Abstract

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

氮、磷、钾对孟加拉国沿海地区大蒜生长和产量的影响

本试验于2021年11月至2022年3月在孟加拉国Noakhali Noakhali科技大学农业研究基地进行，旨在观察氮肥、磷肥和钾肥对大蒜(Allium sativum L. V: BINA Roshun-1)生长和产量的影响。试验采用随机完全区组设计(RCBD)，包括4个处理，3个重复。处理分别为T0(无NPK)、T1 (NPK 70-70-100 kg ha-1)、T2 (NPK 100-100-140 kg ha-1)、T3 (NPK 130-130-180 kg ha-1)，其中N = Nitrogen、P=P2O5、K= K2O。从植株生长的收获阶段记录了植株高度、每株叶片数、叶片长、每株根数、球茎直径、球茎长、每株丁香数、植株全重、球茎鲜重和每公顷新鲜球茎产量等数据。所有记录参数均有统计学意义(p<0.01)。T3(氮磷钾130 ~ 130 ~ 180 kg hm -1)的株高最高(69.57 cm)，而对照T0(不施用氮磷钾)的株高最低(51.40 cm)。处理T3(氮磷钾130 ~ 130 ~ 180 kg ha-1)的单株叶片数最多(9.97)，叶片长(38.10 cm)，单株根数最多(90.83)，鳞茎长(3.30 cm)，鳞茎直径(3.80 cm)，单株丁香数最多(28.97)，植株全重(65.07 g)，鳞茎鲜重(42.50 g)和每公顷鳞茎鲜产量(2.83 t/ha)，而对照T0(不施用氮磷钾)的数据最低。结果表明，在孟加拉国沿海地区，施用氮磷钾肥@ N 130 kg ha-1、P2O5 130 kg ha-1和K2O 180 kg ha-1的大蒜生长和产量较好。阿格利司。力所能及的。鱼类。10(1):53-60
