Phosphorus Fertigation and Preplant Conventional Soil Application of Drip Irrigated Grapevines
Year: 2016
Type: article
Abstract: IELD experiment was conducted for two consecutive ………seasons (2011 and 2012) to compare Grapevine response to conventional soil P application as triple super phosphate (TSP) and fertigation when P is applied in the form of phosphoric acid (H 3 PO 4 ), ammonium polyphosphate (APP) and urea phosphate (UP).Two rates of phosphorus were used, 20 and 40 Kg P 2 O 5 /fed.Plant and soil samples were collected and analyzed for chemical analysis.The data presented that total soluble solid (T.S.S), leaf petioles P, Zn, Fe, yield and P concentration in soil were higher with P fertigation than conventional soil P application and increased with increasing P rate.While the soil pH decreased significantly under P fertigation compared to conventional soil application.As a source of P fertigation, the obtained revealed data presented that APP gave the highest T.S.S, leaf petioles P, Zn, Fe, yield and P concentration in soil compared with H 3 PO 4 and UP.While UP gave the lower value of soil pH.
