Title : Effect of foliar application of zinc and boron on leaf nutrient status of lemon (Citrus limon Burm.) cv. Pant Lemon-1

Abstract :

The present study was carried out at Horticulture Research Centre, Patharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar to study the Effect of foliar application of zinc and boron on leaf nutrient status of lemon (Citrus limon Burm.) cv. Pant Lemon-1. The experiment was conducted in a Randomized Block Design with sixteen treatments and three replications during 2019-20. The soil of experimental site was sandy loam having pH 7.51 and EC 0.67 (dS m-1). Treatments, having different concentrations of zinc and boron (0.2%, 0.4% and 0.6% each) alone and in combination, were applied by the foliar spray method before flowering twicely in the month of April and May. Foliar application of Zn significantly increased the Zn concentration in leaves but it showed antagonism with the P and Mn concentrations. The treatment T10 (0.4% ZnSO4 + 0.2% H3BO3) showed the maximum increase in Zn concentration (33.30 ppm) while in the treatment T3 (0.6% ZnSO4) the concentration of P was decreased maximally by 0.02% and also a maximum decrease of 18.94 ppm in Mn concentration then their initial values. The maximum increase in boron concentration (16.91 ppm) was observed in the treatment T10 (0.4% zinc sulphate + 0.2% boric acid), but no regular pattern was observed with other nutrients like N, K, Fe, Ca and Mg. Therefore, it is suggested that for obtaining maximum yield and good quality fruits of lemon, foliar application of 0.4% zinc sulphate and 0.2% boric acid twice at one month interval in mid April and mid May before flowering was feasible.
