Abstract

Present study was carried out at research Farm of College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh during 2019–20 to find out effect of PGRs and micronutrients on granulation disorder of citrus cv. Rangpur lime. Results observed significant effect of PGRs and micronutrient on minimizing granulation and increasing the yield of fruits. Among all the treatments NAA @300 ppm + GA3 @15 ppm + ZnSO4 @0.5% + CuSO4 @0.5% (T6) showed maximum improvement in yield and reducing the granulation disorder in which maximum increase in number of fruits/tree (799.25 fruits/tree), fruit weight (161.48 g), yield (129.06 kg/ tree) and minimum granulation (17.80%) was recorded as compared to control (35%). Maximum viable seeds/fruit (12) were also attributes from the treatment T6 which was at par with NAA @250 ppm + GA3 @10 ppm + ZnSO4 @0.5% + CuSO4 @0.5% (T5) as compared to control (4
