Abstract

A laboratory experiment was conducted in a Completely Randomized Design (CRD) with four replications during Rabi, 2020-2021 at Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj. The genetically pure seeds of sorghum var. SPV 1411 (Parbhanimoti) was used for the study. The sorghum seeds primed with treatments (Neem leaf, Parthenium leaf, Azospirillum sp., Pseudomonas fluorescens, Boron, Zinc sulphate) were subjected to germination studies in laboratory, seed germination and seedling growth parameters were recorded. Analysis of variance revealed significant mean sum of squares due to seed priming treatments. The highest germination percentage (95%), root length (14.79 cm), shoot length (19.65cm), seedling length (34.44cm), fresh weight (1.71g), dry weight (0.20g), vigor index 1 (3272) and vigor index 2 (19.23) were observed in T12 (Combination of Azospirillum sp. + Pseudomonas fluorescens + Zinc sulphate + Boron) followed by T11 (

Conclusion

It is concluded from the present investigation of seed treatments with different kind of priming were found affecting significantly different characters of growth under study in sorghum. Priming with T12 (Combination of Azospirillum sp. + Pseudomonas fluorescens + Zinc sulphate + Boron) was found significantly superior which affected all the growth parameters in sorghum in comparison to control and other treatments. Thus, application of Azospirillum sp. + Pseudomonas fluorescens + Zinc sulphate + Boron) is useful for improving seed quality in sorghum. Therefore on behalf of this study suggested combination of bio-inoculants and micronutrients were capable to increase germination and seedling parameters. The use of bio-inoculants is an efficient approach to replace chemicals which are ecofriendly, non-hazardous and non-toxic for sustainable sorghum cultivation. Further investigations under field conditions might be needed to clarify the role of bio-inoculants and micronutrients i
