Effect of combinations of fertilizer of macro and micronutrients on nutrients content of garlic cloves Allium sativum L.

Abstract

A field experiment was conducted in Silt loam soil at Al-bu-farraj Northern Ramadi (110 km west of Baghdad) to study the effect of fertilization with different levels of macro- and micronutrients on garlic cloves content (Allium sativum L.) of some nutrients, using randomized complete block design( RCBD) with three replicates for treatment. Four fertilizer formulations from nitrogen, phosphorus and potassium; i.e. A0: 0, 0, 0, A1: 80, 80, 80, A2: 120, 120, 120 and A3: 160, 160, 160 kg.ha-1 were applied and four concentrations of the nutrient solution microm 0, 0.5, 1, 1.5 gm. L-1 were sprayed results showed significant differences among garlic cloves content of nitrogen, phosphorus and potassium 33.86, 2.578, 32.79 gm. kg-1, iron, zinc, copper, manganese 19.49, 27.00, 18.00, 44.090 mg. kg-1 comparing with control. The increases were significant (0.05) with addition levels of the single treatment and interactions for all studied elements with the exception of copper, in which the interactions was non-significant.
