Effect of organic seed treatment on growth and quality of direct seeded rice in Tungabhadra command area of Koppal district

Abstract

A lab experiment was conducted at Agricultural Research Station, Gangavathi, under University of Agricultural Sciences, Raichur to know the impact of organic seed treatment on growth and quality of DSR paddy in TBP area of Koppal district Karnataka state during kharif 2021-22 and 2022-23. The experiment was layout in a CRD design having three replications and twenty treatment combinations. There are two genotypes as a first factors and organic seed treatment as second factors. The pooled results concluded that, among the genotypes, Gangavathi sona was recorded significantly higher germination percentage, root length, seedling length and seedling vigour index- I as compared to RNR-15048 variety, where as RNR-15048 have recorded significantly higher shoot length than Gangavathi sona in laboratory conditions. Among the organic seed treatments, seeds soaked in water for 10 Hrs + soaked in cow-dung slurry for 5 hrs and shade dried seeds was recorded significantly higher germination percentage and shoot length as compared to control. Further, significantly higher seedling dry weight (122.0 mg), vigour index-I (2379.0) and vigour index-II (1150.0) was recorded with soaking in khada cloth in sweet flag extract for 30 minutes as compared to control.
