Abstract:
The present investigation was carried out for two consecutive years of 2016 and 2017 at experimental orchard of Department of Horticulture, CCS HAU, Hisar to assess the performance of sweet orange cv. Blood Red to soil application of zinc sulphate. The plants were treated with soil application of zinc sulphate (ZnSO₄) two times i.e. half dose in second fortnight of February and half dose in second fortnight of May. The experiment comprises of six treatments, viz., Zinc sulphate (ZnSO₄) @ 50 g/plant, 100 g/plant, 150 g/plant, 200 g/plant, 250 g/plant and Control (No Zn application). The experiment was laid out in RBD, replicated three times with six treatments. The results revealed that soil application of zinc sulphate significantly affected the plant height, spread and zinc content of leaves of sweet orange. The maximum plant height, spread and zinc content of leaves was found with ZnSO₄ 250 g/plant among all the treatments.
