A Structural Equation Model has been used to investigate the multidirectional causal relationship among agricultural characteristics such as nitrogen content in the soil (kg/ha), Rice yield (kg/ha), nitrogen uptake by rice (kg/ha) and organic carbon (kg/ha). There using time series data of experimental project on Raipur district of Chhattisgarh from 1993 to 2017, this paper investigates the separate but simultaneous impact of different character on yield. After investigation through the structural equation model, a highly significant and positive effect found for nitrogen content on nitrogen uptake & yield. Nitrogen uptake positively affects on yield, but organic carbon negatively and lowest affects on nitrogen uptake & yield. Our paper provides a technique for a better understanding of multidirectional relationship among several key characteristics. By the technique inclusion of many relevant variables are possible and can be weeding out irrelevant characters. So that, by path analysis researcher can search specific relations among the variables.
