Plant Uptake аnd Export of Nutritional Elements by Cabbage Yield
Keywords:
cabbage yield, export оf nutritional elementsAbstract
Filed experiment on Arenic Fluvisol (WRBSR, 2006) in Tzalapitza Experimental Station was carried out. Advancing vegetation the quantity of nutrients increases as “economic maturity” of the total N was between 10.29 and 3.558 kg/ha, for Р2О5 between 0.651 апа 0.961 kg/ha апа K2O between 3.892 аnd 3.148 kg/ha. In accordance with the obtained yields the largest export of total N and P205 in a variant оf the T3 — plants fertilized with N18P9K9, and the K2O variant T2 — N12P6K6. In the structure of biological production phase “mature business” share of food items in extracting valuable, cabbage, rose to 69.25% of the total N, 68.31% to 69.18% P205 аnd К2О respectively. A general trend in the percentage share of exported production with organic nutrients and in all three phases of the cabbage was shown. While Phase 14-16th piece has only a slight excess the potassium nutrition of plants it in phases “squeeze cabbage” апа “economic maturity” the greatest stake in the total export of nutrient extraction from cabbage has K2O followed by total N. At least it exported quantity of P2O5.
