Mineral composition and growth responses of tomato (Solanum lycopersicum L.) plants to irrigation with produced waters from the oil industry

Abstract

ABSTRACTProduced waters are considered a byproduct from the oil industry that may contain mineral elements essential for plant nutrition, which enables them for irrigation purposes. Due to the growing demand for water for agricultural use in the world, the aim of this study was to determine the feasibility of using dilutions of fresh water and produced water derived from the gas-producing zone of Sabinas-Piedras Negras, in northern México and their effect on mineral content and allocation, growth, and yield of tomato plants. The results showed that the dilutions containing produced water reduced fruit, stem, and leaf fresh weight, and that the uptake and accumulation of minerals in plant tissues, except for sodium, was also decreased. However, plants irrigated with dilutions of produced and fresh water showed increased translocation of essential minerals from the leaves to the fruit, which partially contributed to alleviate the negative effects on fruit yield.
