ABSTRACT
Soil exo-enzymes like acid phosphatase, alkaline phosphatase and dehydrogenase activity in groundnut growing soils with the application of mycogenic silver nanoparticles synthesized from Trichoderma viride (GRT-1) was measured after 0 days (at the time of sowing), 15 days and 30 days after sowing. The activity of acid phosphatase, alkaline phosphatase and dehydrogenase was observed to be significantly high at 30 days after sowing compared to control. Physiological parameters like plant height and number of leaves per plant were recorded to be significantly high in groundnut plant growing in silver nanoparticles treated pots at 30 days after sowing compared to control. Among all the treatments, treatment at 150 ppm concentration showed higher values compared to treatment at 100 and 50ppm. The plant height and number of leaves per plant were observed to be increased from 10 days, 20 days and 30 days of sowing. Root and shoot length, fresh and dry weight of groundnut plant were recorded to be significantly higher at 30 days after sowing. Total chlorophyll content was measured in all the treatments and recorded higher values compared to control. Among all the treatments, treatment at 150ppm conc. showed higher chlorophyll content when compared to treatment at 100 and 50ppm. The chlorophyll a was observed to be higher, when compared to chlorophyll b.
Key words: Soil exo-enzymes, acid phosphatase, alkaline phosphatase and dehydrogenase
