Effects of planting date and amount of Nitrogen and phosphorus fertilizer on characteristics of Balango (Lallemantia royleana) In Varamin semi-arid Climate of Iran.

In order to investigate the effect of planting date and nitrogen and phosphorus fertilizer amounts on morphological traits of the plant Balango (Lallemantia royleana) in ۲۰۲۲-۲۰۲۳ a study was conducted in Mr. Hadavand's farm in Sharifabad, Varamin on the outskirts of Tehran-Iran. Investigated factors: ۱- Planting date: Autumn, November ۱ and Spring, March ۱, and ۲- Nitrogen and Phosphorus fertilizers in three levels: control (without fertilizer), ۵۰% fertilizer (۳۰ kg/ha of pure N and ۵۰ kg/ha of P۲O۵) and ۱۰۰% fertilizer (۶۰ kg/ha pure N and ۱۰۰ kg/ha P۲O۵) it was recommended. The results of data variance analysis showed planting date fertilizer amount and interaction effects of planting date and fertilizer amount on all treatments were significant at ۱% probability level. The highest Flavonoid (۶.۲۸ ppm), mucilage percentage (۷.۴%) under the effect of treatment without fertilizer, spring planting date and ۱۰۰۰ seed weight (۱.۹۵ g) and seed yield (۸۸۵.۳۶ Kg/ha) were affected by ۱۰۰% autumn planting date fertilizer with (۶۰ kg/ha of pure N and ۱۰۰ kg/ha of P۲O۵).
