Other claims from this paper (13)
- Intervention effect Zinc fertilization improved chlorophyll and Zn concentrations of nursery seedlings.
- Intervention effect Zinc fertilization improved root length and number of roots of nursery seedlings, highest in CF.
- Intervention effect Zn addition gave maximum plant height and panicle length in AWD and CF rice systems.
- Intervention effect Zn addition gave maximum total and panicle bearing tillers in AWD and CF rice systems.
- Intervention effect Zn addition gave maximum kernel yield in AWD and CF rice systems.
- Intervention effect Zn fertilization increased Zn concentration in leaves, culms and panicles under CF and AR at maturity.
- Intervention effect Zn fertilization increased Zn concentration in grains under CF and AR at maturity.
- Observation Most of the applied Zn was allocated into culms and panicles of rice.
- Intervention effect Zn application significantly increased grain Zn concentration in all production systems.
- Intervention effect Zn application after nursery transplanting is more important for grain Zn enrichment than for grain yield increase in rice.
- Intervention effect Zn application after nursery transplanting increased grain yield in AWD.
- Association Rice grain yield was higher under CF and AWD than under SRI and AR.
- Mechanism Higher grain yield under CF and AWD is attributed to decreased spikelet sterility and better Zn phyto-availability.
