Effect of Nitrogen Treatment and Seasonal Variation on Biomass Production in Dalbergia S1Ssoo Seedlings

Effect of four different nitrogen treatments i.e., 0, 50, 100 and 200 Kg N/ha and seasonal variations on biomass production was studied in Dalbergia sissoo seedlings in pots. An increase due to different nitrogen treatments on the leaf, stem and root biomass was observed as compared to control. On the basis of the pooled average values, maximum and minimum leaf biomass was recorded during rainy and winter seasons, whereas, stem and root biomass in winter and summer seasons respectively.
