“…Among many factors affecting crop growth, water and fertilizer are key factors that can be adjusted and controlled. In actual agricultural production, to obtain higher yields, excessive water use and fertilization have become standard practices, and these practices not only leach nutrients from surface soil to deep soil, reducing water and nutrient use efficiency [1,2], but may also cause soil environmental deterioration [3,4]. To improve the efficiency of water and fertilizer use and determine the appropriate amount of water and fertilizer for crop growth, some authors have studied winter wheat [5], potato [6][7][8], tomato [9,10], broccoli [11,12], onion [13] and areca nut [14], among other crop species.…”

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.

“…Thanks to using slow-release fertilizers, in certain soil and climatic conditions production efficiency can be increased and dispersion of biogens in the environment can be reduced, which has been highlighted by numerous authors (Shan et al, 2015;Li et al, 2017). As a rule, slow-release fertilizers are characterized by a slower release of nutrients, which should allow for their application near the plant root zone.…”

“…Using slow-release fertilizers is a method of fertilization optimization the importance of which has been increasing in the recent years (Gaetano et al, 2016;Nardi et al, 2017;Chen et al, 2018). In these fertilizers, coatings made of various compounds of natural, synthetic or biological origin are a barrier limiting the transfer of fertilizer components to the soil solution (Li et al, 2017). Slow-release fertilizers are used in order to reduce the total amount of plant nutrients introduced into the environment and to limit the energy consumption for fertilization.…”

The aim of this study was to assess the possibility of using slow-release fertilizers under intensive vegetable cultivation. To achieve the set research objective, a field experiment was set up in 2017, where slow-release fertilizer (NPK (%) 20-10-10+4MgO) was applied. The experiment comprised three levels of fertilization with the use of slow-release fertilizers, the control without fertilization, and the control fertilized with conventional fertilizers. The slow-release fertilizer was applied directly under each plant and in rows – approximately 8 cm below the root level. The designed systems were evaluated based on the size of commercial yield, productivity index, agronomic efficiency index, removal efficiency index, and physiological efficiency index. The results obtained in the field experiment indicate that the highest plant yield (54.22 Mg of commercial yield∙ha−1) was obtained at the highest dose of slow-release fertilizers (600 kg∙ha−1 applied in rows approximately 8 cm below the root level). In the case of direct fertilization, in the treatment with the highest dose of slow-release fertilizer, a reduction in yield was observed. The best results, in terms of equalizing the mass of individual roots, were obtained under conventional fertilization. The most favorable value of the productivity index was obtained in the variant where 400 kg∙ha−1 slow-release fertilizer was applied directly, while in the case of row application the best results were obtained at the dose of 600 kg∙ha−1. Celeriac fertilization with slow-release fertilizers under root may result in producing a yield of bigger differences in root mass, compared to conventional fertilization system.

“…The use of slow-release fertilizer (SRF) is characterized by a moderate but consistent nutrient supply over a long period, which improves nutrient-use efficiency, and reduces leaching losses (Li et al 2017). Incorporation of SRF directly into the nursery growing medium has the potential to improve nutrient loading for field growing.…”

Yellowhorn ( Bunge) has been widely planted for biodiesel production in China, but has frequently shown poor field performance. Container-grown yellowhorn seedlings originating from three Chinese provenances, Wengniute Qi (WQ), Alukeerqin Qi (AQ), and Shanxian (SX), were fertilized with slow-release fertilizer (SRF) at 40, 80, 120, 160 or 200 mg N seedling. Tree growth, survival and nutrient content were measured after one yearâs growth in a greenhouse followed by two years in a field site. Plants from AQ and SX tended to have higher stem and root P contents in the nursery. Higher rates of SRF increased root N, and stem and root P contents. After one year in the nursery, there were a number of interactions between provenance and SRF for plant growth responses and nutrient content in the nursery, however after two years of additional growth in the field, plants from the different provenances generally responded similarly to applied SRF in the nursery, with few interactions. Final plant height was approximately 10% lower in trees from provenance SX but was not affected by application of SRF. Conversely, final trunk diameter and stem and root biomass were unaffected by provenance but increased with higher rates of applied SRF. Our results indicate that application of SRF may be a useful tool to nutrient load yellowhorn in the nursery and facilitate transplanting performance in the field. Overall, optimal nursery and field performance of yellowhorn were observed in provenance AQ at 120â200 mg N seedling SRF. We suggest that growers consider a wider range of yellowhorn provenances and SRF rates (above 200 mg N seedling) to yield even better growth response.Xanthoceras sorbifoliumâ1â1â1
