Survey Yield Components of Spinach under Influence of Biofertilizer and Nutrient Solution in Soils of Chengdu, Hunan, Shannxi and Xiaotanshan, China

Abstract   Several studies in the temperate region have indicated that biofertilizer have the potential to improve soil properties but may also cause serious reduction in soil productivity. We studied the effects of biofertilizer and nutrient solution application on soil properties and yield of spinach (Spinacea oleracea L.) on four soil types of Chengdu, Hunan, Shannxi and Xiaotangshan, Beijing, China. Two profile pits were sited on each of the location of the soil unit and were described before soil samples collection from the genetic horizons of each pit for analysis of soil properties. Soil total nitrogen, available phosphorus, calcium, magnesium, potassium and CEC were significantly (p<0.05) enhanced with biofertilizer treated soils of Chengdu and Hunan and spinach performance was significant compared to nutrient solution treated soils. The growth of salt-sensitive spinach was very poor on Shannxi and Xiaotangshan soils with biofertilizer. Spinach height and dry matter yield after six weeks were significantly improved (p<0.05) on the biofertilizer treated soils of Chengdu and Hunan compared to Shannxi and Xiaotangshan soils and soil with nutrient solution. These results indicated that the application of biofertilizer and nutrient solution application should done with better understanding of soil properties because of its negative effects on soils and crops.   Keywords:  Biofertilizer, Nutrients solution, Spinach, Soil properties.
