Abstract

A field experiment was conducted at the research field of Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI) Gazipur under AEZ-28 during Rabi season of 2017-18 and 2018-19 to determine the suitable combination of nitrogen (N), phosphorus (P), potassium (K) and sulphur (S) for improving growth and cut flower bunch yield of gypsophila. There were 15 treatment combinations comprising four levels of nitrogen (0, 70, 100 and 130 kg ha-1), four levels of phosphorus (0, 20, 40 and 60 kg ha-1), four levels of potassium (0, 60, 90 and 120 kg ha-1) and four levels of sulphur (0, 10, 20 and 30 kg ha-1) along with a blanket dose of Zn3B1.5 kg ha-1 and cow dung 5 t ha-1. The experiment was laid out in randomized complete block design with three replications. The combination of N100P40K60S20 kg ha-1 produced significantly higher cut flower bunch yield. The said treatment produced the maximum mean cut flower bunch yield of 185010 nos. ha-1 which was 76.9% higher over control (N0P0K0S0). The maximum number of branches per plant (7.12 nos.) and maximum opened flower per plant (60.2 nos.) were recorded from the treatment combination of N100P40K60S20 kg ha-1. Cost and return analysis indicated maximum net return and highest benefit cost ratio (1.91) was estimated from the same treatment. The results suggest that combined application of 100-40-60-20 kg ha-1 of N-P-K-S including 3 kg Zn ha-1, 1.5 kg B ha-1 and 5 t ha-1 cowdung can improve the growth and cut flower bunch yield of gypsophila. From the regression analysis, the optimum treatment combination was calculated as N91.8P44.0K80.7S18.7 kg ha-1 for experimental area. Therefore, the optimum combination package N91.8P44.0K80.7S18.7 kg ha-1 along with the blanket dose of Zn3B1.5 kg ha-1 and 5 t cowdung ha-1 may be recommended for gypsophila cut flower cultivation in Gazipur area.

Gypsophila Paniculata的肥料管理
在2017-18和2018-19拉比季节,在孟加拉国农业研究所(BARI)加齐浦尔园艺研究中心(HRC)的研究场里,通过AEZ-28大田试验,确定氮(N)、磷(P)、钾(K)和硫(S)的适宜组合对gypsophila生长和切花产量的促进作用。共有15种处理组合,包括4个氮水平(0、70、100和130 kg ha-1), 4个磷水平(0、20、40和60 kg ha-1), 4个钾水平(0、60、90和120 kg ha-1)和4个硫水平(0、10、20和30 kg ha-1),外加Zn3B1.5 kg ha-1和5 t ha-1牛粪的总剂量。试验采用随机完全区组设计,设3个重复。N100P40K60S20 kg ha-1组合可显著提高切花束产量。该处理的平均切花产量最高为185010株ha-1,比对照(N0P0K0S0)提高了76.9%。N100P40K60S20 kg ha-1处理的单株最大枝数为7.12朵,单株最大开花数为60.2朵。成本与收益分析表明,相同处理的净收益最大,收益成本比最高(1.91)。结果表明,施用100-40-60-20 kg hm -1 N-P-K-S(含3 kg Zn hm -1、1.5 kg B hm -1和5 t hm -1牛粪)可促进gypsophila的生长和切花产量。通过回归分析,计算出试验区最佳处理组合为N91.8P44.0K80.7S18.7 kg ha-1。因此,在加济浦尔地区,推荐使用N91.8P44.0K80.7S18.7 kg ha-1、Zn3B1.5 kg ha-1和5 t牛粪ha-1的最佳组合包装。孟加拉国J.
