Abstract:
A pot culture experiment was conducted at the Net I-louse and laboratory of Soil
Science Division in Bangladesh Agricultural Research Institute (BAR!), Joydebpur, Gazipur
during September to December 2007 to evaluate the performance of phosphorus levels and
Thmlyrinzohwm on growth. nodulation, yield, phosphorus, nitrogen content and uptake and
other yield contributing characters of blackgram variety BAR? Mash-I. Bradvrhi :uhiiw,
inoculant (BAR] ltVm-301) was used for the above experiment. 'lucre were ten treatment
combinations with two lircsc4rhjzohjum namely non-inoculated and inoculated and five levels
of phosphorus cã 0. 10, 20. 30 and 40 kg ha with thur replications. Signilicant influences of
phosphorus level were observed in nodulation and yield (seed, pod and stover) and nutrient
content and uptake by seed and other yield contributing characters. Application of
phosphorus up to 20 kg ha'1 progressively increased the values of all the parameters. Further.
higher doses application of phosphorus decreased the value of all of these parameters.
