Other claims from this paper (14)
- Association Hybrid Dhani gold produced higher winter rice grain yield than inbred BRRI dhan29.
- Intervention effect Application of 20 kg N ha-1 at 3.0 LCC value gave the highest winter rice grain yield.
- Intervention effect The SPAD approach with 20 kg N ha-1 at 35 SPAD value gave the lowest winter rice grain yield.
- Intervention effect BRRI dhan29 with 20 kg N ha-1 at 3.0 LCC value gave the highest winter rice grain yield in the interaction analysis.
- Intervention effect BRRI dhan29 with 20 kg N ha-1 at 3.0 LCC value gave the maximum winter rice gross income.
- Intervention effect BRRI dhan29 with 20 kg N ha-1 at 3.0 LCC value gave the maximum winter rice net benefit.
- Intervention effect Dhani gold with 30 kg N ha-1 at 3.0 LCC value gave grain yield statistically identical to BRRI dhan29 with 20 kg N ha-1 at 3.0 LCC value.
- Intervention effect Dhani gold with 30 kg N ha-1 at 3.0 LCC value required 42 kg extra N ha-1 over control.
- Intervention effect Dhanigold with 30 kg N ha-1 at 35 SPAD value gave the lowest winter rice grain yield.
- Intervention effect The 20 kg N ha-1 at 35 SPAD value treatment gave higher gross income than the control.
- Intervention effect The 20 kg N ha-1 at 35 SPAD value treatment gave higher net income than the control.
- Intervention effect The 20 kg N ha-1 at 35 SPAD value treatment gave moderate winter rice grain yield.
- Recommendation The 20 kg N ha-1 at 3.0 LCC value is a promising winter rice practice for inbred BRRI dhan29 in yield, N use efficiency and economic benefit.
- Recommendation The 30 kg N ha-1 at 35 SPAD value is a promising winter rice practice for hybrid Dhanigold in yield, N use efficiency and economic benefit.
