Abstract:	Na območju Martjanec, blizu Murske Sobote, smo s ciljem racionalizacije pridelave v letu 2002 ugotavljali možnost pridelave strniščnih mešanic mnogocvetne ljuljke (Lolium multiflorum Lam.) in krmnega graha (Pisum sativum L.), pridobljenih z vsejavanjem ljuljke v grahovo strnišče, ki med ostanki po žetvi vsebuje tudi raztrošeno zrnje graha. Poskus je bil zasnovan kot split-plot v treh ponovitvah. Na osnovnih ploskvah smo obravnavali količino v juliju vsejane mnogocvetne ljuljke (10, 20 in 30 kg ha-1), na podploskvah pa število grahovih rastlin (povprečno 10, 25 ali 40 m-2). Ob spravilu pridelka v septembru je največji pridelek suhe snovi (5,21 t ha-1) bil dosežen z mešanico 30 kg semena mnogocvetne ljuljke ha-1 in 40 grahovih rastlin m-2, najnižji (2,45 t ha-1) pa z mešanico 10 kg mnogocvetne ljuljke ha-1 in 10 grahovih rastlin m-2. Večje število vzniklih grahovih rastlin m-2 ni imelo velikega vpliva na vsebnost surovih beljakovin v pridelku krme, zmanjšala pa se je prebavljivost pridelka s 73,5 % na 68,4 % in neto energija laktacije je upadla s 5,44 MJ kg-1 na 5,00 MJ kg-1 suhe snovi. Povečana količina semena mnogocvetne ljuljke ha-1 je povečala prebavljivost pridelka z 69,8 % na 72,4 % in neto energijo laktacije s 5,14 MJ kg-1 na 5,39 MJ kg-1 suhe snovi. Silaže, pripravljene po 10-urnem venenju so bile po petih tednih skladiščenja glede na kislinsko sestavo sicer še zadovoljive ali celo dobre kakovosti, vendar zaradi previsoke vsebnosti vode se pH ni znižal toliko, da bi omogočal trajnejšo stabilnost silaž.

Title:	BOTANICAL COMPOSITION AND FORAGE YIELD OF MIXTURES OBTAINED BY DIRECT DRILLING OF (Lolium multiflorum Lam.) INTO PEAS STUBBLE
Abstract:	In the year 2002 we studied the possibility of introducing pea seeds (Pisum sativum L.) as a stubble for the production of high quality voluminous fodder in the area of Martjanci, that is near Murska Sobota. A combination with Italian ryegrass (Lolium multiflorum Lam.) was included in the research. In July, after the peas harvest, different amounts of Italian ryegrass seeds (10, 20 or 30 kg ha-1) were drilled directly into the pea stubble. The best results of pea-ryegrass mixtures, regarding the highest dry matter (5,21 t ha-1) with various proportions of ryegrass seeds ha-1 and pea plants m-2 (average 10, 25 or 40), which were harvested in September, were achieved by the mixture of 30 kg of Italian ryegrass seeds ha-1 and, on average, 40 peas plants m-2. The increased number of grown peas plants m-2 did not have a significant impact on the value of crude protein. However, the digestibility of organic matter decreased from 73,5 % to 68,4 %, as well as the net energy of lactation, which decreased from 5,44 MJ kg-1 to 5,00 MJ kg-1 of dry matter. The increase of Italian ryegrass seeds ha-1 improved the digestibility of organic matter from 69,8 % to 72,4 % and increased the net energy of lactation from 5,14 MJ kg-1 to 5,39 MJ kg-1 of dry matter. Silages, prepared after a 10-hour withering period, had after 5 week's time in storage a satisfactory or even good quality regarding the acidity structure. However, the silages contained too much water, that is why their pH level could not decrease to the level at which longer stability of the silages would have been possible.
