Abstract:

Zinc (Zn) malnutrition is apprehended as most common form of “Hidden Hunger” round the globe especially in areas having alkaline calcareous soils with low micronutrients availablilty due to high soil pH and rapid fixation. Current study was planned to identify the effective Zn source and mode of application for improving physiology, yield and Zn bioavailabilty under various phosphorus (P) amendments in wheat crop. Studies were conducted at the experimental field area of Nuclear Institute for Agriculture and Biology (NIAB) to investigate the effect of Zinc (Zn) fertilization using different methods of Zn application on growth and Zn uptake of wheat. Zinc was applied as foliar spray of 0.5% Zn solution(FZ), seed coating 1% Zn (SC), band placement of zincated urea (ZCU), Soil Zn @ 15kg ha-1 (SZ), Soil Zn @ 15 kgha-1+ 0.5% Zn foliar spray (SFZ). The zinc treatments were applied with soil application of DAP (Di ammonium phosphate) and PA (Phosphoric acid). Foliar Zn was applied through spray 2 times at different growth stages (booting and grain filling). Other fertilizers were applied at recommended rates. Experiment was planned in randomized complete block design (RCBD) with three replications. Two main blocks were prepared receiving DAP and PA fertilizers. Growth, yield and quality parameters were recorded wherein exogenous Zn application was found not only to improve plant growth and yield of wheat but also the Zn bioavailability by decreasing Phytate to Zn ratio (PZR) in grains of wheat grown in Zn deficient alkaline calcareous soil. Though only soil Zn treatments (Soil application, seed coating and Zn-coated urea) are not as efficient as foliar Zn application. It may be inferred that appropriate soil plus foliar Zn application approach is required for achieving proper plant growth and development and improving bioavailable Zn content in grain of wheat grown on alkaline calcareous soils.
