Abstract

An experiment was conducted at the research field of Horticulture Research Centre, BARI, Gazipur during Rabi season of 2012-13 to 2014-15 to evaluate the yield and yield attributes of Marigold (var. BARI Marigold-1) to different doses of N, P and K fertilizers and to find out the optimum and economic doses of NPK for maximizing flower yield. Eleven treatments as T 1 , T 2 , T 3, , T 10 and T 11 comprising with four levels of fertilizer nutrients each of N (0, 60, 90 and 120 kg ha -1 ), P (0, 30, 40 and 50 kg ha -1 ) and K (0, 60, 90 and 120 kg ha -1 ) along with a blanket dose of 2 kg B and 4 kg Zn ha -1 . The experiment was conducted assigning the treatments in a randomized complete block design with three replications. Flower yield and yield attributes of marigold significantly increased with NPK fertilizer for all three years. The significantly highest flower yield (22.25, 27.38 and 25.15 ton ha -1 ) was obtained from T 3 treatment applying the nutrients N 90 P 40 K 90 kg ha -1 along with blanket dose of 2 Kg B and 4 kg Zn ha -1 for the years 2012-13, 2013-14 and 2014-15, respectively which was statistically identical with T 4 treatment (N 120 P 40 K 90 kg ha -1 ) for the year 2012-13, but significantly different from all other treatments for the years 2013-14 and 2014-15, respectively. Flower yields were increased in T 3 treatment (N 90 P 40 K 90 kg ha -1 ) by 81.34, 62.53 and 49.53%; 146.00, 119.39 and 108.84% and 121.20, 92.13 and 84.11% over their control in respect to the years 2012-13, 2013-14 and 2014-15. The highest benefit-cost ratio 7.14 was obtained from T 3 (N 90 P 40 K 90 kg ha -1 ) followed by T 4 (6.53) treatment. From the quadratic regression equation averaging three years data the optimum and economic doses 103.75 and 102.44 kg N; 36.67 and 36.31 kg P and 90.10 and 88.43 kg K, respectively were found which could be recommended for marigold production in Grey Terrace Soil of Joydebpur under AEZ 28.

氮、磷、钾肥对万寿菊产量及产量性状的影响

本试验于2012-13 ~ 2014-15拉比季在加济浦尔BARI园艺研究中心研究场进行，评价了不同剂量N、P、K肥对万金菊(BARI Marigold-1)产量和产量属性的影响，找出了实现花产量最大化的最优经济氮磷钾用量。11个处理分别为t1、t2、t3、、t10和t11，包括4个水平的肥料养分，分别为N(0、60、90和120公斤公顷-1)、P(0、30、40和50公斤公顷-1)和K(0、60、90和120公斤公顷-1)，以及2公斤B和4公斤Zn(公顷-1)。试验采用完全随机区组设计，3个重复。施用氮磷钾能显著提高万寿菊的花朵产量和产量性状。明显花产量最高(22.25、27.38和25.15吨公顷1)获得了从T 3治疗应用养分N 90 P 40 K 90公斤公顷1毯子剂量的2公斤B和4公斤锌公顷1年2012 - 13,2013 - 14和2014 - 15日分别是统计与T 4治疗(N 120 P 40 K 90公斤公顷1)2012年- 13,但是明显不同于所有其他治疗2013 - 14和2014 - 15年,分别。t3处理(N 90 P 40 K 90 kg ha -1)花产量分别提高81.34%、62.53%和49.53%;2012-13年、2013-14年和2014-15年分别比对照高146.00、119.39和108.84%、121.20、92.13和84.11%。效益成本比最高的处理是t3 (N 90 P 40 K 90 kg ha -1)，为7.14，其次是t4(6.53)。利用二次回归方程对3年数据进行平均，得出最佳施氮量为103.75 kg和102.44 kg;在AEZ 28条件下，乔伊德布尔灰色阶地土壤适宜种植万金菊的磷含量分别为36.67和36.31 kg，钾含量分别为90.10和88.43 kg。农学家2017;15 (1) 101 - 109
