EFFECT OF INCREASING NITROGEN DOSES ON YIELD AND QUALITY OF SPINACH
In two years on the experimental field of the Institute of Field and Vegetable Crops, the Faculty of Agriculture in Novi Sad/Yugoslavia/, on the chernozem soil, the effect of increasing doses of nitrogen/from 0 to 200 kg/ha/ on yield and quality of spinach varieties: Dark Green Bloomsdale and Matador were studied. We also determined the nitrate and nitrite content. Spinach yield increased with increasing nitrogen doses of 150 kg/ha. The nitrate and nitrate content did not significantly change when nitrogen doses were increased to 200 kg/ha.
