Abstract
Okra (Abelmoschus esculentus (L.) Moench) was used as test crop in a
research trial to assess the impact of organic amendments (compost and
farmyard manure) on germination and yield under application of
chromium (Cr) stress. The no. of treatments applied was 10 while 3
replicates were used for each treatment. For inducing Cr stress, K2Cr2O7
(potassium dichromate) solution of 50 mg/Kg concentration was applied
to the soil. Cr treated and untreated soil samples were amended with
compost and farmyard manure at 2.5 % and 5 %. It was demonstrated
that in okra when compared with control, the sugar content and
germination parameters were affected adversely by Cr application. The
treatments of compost at 5 percent and farmyard manure at 2.5 percent
positively affected the yield in both Cr treated and untreated plants. In
comparative analysis compost appeared as more beneficial for okra than
farmyard manure. Overall, the application of compost at 5 percent was
found to be effective in improving yield characters, chlorophyll and sugar
contents of Cr affected okra plants
