Seasonal average fractional interception of photosynthetic active radiation (FIPAR, %) values for the different treatments and the average for treatments groupings. For statistical
significance, see footnote *.
Peak tiller population (tillers m−2) for the different treatments and the average for treatments groupings. Final stalk population is shown in brackets. For statistical significance,
see footnote *.
* Peak tiller population: Season, row spacing, surface cover and variety effects were highly significant (P
≤
0.01) with least significant difference (LSD) values of 1.8,1.3, 1.3 and 1.3 tillers m−2, respectively. Final stalk population: Season, row spacing and variety effects were highly significant (P ≤0.01) with LSD values of 0.6, 0.4 and 0.4 stalks m−2, respectively.
