Effect of time and supplementation in the prepration of date palm compost and growth of tagest erecta
Shekoofeh Jabarzadeh
Background: With the increasing consumption of chemical fertilizers and not returning plant residues to the soil and even burning them, the amount of organic matter in Iran's soils decreases every year and the soil turns into impervious and irreversible lumps. . Therefore, due to the fact that organic matter is the heart of sustainable agriculture, the necessity of using compost and palm waste due to the presence of organic matter, nutrients required by plants as fertilizer in agricultural lands is felt more than ever. On the other hand, nowadays, the use of organic fertilizers for the production of ornamental plants has received much attention. Using animal and poultry manure to produce compost is one of the most common ways to produce compost.
Aim: This experiment was conducted with the aim of investigating the effect of different levels of animal and poultry manure in combination with processed palm waste on the growth and breeding of parsley in the Faculty of Agriculture and Natural Resources of the Persian Gulf.
Methodology: Two experiments (seedlings and complete plants) were conducted on the obtained composts, and both experiments were conducted in a factorial manner in the form of a completely random basic design with 3 replications in a greenhouse operation. These two tests have two factors, including the type of supplementary material (substrate 2.1, 1.4 and 1.6 cow manure and 2.1, 1.4 and 1.6 chicken manure mixed with palm kernels in the form of compost along with treatment control) and the duration of compost fermentation (with four times of 45, 90, 135 and 180 days). The traits measured in the culture medium included organic carbon, density, pH, Whc, EC and the amount of phosphorus, potassium, magnesium, calcium and sodium elements. The traits investigated in the first experiment were plant height, stem diameter, leaf area, number o
