Foliar fertilization of nitrogen in mungbean: influence of rate and frequency of application
1991
Hamid, A. (Institute of Postgraduate Studies in Agriculture, Salna, Gazipur (Bangladesh). Dept. of Agronomy)
The influence of rate and frequency of foliar N fertilization on the yield performance and nutrient uptake of mungbean had been evaluated in a series of control excepting the treatment with 20 mg N l(1). A concentration of 10 mg N l(-1) was most beneficial to pod and seed development than the higher or lower concentrations. Spraying N at around flowering caused significant yield increase but application twice (at around flowering and at late reproductive phase) gave significantly greater seed yield than any single application. Field experiment also confirmed that foliar N at 10 mg l(-1) applied twice in the reproductive phase gave greater yield advantage.
