the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis)

in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 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+ biofertilizer (nitroxin), 25% chemical fertilizer+ biofertilizer) respectively. nitroxin and biophosphat biofertilizers were used. results showed a significant effect of cut irrigation and fertilizer treatments on plant height, number of branches, number of leaves, number of flower, flower fresh weight. interactions between cut irrigation and fertilizer treatments on number of branches (with average of 5.76), number of flower (with average of 60) and flower fresh weight (with average of 1193 g/m2) was significant and 50% chemical fertilizer+ biofertilizer was best treatment.
