For R 570 aged 44 weeks, they were 131 mm, 27.6, 21.0 and 24.3 °C for samples harvested in 2001 at 113 mm, 28.4, 19.9 and 24.1 °C; and for R 570 aged 36 weeks, they were 145 mm, 28.3, 21.6 and 25.0 °C for samples harvested in 2001 and 131 mm, 28.7, 20.4 and 24.5 °C. The growing conditions of the two crops of R 570 with respect to rainfall, maximum, minimum and mean temperatures are therefore comparable.
The crop of R 570 sampled in 2001 was grown at Mon Trésor (see Fig 1.1) on a Latosolic Reddish Prairie P3 (slightly weathered and shallow) soil, while that sampled in 2003 was grown at Nouvelle Industrie on a Low Humic Latosol L2 soil. Classifications of mineral resources and soil types in Mauritius have been described by Simpson (1951) and Parish and Feillafé (1965).
