Effect of sowing date and row spacing on green pod yield of garden pea

Abstract

Field experiments on garden pea were conducted at the Tuber Crops Research Sub-Centre, Bangladesh Agricultural Research Institute (BARI), Bogura, during the 2015-16 and 2016–17 cropping seasons. The study aimed to evaluate the impact of sowing dates and row spacing on the yield-contributing characteristics and green pod yield of garden pea (cv. BARI Motorshuti-3). The experiment was conducted a split-plot design with three replications, assigning three sowing dates (27 October, 10 November, and 24 November) to the main plots and four row spacings (20 cm, 30 cm, 40 cm, and farmer’s practice) to the sub-plots. Results from the 2015–16 season indicated that sowing on 10 November with a 20 cm row spacing achieved the maximum green pod yield (6.80 t ha⁻¹) and green stover yield (5.65 t ha⁻¹). This was statistically similar to the 24 November sowing at the same 20 cm spacing, which produced 6.71 t ha⁻¹ green pod; 5.58 t ha⁻¹ stover. A similar trend was observed in 2016–17, where the 10 November sowing at 20 cm spacing yielded the highest results (7.08 t ha⁻¹ pod; 5.74 t ha⁻¹ stover), closely followed by the 24 November sowing at 20 cm spacing (7.01 t ha⁻¹ green pod; 5.72 t ha⁻¹ stover). Based on these findings, a sowing window between 10 and 24 November combined with a 20 cm row spacing is recommended to optimize green pod yield of garden pea in the Bogura region.
