Abstract

Soybeans are a large oil seed crop and legume that may be produced in a variety of soils and climates. A crucial micronutrient needed by humans, animals, and plants is zinc. As there is a greater concern to sustain the deteriorating soil health due to indiscriminate use of chemical fertilizers and hence exerting the lack of beneficial microbes in the soil. Therefore, lack of essential nutrients in the soil is a global concern for the growth of food crops. The present investigation was carried out during kharif 2021 on Research farm of R.A.K. College of Agriculture, Sehore (M.P.) to evaluate the effect of conjoint use of Bio-NPK and Bio-Zn with chemical fertilizers on nutrient uptake of soybean. The studies have been found beneficial to fetch the more production of the crop along with improving the soil health. The experiment was laid out in Randomized Block Design with seven treatments in combinations in three replications consisting of treatments T1: Control; T2: 100% Recommended dose of fertilizers (RDF); T3: 75% RDF; T4: 75% RDF + Bio-Zn; T5: 75% RDF + Bio-NPK; T6: 75% RDF + Bio-Zn + Bio-NPK; T7: 75% RDF + Rhizobium japonicum. Revealed that nutrient content and uptake was also increased with the inoculation of microbial cultures as compared to uninoculated control and highest N uptake was found in treatment 100% RDF (74.95 Kg ha-1) and it was at par with 75% RDF + Bio-NPK, 75% RDF + Bio-Zn + Bio-NPK and 75%RDF + Rhizobium japonicum which uptake 69.92, 70.16 & 66.13 Kg ha-1. Highest P uptake found in 100% RDF (5.61 kg ha-1) however it was at par with 75% RDF + Bio-Zn + Bio-NPK which uptake 5.05 Kg ha-1. Highest k uptake found in 100% RDF (57.96 kg ha-1) however it was at par with 75% RDF + Bio-NPK and 75% RDF + Bio-Zn + Bio-NPK which uptake 52.62 & 50.72 Kg ha-1 by soybean crop at harvest and highest Zn and Fe uptake was found in 75% RDF + Bio-Zn + Bio-NPK (0.0408 & 0.0470 kg ha-1) however these were at par with75% RDF + Bio-Zn which uptake 0.0371 & 0.0430Kg ha-1.

Keywords

Bio-Zn, Bio-NPK, Chemical Fertilizers, Black Soil, Soybean

Conclusion

The present study concluded that 100% RDF (20:60:20:20) is more effective in the uptake of N, P and K of the crop and 75% RDF + Bio-NPK + Bio-Zn effective in Zn and Fe uptake. Therefore, the study would definitely beneficial to produce optimum yield, quality and boost up the sustainable soil health.
