Abstract :

In order the effect of Application of bio fertilizer (nitroxin) on quantity and quality of borage under Water deficit stress an experiment in split plot randomized based on complete block design with three replications in 2014 at the Agricultural Research Station of ROUDEHEN Islamic Azad University done. treatments were first factor drought in four levels (control, stress at Vegetative stage, stress at flowering stage, stress at Vegetative + flowering stage) and the second factor consisted of four levels of fertilizer treatments (100% chemical fertilizer, 50% chemical fertilizer+ bio fertilizer (nitroxin), 25% chemical fertilizer+ bio fertilizer) respectively. Results showed a significant effect of cut irrigation on plant height, essence percentage, mucilage percentage, flower yield, Chlorophyll, but the effect of cut irrigation on essence yield was not significant. Effect of fertilizer treatments on plant height, essence yield, flower yield and Chlorophyll was significant and the percentage of mucilage was not significant. Interactions between cut irrigation and fertilizer treatments on essence yield (1.75 kg\ha), flower yield (481 kg\ha) was significant and 50% chemical fertilizer+ bio fertilizer was best treatment. The Least flower and essential oil yield in the 100% chemical fertilizer+ stress at Vegetative + flowering stage treatment with an average of 301 and 1.136 kg per hectare was obtained.
