Vertical Farming

Consumption of basil (Ocimum basilicum) has been increasing worldwide in recent years because of its unique aromatic flavor and relatively high concentration of phenolics. To achieve a stable and reliable supply of basil, more growers are turning to indoor controlled-environment production with artificial lighting due to its high environmental controllability and sustainability. However, electricity cost for lighting is a major limiting factor to the commercial application of indoor vertical farming, and little information is available on the minimum light requirement to produce uniform and high-quality sweet basil. To determine the optimal daily light integral (DLI) for sweet basil production in indoor vertical farming, this study investigated the effects of five DLIs, namely, 9.3, 11.5, 12.9, 16.5, and 17.8 mol·m−2·d−1 on basil growth and quality. ‘Improved Genovese Compact’ sweet basil was treated with five DLIs provided by white fluorescent lamps (FLs) for 21 d after germination, and gas exchange rate, growth, yield, and nutritional quality of basil plants were measured to evaluate the effects of the different DLIs on basil growth and quality. Results indicated that basil plants grown under higher DLIs of 12.9, 16.5, or 17.8 mol·m−2·d−1 had higher net photosynthesis, transpiration, and stomatal conductance (gS), compared with those under lower DLIs of 9.3 and 11.5 mol·m−2·d−1. High DLIs resulted in lower chlorophyll (Chl) a+b concentration per leaf fresh weight (FW), higher Chl a/b ratios, and larger and thicker leaves of basil plants. The shoot FW under DLIs of 12.9, 16.5, and 17.8 mol·m−2·d−1 was 54.2%, 78.6%, and 77.9%, respectively, higher than that at a DLI of 9.3 mol·m−2·d−1. In addition, higher DLIs led to higher soluble sugar percent and dry matter percent than lower DLIs. The amounts of total anthocyanin, phenolics, and flavonoids per plant of sweet basil were also positively correlated to DLIs, and antioxidant capacity at a DLI of 17.8 mol·m−2·d−1 was 73% higher than that at a DLI of 9.3 mol·m−2·d−1. Combining the results of growth, yield, and nutritional quality of sweet basil, we suggest a DLI of 12.9 mol·m−2·d−1 for sweet basil commercial production in indoor vertical farming to minimize the energy cost while maintaining a high yield and nutritional quality.

Nitrogen plays a vital role in the growth, development and nutritional quality of Chinese chive, which is an important leafy vegetable. The effects of improved Hoagland nutrient solutions on the nutritional quality and physiological characteristics of three Chinese chive cultivars (Saisong, Pingjiu No. 4 and Pingjiu No. 8) were investigated by modulating the ratio of nitrite nitrogen (NO<sub>3</sub><sup>&ndash;</sup>-N) to ammonia nitrogen (NH<sub>4</sub><sup>+</sup>-N). Improved Hoagland nutrient solutions with NO<sub>3</sub><sup>&ndash;</sup>-N to NH<sub>4</sub><sup>+</sup>-N ratios of 50:50 and 75:25 could effectively promote the accumulation of soluble protein, soluble sugar, vitamin C and proline; decrease the malondialdehyde content; and induce the superoxide dismutase and peroxidase activities of the three cultivars. It is strongly suggested that NO<sub>3</sub><sup>&ndash;</sup>-N to NH<sub>4</sub><sup>+</sup>-N ratios of 50:50 and 75:25 improve nutritional quality and promote growth and are thus suitable for Chinese chive growth under hydroponic culture.

Worldwide, French beans (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), and kales (Brassica oleracea L. var. acephala) are considered economically important food crops. There is a rapid decline in their yield due to severe soil degradation. Thus, high commercial fertilizer inputs are crucial, though they remain expensive and inaccessible to resource poor farmers. We investigated the comparative performance of composted black soldier fly frass fertilizer (BSFFF), conventionally composted brewer's spent grain (BSG), commercial organic fertilizer (Evergrow), and mineral [nitrogen, phosphorus, and potassium (NPK)] fertilizer on growth, yield, N use efficiency, and nutritional quality (crude protein, crude fiber, crude fats, ash, and carbohydrate concentrations) of tomatoes, kales, and French beans under greenhouse and open-field conditions for two seasons. The fertilizers were applied at rates equivalent to 371 kg of N ha−1. For each crop, the plots were treated with sole rates of BSFFF, BSG, Evergrow, and NPK to supply 100% of the N required. Additional treatments included a combination of BSFFF and NPK, and BSG and NPK so that each fertilizer supplies 50% of the N required. The control treatment consisted of unfertilized soil. Results show that vegetable yields achieved using a combination of BSFFF and NPK were 4.5, 2.4, and 5.4-folds higher than the yield from the control treatment for tomatoes, kales, and French beans, respectively. The combined application of BSFFF and NPK produced 22–135%, 20–27%, and 38–50% higher yields than sole NPK for tomatoes, kales, and French beans, respectively, under both greenhouse and open-field conditions. The highest agronomic N use efficiency was achieved in sole BSFFF-treated plots compared to sole BSG and Evergrow. The N taken up by the vegetables was significantly higher when BSFFF and NPK were integrated. Vegetables grown using a combination of BSFFF and NPK had the highest crude protein and ash concentrations. Our findings demonstrate that the integration of BSFFF and NPK in vegetable cropping systems at the recommended rate of 1.24 t ha−1 BSFFF and 322 kg ha−1 NPK would improve soil health, boost yield, and nutritional quality of vegetable crops.

Effect of ammonium and nitrate ratios (0:100, 25:75, 50:50 and 75:25) on nutritional quality of flowering Chinese cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) with 3 cultivars were studied in hydroponics. The results indicated that, with the increasing of ammonium proportion in nutrient solution, the soluble sugar content in product organ of flowering Chinese cabbage increased gradually, but Vc content decreased gradually. Enhancement of ammonium by 25% or 50% in nutrient solution increased the soluble protein content in leaf significantly, while it increased gradually in stalk with the increasing of ammonium proportion. Free amino acids in product organ of flowering Chinese cabbage were improved significantly by enhancement of ammonium in nutrient solution. Integrated nutritional quality of flowering Chinese cabbage in 25% ammonium enhancement treatment was better than others under hydroponics condition.

Summary Modifications in growing techniques can affect the yield and nutritional quality of various cultivated plants. Among them, the use of biostimulants is environmental friendly method of stimulating crop productivity, stress resistance, and affecting yield or chemical composition of the plants. The aim of the investigation was determining of the effect of biostimulant treatment on yield and its quality of carrot grown for summer harvest. The experiment was carried out in 2009-2011 in the experimental station of the University of Agriculture in Krakow, south Poland. Two experimental factors were taken into consideration: (1) cultivar: Nandrin F1 and Napoli F1 (2) dose of Aminoplant (foliar application): 1.5 and 3.0 dm3∙ha-1 and control (without Aminoplant). Total and marketable yield, root length, its diameter, leaf mass and leaf : root mass ratio were assessed. The dry matter, soluble sugar, carotenoids and nitrate ions contents were analyzed as main determinants of carrot nutritional quality. Aminoplant influenced not only carrot productivity, but mainly chemical composition of the roots. The present results also suggest that carrot reaction to biostimulant treatment was depended on a cultivar more than on environmental conditions in particular growing seasons. The significant effect of Aminoplant in a dose of 1.5 dm3∙ha-1 on the yield of roots and leaf rosette mass of ‘Nandrin F1’ appeared only in the first year of the experiment. Spraying with Aminoplant in a dose of 3.0 dm3∙ha-1 significantly increased the soluble sugars content in carrot roots of both cultivars but only in 2011. Dry matter content was also affected by biostimulant treatment mainly for ‘Napoli F1’, which showed the lowest dry matter content when sprayed with Aminoplant in a dose of 1.5 dm3∙ha-1. In 2010 control plants contained the greater amount of carotenoids, while in next year roots of plants treated with Aminoplant in a dose of 3.0 dm3∙ha-1 had more these compounds. The significant effect of Aminoplant on nitrates content in carrot roots was observed but were not repeatable in the experimental years, so different climatic conditions modified carrot reaction on biostimulant spraying.

Because it is a staple food, sustainable production of wheat is crucial for global food security. Arid and semi-arid regions are worst affected by climate change, which has resulted in poor productivity of different crops, including wheat. To this end, this study aimed to investigate the effect of foliage-applied thiourea on the growth, yield, and nutritional-quality-related traits of bread wheat. The treatments consisted of thiourea levels (control, 500, and 1000 mg L−1) factorally combined with two diverse wheat cultivars (Gandam-1 and Galaxy-2013) at different growth stages (tillering, booting, and heading) and was repeated over two years. The analysis of the data shows that thiourea treatments and the cultivars significantly (p ≤ 0.05) affected the growth, nutritional quality traits, and morphological traits, and the interaction of the two factors was also significant. Improvement in productivity and nutritional quality was observed from the application of thiourea in both cultivars. Galaxy-2013 performed best at 1000 mg L−1 thiourea application for both productivity- and nutritional-quality-related traits at the heading stage. In conclusion, exogenous application of thiourea improves the productivity and nutritional quality of wheat on sandy loam soils in semi-arid regions; however, for wider recommendations, more trials may be conducted across various agro-ecological regions.
