To evaluate the effect of cutting type (or the place cuttings were taken from) on rooting of cuttings of ornamental magnolia (Magnolia soulangeana) current experiment was taken place in early July 2013 in a greenhouse at the Gorgan university of agricultural sciences and natural resources. In the current study mother plants were selected within the university campus (called Pardis area) and taken cuttings were divided into four categories including: terminal-current season, none terminal-current season, annual and heel cuttings. Cuttings were then treated with concentration of 4000 mg/l of IBA and then placed in the substrate medium immediately. An RCBD design with 4 replications was used for statistical evaluation of the achieved data. Significance of the data was considered at 1% level of examined characteristics. Results showed that highest rooting score (%90.01) was seen with heel cuttings, however there was no significant difference between the mentioned treatment and current season cuttings. Maximum root length also was seen with heel cuttings which again there was no significant difference with current season cuttings. The highest fresh weight and root dry weight was observed with heel cuttings. From the point of view of the percent of survived plantlets after transplanting to pot, there were no significant differences among four types of cuttings.

With sustainable agriculture, precision farming has also been considered a big help and more stringent environmental protection with efficient use of inputs that will result in higher quality products. Most environmental damage is a result of using chemical pesticides for controlling plant diseases. Precision agriculture, along with effective structures, can be useful for reducing pollution and lowering losses due to plant diseases all without the use of chemical pesticides, or at least a minimal use of them.
