An RCBD trial is the standard for agronomic trials used to make sure fertilizer treatments are compared under similar circumstances.
If there is known (or suspected) field variability, It is “blocked” in the field to remove any advantage or disadvantage one treatment might have because of its position in the field.
In a RCBD, a set of experimental treatments are grouped (blocked) in a way that minimizes the variability within each block. We then have other blocks and each contains a complete set of treatments. As a result, we reduce variability within one replicate. Meanwhile we will actually increase variability between the replicates in comparison with each other which can be estimated as a separate source of variation.
The removal of this source of within replicate variation reduces experimental error and improves the ability of the experiment to detect smaller treatment differences. The greater the variability among blocks, the more efficient the design becomes.
At Azeems Pvt. Ltd – all our agronomic trials conducted in collaboration with research institutes are done in line with international standarized agronomic good practises. We produce actionable data on developing effective fertiliser plans & further the progress of science in Pakistan’s agriculture sector.
