| Abstract | ||
| This research was conducted during the spring season of 2013, at the Project of tomato and potato development / Department of plant production /directorate of Nineveh agricultural ,Iraq .The aim of this study was to investigate the effect of foliar spray of Seaweed extract (LAY- O = 3 ml / L ), High P ( Soliveg T B 10 = 3 gr /L ) and Organic nitrogen ( Essential = 6 ml / L ) on two potato varieties ( DRAGA and TAURUS ) . Randomized Complete Block Design (RCBD) with three replicate for each variety was applied in this research .All data were tested by using Duncan’s multiple range tested under 0,05. Results obtained that DRAGA variety significantly increase in average of leaf area , no. of stem/ plant , average of tuber weight ,yield / plant , yield / unit area as compared with Taurus variety. Some bi-interaction treatments between varieties and material resulted in a significant increase in some vegetative growth, yield and quality parameters. | ||
