Abstract:
A field experiment was carried out on comparative basis in Apple orchards of village Kanelwan of District Anantnag, during the year 2017 and 2018. The two orchards selected were managed on two contrasting aspects of cultivation. The conventional orchard was cultivated on the basis of recommendation from Sher-e-Kashmir University of Agricultural Sciences and Technology-Kashmir, however, the organic orchard was managed totally on organic basis of cultivation. The conventional orchard of apple was treated with Nitrogen (100 ppm, 200 ppm and 300 pmm), Phosphorous (30 ppm, 40, ppm and 50 ppm) and Potassium (100 ppm, 150 ppm and 200 ppm) nano- fertilizers, while the organic apple orchard was treated with Humic acid (0.05%, 0.10% and 0.15%) and Fulvic acid (1.5%, 2.5% and 3.5%). The experiment was conducted in Randomized Completely Blocked Design replicated thrice. The foliar application of N, P and K nano fertilizers and Humic and Fulvic acid was done at two stages to meet the fertilizer requirements, one just before the pink bud stage and the other just before the pea size stage of apple. The maximum yield was recorded under conventional orchard was recorded in N application @ 300 ppm in both the years (28.15 and 29.89 tons/ha respectively), furthermore, under organic apple cultivation application of Humic acid @ 0.15% recorded highest yield (19.96 and 20.97 tons/ha respectively). The economic assessment of the experiment revealed that application of P nano fertilizer @ 50 ppm resulted in highest net B:C ratio of 6.31 and application of humic acid @ 0.15% recorded highest B:C ratio of 5.51. The experimental results of the present study predicted that application of nano-fertilizers in conventional system and humic and fulvic acid in organic system will result in increased yield and returns.
