The effect of different growing media (soil, soil+FYM, soil+vermicompost, soil+cocopeat, soil+sand+FYM, soil+sand+vermicompost and soil+sand+cocopeat), hormonal treatments (Control, IBA 500 ppm, NAA 500ppm and IBA+NAA 500ppm each) and growing seasons (rainy and spring) on the number of sprout per cutting, number of primary roots per cutting, number of secondary roots per cutting and survival percentage of cuttings of lemon cv. Pant Lemon-1, was evaluated. Among the different growing medium, number of sprouts per cutting (2.58) with soil+sand+vermicompost, number of primary roots per cutting (9.03) and number of secondary roots per cutting (16.67) with soil+sand+cocopeat and survival percentage (82.23) with soil+sand+FYM, recorded maximum. Growth hormones IBA 500 ppm Hormonal combination of IBA 500 ppm+NAA 500 ppm were resulted maximum number of primary roots (7.74) and secondary roots (16.19) per cutting. Over all compare between spring and rainy seasons, spring season was found superior regarding number of sprout per cutting (2.29) and number of primary roots per cutting (7.30). Whereas, number of secondary roots per cutting (15.30) and survival percentage (77.37), were more in spring season.
Growing medium of soil + sand and cocopeat, hormonal combination of IBA 500 ppm + NAA 500 ppm in spring season are best treatments for rooting ability of cuttings.
Growing medium of soil+sand+FYM and hormonal treatment (IBA 500 ppm) are effective as a survival of lemon cuttings in rainy season.
