Tomato cultivation in Turkey plays an important economic role and it constitutes almost 40% of the total vegetable production (Aksoy and Kaymak, 2016; Guvenc, 2019). Global tomato production is currently 130 million tons.
There are three cases of irrigation, which can be classified as
Water use efficiency (WUE) is a key issue in arid and semi-arid areas of the world, where water is an increasingly limited source. Water management during the past half-century has been intensified to increase water use efficiency (Medrano et al., 2015; Hatfield and Dold, 2019). The efficiency of water usage is closely related to the method applied. Drip irrigation, which has been used for nearly 50 years, can be accepted as the most efficient method to provide soil moisture in the root zone. It not only controls the usage of the water but also provides efficient use of nutrients and pesticides (Shock, 2006). The Class A evaporation pan is one of the universally used and easy-to-control methods for monitoring soil moisture in terms of water management. The results of various studies have shown that the low level of error in estimates makes Class A pan a favorable tool for the establishing of water consumption and irrigation scheduling for many plants (Ayas, 2015; Senyigit and Arslan, 2018). Numerous surveys have been conducted to assign the pan (kp) and crop coefficients (kc) of tomato in the drip irrigation method (Smajstrla and Locascio, 1990; Locascio and Smajstrla, 1996; Kırnak and Kaya, 2004; Harmanto et al., 2005; Ertek, 2011). Results on the coarse-textured soils showed that the water requirement of tomato varied between 0.5 – 1.0 times of pan evaporation (Locascio and Smajstrla, 1989; Locascio et al., 1989). Results on finer-textured soils showed almost similar water requirements as 0.75 of pan evaporation for spring crop (Locascio et al., 1989) and 0.50 of pan evaporation for fall crops (Olson and Rhoads, 1992). Sustainable agriculture along with proper usage of water supplies
This study was undertaken to assess the yield, IWUE, some quality parameters and energy requirements of drip-irrigated tomato using Class A evaporation data.
