چکیده
Experiment was conducted as split plot in a randomized complete block design with three replications in Kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant Borage (Borago officinalis L). Irrigation tritments include: a) ۳۰% less water than crop requires invegetative, b) inreproductive,c) in vegetative+reproductive and d) control (۱۰۰% crop water requirement). Fertilizer treatments include applying ۱۰۰% chemical fertilizer, ۵۰% chemical fertilizers+biological fertilizers and ۲۵% chemical+biological fertilizers. The results showed that grain yield was decreased under low irrigation. Low irrigation during vegetative and reproductive stages was found to ۹.۵ and ۱۵.۷%. Low economic efficiency of low irrigation water in vegetative stage was much more than reproductive and vegetative growth less up to ۳۲.۲% and ۲۷.۱% respectively. Integrated use of organic and chemical fertilizers by ۵۰% and ۲۵% alleviated cost of fertilizer to ۳۸% and ۶۳% respectively. Among deficit irrigation treatments, vegetative low irrigation treatment had net and gross income to low reproductive irrigation and low vegetative reproductive irrigation. The ۵۰% chemical+bio fertilizers in comparison with ۱۰۰% chemical fertilizers had higher net and gross income than vegetative, reproductive and vegetative+reproductive stages. The mentioned treatments compared with ۱۰۰% chemical fertilizers improved benefit-cost ratio to control treatment and vegetative deficit irrigation ۲۷% and ۱۵.۷% respectively. Based on results, vegetative deficit irrigation showed the better economic indexes in comparison with other treatments. However, in case deficit irrigation is necessary, the vegetative deficit irrigation and using ۵۰% chemical biofertilizer are recommended.کلیدواژه ها
