Abstract
This study was conducted at the field of the Department of Horticulture – College of Agriculture – University of Baghdad – Abu Ghraib, during 2010 and 2011 seasons. That was to study the effect of nitrogen fertilization and foliar application of nutrient solution (TOTALGRO) containing NPK on growth and leaf mineral content on local kohlrabi cultivar. The experiment included 16 treatments wich were the interactions between four levels of nitrogen fertilization, [(N0), 60 kg N/ha ( N1) , 120 kg N/ ha( N2) and 160 kg N/ ha( N3) ] and four concentrations of nutrient solution spray (T1), (20-20-20) (T2), (10-52-10) (T3) and (12-12-36) (T4). Each treatment replicated three times with a factorial experiment using RCBD. The experimental results showed that interaction of nitrogen fertilization and nutrient solution spraying (N3T4) was significant it gave the highest leaf number (20,36 and 21,24 leaf per plant) and the highest leaves content of nitrogen (1,59% and 1,50 %) and the highest leaves content of Potassium (1,290% and 1,313%) and the bulbous stems mean weight (423,6 and 445,6 g/plant) for both seasons, respectively. The lowest value of these parameters were found in the control (N0T1) treatment. We recommended conducting these treatments annually and to study the effect of another levels of nitrogen and nutrient solution along with higher population densities.
