Which of the following agronomic practices is not applicable to rice production?

The agronomic practice that is not applicable to rice production is staking. Staking is a practice of providing support to the stem of some crops like tomatoes, pepper, and beans, among others, to prevent the stems from breaking due to the weight of the fruit. Rice, on the other hand, is not staked because it is not a climbing plant. Threshing is a process of separating the grains from the straw or chaff after harvesting. Transplanting is the practice of uprooting seedlings from the nursery bed and replanting them on a well-prepared field. Puddling is the practice of churning the soil in a waterlogged field to make it muddy and reduce water loss. These practices are commonly used in rice production to achieve high yields.
