Exploring the interactive effect of water and fertilizer on yield, soil water and nitrate dynamics of young apple tree is of great importance to improve the management of irrigation and fertilization in the apple-growing region of semiarid northwest China. A two-year pot experiment was conducted in a mobile rainproof shelter of the water-saving irrigation experimental station in Northwest A&F University, and the investigation evaluated the response of soil water and fertilizer migration, crop water productivity (CWP), irrigation water use efficiency (IWUE), partial factor productivity (PFP) of young apple tree to different water and fertilizer regimes (four levels of soil water: 75%–85%, 65%–75%, 55%–65% and 45%–55% of field capacity, designated W1, W2, W3 and W4, respectively; three levels of N-P2O5-K2O fertilizer, 30-30-10, 20-20-10 and 10-10-10 g plant−1, designated F1, F2 and F3, respectively). Results showed that F1W1, F2W1 and F3W1 had the highest average soil water content at 0~90 cm compared with the other treatments. When fertilizer level was fixed, the average soil water content was gradually increased with increasing irrigation amount. For W1, W2, W3 and W4, high levels of water content were mainly distributed at 50~80 cm, 40~70 cm, 30~50 cm and 10~30 cm, respectively. There was no significant difference in soil water content at all fertilizer treatments. However, F1 and F2 significantly increased soil nitrate-N content by 146.3%~246.4% and 75.3%~151.5% compared with F3. The highest yield appeared at F1W1 treatment, but there was little difference between F1W1 and F2W2 treatment. F2W2 treatment decreased yield by 7.5%, but increased IWUE by 11.2% compared with F1W1 treatment. Meanwhile, the highest CWP appeared at F2W2 treatment in the two years. Thus, F2W2 treatment (soil moisture was controlled in 65–75% of field capacity, N-P2O5-K2O were controlled at 20-20-10 g·tree−1) reached the best water and fertilizer coupling mode and it was the optimum combinations of water and fertilizer saving.

“…Pérez-Sarmiento et al [138] applying several RDI strategies to apricot have found improvements in some qualitative characteristics of the fruits, such as the level of soluble solids, sugar/ acid ratio, and fruit color, without negative effects in yield. Along with these characteristics, fruit firmness was also improved in a study conducted by Zhou et al [135] when applying an SDI strategy with a light water stress. Therefore, from these studies, it can be concluded that the use of deficit irrigation in peach doesnot seem to induce negative effects in the fruit quality parameters referred above.…”

In regions with Mediterranean climate, water is the major environmental resource that limits growth and production of plants, experiencing a long period of water scarcity during summer. Despite the fact that most plants developed morphological, anatomical, physiological, and biochemical mechanisms that allow to cope with such environments, these harsh summer conditions reduce growth, yield, and fruit quality. Irrigation is implemented to overcome such effects. Conditions of mild water deficit imposed by deficit irrigation strategies, with minimal effects on yield, are particularly suitable for such regions. Efficient irrigation strategies and scheduling techniques require the quantification of crop water requirements but also the identification of pertinent water stress indicators and their threshold. This chapter reviews the scientific information about deficit irrigation recommendations and thresholds concerning water stress indicators on peach trees, olive trees, and grapevines, as case studies.

“…Conesa et al [12] found that deficit irrigation at harvest would improve fruit quality of watermelon, hot pepper and tomato due to increased total soluble solids and juice proline content. Furthermore, the deficit irrigation can significantly reduce the titratable acid content of peach fruit [13] , and increased irrigation can significantly reduce the VC, lycopene and SS content of tomato [14] . Previous research has focused on the effects of water stress on tomatoes [15,16] , but no studies have been conducted on the effects of water stress on different tomato bunches.…”

The aim of this study was to investigate the effects of tomato quality and yield between different bunches and the differences between the two comprehensive evaluation methods on tomato quality ranking under water stress. Two degrees of water stress including mild water stress (W1) and moderate water stress (W2), and three growth stages that water stress applied including seedling stage (S1), flowering stage (S2) and fruit expanding stage (S3) were tested in this study. The yield and quality of different bunches of tomatoes under water stress during different growth stages were determined as responses, and the comprehensive fruit quality ranking and yield of the second and third bunches were evaluated. The results showed that water stress was important for the improvement of fruit quality, but fruit yield decreased during water stress. The yield of the third tomato bunch decreased from 11.69% (W1S1) to 30.60% (W2S2) compared to control (97.57 t/hm 2), and the effects of mild water stress on fruit yield were minimal at the early growth stage. However, the fruit quality in terms of soluble sugar (SS), total soluble solids (TSS), vitamin C (VC), and firmness (F) improved under water stress compared to control. The combined effects of water stress and its application period significantly affected SS and TSS. Water stress significantly improved the content of SS and TSS in the later growth period compared to seedling and flowering stages. Meanwhile, there was a significant difference in tomato quality between the second and third bunches of fruit, especially in the content of SS, organic acid (OA) and lycopene (L). Principal Component Analysis (PCA) and Grey Relational Analysis (GRA) were used to evaluate comprehensive fruit quality, and the best treatment in terms of the fruit quality was W1S3 for both bunches. The rank-sum ratio (RSR) method was used to evaluate fruit quality and yield, the results showed that W1S3 ranked first based on PCA and W1S1 ranked first based on GRA. Water stress enhanced tomato quality but inevitably reduced its yield during each growth stage. The application of mild water stress during the fruit expanding stage (W1S3) was considered to be the best treatment to provide satisfactory fruit quality and yield based on RSR.
