“…Barraclough (1989) reported oilseed rape nutrient uptake amounts of 67·4 kg N, 8·0 kg P and 57·0 kg K/1000 kg seed at a yield of 5·4 t/ha. Orlovius (2003) showed that the nutrient requirements for a seed yield of 3·5 t/ha were 57·4–85·7 kg N, 11·4–16·2 kg P and 83·3–107·1 kg K/1000 kg seed.…”

“…The nutrient requirements of oilseed rape are substantial (200–300 kg nitrogen (N)/ha, 39–57 kg phosphorus (P)/ha and 292–375 kg potassium (K)/ha) and higher than those of cereal crops (Orlovius 2003; Brennan & Bolland 2009). Many studies on the crop nutrient requirements of field and potted oilseed rape have been presented (Barraclough 1989; Taylor et al 1991; Fismes et al 2000; Orlovius 2003; Brennan & Bolland 2009). High variability in the crop nutrient requirements with respect to soil, cultivar, climate conditions, fertilizer inputs, yield level and crop management practices have also been detected (Berry et al .…”

SUMMARYEstimating crop nutrient requirements for winter oilseed rape (Brassica napus L.) is a crucial step in optimizing fertilization to enhance seed yield and improve fertilizer use efficiency. In the present paper, a database composed of 1035 on-farm observations collected from 2005 to 2010 across the major winter oilseed rape production regions in China was used to evaluate internal nutrient efficiencies (kg seed per kg nutrient in plant dry matter); then the Quantitative Evaluation of the Fertility of Tropical Soils (QUEFTS) model for winter oilseed rape was developed to describe the nutrient uptake-yield relationship of oilseed rape over a wide range of environmental conditions and predict the nutrient requirements for a target yield. After excluding observations with low harvest index values, <0·20, and excluding 0·025 of the highest and lowest internal nutrient efficiencies, the minimum and maximum internal nutrient efficiencies were estimated as 13·1 and 31·6 kg seed/kg nitrogen (N), 68·9 and 200·3 kg seed/kg phosphorus (P) and 8·9 and 31·1 kg seed/kg potassium (K), respectively. On the basis of the data settings, the balanced N, P and K uptake at different yield potential levels was calculated using a linear–parabolic–plateau curve with the QUEFTS model. Crop nutrient requirements increased linearly until the yield reached approximately 0·60–0·70 of the potential yield, and 46·0 kg N, 8·0 kg P and 57·1 kg K were found to be needed to produce 1000 kg of seed. The corresponding internal nutrient efficiencies were 21·8, 125·1 and 17·5 kg seed/kg N, P and K, respectively. However, when the target yields approached the yield potential, a decrease in internal nutrient efficiencies was detected in the model. The predicted nutrient requirement values simulated by the QUEFTS model compared well with observed values across a range of conditions. To conclude, the QUEFTS model was shown to be a practical and robust tool for assessing the crop nutrient requirements of winter oilseed rape.

“…Similarly, sulfur regulates inner working of plants and is not as available in aquaponics substrates as in traditional soil (Kristek et al, 1997). Again, the experimental plant "beetroot" is one of the high mineral demanding plants therefore field trials (1998)(1999)(2000) implied that foliar application of epsom salt with the addition of menganese and boron increased yield of sugar beets by 3-5% (Orlovius, 2001). So, it is justified that magnesium and sulfur are to be supplied in aquaponicsally grown beetroot plants to activate plant proteins and enzymes for plants' wellbeing.…”

“…Besides, these two minerals improves nutrients (mostly nitrogen and phosphorous) absorption capacity in plant, therefore increase plants' ability to produce flowers and fruits. Consequently, using epsom salt promises a bushier and greener garden (Orlovius, 2001;Merhaut, 2007;Tilley 2016;Elbossaty, 2018) In order to assure favorable plant growth, nutrients must be available not only in sufficient amounts, but also in appropriate ratios (Maathuis, 2009). Foliar spray is an effective way to avail nutrients for plant growth.…”

The study was conducted to evaluate the impact of epsom salt, rich in magnesium and sulfur content beneficial to plant, on beetroot production in aquaponics system. Media based aquaponics systems (nine units) were employed for beetroot and tilapia culture where three treatments T1, T2 and T0 were applied with three replications (R1, R2, and R3) each. Epsom salt was applied in T1 as foliar spray in the form of 5% solution in each replication, whereas same amount of epsom salt (5 g) was directly applied on vegetable bed in T2 as root application. But in control (T0) no epsom salt was used. Beetroot saplings were planted in retrospect at a rate of two saplings per growbed (replication). After thirty days, plants grew enough to support the water clarification in aquaponics, ten tilapia fry were stocked per tank (90 L) in each replication. Fish were fed commercial floating feed containing 30% protein. Although the fish growth parameters in three treatments were statistically similar, the highest mean length gain, weight gain, specific growth rate and fish production were found 5.11±1.64 cm, 30.16±0.11 g, 0.39±0.01 %/day and 26.27±2.47 tons/ha/60 days respectively in T1 followed by T2 and T0. However, response of beetroots to different treatments was statistically different. The highest average leaf area (69.79 ± 0.48 cm2), length of root (31.03±0.43 cm), weight of root (21.17±1.92 g), and production of beetroot 8.67±1.54 tons/ha/90 days were found in T1 followed by T2 and T0. Harvesting time was also reduced in epsom salt based aquaponics system. The overall production of beetroot and tilapia was higher in T1 (foliar spray) than T2 (root application) and T0 (control). Thus, the study signifies the potentialities of epsom salt in aquaponics vegetable production. However, further research is needed to verify the dose response to epsom salt in aquaponics system.

“…are rare. The low consumption elements are basic elements in plant metabolism processes and consequently in plant yield and quality (Moustafa and Omran 2006;Briat et al 2007), however, soil micronutrients availability to crop plants changes under the influence of environmental conditions, in particular soil pH (Orlovius 2001;Dords 2009). Hence, there is an immediate need to reduce the chemical fertilizers usage.…”

The effects of different fertilizers [the control with no fertilizer (C), inorganic fertilization (I), combined inorganic and organic fertilizer (IOHumax1) and (IOHumax2)] on yield and nutrients contents of two spinach varieties ("Balady and Virofly") were investigated. Significant effects of variety were observed on vegetative growth and nutrients contents. While Virofly had significantly higher leaf area (236.96 cm), stem diameter (7.43 mm) and fresh weight of vegetative and radical parts (15.05 and 0.96 g, respectively), Balady had significantly higher chlorophyll and carotene contents (0.0023 and 0.0018 g/g fw, respectively). No significant impacts of variety on vitamin C, nitrite, nitrate and oxalates contents were observed. IOHumax2 treatment (4 g/l of Humax + 100 mg/l of NHNO per plant fertigation) enhanced stem diameter and root growth and significantly improved the yield by produced plants with higher stem length, leaf number and surface area. This treatment improved the quality of plant by increasing vitamin C content and reducing nitrite and oxalates contents. No significant effects of different fertilizers were observed on NO content. A fairly balanced yield/NO and oxalates content can be achieved with combined inorganic and organic fertilizer (IOHumax1) and (IOHumax2).
