Abstract

A field experiment was conducted during the kharif season of 2020 at the Plant Breeding Farm, Department of Genetics and Plant Breeding, Annamalai University to study the effect of seed pelleting and foliar application of seaweed powder and botanical powders on seed quality and yield parameters in black gram [Vigna mungo (L.)] var. VBN10. The seeds were pelleted with seaweed powders and botanical powders viz., Kappaphycusalvarezii, Gracilaria sp, neem leaf powder,arappu leaf powder, moringa leaf powder, custard apple leaf powder, prosopis leaf powder to study the effect on seed quality and yield characteristics like germination percentage, root length, shoot length, seedling length, seedling fresh weight, seedling dry weight, vigour index I, vigour index II, plant height, number of leaves per plant, number of branches per plant, number of nodules per plant, days to first flowering, number of cluster per plant, number of pods per plant, pod weight per plant, pod length, number of seeds per pod, number of seeds per pod, number of seeds per plant, test weight and pod yield per plant. The results showed that black gram seed spelleted with T2 Kappaphycus alvarezii and foliar application @ 5% improved higher seed yield and quality parameters when compared to other treatments and control.
