The effect of distance between rows on sowing and of mineral fertilisers on a complex forage mixture in condition specific to Transylvania Plain.

Lately an increasingly importance is shown to complex forage mixture. In Transylvania Plain detailed studies are still required for highlighting the most suitable forage mixture for this area. These are needed also to support farmers, especially in the actual context when both agricultural and livestock systems are crossing a transitional period, characterized by decreases in production from year to year. Our study aims to follow the behaviour of a complex forage mixture formed by Trifolium pratense (15%), Lolium perenne (20%), Festulolium (25%), Festuca arundinacea (25%) and Phleum pratense (15%) under the influence of different technological inputs. The species were sown on two different distances between rows, namely 12.5 cm and 25 cm and it was fertilized with 4 different doses of mineral fertilizers and Ammonium nitrate (33.3%) in 4 different doses, as follows: V 1 -control variant, unfertilized, V 2 - N 50 P 60 K 80 , V 3 - N 75 P 60 K 80 , V 4 - N 100 P 60 K 80 . The present study comprises data registered in 2013, data related to green mass and dry matter (DM) production and floristic composition of the mixture studied. The results registered helped us to identify the most efficient technology both from ecologic and economic point of view, able to provide increased productions and high quality forage.
