- Intervention effect N, P and K treatments significantly influenced grain yield, shoot dry weight and plant height.
- Intervention effect N, P and K treatments significantly influenced root dry weight, maximum root length and panicle number.
- Intervention effect N, P and K treatments significantly influenced 1000-grain weight and grain harvest index.
- Intervention effect Without P fertilization, rice produced no panicles or grain.
- Observation P was the most yield-limiting of the three nutrients.
- Intervention effect Rice produced no grain under N0P0K0.
- Intervention effect The N300P200K200 treatment gave maximum grain yield.
- Association Grain yield had positive associations with plant height, shoot dry weight and root dry weight.
- Association Grain yield had positive associations with maximum root length, 1000-grain weight and panicle number.
- Association Grain yield had a significant positive association with grain harvest index.
- Association Shoot dry weight had the highest positive association with grain yield among components.
- Recommendation The authors recommend adequate soil and crop management to improve rice growth, yield components and grain yield.
