Effect of phosphorus and potassium fertilization on growth and yield of corn plants under different natural soil amendments
Journal Title: Scientia Agriculturae - Year 2015, Vol 9, Issue 2
Abstract
A field successive experiment was carried out employing sandy soil to clarify the role of natural soil amendments and varied levels of P and K fertilization on growth and yield of corn (Zea mays L., cv Giza 10) crop. The experiment was carried out to evaluate the effect of compost and bentonite as combined with different phosphorus and potassium fertilization combinations on corn plants. Each amendment was added to soil at a rate of 5 ton fed-1 in combination with three levels of P (40, 60 and 80 kg fed-1) were combined with two levels of K2O (40, 60 kg fed-1) and one level of N (150 kg fed-1).Data obtained from the experiment indicated that increasing P and K fertilization increased growth and yield parameters were higher in compost compared to bentonite or no amendment application condition. Generally, interactions among P and K fertilization were found to affect significantly growth, yield and nutritional status of corn plants. Increasing N fertilization level increased nutrient content under compost and bentonite condition. However, increasing P fertilization level decreased N opposite to Ca and Mg contents; those of P and K content were less affected to increasing P fertilization.
