A field experiment was conducted during April 2017 to April 2018 at the jackfruit orchard in Madhupur tract of Shibpur, Narsingdi. To observe the soil physical conditions and to determine the changes in soil chemical properties aroid (Colocasia esculenta), ginger (Zingiber officinale), turmeric (Curcuma longa) and chilli (Capsicum annuum) were grown with jackfruit tree (Artocarpus heterophyllus). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The results revealed that soil temperature was reduced by 3.37-9.25% in different crop associated agroforestry systems (AFs) than open seasonal crop field, while soil moisture was found to be increased by 10-20%.  In general, all studied parameters of soil chemical properties both in agroforestry and non-agroforestry fields increased after experimentation from their respective initial fields. Soil pH was raised by 1.5-8.84% in Jackfruit based AFs than open field after experimentation. As compared to open crop field after study, total nitrogen of the soil was promoted by 9-19% in seasonal crop associated AFs. Jackfruit based agroforestry with different seasonal crops increased soil organic carbon (SOC) by 3-10% compared to open field after study. Results also revealed that soil organic matter (SOM) were increased by 3.35-8.62% in AFs fields after experimentation than open field and by 3.36-19.39% than AFs fields before study.
