“…Many past studies that investigated root development of cool and warm season grasses (e.g., Horst et al, 1985; Lee et al, 2004; Nektarios 2005; Sinclair et al, 2011) focused only on root mass or root dry weight as the relevant investigative parameters. Nektarios et al (2004) reported that other root architecture parameters (length, diameter, and surface area) follow the same pattern as dry weight and concluded that simple dry weight analysis was sufficient to describe rooting patterns and corresponding plant performance. However, in our study root dry weight differed only between irrigation systems at a soil depth of 0 to 5 cm, whereas differences in RLD and RD were noticeable between propagation dates (RLD), water qualities (RLD), and irrigation systems (RLD, RD).…”

Irrigating with non‐potable, saline water using a subsurface drip system has been suggested as a strategy to conserve water used for turfgrass. However, it is unknown if turfgrasses can be established from sod when saline water is applied from the subsurface. A two‐year study was conducted at New Mexico State University to investigate the establishment of ‘Princess 77’ bermudagrass [Cynodon dactylon (L.) Pers.] from sod, irrigated from either a sprinkler or a subsurface drip system, with potable (electrical conductivity [EC] = 0.6 dS m−1) or saline (EC = 2.2 dS m−1) water and propagated either early (mid‐March) or late (mid‐June). Establishment rate was calculated on the basis of percentage of green cover, which was determined by means of digital image analysis. At the end of each growing season, root samples were collected and analyzed for root weight density, root length density, and root diameter at three soil depths. When coverage data were averaged over water qualities, plots propagated in 2009 and irrigated from a sprinkler system established fastest, followed by sprinkler‐irrigated plots propagated in 2008. Drip‐irrigated plots were the slowest to reach full coverage. Root length density was higher in sprinkler‐irrigated plots than subsurface drip irrigation plots at all depths. In conclusion, early propagation of Princess 77 bermudagrass resulted in complete coverage with a denser root system at the end of the growing season, regardless of the water quality or irrigation system used. If propagated early, subsurface drip‐irrigated bermudagrass did not require supplemental irrigation from a temporary sprinkler system to successfully establish.

Olive mill waste management has been a major issue of environmental concern for all olive oil-producing countries. Several soil amendments have been used to improve the physical and chemical characteristics of rootzone profiles and mixes. Olive mill waste (OW, olive stone and pulp) in different ratios (10%, 30%, or 50% v/v) was investigated for use in production of lettuce (Lactuca sativa L., cvs. Paris Island and Corsica) and chicory (Cichorium intybus L., cv. Chicory white stem) seedlings by replacing part of the peat or perlite in the growing medium. Also evaluated was use of OW (10% or 30% v/v) in soil for production of lettuce (cv. Paris Island). The OW extracts at 10 −1 to 10 −6 accelerated seedling germination and radicle length. Under nursery conditions, the addition of OW as substrate component improved seed emergence for chicory and lettuce (cv. Corsica) but suppressed lettuce cv. Paris Island seed emergence but not mean emergence time. Olive mill waste combined with perlite in different ratios performed better regarding seed emergence compared with mixtures of OW and peat. Addition of OW in perlite and/or peat reduced leaf fresh weight and leaf numbers. Plant height decreased only in substrates where perlite was mixed with OW. Under greenhouse conditions, increased OW content in soil reduced (up to 25%) lettuce plant fresh weight compared to the control. This effect was mainly due to shorter leaves rather the number of leaves produced. Reduced plant growth occurred with reduced root fresh weight; root length was not affected by treatment. Use of soil:OW at 90:10 v/v mix can be applied to lettuce in the greenhouse; diluted OW extract and OW (at 10%-30%) may be used for seed priming and seedling production, respectively, and may increase profit.

“…Soil amendments have been used to improve physical and chemical characteristics of root zone profiles and mixes (Nektarios et al, 2003). Highly valuable materials such as soil, peat, sand, perlite, and vermiculite are commonly used as substrates for container plant production (Landis et al, 1990).…”

Olive (Olea europaea L.) mill waste disposal has led to a growing concern regarding the impact to the environment and human health. Several soil amendments have been used to improve the physical and chemical characteristics of root zone profiles and mixes. Olive mill waste (OW; olive stone and pulp) in ratios of 10%, 30%, or 50% was used for tomato (Solanum lycopersicum L.), cv. Luana, seedling production and at 10% or 30% for greenhouse tomato cultivation. Substrates containing peat and OW suppressed plant emergence and increased mean emergence time. Seedling height and biomass was reduced when OW (especially at 50%) was added to substrates, but no differences were observed in the number of leaves produced. Under greenhouse conditions, adding OW (10%-30%) in soil reduced plant height and stem diameter up to 25% compared to the control, but no differences were observed in leaf number. Plant upper biomass and root fresh weight was similar in the 10% OW and control treatments but reduced in 30% OW. Plant yield decreased (up to 36%) when 30% OW was used due to decreased fruit number rather than fruit weight. Addition of OW (10%-30%) maintained fruit firmness but decreased tomato juice pH and electrical conductivity (EC), but no differences were observed in fruit total soluble solids. The EC and K and Na contents of the nutrient were greater in outflow from OW mixtures compared to the control; no differences occurred for pH and Ca content. After a 10-week period, plants grown in 30% OW exhibited phytotoxicity symptoms and reduced growth. Use of 10% OW can be used for seedling production and in greenhouse tomato crop production, maintaining yield and fruit firmness.
