A field experiment was conducted from April to September in 2018 at Nobogram Agro farm, Noakhali, Bangladesh. The experiment was done to determine the effect of organic and inorganic fertilizers on growth and yield of country bean (Lablab purpureus L.) in Summer Season. The experiment comprises on country bean local variety named ‘Epsha-2’. There were four treatments viz., T1= Control (no fertilizer are used), T2= Inorganic (TSP 0.50 gm/pit + Gypsum 200 gm/pit + MOP 250 gm/pit), T3= Cowdung (5 kg/pit) and T4= FYM (5 kg/pit) and the experiment was laid out in Randomized Complete Block Design (RCBD) with six replications. The parameters of the experiment were the percentage of seed germination, plant height at four-leaf stage (cm), days to first flowering (days), number of pod per plant, individual pod length (cm), pod width (cm) and pod weight (gm).Among all treatments farmyard manure (FYM) was responsible for a higher percentage of seed germination (100%), maximum plant height during four-leaf stage (6.08 cm), accelerated days to first flowering (48 days), increased pod number per plant (220.33), the maximum number of individual pod length (6.87 cm), pod width (2.07 cm) and pod weight (5.53 gm) over other treatments in summer country bean. So the results showed that farmyard manure strongly influenced plant growth and yield component of the country bean. In brief, application of FYM is necessary to increase country bean production in summer season.
