Impact of Inorganic Iron and Siderophore Producing Microbes on Growth and Content of Nutrient in Indian Sorrel Leaves (Rumex vasicarias)

Abstract

A pot culture experiment entitled “Biofortification of Iron in Indian Sorel Leaves using Graded Levels of Iron and Siderophore Producing Microbial Cultures” was planned and conducted during summer season of 2021 at Department of soil science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experimental results revealed that significant higher values of biometric observation in 45, 55 DAS and nutrient content a nd uptake in sorrel leaves at after harvest of crop were recorded. The maximum value regarding growth attributes as well as quality parameter was recorded under the treatment of 100% RDF + 60 mg FeSO4 kg-1 soil + Azospirillum lipoferum. In which maximum plant height recorded with 23.14, and 29.44cm, leaves number (10.50 and 21.92) at 45 and 55 DAS respectively, chlorophyll 3.42 mg g-1, fresh leaf yield and dry matter yield (214.33, 30.87 g pot-1) respectively which were superior among the rest of treatments. Moreover, regarding to quality attributes of sorrel leaves via. macro and micronutrient uptake significantly higher under the treatment of 100% RDF + 60 mg FeSO4 kg-1 soil + Azospirillum lipoferum as compared to control (only RDF).
