Abstract
A field experiment entitled “Response of Integrated Nutrient Management on Growth, Yield,
Quality and Shelf life of Plum (Prunus salicina Lindl.) cv. Kala Amritsari”, conducted during 2016-17 and
2017-18 at Experimental Orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar. It
comprised of 11 treatment levels of plum in randamised block design with three replications. The main objectives
were to study the effect of integrated nutrient management on growth, yield and quality of plum, to study the effect
of integrated nutrient management on shelf life. Growth parameters of plum were significantly affected by the
organic and inorganic fertilizer. The maximum increase in plant height (0.27 m), per cent increase in plant height
(4.91 %), annual shoot growth (70.63 cm), leaf area (13.13 cm2) and chlorophyll index (23.88) was observed in the
treatment T11: (75% of N + vermicompost + FYM + biofertilizers). The significantly higher fruit weight and yield
was reported by the application of T11: (75% of N + vermicompost + FYM + biofertilizers) with 12.35 gm and
53.43 kg/tree, respectively. The maximum number of flowers/ feet of shoot (87.19), number of fruit set per feet of
shoot (32.58), final fruit set (20.50%), per cent final fruit set (23.50%) in the treatment T11. The fruit physical and
chemical parameters were found by the application of the treatment T11 with maximum polar diameter (2.43 cm),
equator diameter (2.56 cm), fruit volume (17.03 cm3), stone weight (0.61 gm), pulp weight (11.74 gm), pulp to
stone ratio (19.12), fruit firmness (4.01 kg/cm2), acidity (1.77 %) and reducing sugar (1.71 %) content. Whereas,
maximum initial fruit set (38.30 %) reported in T9, but the maximum anthocyanin (17.01 %) and TSS (9.70 %)
were found in T7: (75% of N + vermicompost + biofertilizers) and T6: (50 % of N + vermicompost + biofertilizers)
respectively. The total sugar was recorded in T7 & T9 with (7.80 %) and reducing sugar was in both T4: (50 % of N
+ vermicompost) & T7: (75 % of N+ vermicompost + biofertilizers) with (6.12 %).
The post harvest shelf life were found significantly higher in the treatment T11: (75 % of N +
vermicompost + FYM + biofertilizers) with maximum fruit firmness, higher acidity and lower total sugar, TSS,
physiological loss in weight and decay loss, followed by T10: (50 % of N + vermicompost + FYM + biofertilizers)
and T9: (75 % of N + FYM + biofertilizers) while, the maximum anthocyanin was reported in T7: (75 % of N +
vermicompost + biofertilizers).
The leaf nutrient content was reported significantly maximum in the treatment T11 (viz., N (1.77 %), Mg
(0.68 %), Fe (252.62 ppm), Ca (2.50 %), Cu (12.26 ppm) and Zn (25.99 ppm)), while treatment T9: (75% of N +
FYM + biofertilizers) reported maximum leaf P (0.27%) and K (3.10 %) content over other treatments. The
availability of soil nutrients viz., N (140.14 kg/ha), K (290.51 kg/ha), Fe (8.26 ppm) and Cu (0.75 ppm) were
reported significantly higher in the treatment T11: (75% of N + vermicompost + FYM + biofertilizers). Whereas,
the treatment T10: (50% of N + vermicompost + FYM + biofertilizers) was reported significantly higher Zn (2.50
ppm) content and the treatment T7: (75% of N + vermicompost + biofertilizers) reported maximum soil P and Mn,
with 16.11 kg/ha and 5.91 ppm, respectively.
