Abstract:
An experiment was conducted at the experimental field of the farm of Sher-e-Bangla
Agricultural University during the period from March to june (kharif season) of 2020
to study the effect of cowdung and inorganic fertilizers on growth and yield of
mungbean (BARI Mung 6). The experiment was laid out in Randomized Complete
Block Design (RCBD) with three replications. The 7 treatment combinations of
cowdung manure and inorganic fertilizer were T

80% of optimum dose of inorganic fertilizer and it was statistically disimilar with the
treatment of 40% cowdung manure + 60% of optimum dose of inorganic fertilizer. It
was observed that, for the above parameters; 80% optimum dose of inorganic fertilizer
+ 20% of optimum dose of Cowdung showed better results than sole 100% inorganic
fertilizer. Lowest values for all of the growth and yield parameters obtained from the
treatment using control.
