Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University.

    EFFECT OF NPK ON GROWTH AND NUTRITIONAL STATUS OF GRAFTED APPLE (Malus × domestica Borkh.) NURSERY PLANTS
    (UHF,NAUNI, 2019-09) CHAUHAN, PRIYANKA; SHARMA, NAVEEN C
    ABSTRACT The present studies entitled “Effect of NPK on growth and nutritional status of grafted apple (Malus × domestica Borkh.) nursery plants” was conducted during the year 2017-18 in the experimental nursery block of the Department of Fruit Science, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out in randomized block design, comprising 14 treatments of NPK doses viz., T1: NPK @ 12, 3 and 4.5 g, respectively/m2; T2: NPK @ 12, 3 and 9 g, respectively/m2; T3: NPK @ 12, 6 and 4.5 g, respectively/m2; T4: NPK @ 12, 6 and 9 g, respectively/m2; T5: NPK @ 15, 3 and 4.5 g, respectively/m2; T6: NPK @ 15, 3 and 9 g, respectively/m2; T7: NPK @ 15, 6 and 4.5 g, respectively/m2; T8: NPK @ 15, 6 and 9 g, respectively/m2; T9: NPK @ 18, 3 and 4.5 g, respectively/m2; T10: NPK @ 18, 3 and 9 g, respectively/m2; T11: NPK @ 18, 6 and 4.5 g, respectively/m2; T12: NPK @ 18, 6 and 9 g, respectively/m2; T13: Jeevamrut drenching (10%) at fortnight intervals and T14: Control (no chemical fertilizer). Each treatment was replicated thrice and well rotten FYM was added @ 8 kg/m2 nursery bed area to all the treatments. In Royal Delicious and Oregon Spur varieties of apple, respective maximum linear growth (187.42 & 156.62 cm), number of leaves per plant (56.00 & 53.00), leaf area (24.77 & 24.35 cm2), number of main roots per plant (4.83 & 6.00), root diameter (10.00 & 9.83 mm), length of main roots (1.34 & 1.41 m), total root length (18.35 & 14.90 m), fresh weight of roots (72.08 & 67.83 g), dry weight of roots (38.67 & 38.17 g), leaf P (0.30 & 0.28%) and leaf Ca (1.53 & 1.48%) were recorded in the plants fertilized with NPK @ 18, 6 and 4.5 g, respectively/m2 nursery bed (T11). However, in Royal Delicious and Oregon Spur varieties of apple, respective maximum increase in radial growth of stock (5.18 & 4.35 mm), increase in radial growth of scion (6.66 & 5.23 mm), internodal length (3.84 & 3.38 cm), fresh weight of shoots (140.52 & 95.51 g), dry weight of shoots (71.42 & 51.00 g), leaf N (2.47 & 2.33%) and leaf K (1.88 & 1.87%) were found highest in the plants treated with NPK @ 18, 6 and 9 g, respectively/m2 nursery bed (T12). The maximum available soil N (467.80 kg/ha), soil K (370.67 kg/ha) were exhibited by nursery beds fertilized with NPK @ 18, 6 and 9 g, respectively/m2 nursery bed (T12), whereas, maximum available soil P (78.87 kg/ha) and soil Mg (591.13 mg/kg) contents were recorded in the nursery beds treated with NPK @ 18, 6 and 4.5 g, respectively/m2 nursery bed (T11). The treatments T11 (N3P2K1) and T12 (N3P2K2) were statistically at par with respect to majority of plant growth parameters and nutritional status. Thus, application of 18.0 g N, 6.0 g P and 4.5 g K/m2 nursery bed respectively (T11) was found to be the most effective treatment for production of quality nursery plants of apple with well developed shoot and root systems.
