Determination of the effects on tomato (Solanum lycopersicum L.) growth and yield of poultry manure application

This study was conducted to investigate the effects of different poultry manure application (0 kg da-1, 600 kg da-1, 1200 kg da-1) on growth and yield of tomatoes cultivation in greenhouse conditions. For this purpose, the values of growth (fruit diameter, fruit weight, number of fruit, pH, acidity, fruit firmness, total soluble solids, vitamin C), yield and the mineral concentrations of fruit-plant-soil (N, P, K, Ca, Mg, Fe, Zn, Mn, Cu) were determined. As a result of this study, the application of 1200 kg da-1 at fruit and plant nutrient concentrations ensures better results while the average fruit weight and yield values are determined as the most suitable dosage for application of 600 kg da-1. The application of 600 kg da-1 at soil macro nutrient concentrations has the best value while the soil micro nutrient contents are determined as the most suitable dosage for application of 1200 kg da-1 and the minimum values of mineral nutrient contents were obtained control application (0 kg da-1). It has been observed that the chicken manure application with basic chemical fertilizers provides significant contributions in yield and quality parameters and it is considered that the dose of 600 kg da-1 will not be a risk for soil salinization problem and can be evaluated as an economic dose over a long period of us
