Intervention effect Direct-seeded rice plants had greater height and tiller production than transplanted rice at all growth stages.
Intervention effect Direct-seeded rice experienced higher tiller mortality later in growth than transplanted rice.
Intervention effect Direct-seeded rice had higher early-stage dry matter accumulation than transplanted rice.
Intervention effect Dry matter accumulation did not differ significantly between direct-seeded and transplanted rice at later stages or at harvest.
Intervention effect The number of effective tillers did not differ significantly between direct-seeded and transplanted rice.
Intervention effect Direct-seeded rice had 16% more grains per panicle than transplanted rice.
Intervention effect Test weight was the same in direct-seeded and transplanted rice.
Intervention effect The transplanted crop had a significantly higher grain yield (11.9%) than the direct-seeded crop.
Intervention effect Increasing nitrogen dosage up to 120 kg N/ha positively influenced growth parameters and yield-contributing characters.
Intervention effect Grain yield was significantly enhanced with increased nitrogen dosage.
Intervention effect Grain yield did not differ significantly between 120 and 150 kg N/ha.
