Study on the effect of different pre-sowing seed treatment on seed quality of mustard (Brassica junecea L.)

The experiment was conducted in Post Graduate Laboratory, Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during Rabi season 2018, in order to find out the suitable priming method for Mustard, for different organic and inorganic viz., T0 -Untreated (control), T1 -DH2O-(12hrs), T2 -KNO3 -1% (12hrs), T3 - KNO3 -1% (24hrs), T4 -NaCl-1% (12hrs), T5 -NaCl-1% (24hrs), T6 -200gauss (30min), T7 -400gauss (30min), T8 -100mA (30min), T9 -200guass (30min), T10-neem leaf extract@5%-12hrs and T11-tulsi leaf extract @5%-12hrs. The seeds were taken and hydrated in their solution for their respective time duration and then dried for 12 hrs under shade. It was found that all the priming treatments showed significance difference with the control while highest germination percentage, Field emergence, Days to 50% flowering, Number of siliqua per plant, Number of seeds per siliqua, test weight (gm), Seed yield per plant (gm), and seedling character parameters viz, Germination percentage (%), Root length (cm), Shoot length (cm), Seedling length (cm), Seedling fresh weight (gm), Seedling dry weight (gm), Vigour index-I, Vigour index –II, Speed of germination were observed for seeds treated with 200 gauss(30min) and plant height, number of primary branches per plant showed nonsignificant difference with control. The study helps to improve the seedling character, growth and nodulation and seed yield with the help of seed priming treatments which are effective, economic, non-toxic and eco-friendly sources. | Study on the effect of different pre-sowing seed treatment on seed quality of mustard (Brassica junecea L.)
