Aldrex T enhanced the mean number of groundnut nodules due to in vitro application at a higher than field concentration (6 g/kg groundnut kernels). Dressing at lower and agricultural applications (1.5 and 3, respectively) not only depressed but also considerably delayed nodule formation. This feature was demonstrated by the great losses in nodule number and weight as well. The latter picked up after 11 weeks to equate that of the controls. Interference of the fungicide in nodulation was highly significant at the sixth week of sowing. An insignificant increase in the number of root nodules was recorded at the tenth week of plant growth thus signifying recovery ofRhizobium from aldrex sensitivity. Dressing at 6 g/kg seeds did not affect the number and weight of nodules particularly after the fourth week of groundnut growth. Subsequently a highly significant increase in nodule weight was noticed. Nitrate and nitrite yield of nodules was favourably affected when kernels received twice the agricultural dose when compared with the non-dressed controls.
