Abstract This article studied the effect of spraying KH_2PO_4(2 and 5 g·L -1 )on plant growth,yield,quality and viability of seeds of carrots.The results showed that photosynthetic rate,transpirational rate,stem diameter,internode length,umbel diameter and biomass significantly increased by foliar application of KH_2PO_4 of 2 g·L -1 .Therefore,seed yields and 1 000-seed-weight increased remarkablely,and the germination vigor improved significantly.
