Abstract
The present investigation entitled "Propagation studies in Jamun [Syzygium cumini (L.) Skeels] under Punjab conditions” was carried at Punjab Agricultural University, Regional Fruit Research Station, Bahadurgarh, Patiala during 2020-21. Jamun cv. Konkan Bahadauli was used as scion and Desi jamun as rootstock. Plants were propagated by five different propagation techniques viz., wedge grafting, side grafting, T-budding, patch budding and inarching in the months of January, February, March, May, June, July and August. Various parameters recorded were percent graft survival, days to bud sprouting, duration of bud sprouting, leaf area (cm2) and growth parameters such as plant height (cm), scion girth (mm), stock girth (mm), number of shoots per graft, shoot length (cm) and number of leaves per graft were recorded at intervals of 60, 90 and 120 days after grafting. The plants propagated by wedge grafting technique in the month of February and July had graft survival of 76.67
and 70.00 percent, respectively. Early bud sprouting was observed in wedge grafting. The maximum average plant height 120 days after grafting was recorded in inarching (90.66 cm) followed by wedge grafting (53.24 cm). The maximum benefit cost ratio was recorded in wedge grafting followed by inarching. It is concluded that wedge grafting should be done before flowering and after fruit harvesting i.e during the month of February and July for successful propagation of jamun under Punjab conditions.
