Effect of nitrogen, phosphorus and potassium on the growth and yield performance of garlic (Allium sativum L.) in coastal zone of Bangladesh

The experiment was carried out at Agricultural Research Field, Noakhali Science and Technology University, Noakhali, Bangladesh during the period from November 2021 to March 2022, observe effect of nitrogen (N), phosphorus (P) potassium (k) fertilizer on growth yield garlic (Allium sativum L. V: BINA Roshun-1). laid in a Randomized Complete Block Design (RCBD) comprising four treatments with three replications. were T0 (no NPK), T1 (NPK 70-70-100 kg ha-1), T2 100-100-140 T3 130-130-180 here, N = Nitrogen, P=P2O5, K= K2O respectively. Data recorded harvesting stages plant height, number leaves per plant, leaf length, roots bulb diameter, cloves whole weight fresh hectare. All parameters statistically significant (p<0.01). highest height (69.57 cm) ha-1) whereas lowest (51.40 obtained control NPK). maximum (9.97), length (38.10 cm), (90.83), (3.30 diameter (3.80 (28.97), (65.07 g), (42.50 g) hectare (2.83 t/ha) found treatment data Observing results, it can be stated that application NPK @ 130 ha-1, P2O5 ha-1 180 for cultivation gave better coastal zone Bangladesh.
