Abstract:
An experiment was conducted at two locations, the roof of the Biotechnology
Department and Agroforestry research farm of Sher-e-Bangla Agricultural University,
Dhaka, Bangladesh during April 2021 to September 2021 to study the effect of
potassium and phosphorus on the growth and yield of okra on rooftop and field. The
experiment was conducted in RCBD design with three replications. The MSTAT-C
computer package was used for processing and analysis of data. The mean differences
were adjusted by Duncan’s Multiple Range Test at 5% level of significance. Three
