Abstract: An investigation was carried out to standardize the suitable grafting time for Kinnow over rough lemon rootstocks during the years 2019, 2020 and 2021. The treatments consisting of four grafting date viz. 8th January, 22nd January, 6th February and 21st February. Scion collected from mother plants of Kinnow mandarin were grafted by wedge grafting method in open field nursery. The results showed that grafting dates significantly affected the days taken for sprouting, number of buds sprouted/ graft, sprouting, survival and final graft success. The highest graft success 71-76% was observed when wedge grafting was performed on 6th February followed by 49-62% on 21st February with considerable growth of saplings. However, leaf relative water contents and chlorophyll contents were found non-significant for time of wedge grafting. Therefore, the study revealed that 1st fortnight of February is the most suitable time of wedge grafting in Kinnow over rough lemon rootstocks under north western agro climatic zone of Haryana (India)
