OPTIMIZATION OF ALOPECURUS PRATENSIS L. PRODUCTION UNDER THE INFLUENCE OF CATTLE MANURE, IN BANAT PLAIN CONDITIONS. PUBLISHEDValentin Leneschi, Luminiţa COJOCARIU, D. V. LALESCU
The fodder graminaceous generally highly valuate the organic fertilizers, the fertilizer doses being proportional with production level. The cattle manure is a valuable source of nutritive elements for the meadow foxtail cultures because contains all major nutrients that this specie necessitates and also an important number of essential micronutrients.(http://www.ssca.ca/agronomics/). There is estimated that fertilizing with cattle manure, the production gains of the specie Alopecurus pratensis L. are significant ( Jankowska-Huflejt H. , 2000;Wesolowski P., 2001). The performed research concerning the dry matter production of the meadow foxtail takes into account the specie behaviour when were applied different amounts of cattle fertilizer. The goal of this paper is to find a functional dependence of the dry fodder production of the specie Alopecurus pratensis based on different amounts of fertilizer, with the purpose to obtain the technical optimum and also depending on applied technology. The biological material was the variety Alpha of meadow foxtail, seeded in each autumn of the years 2009 and respectively 2010, at distance between rows by 12,5 cm, 25 cm and by scattering method. The present paper presents the obtained results in the specie Alopecurus pratensis, cultivated at different distances between rows and fertilized with different doses of cattle manure (Doze 1- 20t ha, Doze 2- 40t ha, Doze 3- 60t ha and Doze 4- 80t ha). The largest dry matter production were found in all variants for the maximal dose of cattle manure (80 t ha). However, the technical maximum of dry matter was as following: to 7784,3 kg ha -1 for an amount of 68,98 t ha -1 cattle manure and for 12,5cm distance between rows; to 7688,9 kg ha -1 for an amount of 69,29 t ha -1 cattle manure and for 25cm distance between rows, and to 8438,8 kg ha -1 for an amount of 71,97 t ha -1 cattle manure and for sowing by scattering .
