Studies on effect of foliar application of urea, zinc sulphate and 2,4-D on quality parameters of sweet orange Var. Nucellar (Citrus sinensis L. Osbeck)

Abstract

An experiment was conducted to studies on effect of foliar application of urea, zinc sulphate and 2,4-D on quality parameters of sweet orange (Citrus sinensis L. Osbeck) Var. Nucellar.” was carried out at Sweet Orange Research Station, Badnapur, Dist. Jalna during 2018-19.The experiment was laid out in Randomized Block Design (RBD) with 8 treatments and three replication. Observations were recorded on quality characters of sweet orange. The results were revealed that, the quality parameters like reducing sugar, non-reducing sugar, acidity, T.S.S, ascorbic acid, pH, total sugar, are most effective in (T7) Urea – 1% + ZnSO4 -0.4% + 2,4-D – 20ppm followed by treatment (T6) ZnSO4 -0.4% + 2,4-D – 20 ppm.
