Delineation work was undertaken to evaluate the status of micronutrients in mixed red and black soils of Rewa district (Madhya Pradesh). The district is spread between latitude-24º21'59.9'' N to 24º48'40.9'' N and longitude-81º09'21.8'' E to 82º02'02.2'' E. The mean value of pH, electrical conductivity, organic carbon and CaCO3 in soil were 7.45, 0.21 dSm -1 , 5.03 g kg -1 and 2.83 g kg -1 , respectively. The average Zn, Cu, Fe, Mn and B contents were observed as 0.69, 1.17, 20.87, 14.41 and 1.34 mg kg -1 , respectively. The available Zn, Cu, Fe and Mn showed negative correlation with soil pH, whereas available boron content exhibited positive correlation. Zinc and boron showed positive and significant correlation with organic carbon. Similarly, Zn, Mn and B were found negatively and significant correlation with CaCO3. The results of the study indicated that zinc (Zn : 55.9 %) and iron (Fe: 2.0 %) deficiency are the major disorders in mixed red and black soils of Rewa district of Madhya Pradesh, India.

The present study was carried out during kharif season 2019-20 at the Research Farm, Department of Soil Science & Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh (INDIA), to assess the effect of microbial inoculants on plant attributes and nutrients uptake by soybean in Vertisols. The experiment was laid out under randomized block design (RBD) with three replications. The 15 treatments comprised of different beneficial microbial consortia in possible combinations applied as seed treatments. The crop was supplemented with recommended dose of fertilizers 20 N : 80 P2O5 : 20 K2O kg ha-1. Besides these, two control plots were maintained as fertilized un-inoculated control (FUI) and unfertilized un-inoculated control (UFUI). The findings revealed that the significant improvement were noticed by the application of consortia NPK+EM+PGPR in plant growth attributes of nodulation at 25, 45 & 65 DAS (71, 70 & 59% respectively), over control (9.5, 33.4 & 34.7 nodule plant-1) and its biomass, (62, 69 & 74% respectively),over the control  (0.58, 1.16 & 0.99 g plant-1),  plant height at 25, 45 & 65DAS were increased 61, 40, 41% respectively, over the control (16.20, 34.90 and 44.30 cm) and plant biomass, (48, 62 & 53%), over the control 1.67, 4.73 and 6.1 g plant-1. Similarly, nutrient uptake (seed & stover) were also increased at 25, 45 and 65 stages of crop growth, with 36.6, 34.8 & 51.3% in seed and 66.7, 98.2 & 67.2% in straw respectively over the control (98.5, 63.8, 5.2, and 7.4, 24.9 and 44.4 kg ha-1 respectively). Thus, it may be concluded that the consortium of NPK + EM + PGPR was superior for sustainable crop production and soil health.
