Evaluation of yield and water productivity of greenhouse strawberry under different irrigation regimes in soil and non-soil media

In order to investigate the effect of cultivation medium on yield, water productivity and some growth characteristics of strawberry plant, an experiment was carried out in the greenhouse as a factorial based on a completely randomized design with two factors of cultivation medium and irrigation levels. Irrigation treatments at three levels included full irrigation (FI), deficit irrigation at 80 (DI80) and 60% of water requirement (DI60) and four cultivation media including soil (Soil), cocopeat : perlite with volume ratios of 30:70 (C30 P70), 40:60 (C40 P60) and 50:50% (C50 P50). The results showed that the highest values of fruit yield and water productivity among cultivation medium treatments were allocated to C50 P50 treatment with 8.99 kg / m2 and 41.53 kg / m3, respectively, and among irrigation treatments were belonged to FI treatment with 9.53 kg / m2 and 35.88 kg / m3 respectively. The highest values of yield and water productivity in the interaction of the studied factors were 11.41 kg / m2 in C50 P50 composition with full irrigation treatments and 44.78 kg / m3 in C50 P50 composition with 80% water requirement treatments. Based on the results of this study, in case of deficit irrigation application, C50 P50 medium with deficit application of 80% water requirement can be suggested.
