Possibilities and potential of Rhizobial inoculants in organic pro- duction of fenugreek in arid and semiarid regions of Rajasthan

Abstract

Arid and semiarid regions are known for erratic rainfall and low productive soils. Fenugreek is one of
the important crop of these areas. These regions are having immense possibilities of organic production of
fenugreek. The possibilities can be explored through use of specific, effective and efficient rhizobial inoculants
for the fenugreek production. In the market commercial cross inoculated rhizobial inoculants are available
which are not specific to fenugreek or a particular variety. Also, the growing awareness of health globally has
led to demand of organically produced seed spices as there are free from synthetic chemical residues and
health hazards and also bear high quality ecofriendly. The use of Rhizobium has proved beneficial in improving
the soil nitrogen and getting higher yield. However, the use of effective Rhizobium cultures as inoculums for
organic production of fenugreek crop has not gained much momentum due to lack of scientific information
and awareness among the growers therefore, it is essential to understand interaction of Rhizobium to specific
variations of fenugreek, bio-ecology and their association as well. Screening of effective Rhizobium strains
for adverse environmental conditions (Drought, salinity and salt, temperature etc) prevailing in Rajasthan,
may require a great attention on rhizobia research. This paper reviews the potential of fenugreek rhizobia
symbiosis and discusses future potential of this crop for use in arid and semiarid regions of Rajasthan.
