摘要
Most food production systems depend on the addition of fertilizer, which is a finite source, considering their origin. Predictions on how long it is until these resources will be exhausted are not encouraging since time is limited to the level of few decades. It is therefore of huge importance to study and get to know the processes leading to increase in soybean productivity, whereas the adoption of proper management of nutrients must become the number one priority when we want to develop a sustainable vegetable production system. Through this research we aimed to evaluate the behavior of a variety (Onyx) of soybean developed by The Station for Agricultural Research and Development (SARD) of Turda under the influence of fertilization with different doses of Gülle in the specific conditions from SARD of Turda and thereby highlight the most effective dose of fertilizer both in terms of production as and quality. The experiments were established in 2013 within the SARD of Turda, located in western Transylvania Plain, Romania. Experimental variants are G1-0 t ha-1, control, G2-5 t ha-1, G3- 10 t ha-1, G4- not 15 t ha-1. The results showed that all parameters studied were favored by the climatic conditions specific to the year 2014 and by fertilization with 15 t ha-1 Gülle. Positive correlations have been highlighted between grain yield and protein yield and between nodule number and grain yield.
