The Effect of Different Sources of Calcium on the Some of Quantitative and Qualitative Parameters of Tea Plants (Camellia sinensis L.)

Soil pH is one of the important chemical characteristics of soil that plays major role in growing of tea plant and affects on absorbing of food elements by plant and their usability. In this study، the effect of different calcium source was investigated on some of quantifying parameters in tea plant، pH and EC in tea soil. Tea is plant with shallow roots، this shrubs grows two forms wild and farmed. The leaves of plant are the use in tea that is important economically. This study was conducted as a factorial with two factors، calcium fertilizer type and fertilizer levels on the basis Completely Randomized Design (CRD) with three replications. In order to supervise content of calcium component which contains calcium carbonate، dolomite، calcium oxide and calcium chloride with four levels (0، 1، 2، 3) g ca / kg was added to soil with three replications. The result of analysis of variance related to calcium fertilizer on soil pH indicated that only calcium fertilizer type in soil pH is significant at 0. 1%. Also the result of calcium fertilizer on soil EC showed that the type of calicum fertilizer، fertilizer level and interaction effects and level of fertilizer on soil EC is significant at 0. 1%. But the effect of different sources of calcium has not significantly different on parameters of quantity in tea plant during investigation (three months).
