Soybean


Mungbean


Peanut


Issues

Site 1 was damaged by pig and chicken – too close to house

Site 2 may have been high fertility (no nitrate test) – soybean does not respond to inoculation under these conditions


Conclusions

Gross margins: peanut ($1,500-2,000/ha) mungbean ($690-871) soybean ($230-300/ha)

Rhizobium inoculation increased peanut GM by $613/ha

Rhizobium inoculation increased mungbean GM by $181/ha

Soybean did not respond to inoculation (see issues) Small farmers have given up on mungbean because

of high harvest and threshing costs and low yields


Thank you
