Analyzing the effects of potassium fertilization on the yield and total N, K2O and P2O5 export of tomato plants
The tomato ( Solanum lycopersicum ) is a crop that is characterized by considerable nutrient export because of its intensive growth, development, fruiting, and high biomass production. The purpose of this study is to determine how single-dose and split potassium fertilization impact the overall amount of nitrogen, potassium, and phosphorus exported from soils during crop harvest. A field experiment was carried out on Fluvosol (FAO, ISRIC World Soils) with K 2 O content of 20.3 mg/100g, P 2 O 5 content of 5.8 mg/100g, and mineral N of 19.6 mg/kg. It was found that the biological yield and N, P 2 О 5 and K 2 O nutrient export are significantly influenced by planting time and potassium fertilization treatments. Higher tomato fruit and biomass yields (61878.9 and 27184.9 kg/ha), along with higher nutrient export rates were observed in mid-early tomato plants. The highest yield and total N, K 2 O and P 2 O 5 export from the soil was measured at split potassium (К 80+80+80 ) fertilization treatment. A positive linear correlation between yield quantity and nutrient export was observed. The biological yield and nutrient export were shown to be significantly impacted by potassium fertilization ( P <0.05).
