Performance of different crop species with pointed gourd (Trichosanthes dioica Roxb.)

The experiment was carried out at the research field of Agricultural Research Station, Rajbari, Dinajpur during rabi season of 2014-15 and 2015-16 to find out suitable crop combination for higher productivity and economic return. Six different treatments viz. T 1 = Sole brinjal (75 cm x 60 cm), T 2 = Sole french bean (30 cm x 10 cm), T 3 = Brinjal normal row (100%) + 1 line french bean between brinjal (33%), T 4 = Brinjal normal row (100%) + 2 lines french bean between brinjal (66%), T 5 = Brinjal paired row (100%) + 3 lines french bean between brinjal (40%) and T 6 = Brinjal paired row (100%) + 4 lines french bean between brinjal (53%) were evaluated. The results revealed that the highest mean fruit yield of brinjal (44.26 t ha -1 ) and french bean (20.96 t ha -1 ) was obtained in sole cropping of component crops. Under intercropping, the highest brinjal yield (38.61 t ha -1 ) was recorded in brinjal normal row + 1 line french bean between brinjal, while, the highest french bean yield (16.06 t ha -1 ) in brinjal normal row + 2 lines french bean between brinjal. The highest mean brinjal equivalent yield (58.72 t ha -1 ) and land equivalent ratio (1.50) was also obtained in brinjal normal row + 2 lines french bean between brinjal. The highest gross return (Tk. 4,69,760 ha -1 ), gross margin (Tk. 3,66,440 ha -1 ), and BCR (4.54) were obtained in brinjal normal row + 2 lines french bean between brinjal and the lowest in sole french bean. The overall results indicated that among the intercrop combinations brinjal normal row + 2 lines french bean between brinjal was found suitable for total productivity and economic return of the system.

“…Total productivity can increase significantly as compared to single cropping by making better use of water, nutrients and solar energy (Yildirim and Guvenc, 2005). Alom et al (2013) also reported the brinjal equivalent yields (BEY) in all intercropping systems were found higher than sole brinjal indicating higher productivity of intercropping systems. Similar results were also reported by Suresha et al (2007) in different chilli based intercropping systems.…”

Intercropping is the option of growing more crops in the same piece of land for additional profit and to mitigate the losses or failure of the main crop. Considering this view, an experiment was designed to observe the growth and yield performance of spinach as an intercrop with bottle gourd as leafy vegetable under various planting method to increase productivity and economic return. The study included four planting systems viz; broadcasting spinach with bottle gourd, line sowing spinach with bottle gourd, sole bottle gourd and sole spinach followed by RCB design with three dispersed replications. Based on the growth and yield performance with economic return, intercropping performed better than sole cropping. The higher bottle gourd equivalent yield (15.67 to 28.36 %) was obtained in line sowing of spinach with bottle gourd than sole bottle gourd. The land equivalent ratio (LER) showed a positive influence on intercropping systems compare to monoculture. The maximum gross return (Tk. 430000 ha-1), gross margin (Tk. 325000 ha-1) and BCR (4.10) was obtained from line sowing of spinach with bottle gourd. This practice could be able for better return with the same input and using the same area of land with minimum risk. Bangladesh Agron. J. 2021, 24(2): 91-97

“…Intercropping is a traditional practice in Bangladesh and it increases total productivity per unit area through maximum utilization of land, labour, and growth resources (Ahmed et al, 2013;Islam et al, 2006;Mahfuza et al, 2012). By judicious choice of compatible crops and adopting appropriate planting geometry, inter/intraspecific competition may be minimized resulting in higher total productivity (Alom et al, 2013). Canopy architecture of tall stature crop regulates the availability of light on under storied crop (Faruque et al, 2006).…”

The experiment was conducted at Agronomy Research Field of Bangladesh Agricultural Research Institute, Gazipur, during the rabi season of 2018 to 2019 and 2019 to 2020 to find out the suitable crop combination of spinach (Spinacia oleracea) and red amaranth (Amaranthus cruentus) with brinjal (Solanum melongena) for higher brinjal equivalent yield, monetary advantage and maximize land utilization through intercropping system. Treatments were: T1 = 2 rows spinach (50%) in between two rows of brinjal (100%), T2 = 3 rows Spinach (75%) in between two rows of brinjal (100%), T3 = 2 rows red amaranth (50%) in between two rows of brinjal (100%), T4 = 3 rows red amaranth (75%) in between two rows of brinjal (100%), T5 = Sole brinjal ( 80 cm × 60 cm), T6 = Sole spinach (Line to line 20 cm) and T7 = Sole red amaranth (Line to line 20 cm) were used in the study. All the intercropping combinations showed better performance in terms of brinjal equivalent yield, gross return and benefit cost ratio (BCR) over sole crops. Among the intercropping combinations, 3 row spinach (75%) in between two rows of brinjal (100%) was the most feasible and profitable intercropping system in respect of brinjal equivalent yield (34.72 t ha-1), land equivalent ratio (1.57), gross return (Tk. 6,94,346 ha- 1), gross margin (Tk. 4,59,088 ha-1) and benefit cost ratio (2.95). From the two years, results revealed that all intercropping treatments were productive as compared to sole treatments but 3 rows spinach (line to line 20 cm) 75% in between two rows of brinjal (80 cm × 60 cm) 100% intercropped combination might be agronomically feasible and economically profitable.
