“…In experiment 1, we found that 50% biochar significantly reduced the plant height of Viola, while in experiment 2, only cultivar affected final plant height. Researchers studying Chrysanthemum coronarium L., Calathea insignis, Solanum lycopersicum L., and Tagetes erecta L. have shown positive effects of biochar in rates ranging from 3-20%, which is less than our two highest rates [9,44,45]. Alternatively, studies conducted by Furtado et al [29] found that plant height was reduced in sunflower (Helianthus annus L.) when poultry biochar rate was increased beyond 5%, and Rajkovich et al [46] found that the growth of corn was reduced when food waste biochar rate was increased to 7%.…”

“…Biochar is a charcoal-like carbon rich substance obtained from pyrolysis of plant material or organic waste in an anoxic environment [8][9][10]. The particle size, quality, and toxicity of biochar differs by the methods used, substrate, and temperature applied during the manufacturing process [11][12][13].…”

“…Hardwood biochar usage is more prevalent in greenhouse horticultural crops in as well as field production [20,21,24,25]. In a study conducted by Ali and Mjeed [9], Chrysanthemum plants grown with eucalyptus biochar had increased plant height, fresh weight, and more buds and flowers. In other studies [26], wood-derived biochar addition resulted in increased plant growth and productivity by increasing plant height in tomato, and increasing leaf area in both tomato and pepper.…”

Increasing costs and environmental issues regarding excessive use of peat moss is impacting the horticultural industry. Biochar is a valuable substrate additive that has the potential to reduce the use of peatmoss in greenhouse production. However, its varying effects on ornamentals requires that individual species and cultivars of crops must be evaluated to determine the threshold for benefits. Viola cornuta is a high value ornamental crop; however, information on how different rates of biochar rates affect productivity and physiology of Viola cultivars in container production is not known. To determine if biochar rates could increase the productivity of Viola, we mixed a peat-based substrate with 10, 25, and 50% (w:w) hardwood biochar in two studies on four cultivars. Without fertilizers, 10 and 25% biochar improved plant biomass, growth, root length, and flowering, but 50% biochar was found to have negative effects on plant growth and flowering. Cultivars varied in their response to biochar rates. When fertilizer was applied in the second experiment, biochar rates did not impact growth parameters or flowering. These results suggest that up to 25% biochar can be used in Viola production without detrimental impacts. However, 50% biochar can be used with the addition of fertilizer without negatively affecting plant growth. Biochar can have a short-term impact on the growth characteristics of Viola plants in container production, but fertilization and growing period of Viola may influence these effects. These results indicate that biochar could be the suitable replacement for peat moss, with up to 50% biochar rate in Viola production reducing the environmental and economic burden for peat moss.

“…The Physical and chemical properties of the soil used in the study: was shown in Table 1 defined by [17,18,19]. The concentration of (H A ) in liquid fertilizer used was 87% and it is used as a soil additive or as a spray between plants or with irrigation water (in this research we used those four concentrations by springing on the soil within planting lines), while avoiding spray's downfall on the plants, because the spray solution leads to burns the leaves of plants.…”

The seeds of the Somar variety (local production) were planted in mid of October (after being soaked with water for 16 hours) in panels 1.5 x 2 meters. Broad bean (Vicia faba var. Somar) was studied in outdoor to determine the effect of three planting distances (20, 25 and 30 cm), four different Humic Acid (HA) concentration doses (zero, 1.5, 3.0 and 4.5) ml / liter H2O, with three replicates on some of the plant’s vegetative and yield traits; Plant Height (cm), Plant Diffusion (cm), Number of Branches /Plant, Number of Flowers / Plant, Number of Pods / Plant, % percentage of Pods Set, Total Pods Yield /plant (gm), Pod Weight (gm). The (HA) were added by spray way directly to the top of the soil with two applications, the first after 3 weeks from complete germination, while the second after branching immediately. The experiment was designed as Randomized Complete Block Design (RCBD). Based on Total pods yield / plant (gm), the best interaction between the plant distance and different concentration of (HA) was a combination of the planting distance 30 cm, and treated the soil with 3.0 ml/ literH2O.

The aim of this study was to find the effect of planting distances and spraying with different concentrations of leaf fertilizer with micronate15 on some vegetative growth traits and yield of pea variety Green Canada in non-heated greenhouses, by using three planting distance (factor A) which includes: A1:20, A2: 30, and A3:40 cm and four spray concentrations as foliar application (factor B) which includes: B0: zero, B1: 0.5, b2: 1.5 and b3: 2.5 liter of water). According to the results of this study the highest plant (124.82cm), number of branches (4.58), fresh weight,(95.94 g) and the total yield (142.41 g)were observed in the distance of planting (30 cm), while the highest value of the pod length was observed from the distance planting in 40 cm which is 8.39 cm. The concentration of 1.5 mL / liter of micronate15 gave the highest values of branches 4.53 branches, fresh weight 97.47 g, number of pods 36.73 pods, number of seeds 8.55 oats, length of the pod 8.83 cm and the total yield 150.78 g. The highest values of the number of branches 5.14 branch, fresh weight 105.72 g, the number of seeds 8.90 seed and the total yield 159.78 g were observed from the interaction between the planting distance of 30 cm and 1.5 mL / liter of nutrient micronate15. Also, the interaction between 20 cm distance and foliar application with 2.5 mL l of micronate15 gave the highest value in the number of leaves which is 53.36.
