Climate change have a significant effect on agriculture in our country as well as in all over the world. Negative effects of climate change such as increasing temperature, decreasing water sources and uneven precipitation regimes have limited to agricultural area significantly. Thus, it was predicted that competition between agricultural products in terms of growing areas would arise in the next years. Assessment of relay strip intercropping and second cropping methods - that make possible to cultivate of cotton which is one of the strategic plants for our country with wheat which is most important food plant in the same year – is important. In our country, cotton is cultivated as second crop in most of the cotton region. Furthermore, in China, cotton is cultivated in huge areas by relay strip intercropping methods, but our country is not familiar to this method yet. In this review, practicality, environmental impact and profitability of these methods which are alternative between each other were examined. Previous studies suggested that cotton yields of double cropping systems were decreasing about 21-46% in comparison to monoculture cotton. On the contrary, it is observed that total output of double cropping system is 16,9-54,9% higher than monoculture system due to harvesting of two different crops. However, relay intercropping of cotton needs to labor more than second cropping of cotton because of harder integration of existing mechanization. It is possible that this relay intercropping of cotton would be featured cropping system if convenient mechanization is developed.
