Study of morphological traits, grain yield and yield components of Lallemantia iberica masses in response to tillage treatment in Khorramabad region

Increasing consumption and high economic value of urban medicinal plant Balangu Research on cultivation of this plant is essential. Due to better use of rainfall, water requirement and less fertilizer can be used as a new species of medicinal plants in rain fed conditions.

Methods & Materials: 

The experiment was conducted in the form of strip split plots based on a randomized complete block design in three replications in Khorramabad region in the 2016/17. Experimental treatments including two tillage methods (conventional tillage and non-tillage) and five Balangu masses including (Takab, Kalibar, Kurdistan (Sanandaj), Nazarkahrizi and Jolfa) were placed in sub-plots.

Plant height and number of seeds per hazelnut were affected by tillage methods. Biological yield in tillage method and Takab mass showed an increase compared to conventional tillage and other studied masses. Kalibar mass had the highest plant height, number of sub-branches and number of hazelnuts per plant. In soilless cultivation method, the highest plant height and number of hazelnuts per plant were obtained. The highest grain yields were related to the common tillage method in Kalibar massif, which showed a significant difference with the no-tillage method in this massif. Also, the lowest grain yield was obtained in the conventional tillage method and Julfa mass.

Non-tillage treatment can be replaced with conventional tillage system to reduce production costs, labor and energy consumption and optimal use of time and also reduce the movement of agricultural machinery on the farm.
