Dynamics of zinc fraction in a calcareous Vertic haplustept under AICRP-LTFE soils


Author(s): AM Viramagama, AV Rajani, MS Solanki and AA Maheta

Abstract: This investigation initiated which comprised of samples derived from long term fertilizer experiment started 20 years back on Vertic Haplustept calcareous medium black clayey soils of Junagadh. The samples were subjected to fractionation of micronutrient viz., Zn. The LTFE experiment involved 12 treatments including untreated control and 4 replication which was subjected to analysis of variance in order to find out the effect of various treatments on yield, correlation, regression, path and fractions of Zinc were also change in a long term cycle of 1, 10 and 20 years. The results revealed that DTPA available Zn was maintained high quite above critical values (0.5 to 1.0 ppm) and did not indicate any need to supplement Zn nutrient in near future. Particularly DTPA available Zn recorded significantly higher value under T4 (100% NPK+ ZnSO4 @ 50 kg ha-1) Followed by T8 and T9. FYM is essential for maintaining soil fertility at long run.
