A greenhouse experiment was conducted at the Indian Institute of Horticultural Research (IIHR), Bangalore to study the interaction effect between phosphorus and zinc on their availability in soil in relation to their contents in stevia (Stevia rebaudiana). The results show that the amount of available P and Zn content in soil has been found to increase initially and, thereafter, the amount of the same decreased with the progress of plant growth up to 60 days irrespective of treatments. The amount of P and Zn in soils showed an increase with their separate applications either as soil or foliar spray while that of the same value significantly decreased both in soils and plants due to their combined applications, suggesting a mutual antagonistic effect between Zn and P affecting each other's availability in soil and content in the stevia plant.
在班加罗尔的印度园艺研究所（IIHR）进行了一项温室试验，以研究磷和锌之间的交互作用对其在土壤中的有效性以及与甜叶菊（Stevia rebaudiana）中含量的关系。结果表明，无论处理如何，在植物生长至60天的过程中，土壤中有效磷和锌的含量最初有所增加，此后则随着植物生长而减少。单独以土壤或叶面喷施的方式施用磷和锌时，土壤中磷和锌的含量有所增加，而由于二者的联合施用，土壤和植物中的磷和锌含量均显著降低，这表明锌和磷之间存在相互拮抗作用，影响彼此在土壤中的有效性以及在甜叶菊植株中的含量。
