Fertilizers and Mixed Crop Cultivation of Chromium Tolerant and Sensitive Plants under Chromium Toxicity.

Dheeba B, Sampathkumar P, Kannan K - J Toxicol (2015)

Bottom Line: Zea mays (maize) and Vigna radiata (green gram) are found to be the chromium (Cr) tolerant and sensitive plants, respectively.Further, the potassium dichromate was used as the source of hexavalent Cr.The results indicated that Cr adversely affects both the growth and yield of plants.

ABSTRACT
Zea mays (maize) and Vigna radiata (green gram) are found to be the chromium (Cr) tolerant and sensitive plants, respectively. In the present paper, we investigate the reduction of the toxicity of Cr in the sensitive plants by the mixed crop cultivation in the field using various amendments. Further, the potassium dichromate was used as the source of hexavalent Cr. The results indicated that Cr adversely affects both the growth and yield of plants. The soil properties vary with Cr and different fertilizer amendments and the yield of both plants were affected by Cr. We conclude that metal accumulation of seeds of green gram was higher than corn and the application of single fertilizer either farm yard manure (FYM) or nitrogen, phosphorous, and potassium (NPK) enhances the growth and yield of both the tolerant and sensitive plants in the mixed crop cultivations.

Mentions: The shoot and root length of green gram plants after harvesting are given in Figure 1(a). The higher shoot (40.16 cm) and root length were recorded in the plants that received both FYM and NPK. There was a drastic reduction in shoot (38%) and root (37%) length of green gram which received Cr alone when it was compared with control. The application of fertilizer amendments increases the growth rate of the plants treated with and without Cr. The order of increase in such growth rate was Cr + NPK, Cr + FYM, and Cr + NPK + FYM.
