Abstract
The present experiment entitled “Effect of conjoint application of organic and inorganic
nutrient sources on soil properties and productivity of Peach” was conducted at experimental farm of
the College of Horticulture and Forestry, Neri, during the year 2020. The experiment was laid out in
Randomized Block Design with thirteen treatments replicated thrice. The treatments consisted of T1 (100
% NPK + FYM 25 kg tree-1), T2 (75 % NPK+ FYM 25 kg tree-1), T3 (50 % NPK + FYM 25 kg tree-1), T4
(100 % NPK +VC 15 kg tree-1), T5 (75 % NPK + VC 15 kg tree-1), T6 (50 % NPK +VC 15 kg tree-1), T7
(Jeevamrit @ 6.6 % at 15 days interval), T8 (Jeevamrit @ 6.6 % at 15 days interval + FYM 25 kg tree-1),
T9 (Jeevamrit @ 6.6 % at 15 days interval +VC 15 kg tree-1), T10 (75 % NPK + FYM 25 kg tree-1+
Jeevamrit @ 6.6 % at one-month interval), T11 (50 % NPK + FYM 25 kg tree-1+ Jeevamrit @ 6.6 % at
one-month interval), T12 (75 % NPK +VC 15 kg tree-1+ Jeevamrit @ 6.6 % at one-month interval) and T13
(50 % NPK + VC 15 kg tree-1+ Jeevamrit @ 6.6 % at one-month interval). The highest increase in tree
height (26.70 %), annual shoot growth (58.47 cm), average fruit weight (95.04 g), fruit yield (10.67 kg
tree-1) was recorded under 75 % NPK +VC 15 kg tree-1+ Jeevamrit @ 6.6 % at one-month interval (T12).
The advancement in flower initiation was also recorded in this treatment. Fruit quality parameters viz. total
soluble solids (12.33 ⸰Brix), titrable acidity (1.18 %) and ascorbic acid (16.88 mg 100 g-1) were found
highest in 100 % NPK +VC 15 kg tree-1 (T4). Leaf N (3.65 %), S (0.404 %), Mn (64.53 ppm) and Fe
(227.49 ppm) contents were recorded significantly higher in 75 % NPK +VC 15 kg tree-1+ Jeevamrit @
6.6 % at one-month interval (T12) whereas, leaf P (0.310 %) and Zn (26.33 ppm) was observed
significantly higher in 100 % NPK +VC 15 kg tree-1 (T4). Soil organic carbon (2.85 and 2.08 %), available
N (428.59 and 397.23 kg ha-1), available P (70.63 kg ha-1), available K (443.52 and 436.05 kg ha-1),
available S (50.09 and 49.39 mg kg-1) and Cu (0.92 and 0.88 mg kg-1) contents were significantly higher in
75 % NPK +VC 15 kg tree-1+ Jeevamrit @ 6.6 % at one-month interval (T12), however, electrical
conductivity (0.191and 0.188 dS m-1), cation exchange capacity (12 and 11.47 C mol p+ kg-1 soil), Zn (6.09
and 5.65 mg kg-1), Mn (31.78 and 29.79 mg kg-1), Fe (102.89 and 95.11 mg kg-1) in surface and subsurface
layer were significantly higher in 100 % NPK +VC 15 kg tree-1 (T4). Further, maximum microbial count
(219.00×105 cfu g-1) was recorded higher in 75 % NPK +VC 15 kg tree-1 + Jeevamrit @ 6.6 % at onemonth
interval (T12). From these results it is concluded that treatment comprising 75 per cent NPK +VC @
15 kg tree-1 + Jeevamrit @ 6.6 % at one-month interval (T12) proved best in attaining maximum growth
and yield parameters as well as physical, chemical and biological properties of soil over university
recommendation of fertilizers and manures (100 % NPK + FYM 25 kg tree-1) (T1) for peach crop in
subtropical region of Himachal Pradesh.
