Nutritional paradigm of vermicompost enhances tolerance to endosulfan in Cicer arietinum

摘要

A nutritional factor in vermicompost has been exploited suitably to stimulate growth of chickpea?Cicer arietinum. It?was?noticed that incorporating 12.5% of vermicompost stimulates the plant in every aspect of growth and development. Germination rate decreased during 10 to 15 days of treatment. However, it becomes identical to the control after 20 days of treatment. The percentage of increase in total length, internode size, emergence of leaf, emergence of flower and number of pod was 13% (40 days treatment), 205% (15 days treatment), 43% (28 days treatment), 58% (65 days treatment) and 600% (80 days treatment), respectively. Similar impact of vermicompost?was also?noticed during growth of the plant in 2.5, 5 and 7.5% of endosulfan. An increase in germination to the extent of 6-fold was also noticed. Total length, internode size, emergence of leaf, emergence of flower and number of pod has been triple (5 days treatment in 15% endosulfan), more than 450% (5 days treatment in 5% endosulfan), more than 550% (23 days of growth in 10% endosulfan), 300% (65 days growth in 10% endosulfan) and 600% (85 days growth in 5% endosulfan). Hence, the results obtained partially support stimulation effect of vermicompost in chickpea plant growth. This can be attributed to, as one of the principles, adopted by?Cicer arietinum?in?remediation of endosulfan.
