dc.description.abstractIn the present investigation, two seed lots of four varieties viz., HC2-85, HC3-8, HC98-64 and FS-68 were taken and grouped into two seed lots on the basis of germination percentage. The lot which showed germination percentage above the Indian Minimum Seed Certification Standard (75.0 per cent) of cowpea were termed as good seed lot (L1) and which showed germination percentage below the Indian Minimum Seed Certification Standard of cowpea were termed as marginal seed lot (L2). All the eight seed lots were given the five pre-sowing seed treatments viz., hydration-dehydration (for 4 h), GA3 (50ppm), GA3 (100ppm), KNO3 (0.1%) and hydration-dehydration + thiram @ 3g/kg seed treatments and compared with control. The results revealed that marginal seed lot (L2) showed more improvement than good seed lot (L1) after pre-sowing seed treatments under laboratory and field conditions. Among the varieties, HC3-8 showed maximum improvement in standard germination while HC2-85 showed maximum improvement in seedling establishment. The results also predicted that the treatment GA3 (100 ppm) followed by hydration dehydration + thiram @ 3g/kg seed was found most effective in all the parameters except in root length in which hydration dehydration + thiram @ 3g/kg seed was found most effective among all the treatments.en_US
