Abstract

The present study was conducted during the year 2004–05 at Horticulture Experimental Block of G. B. Pant University of Agriculture and Technology, Hill Campus, Ranichauri (Tehri Garhwal), Uttarakhand. The six organic manure treatments viz., FYM, leaf manure, chir pine needle compost, vermi compost, poultry manure and rabbit manure along with (no treatment) control were tested for various attributes on tongue grafted plant of apple cv. Royal Delicious. The experiment was conducted in RBD with three replications. The investigation indicated the highest grafting success (94.78%) under FYM treatment, while the control treatment showed the minimum grafting success of 85.4% only. The FYM application contributed to minimum days required for scion bud sprouting i.e., 12.00 days, while the maximum days were taken with the control (19.67 days). The use of FYM also resulted into maximum shoot length (149.40 cm) in the month of November at the stage of final uprooting while the minimum shoot length (115.90 cm) at this stage was observed with control. The FYM treatment also resulted into maximum girth of sprout (1.09 cm), number of nodes (60.50), number of leaves per plant (56.12), leaf area per plant (1422.08 cm2), leaf dry matter content (45.59%), root length (39.50 cm) and root: shoot ratio i.e., 0.264 and 1.90 on the basis of length and weight, respectively, however, minimum estimate of these were observed under control treatment. Out of the various organic treatments the rabbit manure contains maximum nitrogen (220.50 ppm), phosphorous (80.49 ppm) and potash (320.45 ppm), against the minimum mean nitrogen (182.70 ppm), phosphorous (40.49 ppm) and potash (280.46 ppm) found under the control. On the basis of above finding, it can be concluded that all the organic materials showed significant improvement in various growth attributes of grafted plants of apple and increase the availability of various nutrients in the soil.
