Among the micronutrients, zinc (Zn) and iron (Fe) deficiency in dietary food are associated with malnutrition symptoms (hidden hunger) which can be overcome through biofortification. The hidden hunger or malnutrition is considered global challenge to human kind. Malnutrition afflicts approximately more than one billion of world’s population in both developed and developing countries. Malnutrition includes diet related chronic diseases as well as nutrient deficiencies which leads to morbidity, reduced physical and mental growth. However, strategies to enhance supplementation of mineral elements and food fortification have not always been successful. Microbial-assisted biofortification attracted much attention recently due to its sustainable and eco-friendly nature for improving nutrient content in many crop. Plant growth promoting microorganisms are known to fortify micro and macro nutrient contents in staple food crops through various mechanisms such as siderophore production, zinc solubilization, nitrogen fixation, phosphate and potash solubilization, etc. Inoculation of potential microorganisms along with fertilizers increase the uptake of mineral elements, yield and growth. Eight microbial isolates were tested for in in vitro ability of zinc solubilization and siderophore production both in plate and broth medium. For zinc solubilization eight microbial isolates and 0.1% of each chemical source in three replications were tested for their in vitro ability of zinc solubilization using Pikovskayas agar media (PKV) containing zinc oxide, zinc carbonate and zinc phosphate as insoluble zinc source. Solubilization potential was assessed both qualitatively and quantitatively under in vitro conditions. For Siderophore production both plate and broth assay using CAS medium was also tested. The promising microbial cultures procured from authentic sources (i.e, All India Network Project on Biofertilizers, Dept of Plant Pathology, VNMKV Parbhani and National Collection of Industrial Microorganisms (NCIM) Pune) were screened for zinc solubilization and siderophore producing capacity under laboratory condition and plant growth promotion in field condition. Two field experiments were conducted during Rabi season of 2020 and 2021 at Research farm, Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani on zinc and iron deficient Vertisol to study the zinc and iron solubilization potential and microbial biofortification in wheat. Experiments consists of ten treatments in three replications and were used in randomized block design. Seed treatment of wheat was done with plant growth promoting rhizobacteria along with Azotobacter chroococcum at the time of sowing with soil application of recommended dose of NPK. Results of lab experiment indicated that, among the insoluble zinc compounds, zinc carbonate supplementation showed the highest zinc solubilization as compared to phosphate and oxide forms of zinc in both plate and broth assay. As such among the microbial inoculants, Pseudomonas striata, Bacillus megaterium and Trichoderma viride reported significantly highest zinc solubilization and maximum reduction in supernatant pH as compared to other microbial isolates in all insoluble zinc compound sources. While in siderophore production Pseudomonas striata, Bacillus megaterium and Bacillus subtilis were significantly superior in both CAS agar plate and broth medium. Results emerged out from field experiments indicated that biometric observations, qualitative parameters, grain and straw yield, soil physic-chemical, biological, microbial properties and enzymatic activities were improved with coinoculation of microbial isolates along with Azotobacter chroococcum. The number of plant tillers were also enhanced with the application of RDF + Azotobacter chroococcum + Pseudomonas striata. The chlorophyll in leaves was found highest with the coinoculation of RDF + Azotobacter chroococcum + Pseudomonas striata. The highest grain and straw yield was noted with inoculation of RDF + Azotobacter chroococcum + Azotobacter chroococcum which was higher as compared to uninoculated control. The highest increased in zinc content in grain over control and only RDF was reported in treatment i.e. inoculation of RDF + Azotobacter chroococcum + Pseudomonas striata (19.52 and 15.76 per cent respectively) and moreover highest increased in iron content in grain over control and only RDF was reported in i.e. inoculation of RDF + Azotobacter chroococcum + Pseudomonas striata (86.08 and 79.74 per cent respectively). At harvest stage DTPA extractable Zn and Fe content of soil was higher in treatment of RDF + Azotobacter chroococcum + Pseudomonas striata and which was followed by RDF + Azotobacter chroococcum + Bacillus megaterium. Biological properties such as dehydrogenase, acid and alkaline phosphatase and microbial population was increased with the inoculation of different plant growth promoting microorganisms as compared to absolute control. The treatment comprised of RDF + Azotobacter chroococcum + Pseudomonas striata followed by RDF + Azotobacter chroococcum +Bacillus megaterium were found significantly effective in enhancing growth, yield, nutrient content and nutrient uptake (specially zinc and iron) in wheat and maintaining the soil health parameters. The microbial inoculation along with RDF resulted into biofortification of wheat grain and straw with Zn and Fe which can explain mitigating the deficiency of these nutrients in human and animals.ThesisItem Open Access Soil fertility status of continuous sugarcane grown area of gangapur taluka of aurangabad district(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2022-11-30) Kacheriya, Snehal Kishor; Gaikwad, G.K.The present investigation was aimed with an object to know the soil fertility status of continuous sugarcane grown area of Gangapur taluka of Aurangabad district.

Sadar, Dist. Balasore, through Department of Soil Science and Agricultural Chemistry College of Agriculture, Badnapur, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, with an objective to study the response of rice (Oryza sativa L.) to soil and foliar and foliar application of Zinc and Iron . The experiment was conducted under Randomized Block Design (RBD) with the 7 treatments and 4 replications i.e., T1-RDF, T2-RDF+Nano Zinc(0.5% foliar spray at 30 DAS ) , T3-RDF+Nano Fe (0.5% foliar spray at 30 DAS) , T4-RDF + Nano Fe+Nano Zn(0.5% foliar spray at 30 DAS) , T5- RDF + ZnSO4(25 Kg/Ha soil application),T6-RDF+FeSO4(25Kg/Ha soil application),T7-RDF+.ZnSO4+FeSO4(25Kg/Ha soil application) . The result emerged out clearly indicated the significantly higher plant height (128.2 cm) at harvest stage with treatment T7: RDF+ZnSo4+FeSo4(25kg/ha soil application) foliar spray among all treatment. The significantly higher number of tillers plants-1 (16.5) at harvest stage recorded by T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The significantly higher number of effective tillers per square meter337) at harvest stage was also recorded by T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The significantly higher number of panicle length (31.2cm) at harvest stage recorded by T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The significantly higher number of grains per panicle(188) at harvest stage recorded by T4 : RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). Significantly maximum grain and straw yield at harvest (47.9 and 62.5 q ha-1) was recorded by treatment T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The significantly maximum test weight (24.2g) was obtained by treatment T4 : RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The quality parameter maximum starch content (86.4%) was obtained by treatment T4 : RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The highest Nitrogen content in grain (1.22%) and straw (0.43%) and total uptake of N (85.38 kg ha-1) was recorded in treatment T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS).. The highest phosphorus content in grain (0.29%) straw (0.111%) and total phosphorus uptake of (20.39 kg ha-1) was recorded in treatment T4 : RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS).. The highest Potassium content in grain (0.38%) and straw (1.48%) and total uptake of K (106.98 kg ha-1) was recorded in treatment T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The highest Zinc content in grain (33.6mgkg-1) and straw (23.7mgkg-1) and total uptake of Zn (301.59g ha-1) was recorded in treatment T4 :RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS). The highest Iron content in grain (62.56mgkg-1) and straw ( 106.20mgkg- 1) and total uptake of Fe (934.83 g ha-1) was recorded in treatment T4 : RDF+NanoFe+Nano Zn(0,5%foliar spray at 30 DAS).Maximum soil available N(310.8 kgha-1),P(15.7kgha-1),K( 142,7 kgha-1),Zn(2.19mgha-1) and Fe (16.7mgha-1) were obtained by treatment T1:Recommended dose of fertilizers.
