تأثير مستويات المستخلص البحري العضوي Algaton والسماد الكيمياوي NPK في نمو وحاصل القرنابيط Brassica oleracea var.botrytis) )

Abstract

The field experiment was carried out at the site of the Agricultural Research Station of the College of Agriculture - University of Kirkuk during the agricultural of winter season 2018 to influence the effect of organic extract Algaton and Chemical Fertilizers NPK on Growth and yield the cauliflower ( Brassica oleracea var.botrytis) . The organic extract of Algaton and the highly potassium compound fertilizer N P K (10,10,40 ) were used . The Factoril Exprimation was carried out according to the design of complete random sections (R.C.B.D) in three replicates with the first three concentrations of the Algaton organic extract and the second three concentrations of NPK (10,10,40) . The differences between the Duncan multivariate averages were tested at a probability level of 0.05. The results showed that the organic marine extract Algaton . The results showed that the organic marine extract Algaton significantly higher in the most vegetative and cauliflower traits (plant height, number of leaves, stem diameter, number of days until maturity of syphilis, syphilis disk weight, total yield, cohesion and disc color) and at 2 ml (57.69 cm,20.58 leaves/plant,3.79 cm, 133.20 days / plant, 2.00 kg, 5.15 ton / dunam and 3.68°, 3.83 °), respectively, compared with the recorded comparison coefficients (without fertilization) Which was the lowest reading.
