The experiment was conducted for two consecutive years (2018 and 2019) at Banaras Hindu University, Varanasi. The experiment was designed in randomized block design with twelve treatments replicated thrice. The data indicated that 25 kg ZnSO4.7H2O ha-1 + ZSM significantly increased tillers over other treatments, but 9.8 kg ZnO ha-1 + ZSM improved panicle length, filled spikelet panicle 1 and test weight. The phytic acid content in rice was found superior in control treatment (6.5 g kg-1), whereas significantly reduced in 25 kg ZnSO4.7H2O ha-1+ ZSM treatment. Moreover, the maximum grain yield (5.01 t ha-1), straw yield (7.85 t ha-1), net return (Rs 58.94 ×103 ha-1) and benefit: cost ratio (1.88) was recorded with 9.8 kg ZnO ha-1 + ZSM. The ...

The enzyme was purified by ammonium sulphate precipitation, gel filtration, and ion exchange chromatography, with an overall recovery of 25.9%. The purified enzyme hada 70 kDa molecular weight (MW) confirmed by SDS-PAGE gel analysis. The maximum enzyme activity was reported at 55 °C and pH 7.0. Xylanase activity and stability were improved in the presence of 30% (v/v) n-dodecane, iso-octane, n-decane, and cyclohexane (7 days). The enzyme activity was improved by Co2+, EDTA, and Triton-X-100 while vigorously repressed by Hg2+ and Cu2+. The purified enzyme showed 1.473 mg/mL Km and 654.017 µg/mL/min Vmax values. The distinctive assets of the isolate verified the potential application in the field of biomass conversion into fuel and other industrial processes. Organic solvent-tolerant xylanases can be used for concurrent saccharification ...

A two-year (2018 and 2019) field experiment was performed to study the effectiveness of Zn sources combined with Zn solubilizing microorganisms, ZSM (Acinetobacter calcoaceticus + Pantoea agglomerans) and cow dung, in rice cv. HUR105 in alluvial soil at the Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh. Among various treatments, the treatment (T8) 9.8 kg ZnO ha-1 with ZSM showed better grain and straw yields. However, 25.0 kg ZnSHH ha-1+ ZSM (T6) was found to be statistically comparable to the treatment (T8). The addition of cow dung (CD) decreased the grain yield in T11 ( 9.8 kg ZnO ha-1 + ZSM + 200 kg CD ha-1) and T12 (14.6 kg ZnO ha-1 + ZSM + 200 kg CD ha-1), except the treatment (T10) 4.9 kg ZnO + ZSM + 200 kg CD ha-1. Partial factor productivity of applied Zn varied from 347.2 to 1762.2 and 369.6 to 1855.6...
