Implication

Field study reveals zinc fertilizer improves growth and yield metrics in rice, indicating optimal application rates are crucial.

Key Points

  • The research aims to evaluate the effect of varying zinc fertilizer levels on rice growth and yield parameters.
  • Field study conducted with rice varieties: Super Basmati and KSK 434.
  • Various levels of zinc fertilizer applied (0.0, 5.0, 7.5, 10.0, 12.5, and 15 kg Zn ha-1).
  • Growth metrics measured included plant height, tillers per meter squared, and spikelets per panicle.
  • 15 kg Zn ha-1 application increased plant height by 15.2% in Super Basmati.
  • Zn application improved the number of tillers by 4.42% (Super Basmati) and 2.75% (KSK 434).
  • Spikelets per panicle increased by 82.5% (Super Basmati) and 37.9% (KSK 434) with 15 kg Zn ha-1.
