Abstract:

Phosphorus is a major limiting factor for plant growth particularly in the tropics and subtropics areas. It play an important role in many biochemical process viz., energy storage and transfer, cell division, cell enlargement and several other processes in plants. The availability of P to plants is a problem owing to its slow diffusion and high fixation in soils. Due to low solubility and mobility in soil, phosphorus use efficiency is very low ranges from 10-20% in normal soil. On the other hand, due to expansive nature and larger gap between production and consumption its use is restricted by farmers. Phosphorus efficient plants could not meet the need for P fertilizer hence, they are not a sustainable solution for such problems. Thus, phosphorus utilization efficiency can be improved by using certain management practices. Among these practice, rhizospheric management strategies is one of most important technique to increase P use efficiency by manipulating root growth and rhizosphere processes. This management strategies concerns mainly with manipulation in root system, microbial activity, rhizo environment and cropping system which can improves the efficient utilization of P in natural environment.
