An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, and Mymensingh to study the effect of phosphorus and boron on the growth and yield of var. BARI Jharsheem-3 along with French bean during November 2017 to March 2018. The experiment was comprised of two factors involving number of levels viz. phosphorus had four levels  15, 20, 25 and 35 kg ha^-1 and four levels of boron viz. 0, 0.5, 1.0 and  1.5 kg  ha^-1. Triple super phosphate and Borax were used as source of phosphorus and boron, respectively. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The results exhibited that yield and its contributing characters were significantly influenced by the phosphorus and boron applications. The experimental findings revealed that highest  number of pods per  plant (4.95), pod length (13.06 cm), number of seeds per pod (4.34), and 1000-seed weight (427.99 g), seed yield (1.40 t ha^-1), stover yield (1.76 t ha^-1), biological yield (3.16 t ha^-1) and harvest index (46%) were recorded under phosphorus level at 25 kg ha^-1. The experimental findings also revealed that the highest number of pods per plant (4.91), pod length (14.45 cm), number of seeds  per pod (4.36), and 1000-seed weight (427.22 g), seed yield (1.39 t ha^-1), stover yield (1.68 t ha^-1), biological yield (3.07 t ha^-1) and harvest index (45.27 %) were recorded  under boron level at 1.5 kg ha^-1. In case of  interaction of phosphorus and boron, the highest number of pods  per plant (5.18),  pod length (14.35 cm), number of seeds pod^-1 (4.84), and 1000-seed weight (427.19 g), seed yield (1.86 t ha^-1), stover yield (2.05 t ha^-1), biological yield (3.91 t ha^-1) and harvest index (47.57 %) were recorded under P level at 25 kg  ha^-1  and B level at1.5 kg ha^-1. So it may be concluded that 25 kg P ha^-1 and 1.5 kg B ha^-1 could be applied to obtain higher yield of bean.
