Seasonal fluctuation of N, P, K, Ca, Mg, and micronutrients foliar levels and preliminary standards for N, in garlic

Rafael Ruiz S.1

a nutritional NP trial with garlic (AIIium sativum L.), an association between applied N,yield and leaf N levels was found, through the different stages of development. Over 5.5% of N content in )eaves was adequate for the first growth stage, until pre-bulbing. Values below 4.5% would be deficient, for the same period. Data, on estimated adequate leaf levels for P, K, Ca, Mg, Mn, Zn and Cu, in different periods, are presented.
