Abstract

Among the oilseed crops soybean is most important crop that having edible oil and also protein in seeds. Zinc is most deficient micronutrient in soils of India. So, it is most important to manage through applying Zn containing fertilizers. A field experiment was conducted at research farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur during kharif season of 2019 to evaluate zinc uptake by soybean, use efficiency and status of available Zn in post harvest soil under different strategies of zinc application. Experiment was laid under randomized block design having fourteen treatments of zinc application strategies [T1-Absolute control, T2-RDF + No Zn, T3-RDF + 5.0 kg Zn ha-1, T4-RDF + spray of 0.5 % ZnSO4 at 35 DAS, T5-RDF + spray of 0.5 % ZnSO4 at 35 and 55 DAS, T6-RDF + 5.0 kg Zn ha-1 + spray of 0.5 % ZnSO4 at 35 DAS, T7-RDF + 5.0 kg Zn ha-1 + spray of 0.5 % ZnSO4 at 35 and 55 DAS, T8-RDF + Zn solubilizer as soil application, T9-RDF + 5.0 kg Zn ha-1 + Zn solubilizer as soil app

Keywords

Soybean, zinc application strategies, nutrient content, uptake and use efficiency.

Conclusion

Zinc is deficient in most of the soils of India, so need to supplement the soil with zinc containing fertilizers. The experimental study revealed that zinc application significantly increases nutrients content, uptake and use efficiencies. And also, data revealed that zinc application significantly increases nutrients status of soil after harvest of crop over absolute control treatment. From the present study concluded that application of RDF + 5.0 kg Zn ha-1 + spray of 0.5% ZnSO4 + 150 ppm salicylic acid at 35 and 55 DAS gives better results in terms of highest nutrients content and uptake (N, P, K and Zn) and use efficiency by soybean.
