INFLUENCE OF PLANTING METHODS AND SPACING ON YIELD AND QUALITY OF RADISH SEED

Abstract

An experiment was carried out to study the influence of planting methods and spacing on yield and quality of radish seed at the experimental field of Sher-e-Bangla Agricultural University (SAU), from November 2021 to March 2022. Three planting methods viz. M 1

= Direct sowing of seed, M 2 = 1/3 cutting of root and M 3 = 2/3 cutting of root were comprised with plant spacings viz., S 1 = 30 cm × 20 cm, S 2 = 30 cm × 30 cm, S 3 = 30 cm × 40 cm. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Different planting methods showed significant variation for growth, yield contributing parameters, yield and quality parameters of radish. The planting method M 1 (Direct sowing of seed) showed significantly highest seed yield plant -1 (10.87 g) and seed yield ha -1 (1234.00 kg) compared to M 2 (1/3 cutting of root) and M 3 (2/3 cutting of root) treatment. M 1 (Direct sowing of seed) also showed the best quality seeds considering highest germination percentage (88.43%) and vigor index (1434.57) whereas M 3 (2/3 cutting of root) treatment gave the minimum results. Different plant spacing of radish showed significant variation for growth, yield contributing parameters, yield seed quality parameters. The highest seed yield ha -1 (1283.33 kg) was recorded from the plant spacing S 1 (30 cm × 20 cm) while the plant spacing S 3 (30 cm × 40 cm) spacing gave the significantly highest germination percentage (89.00%) and vigor index (1611.74). The treatment combination of M 1 S 3 gave the highest number of pods plant -1 (82.13), number of seeds pod -1 (6.31), dry weight plant -1 (153.70 g) and seed yield plant -1 (13.81 g) but the highest seed yield ha -1 (1386.00 kg) was recorded from the treatment combination of M 3 S 1 but the lowest seed yield ha -1 (841.90 kg) was recorded from M 3 S 3 . The treatment combination of M 3 S 1 gave the maximum germination percentage (90.40%) and vigor index (1722.12) whereas M 3 S 1 gave the minimum results. From the above results, it can be concluded that among the planting methods, M 1 (Direct sowing of seed) performed the best regarding growth, seed yield and seed quality. Considering plant spacing, S 1 (30 cm × 20 cm) performed the highest seed yield whereas S 3 (30 cm × 40 cm) was the best for quality seeds production.
