rice transplanting spacing row plant distance tillers

The recommended spacing for transplanted paddy is generally 20 cm between rows and 15 cm between plants, with 2 to 3 seedlings per hill for medium duration varieties. For long duration or low fertility conditions you can keep 20 by 20 cm, and for very fertile, high tillering varieties slightly wider spacing reduces sheath blight and BPH. Avoid very close, random planting as it causes weak tillers, more disease and pest buildup, and difficult spraying. Use a marker or rope for straight rows, which also helps mechanical weeding. For SRI method, single young seedlings are planted at wider 25 by 25 cm spacing. Match spacing to variety and soil fertility.
Switching to proper row spacing with a rope gave me healthier tillers and easier spraying than random planting.
Straight rows also let me run a cono weeder between them, which cut my weeding cost. Random clump planting made any machine weeding impossible. The rope is worth the extra time at transplanting.
I tried SRI with single seedlings at wider spacing and got strong tillering, but it needs careful water control and weeding. On my heavier plot the normal 20 by 15 was easier to manage.
Do not crowd seedlings hoping for more yield. My thick planted patch got more sheath blight and BPH and actually yielded less than the well spaced part of the same field.
