Effect of faecal sludge compost on growth, and neturient uptake of Spinach root (Spinacia oleracea.L.)

The purpose of this study was to see how faecal sludge compost affected the yield and quality of spinach (spinaciaoIeracea.L.). Plant nutrients such as nitrogen (N), phosphorus (P), and potassium (K) are abundant in faecal sludge compost (K). Sludge also returns organic matter and other nutrients to the soil, such as calcium, magnesium, and sulfur. In order to replace part of the artificial fertilizers used in agriculture, fecal sludgeuse should be promoted. For the time being, there are numerous unsolved concerns that must be investigated before human excreta can be employed widely in plant production. In Bangladesh, faecal sludge compost is the most vital for agricultural reasons.The quality of faecal sludge compost and composted bio-waste must be enhanced to fulfill the requirements in order to boost demand. Different treatments had a substantial impact on he growth, yield, and quality in this study. The T4(faecal sludge compost: soil=8:92)treatment produced the highest yield 0.47 kg/pot, fresh weight /plant 47.64g, dry weight /plant 0.42g, and dry matter content /plant 8.82 percent, leaves surface area index of large leaves /plant 8.64cm2, leaves surface area index of small leaves / plant 3.01cm2 of spinach.The number of leaves per plant, percent of seed germination per plant, and shoot length per plant of the spinach plant were all determined to be insignificantly different. On the basis of fresh weight/plant, dry weight/plant, dry matter content/plant, and yield/pot of spinach plant, significant differences were detected between treatments T3 (faecal sludge compost: soil=4:96) and T2 (faecal sludge compost: soil=8:92). The treatment with the most leaves per plant of spinach plant, the longest shoot length per plant, and the maximum moisture content per plant was discovered among the treatments. T2 treatment was determined to have the longest root length per plant.Treatment faecal sludge compost to soil ratio (8:92) had a good effect on spinach in terms of fresh weight/plant, dried weight/plant, dry matter content/plant, and yield per pot application when compared to control (To) and other treatments. Treatment T4 outperformed the other treatments in terms of spinach growth and yield. So, of all the treatments, the 8:92 ratio of faeces sludge compost to soil has shown the highest response, and the application ratio of faecal sludge to soil (faecal sludge compost: soil=8:92) composted faecal sludge is the best for uses and is suggested for plants. The nutritional quality of spinach plants increased as the rate of faecal sludge application increased, indicating that N, K, and Fe absorption ranges of spinach plants increased.The nutritional quality of spinach plants increased as the rate of faecal sludge application increased, indicating that N, K, and Fe absorption ranges of spinach plants increased. The absorption of N and K by spinach plants was found to be significantly different with control treatment To, whereas the uptake of Fe, Ca, and P by spinach plants was found to be insignificantly different.
