The effect of humic acid, seaweed extract (Ascophyllum nodosum) and some micronutrients on growth and yield of maize (540 NS)

The use of chemical fertilizers has caused irreparable damage to the environment. For this reason, the process of moving agriculture towards sustainable agriculture, which is a kind of agriculture for human interests, is more efficient in using resources and is in balance with the environment. Thus, for the development of sustainable agriculture, the implementation of the system with sufficient input in combination with the use of chemical and organic fertilizers, especially biofertilizers as an alternative solution for agriculture to produce crop and maintain yields at an acceptable level are effective. In this regard, in order to study the effect of humic acid, seaweed extract and micronutrients on the yield and yield components of maize cultivar 540, as well as the effect of these factors on the activity of antioxidant enzymes in the experimental design of Spit Factorial based on a randomized complete block design with 4 replications In 1390, it was conducted in a research farm in Aradan city of Semnan province. The results show that the application of different treatments of humic acid, seaweed extract and micronutrients can affect the yield and different components of maize cultivar 540 and in some cases make significant differences, but in the diameter of the ear is significantly different. Failed. The results indicate that the use of different treatments of humic acid and micronutrients is effective on the activities of antioxidant enzymes, but in the case of seaweed extract, there is no evidence to confirm the effect of this factor on the activity of enzymes studied. Also, applying different treatments of the three mentioned factors is effective on the growth parameters of the studied plant. Author: Mehrnoosh Rafiei (Islamic Azad University of Damghan)
