EFFECT OF DIFFERENT PHYTOHORMONES ON ROOT AND SHOOT DEVELOPMENT OF MORINGA CUTTINGS

Abstract

The experiment was conducted at the Agroforestry Farm of Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from April 2019 to September 2019 to study the effect of different phytohormones on root and shoot development of Moringa cuttings. Cuttings were grown with five treatments viz., (i) T 1 (Honey), (ii) T 2 (Rooton hormone), (iii) T 3 ii

(Auxin), (iv) T 4 (Cutting hormone) and (v) T 5 (Water as control) by following the single factor Completely Randomized Design (CRD). Each treatment was replicated eight times. Data on the selected parameters were collected from randomly selected Cuttings of each treatment and analyzed statistically. In this experiment the highest results in respective parameter were found from T 1 (Honey) treatment. The highest number of buds at 15, 30, 45 and 60 days after transplanting (DAT) (3, 4.33, 4.33 and 6.67), number of branches per plant (6.67), number of leaves per plant (53.67), leaves length per plant (71 cm), leaves base length per leaf (15.33 cm), third internode length of leaves from top (9.6 cm) were found in T 1 treatment. The lowest number of buds found at 15, 30, 45 and 60 DAT (0.67, 1.33, 1.33 and 1.67), number of branches per plant (1.67), number of leaves per plant (13.67), leaves length per plant (44.67 cm), leaves base length per leaf (13.33 cm) and third internode length of leaves from top (7.57 cm) found in T 4 treatment. Maximum number of rachilas per leaves (17.33), number of roots per plant (20.33), root length per plant (18 cm), fresh weight of roots per plant (26.24 g), fresh weight of shoot per plant (730.51 g), dry weight of roots (5.98 g) and dry weight of shoot (158.07 g) found in T 1 Treatment. Minimum number of rachilas (14), number of roots per plant (9.33), root length per plant (9.33 cm), fresh weight of roots per plant (9.01 g), fresh weight of shoot per plant (149.11 g), dry weight of roots (2.10 g) and lowest weight of shoot per plant (33.76 g) found in T 4 treatment. The highest number of leaflets per leaves found with cutting hormone (398.67) and the lowest number of leaflets number found with Honey (331.67). Thus, it revealed that treatment T 1 (Honey) could successfully be used as rooting phytohormone in Moringa cutting propagation.
