IMPACT SAFE NUTRIENTS IN RAISING PRODUCTION AND CHMICAL CONTENTS OF POTATO

This study was amied to evaluating the efficiency of foliar fertilization with organic cobalt and environmentally friendly nutrients in improving production chemical content potatoes at experimental fields College Agricultural Engineering Sciences/ University Baghdad.A factorial experiment (3×7) applied using a Randomized Complete Block Design three replications, first factor ATP SMART as an source concentrations (0, 1, 2 ml L-1), second includes aqueous solution powdered cow's milk two (10 20gL-1),and bio stimulants STIMPLEX (5 10 L-1) dry yeast 15 gL-1) well control t.The results were revealed that spraying (1 able record highest values leaves area (52.06 47.68 dcm2 plant-1) inboth seasons respectively, treatment (2 recorded weight vegetative growth (41.34 39.05gplant-1) respectively for both seasons.The showed significant superiority by recording market rate tuber matter starch season.The (20 g L-1)recorded under conditions spring season (57.13 plant-1), superior (51.49 fall (10gL-1yeastand 20gL-1milk) gave number marketable tubers seasons.
