Sažetak
In this study we examined two types of field pea (afila – semi-leafless and the normal type) in two mixtures (85:15% – field pea:oats ; 70:30% – field pea:oats). The goal was to compare the normal and the afila type in two different proportions with oats, as well as compare them with single crops. The relations between mixed crops were evaluated on the basis of yield, land equivalent ratio – LER, aggressiveness – Ag, actual yield loss – AYL and system productivity index – SPI. The obtained results show that there were no statistically significant differences between the yield of oats across various combinations of both types of pea or the calculated values for Ag, AYL and LER. Differences were found between combinations and monocultures, yield of the field pea and SPI feature at a 0.01 statistically significant level. Yield for the normal type of field pea was higher in mixtures than in a single crop. Yield values were higher in all combinations for the normal type of field pea (26.86 t ha -1) compared to the afila type (10.48 t ha -1). On average, higher efficiency in the utilization of land (LER) compared to the single crop was observed in the combination with the normal type of field pea. Oats also showed higher yields in combination with normal field pea (3.06 t ha-1) compared to the afila type (1 t ha-1) on average. Aggressiveness (Ag), actual yield loss (AYL) and system productivity index (SPI) were higher for mixtures of normal field pea and oats (70:30%), which indicates the priority of establishing crops of normal types of field pea and oats. Based on the obtained results, we may conclude that semi-leafless types are better for monoculture, while normal types are better for higher yields and mixtures with oats.
