Influence of zinc, iron and manganese on growth and yield parameters of V1 mulberry (Morus alba L.)

Abstract

A field experiment was conducted to study the effect of soil application of zinc, iron and manganese on mulberry at Department of Sericulture, University of Agricultural Sciences, GKVK, Bengaluru-65 during 2018-19. Among the different treatments, T5 (350:140:140 NPK kg/ha/year + FYM 20 t/ha/year + micronutrient formulation of Zn, Fe and Mn @ 6 kg/acre) recorded significantly higher plant height (169.50 and 211.61 cm), shoot height (65.15 and 170.56 cm), number of shoots/plant (30.11 and 30.17), shorter internodal distance (5.13 and 5.14 cm), number of leaves/plant (548.67 and 567.56), leaf area (283.52 and 310.45 cm2), leaf yield (947.20 and 1040.81 g/plant) and leaf dry matter (359.05 and 552.05 g/plant) on 45th and 75th DAP in V1 mulberry. Compared to other treatments all the above-mentioned parameters found least in the control.
