摘要：Mung bean(Vigna radiata L.) is a significant pulse legume crop of Pakistan. It is considered as a meat for poor community. Malnutrition has become a crucial problem worldwide. Stunted growth is in-creasing gradually due to the micronutrient defi-ciency in food. Zinc (Zn)has a prominent role in evolution and development mechanism of living or-ganisms. Zn biofortification is easy to increase Zn content in food material by using modern agriculture and nanotechnology techniques. Zn deficiency and stunted growth in human beings can be reduced by Zn biofortification in mung bean pulse. Considering above mentioned scenarios, a field research was ex-ecuted to assess mung bean Zn biofortification using different available sources alone or in combination to biofortify mung bean seeds. Zn sources i.e.ZnO, ZnSO4.EDTA-Zn, Zn-lysine chelate, ZnO nanopar-ticles alone and ZnO nanoparticles along with lysine were applied through foliar application @0.1%Zn concentration, The experiment was laid out in sum-mer season of 2018 in RCBD(Randomized Com-plete Block Design) at Student's Research-Farm, University of Agriculture,Faisalabad. Mung bean variety"Azri-Mung-2006"was raised in field exper-iment as a trial crop. Results showed that foliar ap-plied Zn-lysine significantly increased the plant height(60.83 cm),root length(38.40 cm),numberof pods(41.66), pod length(12.96 cm), 1000-seed weight (51.26g) and seed yield (2065.60 kg ha-1). Foliar applied ZnO nanoparticles significantly in-creased the seed Zn contents(33.33 mg kg-1) and leaf Zn contents (28.34 mg kg-1)while maximum shoot zinc contents(56.33 mg kg-1)were observed where foliar ZnO nanoparticles with lysine was ap-plied and maximum root Zn contents (32.66 mg kg-1)were observed where foliar EDTA-Zn was applied. Thus, this is first field investigation which showed the efficacy of different Zn sources for fortification of mung bean and results of this study can be em-ployed on biofortification of other crops to copemal-nutrtion.
