Abstract

The field experiment was conducted at Agronomy Research Field, Joydebpur and RARS, Burirhat, Rangpur, BARI during Rabi season of 2018-2019 and 2019-2020 to find out suitable combination of sorghum and gardenpea intercropping for higher productivity and monetary advantage. Treatments included in the experiment were: T1 = Sorghum normal row (SNR) + 1 row gardenpea (GP), T2 = SNR + 2 rows GP, T3 = Sorghum paired row (SPR) + 2 rows GP, T4 = SPR + 3 rows GP, T5 = SPR + 4 rows GP, T6 = Sole sorghum (60 cm ´ 10 cm) and T7 = Sole GP (30 cm ´ 10 cm). Light availability on gardenpea decreased with the increase of shade produced by sorghum canopy over the time up to 60 DAS. The lowest light availability on gardenpea was observed in T2 treatment and the highest was observed in sole gardenpea (T7) followed by T3 treatment in both the years. The maximum grain yield of sorghum was observed in T6 and it was decreased (6-10% in 2018-2019 and 1-12% in 2019-2020) at Joydebpur and (5-11% in 2018-2019 and 6-14% in 2019-2020) at Burirhat. The highest sorghum equivalent yield (SEY) of 10.93 t ha-1 in 2018-2019 and 12.02 t ha-1 in 2019-2020 at Joydebpur and 12.06 t ha-1 in 2018-2019 and 11.77 t ha-1 in 2019-2020 at Burirhat and also the highest land equivalent ratio (LER) of 1.77 in 2018-2019 and 1.93 in 2019-2020 at Joydebpur and 1.79 in 2018-2019 and 1.81 in 2019-2020 at Burirhatwere observed in T5 treatment. The highest gross margin of Tk.146600 ha-1 in 2018-2019 and Tk.168400 ha-1 in 2019-2020 at Joydebpur and Tk. 169200 ha-1 in 2018-2019 and Tk.163400 ha-1 in 2019-2020 at Burirhat and also the benefit cost ratio (BCR) of 3.04 in 2018-2019 and 3.34 in 2019-2020 at Joydebpur and 3.35 in 2018-2019 and 3.27 in 2019-2020 at Burirhat were also found in the same treatment. The results revealed that sorghum paired row + 4 rows gardenpea might be agronomically feasible and economically profitable for sorghum + gardenpea intercropping system at Joydebpur and Burirhat region.

种植制度对豌豆与高粱间作的影响

在2018-2019年和2019-2020年的拉比季节，在农学研究基地、Joydebpur和RARS、Burirhat、Rangpur、BARI进行了田间试验，以找出高粱和栀子豆间作的合适组合，以提高生产力和经济效益。试验处理为:T1 =高粱正常行(SNR) + 1行栀子豆(GP)， T2 = SNR + 2行GP, T3 =高粱配对行(SPR) + 2行GP, T4 = SPR + 3行GP, T5 = SPR + 4行GP, T6 =高粱鳎(60 cm´10 cm)和T7 =鳎GP (30 cm´10 cm)。在60 DAS内，随着高粱冠层遮荫量的增加，栀子豆的光效降低。两个年份的光效均以T2处理最低，单粒栀子(T7)最高，T3处理次之。高粱的最高产量在T6观察到，在Joydebpur和Burirhat分别下降(2018-2019年6-10%和2019-2020年1-12%)和(2018-2019年5-11%和2019-2020年6-14%)。T5处理的高粱等效产量最高，分别为2018-2019年的10.93 t ha-1和2019-2020年的12.02 t ha-1，以及2018-2019年的12.06 t ha-1和2019-2020年的11.77 t ha-1;土地等效比最高，分别为2018-2019年的1.77和2019-2020年的1.93，以及2018-2019年的1.79和2019-2020年的1.81。在相同的处理中，Joydebpur的最高毛利率为2018-2019年的146600 ha-1和2019-2020年的168400 ha-1, Burirhat的最高毛利率为2018-2019年的146600 ha-1, 2018-2019年的169200 ha-1和2019-2020年的163400 ha-1，并且Joydebpur的效益成本比(BCR)为3.04,2019-2020年为3.34,Burirhat的2018-2019年为3.35,2019-2020年为3.27。结果表明，在Joydebpur和Burirhat地区，高粱配行+ 4行豌豆间作在农艺上是可行的，经济上是有利的。孟加拉国阿格龙。[j] . 2020, 23(2): 59-68
