Effect Of Genotype And Spraying Leaves With Arginine And Yeast In Some 1 - Vegetative Growth Characteristics Of Potatoes (Solanum tuberosum L.)

Abstract

Field experiment was conducted in Hibhib area in Diyala province during the growing season in 2015 to study the six transactions of Foliar arginine acid and yeast (arginine acid concentration of 200 Melgm ltr-1 and arginine acid concentration of 300 Melgm ltr-1, yeast concentration of 5 Gm ltr-1, a mixture of arginine acid concentration of 200 Melg ltr -1 and yeast solution concentration of 5 g Ltr-1 (1:1 ratio) and a mixture of arginine acid concentration of 300 Melgm ltr- 1 and 5 Gm ltr-1 yeast solution and by (1:1 ratio) and the treatment control (water drop) on three genotypes of potatoes which (Emma and Rivira and Loane). The experiment carried out in accordance with the system of panels splinter split plot where he developed genotypes in key cutting and spraying transactions in the secondary pieces using design RCBD and three replications, tested moral differences between the averages, according to Duncan test and the level of probability of 0.05. Study proved superiority of installation plants Loena sprayed with a mixture of yeast and arginine acid concentration of 300 Melgm ltr-1 best along for the plant amounted to 66.66 cm, while installation plants recorded Emma sprayed with yeast highest number of aerodynamic shins totaled 6.00 stem plant2, as well as excelled installation plants Emma sprayed with a mixture of yeast arginine acid 300 Melgmaze ltr-1 highest number of securities amounted to 112.00 and leaf, while genotype Rivira plants sprayed recorded Ppalarjnin concentration of 200 Melgm ltr-1 more space and leaf totaled 1920.3 ds2, texturing plants as well as recorded Loena sprayed with a mixture of yeast histidine and arginine 300 Melgm ltr-1 highest percentage of chlorophyll in securities amounted to 51.70 Spade.
