Abstract:

Though one sixth of the global population resides in India, paradoxically, one third of about two billion people are suffering from vitamin and micronutrient deficiency in India due to heavy dependence on cereals grown in Zn- deficit soils. With the hypothesis that the residual Zn present in soil can also enhance the grain Zn content, a study was conducted with wheat variety ‘HD 2329’ to assess the grain concentrations of Zinc (Zn), Iron (Fe) and Phosphorus (P) grown on residual zinc in soils with divergent characteristics. Wheat crop was grown in the same pots on residual Zn fertility in which rice cultivars were grown with six Zn treatments in a completely randomised design (Factorial). The results of the study clearly indicated that wheat crop yield was not significantly influenced by the Zn applied to previous rice crop i.e. residual Zn fertility. However, the Zn concentration in wheat crop grown on residual fertility across the treatments ranged 29.6 to 33 mg kg−1. Residual Zn could maintain 11.5% more grain Zn concentration as compared to control. Among the Zn treatments, 5 mg Zn kg-1 (basal) plus FYM (5 mg Zn kg-1) could maintain highest Zn (33 mg kg-1) as compared to other treatments in wheat grain and straw. Among the soils, CRIDA soil could maintain higher grain Zn as compared to IARI and Karnal soil. There was an increase in DTPA-extractable Zn content in soils due to application of Zn in all the soils except in which Zn was supplied through foliar spray. Zinc application @ 5 mg Zn kg-1 (basal) plus FYM (5 mg Zn kg-1) significantly increased the DTPA- extractable Zn content over control in all the soils with mean value of 2.2 mg kg-1. More or less similar trend was observed in DTPA- extractable Zn in soil samples collected and analysed after the harvest of the wheat crop.
