“…The effect of the water and fertilizer coupling treatments on the yield of cabbage in spring was not significant, but it had a significant effect on the yield of cabbage in autumn. Gao et al [35] also drew similar conclusions in a study of Chinese cabbage in Northeast China. The different water and fertilizer treatments in the first season had no significant effect on the yield, but the different water and fertilizer treatments in the second season did have a significant effect.…”

“…Different treatments had significant effects on the head biomass; specifically, the head biomass of spring cabbage in H W L F was significantly higher than that in M W M F and L W H F , and the head biomasses of autumn cabbage in H W L F and M W M F were significantly higher than that in L W H F . Gao et al [35] found that both irrigation and fertilization had significant effects on the root, leaf and total biomass of Chinese cabbage, but the effects of the different water and fertilizer treatments on root, leaf and total biomass were not significant. Erdem et al [18] found that irrigation and fertilization had no significant effect on the head biomass of broccoli but had a significant effect on the biomass of leaves.…”

Understanding the response of crop growth to water and fertilizer is helpful to improve their management and use efficiency. Three water and fertilizer coupling treatments were designed to carry out a two-season trial on two cabbage (Brassica oleracea L. var. capitata) cultivars in spring and autumn in the Beijing–Tianjin–Hebei region. The irrigation timings of the three treatments were controlled by the soil moisture content of 0–20 cm soil layer. Treatment 1 (LWHF): when the soil moisture content was decreased to 75% of the field capacity (θf), irrigation was carried out (i.e., the lower limit of irrigation was 75%θf), the critical soil moisture content for stopping irrigation was 90%θf (upper limit of irrigation), and the nitrogen (N) application amount was 400 kg/ha; treatment 2 (HWLF): the lower and upper limits of irrigation were 85%θf and 100%θf, respectively, and the N application amount was 200 kg/ha; and treatment 3 (MWMF): the lower and upper limits of irrigation were 75%θf and 100%θf, respectively, and the N application amount was 300 kg/ha. The results showed that the yield and its related parameters of cabbage in spring were higher than those in autumn because of the use of different cultivars and seasons. The growth indices of HWLF and MWMF in the two seasons were larger than that of LWHF, and the yields of HWLF were the highest, 78.37 t/ha (spring) and 64.42 t/ha (autumn), respectively. The nitrogen use efficiencies (NUEs) of LWHF in spring and HWLF in autumn were the highest, 213.29 kg/kg and 391.83 kg/kg, respectively. In general, there were statistically significant differences in the cumulative increment in plant height, stem diameter and leaf area in the two-season trial, yield in autumn and NUE in spring among the three treatments. In addition, there was a significant positive linear correlation between almost all indices in different growth stages and the corresponding evapotranspiration (ETi). It is suggested that the application of drip irrigation under mulch should be approximately 114.7–125.0 mm, and the N fertilization should be about 200 kg/ha.

“…The daily nutrient uptake of spring maize can be influenced by crop growth condition, soil compaction, soil water content, and fertilization [35][36][37][38][39]. As the original WOFOST model calculates the seasonal nutrient supply, variation is ignored, which is unproblematic for the nutrient-limited yield estimation at the end of the growth season.…”

Abstract:The approach of using multispectral remote sensing (RS) to estimate soil available nutrients (SANs) has been recently developed and shows promising results. This method overcomes the limitations of commonly used methods by building a statistical model that connects RS-based crop growth and nutrient content. However, the stability and accuracy of this model require improvement. In this article, we replaced the statistical model by integrating the World Food Studies (WOFOST) model and time series of remote sensing (T-RS) observations to ensure stability and accuracy. Time series of HJ-1 A/B data was assimilated into the WOFOST model to extrapolate crop growth simulations from a single point to a large area using a specific assimilation method. Because nutrient-limited growth within the growing season is required and the SAN parameters can only be used at the end of the growing season in the original model, the WOFOST model was modified. Notably, the calculation order was changed, and new soil nutrient uptake algorithms were implemented in the model for nutrient-limited growth estimation. Finally, experiments were conducted in the spring maize plots of Hongxing Farm to analyze the effects of nutrient stress on crop growth and the SAN simulation accuracy. The results confirm the differences in crop growth status caused by a lack of soil nutrients. The new approach can take advantage of these differences to provide better SAN estimates. In general, the new approach can overcome the limitations of existing methods and simulate the SAN status with reliable accuracy.

“…The yield of T3F1 was the highest in all treatments, which was 31.72% higher than CK treatment, and 10.97% higher than CF treatment. As for the multiple topdressing protocol, the soil N availability maintains at reasonable abundant levels in later stages, in which greatest amount of N is required by plants [30][31][32]. This is more advantageous than basal N application alone, in which N is very susceptible to loss [33].…”

A good understanding of the relationship between vegetable quality and soil N balance is very important for proper nitrogen (N) management for crop productions. In this study, a field experiment was carried out to investigate the N application rate and times on Chinese cabbage yield and quality, N use efficiency, soil nitrate-N concentration, and soil pH. The experiment was implemented in a two-way factorial design and the two factors comprises of number of N applications (once, twice and three times, denoted as T1, T2 and T3) and N rates (15%, 30% and 45% less than conventional rates (CF), denoted as F1, F2 and F3, respectively). The treatments were also compared with a no-fertilizer blank and a control (CF) with a conventional N management practice. The results showed that the highest yield of cabbage (164.65 t hm −2), Vitamine C content (14.80 g 100 g −1 fresh mass), soluble sugar content (2.33 mg kg −1), plant N uptake (119.2 kg hm −2) were obtained under T3F1 treatment. Compared with CF treatment, T3F1 treatment significantly increased vegetable yield, vitamin C and soluble sugar content in fruit, and nitrogen use efficiency by 10.97%, 13.76% and 17.68%, and 18.76%, respectively. Nitrate-N content in cabbage was reduced by 7.55% in T3F1 treatment. With the reduced N application rate, soil pH gradually changed from 6.25 to 7.26. T3F1 treatment is a most suitable N management practice for vegetable production, in terms of higher vegetable yield and quality, soil N content, depressed soil acidification and nutrient uptake by Chinese cabbage.
