Changes in the Status of Secondary and Micronutrients in Soil with Wheat and Bajra Cultivation

Results of field experiment with wheat-bajra cropping sequence showed that a single crop of wheat (var. Kalyansona) yielding 35.5 q/ha grain and 58.3 q/ha straw reduced the content of available Mg, Fe, Mn, Zn and Cu by 99.46,9.05, 12.68, 1.59 and 0.70 kg/ha, respectively and enriched exchangeable Ca by 828.8 kg/ha in 0–30 cm depth of the soil. On the other hand, bajra crop (var. HB 3) yielding 24.1 q/ha grain and 69.5 q/ha straw reduced the content of Ca and Cu by 882.6 and 0.47 kg/ha respectively, but enriched the content of Mg, Fe, Mn, and Zn by 18.81, 4.32, 6.12, and 0.87 kg/ha, respectively. However, the overall effect of these two crops in the rotation in a year resulted in the depletion of all these elements.
