Abstract
The present investigation entitled “Propagation studies in jamun [Syzygium cumini (L.) Skeels] under rainfed conditions of Jammu sub-tropics” was carried out in the year 2019-20, at the Research Farm, Division of Fruit Science, FoA, Chatha, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu. Two methods each of budding and grafting viz., T-budding, patch budding, tongue grafting and wedge grafting were tried to ascertain the best method of propagation in jamun. All the four methods of propagation were performed at different periods of time i.e. 4th week of July, 2nd week of August and 4th week of August under two different growing conditions i.e. open condition and shade net condition.
Among various methods and different timings under two different environmental conditions of propagation, significantly minimum days taken to bud sprouting (16.45 days) were observed in wedge grafting performed during 4th week of July under open condition. Whereas, higher length in scion wood (43.86 cm) was observed in wedge grafting when performed during August 2nd week under shade net condition. Wedge grafting also showed highest per cent sprouting (74.66 %) and success (69.33 %) during 2nd week of August under shade net conditions. Maximum stock-scion ratio was observed as 2.04 in patch budding during 2nd week of August under shade net conditions. Maximum number of shoots (8.77, 10.30), number of leaves (19.33, 24.32), shoot length (27.22 cm, 53.71 cm), average leaf area (21.34 cm2, 25.70 cm2), plant height (36.90 cm, 93.78 cm) were recorded after 90 and 180 days of propagation, in wedge grafting performed during 2nd week of August under shade net conditions. Maximum increase in stem girth (0.97 cm, 1.28 cm) was also recorded in wedge grafting performed during 2nd week of August after 90 and 180 days of propagation, respectively under shade net conditions.
It was concluded that among all the propagation methods and timings, wedge grafting performed during 2nd week of August provides highest per cent propagation sprouting, success and better growth parameters of jamun plant under shade net conditions. However, wedge grafting performed during 4th week of July under open conditions took minimum number of days for sprouting/establishment.
