“…The amount of potassium in peanut shell compost was 50 times more than in peat, leading to an increase in the medium's potassium level. The higher nitrogen and lower carbon levels of peanut shell compost compared to peat caused a decrease in the C/N ratio of compost treatments (Gayasinghe et al 2010). This ratio was lower than the allowed level, which is suitable for growing ornamental plants.…”

“…This may be due to the large C/N ratio in the control bed and the decreased need for nitrogen of the plant, compared to the 15, 30, 45 and 60 % treatments with peanut shell compost. Gayasinghe et al (2010) used manure compost (CMC) and synthetic compounds (SA) as an alternative to peat in cultivating Tagetes paluta and concluded that plant height, the number of flowers for each plant, the dry and fresh weights of stems, root length and dry and fresh weights of roots increased in the combined treatment using 40 % SA and 60 % v/v CMC. The nutrient concentration in dracaena leaves was within the presented range as shown by Denis et al (2003), denoting the effectiveness of nutrient range for plant growth.…”

“…Some studies show that peat can be replaced by organic wastes such as municipal wastes, sewage sludge, livestock manure, paper, waste from pruning, and fungi beds and other organic waste after composting (Gayasinghe et al 2010). Investigations of Ficus benjamina variety Starlight in a growth medium containing a ratio of 1:1 of peat to olive waste (as volume) showed the plant growth to be very high during 10 months (Chen et al 1989).…”

Background The reuse of organic wastes in agriculture is an appropriate method of environment management. Most plants with ornamental leaves are cultivated in soilless media, in which peat is the basic medium; but the use of peat is questionable due to ecological damage to the environment and economic disadvantages to ornamental plant producers. Peanut shells as remained wastes of cultivating peanut has a considerable volume, compost of which can be used as available sources of ornamental plants medium. A pot experiment was conducted to investigate the possibility of using peanut shell compost in the appropriate bed in the cultivation of ornamental plants. Dracaena marginata was selected as the test plant. The control treatment consisted of a 2:1 ratio of peat to perlite, and peat was replaced by 15, 30, 45, 60 and 100 % v/v of peanut shell compost. The study was done based on a complete randomized design in three repetitions in the ornamental plants and flowers research station, Lahijan, Iran. Results The results showed that the bulk density of the planting beds decreased with the addition of peanut shell compost in comparison to the control. Peanut shell compost increased total nitrogen and available phosphorus and potassium of the media. Peanut shell compost increased plant growth indices, but the growth was reduced in 100 % in the compost treatment. The compost led to increase in nutrient uptake by plants. Conclusion In conclusion, it became known that peanut shell compost is an appropriate alternative to peat as the growth medium of ornamental plants. Because of the favorable properties and high porosity, peanut shell compost can be mixed with low-porosity substrates and applied as a substitute to peat in the cultivation media. It is not suggested to increase peanut compost level by 60 and 100 %.

Peanut Shells as the waste left from peanut planting, which considerable amount of compost can be used as available resources to replace with peat in cultivation of Ornamental plant growth media. So, in this experiment, five treatments in a completely randomized design with three replications were conducted in outdoor in Lahijan ornamental plants Research Station. Treatments were included: 2 peat + 1 perlite + 0 Shells Peanut composts (control), 1.5 Peat + 1 perlite + 0.5 Shells peanut compost, 1 Peat + 1 perlite + 1 Shells Peanut composts, 0.5 Peat + 1 perlite + 1.5 peanut shells compost, 0 peat + 1 perlite + 2 peanut shells compost. In this experiment growth index of violets are included, number of flower, plant height, fresh and dry weight of canopy, root length, root fresh and dry weight, and physical and chemical properties of substrates were measured. The results showed that replacement of Shells Peanut compost has a significant effect on, number of flowers, plant height, Dry weight of canopy, root fresh and dry weight in comparison to control. Increasing levels of Peanut Shells compost caused to reduce in bulk density and an increase in total porosity, Water capacity and air fill porosity.

“…Their slow renewal rate implies that peat should not only be treated as a non-renewable resource (Joosten & Couwenberg 2008), but also that alternative research is important. Several highly available food industry by-products have been identified as suitable growing media alternatives (Herna`ndez-Apaolaza et al 2005;Larcher & Scariot 2009;Dede et al 2010;Di Benedetto et al 2010;Jayasinghe et al 2010). In fact, ornamental nurseries have already incorporated coconut fibres as a partial peat substitute (Hernandez-Apaolaza et al 2005).…”

Efficacy of flurprimidol and peat alternatives on growth control of potted camellias

Potted camellias tend to grow more than desired and sometimes in association with poor flowering. Growth regulators of the triazole group have been successfully applied to overcome these issues in the past; however, recent restrictions on the group indicate that new growth retardants must be considered and tested. Concurrent with this change is the need to reduce the horticultural use of peat (potting mixture), a world resource being quickly depleted. Given these two aims, we evaluated the efficacy of flurprimidol, in combination with three peat alternatives (reused nutshells, rice husk, coconut fibres), to control the growth of four Camellia japonica cultivars. Results showed that all considered peat alternatives, especially rice husk, were suitable as partial substitutes. Results also showed that at low concentrations, flurprimidol controlled height (12Á13% reduction) and enhanced flowering (three flowers per plant vs two). However, we suggest that the growth regulator input be adjusted based on the cultivar and substrate type, as the three factors interact strongly.
