The following data refers to yield of tomatoes (kg/plot) for four different levels of salinity. Salinity level here refers to electrical conductivity (EC), where the chosen levels were EC = 1.6, 3.8, 6.0, and 10.2 nmhos/cm. (Use /= 1, 2, 3, and 4 respectively.) 1.6: 59.1 53.7 56.6 63.5 58.2. 3.8: 55.5 59.1 52.8 54.3 6.0: 51.7 48.8 53.7 48.5 10.2: 44.4 48.5 41.5 47.1 46.1.
