Abstract:
The present experiment entitled “Effect of months and varieties on success percentage of air layering and root characteristics of air layers of guava (Psidium guajava L.) under Raipur region of Chhattisgarh Plain” was conducted at research farm of Precision Farming Development Centre (PFDC), Department of Fruit Science, College of Agriculture, I.G.K.V., Raipur (C.G.) during the year of 2021-22. The success percent of air layering was recorded 86.34 percent in treatment T₁₁ (LM₂V₄) when, air layering was done during the month of August with Lucknow-49 variety of guava while, the minimum success percent of air layering was observed 64.29 percent in treatment T₁₅ (LM₃V₅) during September month. The maximum number of primary roots (13.36), number of secondary roots (43.56), fresh weight of primary roots (3.75g) and dry weight of roots (1.32g) were recorded under the treatment T₅ (LM₂V₂) respectively when, air layering was done during the month of August with Lalit variety of guava. The maximum length of primary roots (8.55 cm) and length of secondary roots (4.93 cm) were recorded under the treatment T₄ (LM₁V₂) respectively when, air layering was done during the month of July with Lalit variety of guava. The maximum diameter of primary roots (1.99 mm) and diameter of secondary roots (0.94 mm) were recorded under the treatment T₂ (LM₂V₁) respectively when, air layering was done during the month of August with Shweta variety of guava.
