Effect of Different Growing Media on Hardwood Cutting of Grapes (Vitis vinifera L.) cv. Pusa Navrang

Abstract

Aims: The study the influence of different growing media on the rooting and subsequent growth of hardwood cuttings of the "Pusa Navrang" grapevine.
 Study Design: Randomized block design were used.
 Place and Duration of Study: Conducted at Research Farm, College of Horticulture, Mandsaur, during the period November 2020- March 21.
 Methodology: Filling of Poly Bags: Before the cutting planting the 5 X 7-inch poly bags will be filled with different growing media. Three hundred sixty (360) poly bags of each growing media should be filled i.e., 360 bags of Soil, 360 bags of Soil + Sand (1:1 ratio), 360 bags of soil + sand + cocopeat (1:1:1 ratio), 360 bags of Soil + Sand + FYM (1:1:1 ratio) and 360 bags of Soil + Sand + Vermicompost (1:1:1 ratio).
 Preparation of Cutting: After the filling of growing media in poly bags, the hardwood cuttings of uniform size having 4-5 functional buds will be taken from healthy plants of Grapes variety Pusa Navrang from one year matured shoots planted at the grapes orchard at the research farm, College of Horticulture, Mandsaur.
 Planting: The cutting about 0.75 to 1 cm thick diameter will be taken and planted in poly bags with 2-3 functional buds below the ground. Before planting, the hole should be done from the planting place with the help of a stick to prevent the buds from injuries.
 Results: The ideal outcome was discovered for shoot parameters like shoot length (6.75 cm, 48.15 cm), number of nodes per shoot (6.23, 14.75), internodal length (2.31 cm, 5.36 cm), number of buds per shoot (10.16, 23.72), stem diameter (14.15 mm, 24.20 mm) at 60 and 90 DAP, stem fresh weight (13.79 g), stem dry weight (5.68 g) at 90 DAP. Root Parameters like number of primary (20.11, 28.12) and secondary roots (14.74, 25.37), root length (17.98 cm, 19.69 cm), root thickness (1.81 mm and 1.95 mm), whole root volume (16.97 cm2 and 21.72 cm2) at 60 and 90 DAP, fresh weight of root (5.15 g), dry weight of root (2.14 g) at 90 DAP. Leaf Parameters like number of leaves per plant (9.73, 22.20) at 60 and 90 DAP, fresh weight of leaf (1.51 g), dry weight of leaf (0.63 g), leaf area (49.21 cm2), leaf area index (3.61), specific leaf weight (23.08 mgDw.cm-2) at 90 DAP, while minimum days taken to emergence of 1st leaf (22.92 DAP) found in soil + sand + vermicompost (M5).
 Conclusion: Among five growing media the application of soil + sand + vermicompost 1:1:1 responded well in terms of rooting and shooting in hardwood cutting of grapes. The experiment needs to be accurately reproduced over a wider range of years, locations, and seasons in order to establish the reliability of the findings.
