Cotton yield is affected by several factors some of which are related to soil characteristics, and some are related to farmers’ input. The effect of these factors on cotton yield is studied in the current research. A total of 296 samples of soil characteristics and other factors were collected from agriculture department (GIS system) and farmers. Soil characteristics include soil pH, electrical conductivity (EC), organic matter (OM), phosphorous (P), potassium (K), calcium carbonate (CC), and micronutrients as zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), and boron (B). The variety of seed, pesticide, fertilizer, etc., was also considered. A multiple regression model was used to study the effect of these factors on cotton yield. The results showed that of variation in the cotton yield is explained by these factors. It was also revealed that EC, pH, saturation, OM, P, Zn, Cu, Fe, and B have a significant contribution to the cotton yield. Some other factors like fertilizer (nitrophos, nitrogen, and urea), previously sown crops (wheat and corn), type of seed, chemical coating of seed, type of water, way of cultivation, and use of compost have also a significant contribution in the yield of cotton.
