Abstract

ABSTRACT:
Seeds of Jatropha curcas were subjected to density grading using specific gravity separator into large, medium and small sizes and their germination percentage was recorded during their storage periods. Graded seeds were treated with different organic and inorganic chemicals and were stored under ambient condition in cloth bag were evaluated for seedling characters at bimonthly intervals. Large sized seeds germinated better (88%) than medium sized (69%) and small sized seeds (43%) and biomass production was higher in seedlings produced from larger seeds. The germination rate was decreased to 50% after 6 months of storage in large and medium sized seeds and before 6 months in small sized seeds. Imidachloprid @1.5ml kg-1 + Bavistin @ 2g kg-1 with (T6) and without (T4) polymer and treatment with bavistin @ 2g kg-1(T2) recorded the highest germination per cent and other quality parameters after ten months of storage.
