The pruning treatments included manual spur (MAN) and mechanical hedge (MEC) type of pruning and types of organic amendments applied were biochar (BIOC), municipal solid waste compost (RSUC), cattle manure (ESTR), sewage sludge (ETAR) and control treatment (TEST). The treatment effects were analyzed for chemical composition, mineral content and heavy metals content and sensorial analysis of wine samples. The analysis results show that there was no significant effect of type of pruning on wine composition except pH, total acidity, alcohol content, calcium and total nitrogen content of wine sample. Similar trend was also followed with the application of organic amendments; the composition of wine remained unchanged by the use of organic amendments except some effect on pH, total acidity, volatile acidity, total anthocyanins and potassium content of wine samples. There was no significant increase in the heavy metals content of wine samples after the treatment of organic amendment. The manual pruning generally showed higher content compared to mechanical pruning due to less number of bunches retained per shoots. Wine composition was more influenced by the site specific characters and climatic conditions than the effect of treatment applied. Sensory analysis along with chemical analysis shows that mechanical pruning can be used without having much significant effect on grape composition when sufficient yield compensation is achieved. Treatment which supplied higher amount of nitrogen (ETAR and ESTR) was generally marked by more negative sensory perception such as vegetal characters in wine. On the face of climate change and increased competitive pressure use of mechanical pruning can be good strategy to reduce the cost of grape production and organic amendment can be applied to soil with an aim of increasing organic matter contents of soil. But the care should be taken to avoid excessive supply of nitrogen in order to avoid negative effect on wine composition over longer period of time. So the supply of amendment should be managed according to vine and soil nutritional statusISA/ULSilva, Jorge Manuel RicardoRepositório da Universidade de LisboaKhairnar, Kaushal2017-12-31T01:30:10Z20142014-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.5/8632engKhairnar, K. - Effect of different organic amendments on soil quality, vines growth, grape production and wine quality of mechanically pruned vineyards.
