Abstract
The field experiment was conducted during the kharif season of 2016-17, the experiment entitled, “Studies on macropropagation technique in banana” was conducted at All India Coordinated Research Project on Tropical Fruits (Citrus), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with the objectives to study the response of different propagation media for the macropropagation and to find out the suitable media for the macropropagation of banana.
The experiment was laid out in Complete Randomized Design with 6 treatments viz. Sawdust + VAM (30g), Sawdust + Trichoderma viride (30g), Sawdust + VAM (30g) + Trichoderma viride ( 30g), Sawdust + IBA (Dipping in 0.25% solution) + Azospirillum (30g), Sawdust + BAP (4ml) + Bacillus subtilis (30g) and Sawdust + VAM (30g) + BAP (4ml) + Bacillus subtilis (30g) which were replicated four times.
The results of the investigation indicated that, among the different propagation media of Sawdust + VAM (30g) + BAP (4ml) + Bacillus subtilis (30g) gave better performance in macropropagation of banana on growth parameters.
In respect of different propagation media, Sawdust + VAM (30g) + BAP (4ml) + Bacillus subtilis (30g) recorded short time for bud initiation and total number of primary, secondary and tertiary buds. Observations recorded after transplanting of seedlings in polythene bags, the maximum plant height, stem girth, pseudostem girth, pseudostem height, leaves per plant, leaf width, leaf area, length of the longest root, girth of root, secondary roots, whole plant dry matter yield, rate of proliferation, survival %, plant vigour recorded maximum in Sawdust + VAM (30g) + BAP (4ml) + Bacillus subtilis (30g).
Description
The field experiment was conducted at All India Coordinated Research Project on Tropical Fruits (Citrus), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Selected 1-1.5 kg sword suckers from farm. The apical meristem is removed to a depth of 2cm leaving a cavity of 2 cm dia in the rhizome and the rest of the corm is given 6-8 cross wise cuts. 30g of Bio-fertilizers should be mixed with sawdust substrate. The primary buds should be decapitated by removing the juvenile meristem and 4-6 horizontal cuts to be given for the young rhizome. The same procedure should be repeated for secondary buds to produce tertiary bud. The separated plantlets were Red soil:Sand:Farm yard manure (1:1:1) filled in polybags with drainage holes. Plantlets were watered sufficiently and maintained under shade for 45 days.
