Abstract:
A Multilocational field research trial was conducted to evaluate potential of iron and zinc solubilizing microorganisms along with graded levels of iron and zinc source on yield and quality of sugarcane under iron and zinc deficient soil at Bhimashankar SSK Ltd., Pune, SM Bhausaheb Thorat SSK Ltd., Ahmednagar, Datta SSSK Ltd., Kolhapur and Pandurang SSK, Ltd., Solapur during 2020-2021 in Maharashtra. The field research trial at each location was conducted under graded levels of Iron and Zinc source (0, 50 and 100%) and iron and zinc solubilizing microorganisms (2.5, 3.75 and 5.0 lit/ha) with three replications. The data revealed that soil application of 12.5 kg FeSO₄ and 10 kg ZnSO₄ ha^-1 by mixing with 500 Kg FYM along with GRDF (250:115:115 kg N: P₂O₅: K₂O and 20 t FYM ha^-1) and drenching of consortium of iron and zinc solubilizing microbial liquid bioinoculant @ 5.0 lit/ha in 500 lit of water at the time of planting can be done for improvement of Iron and Zinc status, saving of 50% recommended dose of Fe and Zn source, higher cane yield (135.65 t/ha) and sugar yield (15.56 t/ha) as compared to control i.e. 100% NPK (110.12 t/ha) and (11.87 t/ha) respectively in Suru sugarcane under iron and zinc deficient soil of Maharashtra.
