Effects of municipal solid waste compost and nitrogen on physicochemical properties of soil and qualitative and quantitative characteristics of Avangard Cotton cultivar in Varamin

The growing rate of urban waste products has caused a serious problem and threatening the health of our society. Lack of attention can cause irreparable environmental damage. This study was carried out to determine the effects of combined municipal city waste MSWC with nitrogen fertilizer on cotton (cv. Avangard) characteristics and soil physicochemical properties. The experiment was conducted in the field condition using randomized complet blok design with four replications by split plot experiment at Agricultural and Natural Resources Research center of Tehran Province in Varamin on a fairly loamy soil. The treatments included: Compost at three levels (0, 20 and 40 tha-1) as main plots and nitrogen fertilizer with three levels (0, 100 and 200 kgha-1) as sub plots. The results indicated that soil salinity was increased with application of municipal waste significantly. Data also showed that the highest seed cotton yield, seed yield, lint yield and %lint were obtained by use of 40 tha-1 urban waste compost plus 100 kgha-1 nitrogen fertilizer. Use of 40 tha- 1. MSWC did not effect on soil pH. The results also showed that fiber quality parameters such as fiber lint, Fiber bund strength, fineness and fiber turn out were affected and they showed the highest quality. the organic carbon amount of soil was increased and bulk density was decreased by application of MSWC the amount of.
