  3. 3. <ul><li>Winkler, A.J. (1962). General Viticulture. California: University of California.</li></li></ul><li>The nitrogen uptake cycle<br />Spring: High uptake of nitrogen due to growth season as nitrogen is used as a base backbone for DNA, protein, amino acid, and other component building block for producing new tissue (cell division & cell elongation)<br />Summer: Low-medium uptake, nitrogen uptake during this season is depended upon the growth cycle of the plant. <br /><ul><li>Coombe, B.G., & Dry, P.R. (2006). Viticulture: volume 2 practises. South Australia: Winetitles </li></li></ul><li>The nitrogen uptake cycle<br />Autumn: nitrogen uptake slows down, leaves become brown and die as the nitrogen is pulled back from the green tissue to the roots for storage.<br />Winter: no nitrogen uptake, nitrogen is fully stored in the roots for the next growing season, wood is lignified & leaves completely fall off. <br />Bear in mind that we look at this aspect as the seasonal perspective although nitrogen uptake on vine actually depended upon the grapevine growth cycle<br /><ul><li>Coombe, B.G., & Dry, P.R.

  6. 6. Effect of nitrogen fertigation on Reproductive growth<br />High berry number per bunch  High yield<br />Minimize inflorescence necrosis<br />Nitrate acts as a inhibitor for formation of total phenol and anthocyanin by sucrose.<br />
  7. 7. <ul><li>Fertigation, Retrived http://www.pacificag.co.nz/pages/54/fertigation.htm</li></li></ul><li>Excessive nitrogen supply<br />Vine can become imbalance (high vigour leads to more vegetative growth).<br />Shading causing high disease pressure.<br />Toxic due to deposition of white amino acid salts causing severe burning in the leaves.<br />High juice to skin ratio not suitable for red wine production<br />Causing bunch stem necrosis<br />
  8. 8. Sunburn!!<br /><ul><li>Winery & Vineyard, http://www.practicalwinery.com/SeptOct05/septoct05p24.htm</li></li></ul><li><ul><li>Winery & Vineyard, http://www.practicalwinery.com/SeptOct05/septoct05p24.htm</li></li></ul><li>Deficit of nitrogen supply<br />Low vegetative growth (vegetative growth is needed prior budburst onwards until veraison)<br />Less photosythesis rate reaction in the plant<br />Low in chlorophyll content<br />Can lead to abortion of entire inflorescence<br />If accompanied by good light exposure produce anthocyanin profile that is dominant in Dp-3-glucoside.<br />
  9. 9. Conclusion<br />The application of nitrogen need to be consider according to weather pattern, type of soil, irrigation, rootstock used, environmental issue, etc<br />As the impact with vine balance also need to be consider since excessive and deficit of nitrogen will effected the reproductive and vegetative growth<br />Vegetative vigour can be regulate by strategising the supply of Nitrogen to the vine.<br />Fertigation is an important tool in application of Nutrients to the vineyard.<br />
