UPTAKE OF ZINC BY DIFFERENT VARIETIES OF WHEAT AS INFLUENCED BY ZINC CARRIERS IN CALCAREIOUS SOIL

Abstract

Efficacy of different zinc sarriers on growth and yield of different germplasm of wheat and their zinc uptake were studied by conducting pot experiments in calcareous solls of North Bihar. The wheat varieties according to their yield potential followed the trend as Kalyan Sone>H.D 1982> MP 1102>HO 1653> Sonalika. Response of different Zn carriers followed the following trend in production of wheat grain and straw as ZnSO, ZnCl,- Zno> Zn.(PO)> ZnCO,. The differential uptake of Za by different varieties of wheat could be arranged as ZnSO,>ZnCl,>Zno> Zne (PD)> ZnCO,. All the Zn carriers at higher levels of Zn application gave significantly greater uptake of Zn.
