Economic analysis, Grade-wise tuber yield, Planting geometry, Potato, Seed tuber size


The experiment was conducted during rabi 2014-15 and 2015-16 at Punjab Agricultural University, Ludhiana (India) to optimize planting geometry (50 cm × 15 cm, 65 cm × 11.5 cm, 70 cm × 10.7 cm and 75 cm × 10 cm) and seed tuber size (25-35 mm, 35-45 mm, 45-55 mm) for higher seed-grade and total tuber yield of potato (Solanum tuberosum L.). Planting geometry didn't significantly influence the growth and productivity of potato. However, the effect of seed tuber size was significant as large (45-55 mm) and medium (35-45 mm) sized tubers produced higher yield (8.3 and 7.4 t/ha, respectively) of small sized (<35 mm) and medium sized (35-45 mm) (17.3 and 16.6 t/ha, respectively) tubers and the total tuber yield (42.9 and 42.6 t/ha, respectively). In contrast, the highest yield of large sized tubers (>45 mm) (20.2 t/ha) was obtained with small sized seed tubers. The highest net returns (₹ 381.11 thousand/ha) were obtained with medium sized seed tubers as compared to small and large sized seed tubers. Therefore, medium sized seed tubers (35-45 mm) should be used for higher seed-grade and total potato tuber yield as well as better economic returns, irrespective of the planting geometry, under Punjab conditions.
