Studies on pear propagation through cutting treated With indole butyric acid under Ranchi condition

Experiment was conducted to study the rooting behavior of types of pear cutting in different Indole Butyric Acid (IBA) concentrations on the role and growth behavior of sprouting, roots number, root and shoot length, leaves number and survival percentage of cutting during the year 2004–05 in Birsa Agricultural University, Ranchi, Jharkhand. The types of cutting and different concentration of IBA exhibited significant effect on the average number of sprouted cutting. The number of sprouted cutting first increased and then decreased with the time in all three types of cutting. Moreover, the number of roots per cutting was found to increase gradually throughout the course of investigation after planting in bed. The highest number of sprout were recorded in interaction in semi-apical cutting treated with 100ppm. The number of roots per cutting during 30 days interval were also highest in semi-apical cutting treated with 100 ppm IBA. Maximum number of primary and secondary roots were obtained in same condition after 150 days of planting. Among cutting, the semi-apical cutting gave maximum number of primary and secondary roots. The longest root, shoot, number of leaves, survival percentage of cutting in nursery and field were recorded maximum in semi-apical cutting treated with 100ppm concentration IBA.
