Jayeshkumar A. Bhabhor; Kirti Bardhan; Dhiraj P. Patel; et al. International Journal of Current Microbiology and Applied Sciences 2018. doi:10.20546/ijcmas.2018.707.150
Other claims from this paper (15)
- Intervention effect Nitrate and ammonia significantly reduced seminal root length, whereas organic N increased it.
- Association Main root angle increased significantly with increasing N concentration.
- Intervention effect The main root became steeper under N deficiency.
- Intervention effect Main root straightness was unaffected by N availability.
- Intervention effect Nitrogen source significantly affected main root straightness, which was highest under organic N and lowest under ammonium.
- Intervention effect Lateral root number increased with nitrate and ammonia up to 100% relative to organic N.
- Intervention effect Mean lateral root length did not fluctuate among nitrogen forms.
- Intervention effect Summed lateral root length was higher with nitrogen sufficiency.
- Intervention effect Lateral root density was significantly reduced at 0% N.
- Intervention effect Nitrogen sources and levels significantly influenced total root system size.
- Observation Total root system size was the least phenotypically plastic root trait under nitrogen variation.
- Observation Lateral root density was the most phenotypically plastic root trait under nitrogen variation.
- Intervention effect Combined nitrate and ammonia nutrition was judged most suitable for rice root system and seedling growth.
- Recommendation The authors recommend breeding varieties suited to organic agriculture.
- Observation IR-28 may be inefficient for organic nitrogen uptake or assimilation.
