During 1983/84, a field experiment was carried out at La Platina Research Station (INIA, Santiago). Treatments were 11 water application rates, using the method proposed by Hanks et al (1976): the simple line sprinkler system. Results indicated that the roots of the crop were mainly in the first 60 cm of soil. This knowledge, in conjunction with the crop coefficients presented in Part 1, give the necessary elements to develop irrigation programmes for th is species. Also, it was found that the variations in the percentage of N and K were minor with respect of crop yield. Resu Its obtained, make it possible to manage both irrigation and fertilization practices, according to climate and soil conditions and expected crop yield.
