Effect of various concentrations of iba, type of cuttings and planting time on the rooting of cuttings of lemon (citrus limon burm.) cv. pant lemon-1 under valley conditions of garhwal himalaya

The present investigation was carried out at Horticultural Research Centre, Department of Horticulture, Chauras Campus, H.N.B. Garhwal University, Srinagar (Garhwal), Uttarakhand, India during the year 2012-13. The experiment consisted of thirty six treatment combinations, which comprised of concentrations of IBA viz; 200 ppm, 400 ppm, 600 ppm and control, type of cuttings viz; Softwood, Semi-hard wood, Hardwood cuttings and three planting times viz; November 20, December 20 and January 20. The experiment was replicated thrice with 10 cuttings in each treatment and a total of 360 cuttings were tested. The cuttings were planted in polythene bags (1 kg capacity). The results indicated that among the various treatment combinations, T2C3S2 (December planting time, 600 ppm concentrations of IBA and semi-hardwood cutting) treatment combination was recorded superior. Thus, it can be suggested that semi-hardwood cuttings of Lemon (Citrus limon Burm.), cv. Pant Lemon-1 planted in December after treatment with 600 ppm concentrations of IBA is an effective way to improve propagation under valley conditions of Garhwal Himalaya.
