Studies on effect of soil and foliar application of micronutrients on quality parameters of sweet orange Var. Nucellar (Citrus sinensis Osbeck)

Abstract

An experiment was conducted to study the effect of soil and foliar application of micronutrients on quality parameters of sweet orange (Citrus sinensis 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 15 treatments and three replication. Observations were recorded on quality characters of sweet orange. The results were revealed that, the quality parameters like juice %, reducing sugar, non-reducing sugar, acidity, T.S.S, ascorbic acid, pH, total sugar, are most effective in (T13) Soil application of ZnSO4 @ 150 gm + MnSO4 @ 150 gm + Foliar spray of ZnSO4 @ 0.5 % + MnSO4 @ 0.5 % followed by (T14) Soil application of ZnSO4 @ 100 gm + MnSO4 @ 100 gm + Foliar spray of ZnSO4 @ 1% + MnSO4 @ 1%.
