This experiment was carried out to study the effect of time of planting (mid-October, first week of February), different concentration of IBA (500 ppm, 1000 ppm, 2000 ppm and 3000 ppm) and planted in different types of growing media and their combinations viz., (cocopeat, vermiculite, perlite, cocopeat + perlite, cocopeat + vermiculite, perlite + vermiculite, cocopeat + vermiculite + perlite and sand + soil + FYM). Different shoot growth parameters viz., time taken for bud sprouting, sprouting percentage, time taken for first leaf emergence, number of sprouts per cutting, number of shoots per cutting, length of sprouted shoots, total number of leaves per cutting, plant height, cutting diameter and survival percent are recorded. Similarly, root growth parameters viz., total length of root (cm), number of segments, number of forks, number of root tips, diameter of root (maximum), diameter of root (average), estimated volume of root (cm3) and rooting percent of cuttings are also being recorded during this period. Among different concentrations of rooting hormone, guava cuttings treated IBA @ 3000 ppm resulted in maximum survival (66.80 %) and rooting per cent (57.49 %) whereas, cuttings planted during first week of February recorded maximum survival (62.43 %) and rooting per cent (53.11 %). However, cuttings grown in mixture of Cocopeat + Vermiculite exhibited maximum survival (64.54 %) and rooting per cent (55.22 %).EnglishThesis
