“…In post-harvest soil, Zn applied in conjunction with organics (Farmyard manure or Vermicompost) greatly enhanced biomass yield and Zn uptake by Indian spinach and DTPA-extractable Zn. The combined application of zinc and organics (Farmyard manure or Vermicompost) had a good effect on the distribution of various zinc fractions [8]. It is crucial to accurately measure the various forms of zinc and their relationships to soil characteristics and crop Zn uptake in order to enhance farming profitability over the long run.…”

A long-term experiment entitled “Study of correlation between soil chemical properties, zinc fractions and yield of rice under long term fertilization in Chromustert soil” was conducted at IGKV Raipur experimental farm during kharif 2019-20. This study comprised of ten treatments: control (no fertilizer), 50% NPK (sub-optimal dose), 100% NPK (optimal dose), 150% NPK (super optimal dose) and 100% NPK along with ZnSO4 @ 10kg ha-1, 100% NP, 100% N alone, 100% NPK along with farmyard manure @ 5t ha-1, 50% NPK along with blue green algae @ 10 kg ha-1 and 50% NPK along with green manure @ 40kg h-1. The experiment was laid out at a randomized complete block design which was replicated four times. The variations in Zn uptake by grain, straw and total (both grain and straw) varied from 17.29-129.73 g ha-1, 27.19 to 196.54 g ha-1 and 44.48 to 326.27 g ha-1, respectively. Amongst various treatments 100% NPK+ ZnSO4 had significantly higher values of Zn uptakes by grain, straw and total as compared to the control plot. The grain and straw yield of rice varied from 2430 to 6970 kg ha-1 and 3110-8364 kg ha-1, respectively with the application of various treatments of inorganic fertilizers and manures. From the statistical analysis it was observed that a correlation coefficient was computed between Zn fractions with respect to soil chemical properties and yield of rice that could possibly differ in imbalance and balance applications of varying doses of fertilizer. In this context, the significant correlation coefficient values (r) were obtained with all the parameters that showed organic carbon content in soil predominantly affected almost all individual fractions that ultimately maintain the pool of total Zn in soil for uptake by crop plants.
