Fe - foliar nutrition treatment was 50mgFe.L - ¹ caused significant differences in plant height and number of leaves it 193.76cm and 15.54 leaf، and 100mgFe.L - ¹ caused significant differences in stem diameter, leaf area, dry matter of green plant, ear length, number of rows per ear, number of grains per ear, weight of 500grains, grain yield, chlorophyll and concentration of K as compared with control it in order of 27.76mm, 60.41dm2 , 6004g.m2, 20.95cm, 17.15 row, 505.33 grain, 143.00g , 9.646 t.ha - 1, 50.08 SPAD unit, 2.9284%.While 200mgFe.l - ¹ caused low of all traits parameters except concentration of Fe in leaves was 188.18 mg.Kg - 1.The interaction between potassium and iron K3000 * Fe100 of significant effect in more traits parameters compared with control treatment and concentration of potassium decreased high level of iron(200mgFe.L - ¹) of monitor form
