The Effects of Salt Levels in Irrigation Water With Various Salt Dissolubility on The Yield of Lettuce (Lactuca Sativa)

16322

The aim of this study was to determine the effects of salt levels in irrigation water with different salt dissolubility on the growth and yield of Lettuce (Lactuca Sativa). The research was conducted at 4 different irrigation water salinity level (T1= 0 dS/m, T2= 2 dS/m, T3= 4 dS/m and T4= 6 dS/m) which was prepared by using highly soluble sodium chloride (NaCl) salt and less soluble calcium sulfate (CaSO4) salt. Two separate experiments were designed in completely randomized plots with three replications under greenhouse conditions. Wet (fresh) and dry weights of lettuce were measured. According to results the highest average yield (wet weight) were obtained at T1 (57.96 gr/pot) treatment and followed by T2 (30.07 gr/pot), T3 (21.10 gr/pot) ve T4 (14.39 gr/pot) respectively at high soluble salt NaCl. For low soluble salt CaSO4 average yield were measured as 62.37 gr/pot, 32.55 gr/pot, 28.8 gr/pot and 26.17 gr/pot at T1, T2, T3 and T4 treatments respectively. The same trend was determined in dry weight. As a result; even if the same level of salinity irrigation water containing NaCl was found to be more detrimental to irrigation water containing CaSO4. This also shows that the irrigation water salt types are important as water salinity level.
