Abstract
In response to the growing world population, increasing crop production has become one of the main goals to ensure enough food. Within this framework, cereals play a key role. The world’s three main grains – wheat, rice and corn – are key components of the human diet. Consumption of more animal products leads to the increased use of corn in the production of feed for farm animals. The development of corn silage production is due to its potential to obtain high yields, high digestibility and greater resistance to lodging compared to small-grain cereals such as barley and oats. In cultivation, it ensures stable yields in various environmental and agronomic conditions. It is characterized by high energy value and excellent properties for pickling. The paper presents the influence of six suspension fertilizers prepared on the basis of waste sodium-potassium phosphate from the production of polyols on the yield of maize plants intended for silage. In a 3-year field experiment, the effect of these fertilizers was compared with a control in the form of a commercial phosphorus fertilizer – Fos Dar and with a control without fertilization. In the assessment of the corn crop, the height of the plants, the amount of green mass obtained and the ratio of the mass of cobs to the green mass were used. The conducted research showed a positive effect of suspension fertilizers based on polyols on the yield of corn plants compared to the control without fertilization and no differences in relation to commercial granulated phosphorus fertilizers.
