Effect ok sulphur, bradyriiizobium inoculation, moisture content of seed and storage container on the vigour index of groundnut seed

Abstract

Abstract : The study was aimed to determine the effect of sulphur and Bradyrhizobiwm fertilized seed at different initial moisture content of seed and storage container on the vigour index of groundnut seed. Results revealed that the vigour index increased with the doses of sulphur up to 60 kg S/ha in storage but the seed obtained from inoculation failed to check the deterioration. Seed obtained from 60 kg S/ha stored in polythene bags retained the vigour index up to the standard level. Least initial moisture content of seed (7.25%) produced from the above doses of fertilizer elements also played a vital role in keeping the quality of . stored seed. Results of vigour index indicated that groundnut seed obtained from sulphur and Brcidyrhizobium fertilization during production and stored in polythene bags can retain better seed quality, provided that the seed were dried to a safe moisture level of 7.25%.
