| In order to study the vegetative characteristics, yield and seed quality of canola as influenced by silicon, sulfur and Tecamin flower, an experiment was conducted in in the farmer’s condition in the Darzian, 12 km far from Marivan during the two consecutive growing seasons 2017-18 and 2018-19 in the form of spilit- split plots in a randomized complete block design with three replications. In the main plot, silicon foliar application at two levels (0 and 2 kg/ha), in the sub-plot, sulfur foliar application at three levels (0, 1 and 2 liters per hectare) and also in the sub-sub plot, foliar application of reproductive growth biostimulant of Tecamin flower at three levels (0, 1 and 2 liters per hectare) were considered. The results of combined analysis showed that stem weight under the influence of the year showed a significant difference at the level of 5%. Silicon application affected significantly the number of axillary stems, pod weight, pod length, grain weight and seed protein and Tecamin foliar application also affected significantly all studied traits such as plant height, first pod height from the ground, number of axillary stems, stem weight, pod weight, pod length, grain weight, grain yield, oil and protein seed. Also the mentioned traits except plant height, number of axillary stems and pod length affected significantly by sulfur. Based on finding, silicon (2kg/ha) and sulfur and Tecamin (2L/ha) increased the studied characters. In this study sulfur and Tecamin increased the grain yield as: 7.42 and 14.12% compared to control, respectively. Protein seed significantly increased by silicon as 0.66%. Also oil and protein seed increased by 2 litre sulfur (3.33-3.34%) and 2 litre Tecamin (1.2-1.31%). Based on the interaction effects, silicon and sulfur foliar application as 2 L/ha were increased the oil seed by 4.03%. Also seed protein increased by 5.23% in second year by silicon and sulfur and Tecamin (2L/ha). Therfore, according to the effects of the used treatments on the seed yield and quality increasing and considering the costs of preparation and foliar application, the utilization of sulfur and Tecamin flower as 2L/ha is recommended in similar climatic condition and in canola cultivation. |
