The results showed that signficant increase was found in the fruit weight and plant yield by the effect of runners removel and foliar application of Boron .However, runners removel had no significant effect in the fruit content of anthocyanin , vitamin C, and β-carotene while Folat concentration was increased significantly.

The highest concentration of anthocyanins was ( 44.24 & 49.50) mg in BB60 and BFe150 , the highest vitamin C were (266.5 & 262.9) mg in BB60 .

β-carotene was in maximum value (38.01 & 41.48) μg in BCa300 and CB60 while the highest content of folic acid was (327.0 & 397.6) μg in BB60 and CCa300 plants.

The fruits in CB60 has been characterized by less nitrate content whidh was ( 17.52 & 17.17) mg, while the lowest concentration of oxalate were ( 2.16 &1.80) mg in fruits of BFe150 and CB30 in two seasons respectively.
