| The normal practice with furrow irrigation in the west of the island is to stop the inflow of water as soon as it has reached the end of the furrow and to bund the latter to allow in situ water percolation. In a trial, surface irrigation was carried out every 10 and 20 days. It was found that, over the whole season, more water was required for the less frequently irrigated treatment because of higher contact time. This resulted in a higher soil moisture availability for the 20-day treatment and higher cane and sugar yields at harvest, even though agronomic data showed little difference in cane development between the two treatments except for one particular case. However, since water is limiting, a larger area may be irrigated with the shorter-interval treatment. A simple calculation showed that the net total yield for the 10-day interval irrigation would be higher than for the 20-day one when the same amount of water is applied. | |
