The study evaluated chemical composition of 13 breeding strains and 3 cultivars of Lolium multiflorum using standard analytical methods and applying the NIRS method. The experimental material derived from a field experiment established in 1998 in Plant Breeding Szelejewo. lt was found that out of all Lolium multiflorum cultivars and breeding strains, in relation to the model – ‘Lotos’ cultivar, ‘SZD-SZ-200’ and ‘POB-GN-144’ were characterised by advantageous content of crude protein, ‘RGI-P364’ - by a high sugar level, ‘POB-GN-144’ and ‘RGI-P382’ - by low levels of lignins and ‘RGI-P287’ – by a good total calcium concentration. The performed analyses showed a considerable consistency between assays obtained using the NIRS method and those arrived at by standard chemical methods with regard to crude protein, NDF and ADF. On the other hand, significant differences were recorded in results associated with concentrations of hemicelluloses, calcium, magnesium and phosphorus. The performed experiments allowed concluding that, provided appropriate calibration of spectrophotometers was performed on the basis of native analytical material, it is completely rational and justifiable to use the NIRS method for qualitative assessment of grass cultivars and breeding strains.
During 3 years (1990-1992) the pot experiment on 15 soils with the red clover and Italian ryegrass were conducted. Each of soil was without Mg treatment or with treatment of 0.04 g Mg/1 kg of the soil. The soils were very differentiated in the content of various forms of magnesium (2.9-22.7 mg Mg/100 g of the soil), humus (0.9-2.7%) and soil particles <0.02 mm (6-25%). The content of different form of Mg in the soil (active, exchangeable, available after Schachtschabel and EUF and nonexchangeable) depended first of all upon thDuring 3 years (1990-1992) the pot experiment on 15 soils with the red clover and Italian ryegrass were conducted.

The content of different form of Mg in the soil (active, exchangeable, available after Schachtschabel and EUF and nonexchangeable) depended first of all upon the sorption capacity, the content, later on the humus and at least on the content of soil particles <0.02 mm. Application of magnesium increased the yields of red clover and Italian ryegrass when soil contained 1 3.5-4.5 mg of exchangeable magnesium per 100 g of the soil. The increase of yield of plants after Mg application could be predicted most accurately on the basis of the content of Mg (extractable in 0.01 M CaCl₂) and in smaller degree on the basis of the content of available detected by EUF, and Schachtschabel methods.e sorption capacity, the content, later on the humus and at least on the content of soil particles <0.02 mm.
