Purpose In this study, the effects of green manure and animal waste on economic of strawberry yield, fruit quality and soil fertility were investigated.
Method The experiment was set up with four replicates in a randomized complete block design. The treatments consisted of green manure parcels divided into two parts and green manure + poultry manure slurry were given to one part, and the other part was not applied complete. Seed planting was carried out in the first year of the experiment (2015) while strawberry plants were removed during the second year (2016) and the seeds of green manure plants were planted. Soja hispida [Soja] and Vigna sinensis [Cowpea] plants were mown and mixed into the soil when they were in bloom.
Results The results from the study shows that the yield realized from control plot during first year was between 10.68 and  22.33 t ha-1, second year yield was between 8.81  and 23.39 t ha-1 and  third year was 10.68 and 16.98 t ha-1. After harvest, soil organic matter content increased by 12% in the first year and 5.10% in the second year in green manure + poultry manure slurry application, the total nitrogen content increased by 75% in the first year and 10% in the second year. In the fruit, it gave higher content of Vitamin C and nitrate level.
Conclusion From our findings, it was discovered that green manure and poultry manure slurry gave better results in terms of fruit yield, quality, soil fertility and economy.


  • The main problem of modern societies is to ensure the sustainability of the scarce resources (nature) they use to meet their needs without losing these features. This approach is valid in agricultural production activities as in every field. Organic agriculture is a reflection of the understanding of sustainability in agricultural activities.


  • The article is discussed in order to evaluate the wastes generated in the agricultural production process within the scope of organic agriculture production principles and to develop economically feasible alternative production methods. Accordingly, the study concluded that instead of expensive production inputs (chemical fertilizers), using wastes (poultry manure and herbal wastes) generated in the agricultural production process would be more economical and efficient in agricultural production.


  • The article is thought to contribute to the literature on two important issues, as well as reaching results that support previous studies in this field. The first is to determine low-cost alternative production inputs by evaluating the wastes (poultry manure and herbal wastes) generated in the agricultural production process for strawberry cultivation, which is an important economic product, and the second is to prove that it is economically applicable to real life.
