Seed treatment is a useful practice for healthy plant growth. Seed priming through controlled hydration and dehydration enhances early germination of mustard seed in less time, even in compacted soil [ 8 ]. The soaking of mustard seeds in % aqueous pyridoxine hydrochloride solution for 4 hours improved germination. The combination of pyridoxine + N 60 P 20 + N 15 P 5 (top dressing) accelerated the crop performance by enhancing seed yield and oil yield by and %, respectively, over the control [ 9 ]. The differential response of varieties for imbibition gives advantage to some of them to germinate early as compared to others. At Hisar, maximum rate of imbibition was reported in “NRCDR-2” (%) and minimum in “NRCDR-509” (%). Such drastic difference in rate of imbibition is important for identification of suitable varieties under abiotic stress conditions namely drought, frost, and temperature abnormalities.
