Abstract:
An experiment was carried out at instructional cum research farm, Department of Horticulture, BNCA, AAU, Biswanath Chariali during 2018-2019 to standardize the propagation method of custard apple (Annona reticulata) by stem cuttings. For carrying out the propagation by cuttings, three types of cuttings viz., Softwood cuttings (T₁), Semi hardwood cuttings (T₂) and Hardwood cuttings (T₃) were prepared and planted in poly bags at monthly interval from February to August, 2018 i.e. S₁ (February), S₂ (March), S₃ (April), S₄ (May), S₅ (June), S₆ (July) and S₇ (August). The experiment was laid out in factorial CRD with three replications. Among the treatments, T₂ (Semi hardwood) recorded the highest percentage of survivability (44.57%) at 60 days after planting of cuttings, number of primary roots (3.72) of cuttings, longest primary roots at 90 days after planting of cuttings (8.46 cm) and number of primary shoot (5.15) per cuttings at 90 days after planting of cuttings. Cuttings planted in July (S₆) recorded the highest numbers of primary roots (3.74) per cuttings. The percentage of survivability was highest (29.97%) in April (S₃) recorded at 60 days after planting of cuttings. Among all the treatment combinations, T₂S₇ (semi hardwood cuttings done in the month of August) recorded maximum length (9.20 cm) of primary roots at 90 days after planting of cuttings and number of primary shoots (6.67) per cuttings at 90 day after planting of cuttings.
