Abstract:

Cultivation of legume-cereal mixtures brings natural and economic benefits. Legumes in such cropping develop faster, ripe more uniformly and yield more stably especially in less favourable habitats as compared to legumes in pure stand. Mixed fodder contains more nutrient elements and the quality of dry matter is better than legumes in pure sowing. Such mixtures are also an important element of organic farming. The objective of this research was to evaluate the yielding of Pisum sativum cultivar with different foliage types with Hordeum vulgare cropping depending on the share of components in seeds mass in organic farming. Field experiment was carried out in 2008-2010, split-plot design, in four replications. The first rank factor was the cultivar of P. sativum: Set (bipinnate cultivar) and Terno (semi-leafless cultivar) in 2008 and Set and Ramrod (semi-leafless cultivar) in 2009 and 2010. The second rank factor was the percentage of P. sativum in the mixture: 40, 60 and 80%. In the conditions of reduced precipitation (June 2008) the increase of P. sativum percentage in a mixture caused decrease of the yields, independently of the cultivar, while in the wet year (2009) it caused increase of yields. In 2008 and 2010 the yields of mixture of H. vulgare with evaluated P. sativum cultivars were very similar but in 2009 the yield of mixture with Set cultivar was higher than with Ramrod cultivar. The increasing of percentage of P. sativum seeds in the mass of sown seeds had relatively low influence on its morphological features. Higher settling to the first and the last pod have been observed. The increasing of pod number per plants and number of pods per fruiting node has been noted in the Terno cultivar. The increasing of the P. sativum seeds percentage in the yield of mixture had positive effect on the concentration of total protein and crude fat contents, reducing crude fibre. Better quality of fodder has been obtained from mixture of H. vulgare with P. sativum Set cultivar. A cultivar of P. sativum as well as its percentage in the crop mixture had little influence on the content of phosphorus, calcium and magnesium. The increasing of potassium concentration in fodder with higher share of P. sativum seeds has been observed.
