International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
The L*, b* and h* values of pomegranate colour were found to decrease while, a* and c* values
increased with different nutrient management practices. The L*, b* and h* values decreased i.e.
77.35, 2.33 and 24.42 significantly with the application of INM (FYM + Solubilizers + RDF)
+Umber (Ficus racemosa) Rhizosphere Hybridized Soil over control and followed by INM
(FYM + Solubilizers +RDF) +Antibiotics with values 80.01, 2.64 and 26.21, respectively.
However, a* and c* values were increased to 13.91 and 10.40 with treatment T7 followed by
treatments T6 with values 12.43and 9.96, respectively.
Leaf nitrogen (2.47 and 2.53 %), phosphorus (0.26 and 0.28 %) and potassium concentration
(1.33 and 1.34 %) were increased with INM (FYM + Solubilizers+ RDF) + Umber (Ficus
racemosa) Rhizosphere Hybridised Soil which was statistically at par with INM (FYM +
Solubilizers + RDF) + Antibiotics and Antibiotics (Streptocycline) + RDF) at flowering and after
harvest, respectively. While, it was decreased with absolute control.
Conclusion
Yield of pomegranate and quality parameters (TSS, titrable acidity and colour of juice) were
improved with application of INM (FYM @ 15 kg per tree, Azotobacter @ 8 ml per tree, PSB @
8 ml per tree and Trichoderma @ 100 g per tree, 625:250:250 g N, P2O5 and K2O per tree) along
with Umber (Ficus racemosa) Rhizosphere Hybridised Soil (URHS) @ 25 kg per tree.
Pomegranate leaf nutrient concentration like total N, P and K were also increased with same
treatment.
