Abstract/ Executive Summary:

The experiment was conducted at the Agronomy research field of BARI during the Rabi season of 2013-14 to find out appropriate potato seed (cut or whole tuber) and spacing for higher potato production. Three planting systems viz. single eye planting (30 cm × 10 cm), single eye double row zig zag system (10 cm/30 cm × 10 cm) and half cut tuber (30 cm × 25 cm) were compared with recommended planting system (60 cm × 25 cm). The highest tuber yield (30.79 t/ha), gross return (TK 307900 /ha) and gross margin (TK 151734/ha) were obtained from treatment single eye double row zig zag planting system (10 cm/30 cm × 10cm). But the highest BCR (1.97) was obtained from both single eye planting systems. The results revealed that both single eye planting systems with 30 cm × 10 cm and 10 cm/30 cm × 10cm spacing would be better for getting higher potato yield and economic return than recommended planting system.

Keywords: Planting method, Tuber yield, Potato

Location: Agronomy research field of BARI, Gazipur

Start Date: 25-11-2013

End Date: 25-02-2014

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

To find out appropriate potato seed (cut or whole tuber) and spacing for higher potato production in char land eco-system as well as other land.

Methodology:

The experiment was conducted at the Agronomy research field of BARI, Gazipur during the Rabi season of 2013-2014. The trial was laid out in RCB design with three replications. The variety was Cardinal (BARI Alu-8) and the unit plot size was 3m × 3m. Three planting systems viz. T₂ : Single eye planting (30 cm × 10 cm), T₃ : Single eye double row zig zag system (10 cm/30 cm × 10 cm) and T₄ : half cut tuber (30 cm × 25 cm) were compared with T₁ : Recommended planting system (60 cm × 25 cm). The potato tuber was planted on 25 November 2013. Chemical fertilizers were applied at the rate of 180-40-180-20-4-1.2 kg/ha of NPKSZn and B, respectively (FRG, 2012). Half of NK and full dose of other fertilizers were applied as basal. Rest of NK was top dressed at 30 days after planting (DAP) followed by irrigation. Another irrigation was provided at 60 DAP. One weeding was done at 45 DAP. Fungicide (Ridomil gold) was sprayed 10-day intervals from 35 to 75 DAP to prevent late blight disease. The crop was harvested on 25 February, 2014 (92 DAP). Data on yield and yield components were recorded and analyzed statistically and the means were adjusted using LSD test. Economic analysis was also done considering local market price of potato.
