Agricultural wastes management is a step toward sustainable agriculture. Peanut shelles as remained wastes of cultivating peanut has considerable volume which its compost can be used as available sources of ornamental plants medium. A factorial experiment based on randomized completely blocks design was conducted to investigate the impact of peanut shelles compost as the growth medium of Camellia in different concentrations of potassium. Fifteen treatments, every treatment at three replicates and 45 plots were used for experiment. The rooted cuttings of Camellia were planted and periodic watering with Hoagland solution was performed two times per week. After five months, the plants growth indices and the concentration and uptake nutrients were measured. Results showed that peanut shelles compost increased growth indices than in the control. In the most growth indices, the plant indicated a better response to 40% (w/w) compost and finally 60%. The results are indicator of providing the needed potassium for plant by peanut shelles compost than in the control.

The purpose of the studies was to determine the effects of media containing composts from sewage sludge and potato pulp on the flowering and decorative value of 'Butterfly Yellow with Blotch' parviflorous pansy. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm⁻³ and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm⁻³. There was no top-dressing during cultivation. The pansies for whose cultivation a slow-release fertiliser was used turned out to have most flowers, but the plants cultivated in compost with peat at the ratio 1:1 had equally abundant flowering. At the generative stage, the pansies in control media were the most decorative and those growing in 25% of compost I, 75% of compost II and 50% of compost III and IV. On the basis of plant valuation scale, quality assessment and the abundance of flowering it was found that the media containing 50% of composts were optimal for pansy cultivation.
