Effect of Integrated Nutrient Management on Nutrient Content and Their Uptake by Soybean Crop (Glycine max L.)

Aim: To study the effect of integrated nutrient management practices on nutrient content and uptake by soybean crop (Glycine max L.).

Study Design: Randomized block design.

Place and Duration of Study: One-year field experiment at Research Farm, School of Agriculture, Abhilashi University, Chail Chowk, Mandi, (H.P.), during kharif of 2023.

Methodology: The experiment was conducted with three replications and nine treatments viz. T1= Absolute control, T2= 100% RDF, T3= 100% RDF + Rhizobium, T4 = 75% RDF + 25% N by FYM, T5= 75% RDF + 25% N by Vermicompost, T6= 50% RDF + 50% N by FYM, T7= 50% RDF + 50% N by Vermicompost, T8= 50% RDF + Rhizobium + 25% N by FYM + 25% N by Vermicompost and T9= 100% RDF + Rhizobium + 25% N by FYM + 25% N by Vermicompost.

Results: The study of the data revealed that there is a non-significant effect of integrated nutrient management practices on the content of nitrogen, phosphorus and potassium in grains and straw of soybean crop, whereas, the application of treatment T9 noted the highest content of these nutrients in grains and straw of the soybean crop. Treatment T9 also recorded the significantly maximum uptake of nitrogen, phosphorus and potassium by grains, straw and total uptake by soybean crop, which was statistically at par with treatments T3 and T2. However, the minimum content of nitrogen, phosphorus and potassium in grains and straw along with their uptake by grains, straw and total uptake by soybean crop were found under the treatment T1 during the field experiment.

Conclusion: This study showed that the different integrated nutrient management practices do not affect the content of nutrients in soybean crop significantly, however, it has significantly affected the uptake of nutrients by soybean crop.
