INTERSPECIES RELATIONS AND YIELD OF DIFFERENT FIELD PEA/OATS MIXTURES
AbstractThe experiment was conducted in order to examine biological interaction, yield and variation of certain morphological traits in mixture with field pea as main and oats as supporting crop. Experiment included two trials, each conducted in the spring of 2015 and 2016. Each trial with two factors, the factor of the mixture (100: 15% - field pea: oats; 100: 30% field pea: oats), intercropped as additive series and two controls (100% field pea; 100% oats) and the second factor, the develpoment stage(I phase – flowering phase of field pea; II phase – seed formation of field pea). Beside the botanical share and yield of fresh weight and dry matter, plant height and number of internodes were also examined. Based on the obtained results it have been concluded that oats is highly competitive. In both years oats showed high competitiveness although it was in lower share in sowing rate. Fresh weight and dry matter yield exceed the yield of individually grown crops in 2015 (fresh matter yield – I mowing phase: field pea – 17.3 t ha-1; oats – 16.2 t ha-1; 100:15% - 21.7 t ha-1; 100:30% – 21.2 t ha-1) and 2016 (fresh matter yield – I mowing phase: field pea – 16.21 t ha-1; oats – 21.3 t ha-1; 100:15% - 22.9 t ha-1; 100:30% – 20.95 t ha-1). It have been concluded that mixtures with higher share of oats form higher dry matter yield, while the yield of fresh weight was not significantly different between the mixtures.Plant height and number of internodes in field pea have higher values when they are in a mixture than in single crop.
