Abstract:
Acid lime (Citrus aurantifolia Swingle), belongs to the family Rutaceae. Citrus is the third largest fruit crop grown in India, next to mango and banana. It is generally grown under both tropical and subtropical climatic conditions. The present investigation was carried out during 2019 at Citrus research station, Petluru, Dr. YSRHU, A.P. The present experiment consists eight treatments with three replications which was laid out in a Randomized Block Design. Among all the treatments with regard to growth, yield and quality parmetersT₄ i.e ZnSO4 foliar spray + Fe filings mixed in FYM + MgSo₄ foliar spray recorded maximum tree girth (42.70 cm),tree volume (32.10m³, fruit weight (58.26 gm),maximum number of fruits (2251.7/plant) and yield (118.49 kg/plant). The treatment T_{7 i.e} ZnSO₄ foliar spray + FeSo₄ foliar spray + MgSo₄ foliar spray recorded highest juice percentage (45.65%)and vitamin C (33.96 mg/100ml^-1) as compared to other treatments. While among all the treatmentsT₁ ZnSo₄ soil application + Fe EDTA soil application + MgSo₄ soil application recoded highest TSS(7.8%)and acidity (7.15%) compared to other treatments. However the lowest growth and yield recorded in T8 Control (Without any micronutrients) foliar spray.
