摘要
在2016年和2017年的Kharif季节，在孟加拉国农业研究所的Joydebpur、Jashore和Ishurdi农场进行了田间试验，以寻找杂交玉米和印度菠菜作为间作系统的合适组合，从而获得更高的生产力和货币优势。试验中包括的处理为：T1=杂交玉米正常行（75cm×20cm）+1行印度菠菜（株间25cm），T2=杂交玉米成对行（37.5cm/150cm×20cm）+1行印度人菠菜（株对25cm）；T3=杂交玉米对行（37.5cm/150cm×20cm）+2行印度人菠菜，T4=杂交玉米成对行（37.5厘米/150厘米×20厘米）+3行印度菠菜（株对株25厘米），T5=独播玉米（75厘米×20 cm），T6=独播印度菠菜（40厘米×25厘米）。玉米产量在单一作物中最高，但由于玉米和印度菠菜间作对生长资源的特定竞争，Joydebpur的玉米产量下降了1.0%至12.6%，Jashore的玉米产量降低了5.2%至17.1%，Ishurdi的玉米产量减少了13.4%至22.2%。所有间作处理均表现出比单一玉米作物更好的表现。最高的玉米当量产量（2016年和2017年，Joydebpur分别为19.22和18.80 t ha-1，Jashore分别为13.30和11.58 t ha-1和Ishurdi分别为11.23和11.10 t ha-1），在杂交玉米对行+3行印度菠菜中观察到毛利率（Joydebpur分别为196300和192000 ha-1，Jashore分别为111130和85330 ha-1，Ishurdi分别为88450和86500 ha-1）和效益成本比（Joydebbur分别为3.13和3.07，Jashor分别为2.26和1.97，Ishurdy分别为2.11和2.08）间作。在同一处理中也发现了最高的土地当量比（2016年和2017年，Joydebpur的土地当量率分别为1.32和1.39，Jashore的土地当量比率分别为1.50和1.47）。另一方面，在Ishurdi，MNR+1行ISP处理的LER最高（2016年和2017年分别为1.34和1.35），其次是MPR+3行ISP处理。结果表明，在Joydebpur、Jashore和Ishurdi，杂交玉米对行+3行印度菠菜和杂交玉米正常行+1行印度菠菜间作系统可能具有经济效益。孟加拉国Agron。J.2022，25（1）：75-82
Effect of Planting System on Productivity of Hybrid Maize-Indian Spinach Intercropping System
A field experiment was undertaken at Joydebpur, Jashore and Ishurdi Farm of Bangladesh Agricultural Research Institute during Kharif seasons of 2016 and 2017 to find out suitable combination of hybrid maize and Indian spinach as intercropping system for higher productivity and monetary advantage. Treatments included in the experiment were: T1 = Hybrid maize normal row (75 cm × 20 cm ) + 1 row Indian spinach (plant to plant 25 cm), T2 = Hybrid maize paired row (37.5 cm/150 cm × 20 cm) + 1 row Indian spinach (plant to plant 25 cm), T3 = Hybrid maize paired row (37.5 cm/150 cm × 20 cm) + 2 rows Indian spinach (plant to plant 25 cm), T4 = Hybrid maize paired row (37.5 cm/150 cm × 20 cm) + 3 rows Indian spinach (plant to plant 25 cm), T5 = Sole maize (75 cm × 20 cm) and T6 = Sole Indian spinach (40 cm × 25 cm). Grain yield of maize was the maximum in sole crop but it was decreased 1.0 to 12.6% at Joydebpur, 5.2 to 17.1% at Jashore and 13.4 to 22.2% at Ishurdi due to inter specific competition for growth resources among maize and Indian spinach due to intercropping. All intercropping treatments showed better performance than sole maize crop. The highest maize equivalent yield (19.22 and 18.80 t ha-1 at Joydebpur, 13.30 and 11.58 t ha-1 at Jashore and 11.23 and 11.10 t ha-1 at Ishurdi in 2016 and 2017, respectively), gross margin (Tk. 196300 and Tk. 192000 ha-1 at Joydebpur, Tk. 111130 and Tk. 85330 ha-1 at Jashore and Tk. 88450 and Tk. 86500 ha-1 at Ishurdi in 2016 and 2017, respectively) and benefit cost ratio (3.13 and 3.07 at Joydebpur, 2.26 and 1.97 at Jashore and 2.11 and 2.08 at Ishurdi in 2016 and 2017, respectively) were observed in hybrid maize paired row + 3 rows Indian spinach intercropping. The highest land equivalent ratio (1.32 and 1.39 at Joydebpur and 1.50 and 1.47 at Jashore in 2016 and 2017, respectively) was also found in the same treatment. On the other hand, at Ishurdi, the highest LER (1.34 and 1.35 in 2016 and 2017, respectively) was observed in MNR + 1 rows ISP treatment followed by MPR + 3 rows ISP treatment. The results revealed that hybrid maize paired row + 3 rows Indian spinach and Hybrid maize normal row + 1 row Indian spinach intercropping might be economically profitable for hybrid maize + Indian spinach intercropping system at Joydebpur, Jashore and Ishurdi.
