​Effect of Foliar Applied Nitrogen with Growth Regulators (2,4 D, GA3, Amrut-pani) and Soil Applied Potassium on the Management of the Rough-skin Disorder of Nagpur Mandarin (Citrus reticulata Blanco)

Background: Rough-skin disorder mainly occurs in 6-12 years old young and senile orchards of Nagpur mandarin due to excess application or availability potassium. The characteristics rough-skinned fruits are large fruit size with rough textured peel, segments loose intact rind, improper shape (fruit length breadth ratio is equal one more than one), reduced juice per cent TSS. Methods: Based on the incidence rough-skin disorder, an orchard was earmarked at Hetikundi village Wardha district, Maharashtra for Mrig bahar during 2020. selected 10 old, spaced 6 m x grafted Rangpur lime rootstock. At harvest, yield attributes, physical critical quality viz. TSS, acidity, TSS/ acidity vitamin C content disordered normal were recorded according treatments. Result: Foliar plant growth regulators like 2,4-D 15 ppm GA3 reducing soil potassium high available soils skin improved rind texture physicochemical harvesting mrig bahar.
