Title

INVESTIGATION ON EFFECTS OF NITROGEN AND POTASSIUM SPRAY ON QUALITATIVE CHARACTERISTICS AND SOME OF EFFECTIVE PHYSIOLOGICAL FACTORS IN BEARING OF VITIS VINIFERA L. 'SOLTANI'

Abstract

 The nutrient FOLIAR APPLICATION is an effective method for providing the plant different elements and optimum using of manures. In this investigation, 0, 1 and %1.5 urea and 0, 1 and %2 K2SO4 were sprayed on the 18 years-old GRAPEVINEs in a randomized complete block design in Malekan (located in southern part of East Azarbaijan) region. Results indicated that the urea spray affected the berry set percentage, TOTAL SOLUBLE SOLIDS (TSS) and total berry sugar. This study indicated that urea application at early period of growth had great effects on the qualitative characteristics. Application of %1 urea at prebloom stage plus %1.5 urea at post petal abscission significantly increased the amount of total berry sugar. Application of %1 K2SO4 resulted in the highest TSS at the problem + post petal abscission + veraison + post harvest. Stages the amount of leaf SOLUBLE CARBOHYDRATEs was increased through K2SO4 spray in all the treatments compared to the control. In the POTASSIUM treatments, there was a positive correlation between the total leaf protein and the number of clusters per bud in the next year, although this correlation was not significant. The highest number of clusters per bud was produced in the treatments which total protein and SOLUBLE CARBOHYDRATE of leaf were the highest.
