| Abstract |
Using natural and synthetic soil conditioners like potassium humate and polyvinyl acetate (PVAc) that may be considered a specific management for improving soil properties which can adverse crops productivity. Field experiments were conducted in sandy soil at El-Ariash Agriculture Research Station Farm in North Saini Governorate, Egypt, the institute farm is located at 31o 7' 9.659" N Latitude and 33o 43' 52.539" E Longitude, during two successive seasons, summer season (2011) cultivated with maize and winter season (2011- 2012) cultivated with faba bean. Four rates of potassium humate and polyvinyl acetate (PVAc) were tested included in this study to evaluator their effects on some chemical properties, nutritional status and yield components of both maize and faba bean crops.
Results indicated that electric conductivity (EC) and soil reaction (pH) generally had decreased inversely organic matter content (OM) and yield components as well as their total nutrients content increased due to application of the studied treatments as compared to control at two studied seasons. Data also, revealed that EC and pH values decreased gradually by increasing the rate of polyvinyl acetate up to the third concentration, but for the rate of potassium humate up to second concentration and thereafter the values increased. Application of 2 % (C2) of potassium humate was superior in decreasing EC values, despite, application of 0.25 % (C4) of polyvinyl acetate in presence of potassium humate were superior in decreasing pH values either for maize or faba bean soils as compared to control and other treatments. Application of high rate of potassium humate recorded a high increase in OM values.
Results also revealed that both maize and faba bean yields and their total content of macronutrients were positively significant as compared to the other tested treatments when received the third concentration (C3) of polyvinyl acetate in presence of potassium humate. On the other hand, application of high concentration (C4) of potassium humate generally was inferior for these parameters.
In conclusion, the application of natural and synthetic soil conditioners like potassium humate and polyvinyl acetate (PVAc) and both in combination were the best treatments than the application any of both lonely for improve the soil chemical properties and reflected on yield components along with total content of macronutrients under conditions of experiment
