Relationships between relative growth rate, leaf nitrogen and leaf phosphorus in 17 herbaceous species of tropical dry deciduous forest of vindhyan highlands

The present study analyses relationship between relative growth rates (RGR), leaf nitrogen and leaf phosphorus. A range of leaf attributes was measured for 17 herbaceous species in four contrasting habitats fortnightly from   July to September (2006-2007). All herbaceous vegetation in 5 randomly located plots within each of four sites was clipped at ground level and analyzed fortnightly during the study period. RGR shows positive relationship with leaf nitrogen and leaf nitrogen.  This result depicts the pivotal role of the combination of phosphorus and nitrogen in growth-related processes.
