The Scrutiny of Interaction between Iron Nano Chelate and Chlophony Hydrogel on Soil Chemical and Nutritional Properties

About one million hectares of lands in Khuzestan are salty and a great part of agricultural lands under cultivation of corn at the south of Khuzestan are located in this region. This investigation was conducted in a farm located in Ramhormoz in 2011 in order to investigate the interaction of iron nano and chlophony hydrogel as a superabsorbent on the yield of grain corn (Zea Mays L.) and some chemical and nutritional properties of soil in rather salty soils in completely randomize design with four treatments and four repetitions experimental treatments consisted of: first treatment: conventional farmers (control), second treatment: iron nano chelate fertilizer (10 kgha-1), third treatment: super-absorbent polymer(40 kgha-1), fourth treatment : second treatment + third treatment. Results showed that the most increase in yield was obtained as a result of iron nano chelate consumption by 5517.667 kg/ha and the least increase was seen in control treatment by 4256.33 kgha-1.The results of data variance analysis showed that iron nano chelate treatment and the treatment of simultaneous consumption nano and superabsorbent has a remarkable impact on weight features of a thousand grains, grains in ear and grains in ear raw. Raw in ear and bush height features were not considerable under the treatments. Chemical properties of soil including saltiness, acidity and saturation percentage were not remarkable in tow depths, except for saturation percentage which showed a significant difference, between superabsorbent treatment and control treatment in depth of 30-60 cm. All absorbable nutritional elements of soil were not considerable in the tow measured depths except phosphorus and manganese which showed remarkable difference in depth of 0-30 cm in level 5% of Duncan test. According to the results of this test and of nano and superabsorbent has a remarkable impact on weight features of a thousand grains, grains in maize and grains in maize raw. Raw in maize and bush height features were not considerable under the treatments. Chemical properties of soil including saltiness, acidity and saturation percentage were not remarkable in two depths , except for saturation percentage which showed a significant difference Between superabsorbent treatment and control treatments in depth of 30–60 cm. All absorbable nutritional elements of soil were not considerable in the two measured depths except phosphorus and manganese which showed remarkable difference in depth of 0–30 cm in level 5% of Duncan test. According to the results ti the results of this test and computation of expenses of materials used in the test it is suggested to use iron nano chelate fertilizer in order to gain better yield in grain maize.
