Abstract:
The present investigation on effect of composite micronutrient on growth and yield parameters of sweet orange was carried out at AICRP on Fruits, Dr. YSRHU - Citrus Research Station, Tirupati during 2022-23. The field experiment was laid out in Randaomized Block Design (RBD) with 8 treatments and three replications. Observations were recorded on growth and yield characters of sweet orange Cv. Sathgudi. The findings revealed that, treatment T₅ (RDF + soil application of composite micronutrient @ 125 g/plant) significantly increased growth parameters like canopy spread (E-W: 4.38 m & N-S : 4.30 m) and canopy volume (28.29 m³). Yield parameters like fruit length (7.55 cm), fruit breadth (7.76 cm), fruit weight (170.9 g), number of fruits per plant (201.67), yield per plant (24.61 kg/plant) were significantly increased under treatment T₅ (RDF + soil application of composite micronutrient @ 125 g/plant).
