ORGANIC AND MINERAL FERTILIZATION OF TEMPORARY GRASLANDS – ECOLOGICAL MEAUSE AND THE EFFICIENCY ON ENHANCING FODDER PRODUCTION SCENARIO IN THE HILLS`AREA OF OLTENIA REGION

It is commonly known manure is a complex organic fertilizer. Manure contributes to the fertility of the soil by adding organic matter and nutrients such as: nitrogen or phosphorus wich can be found goth as an organic and mineral matter in equal parts and potassium wich cand be found especially in soluble form in water (Gooke, 1971, quoted by Moga. I, and colab. 1996)

ADAPTING PERENNIAL GRAMINACEE PRODUCTION FOR HILLS`AREA OF OLTENIA REGION

The present paper aims at presenting the importance of perennial graminacee introduction for temporary grasslands, which were adapted to the ecological conditions. Moreover here are some species of graminacee which were adapted to the present conditions

THE INCREASING OF FODDER YIELD IN THE CENTER PART OF OLTENIA FOR SUSTAINABLE DEVELOPMENT OF LIVESTOCK

The environmental conditions from experimental area (ARDS Simnic, Dolj, Romania) offers favorable conditions for temporary meadows that give increased yield of quality feed. The proper fertilizing schedule combined with a good management contributes to a long permanence of temporary pasture

RESEARCH ON CLOVER CROP MIXED WITH PERENNIAL GRASS FORAGE IN THE CENTRAL AREA OF OLTENIA

In the central area of Oltenia, Trifolium pretense specie can be used as perennial legume mixed with Dactylis glomerata or Lolium hybridum for temporary meadow. Between these two experimeted mixtures the best results were obtained by Trifolium pratense and Lolium hybridum that realized 6.25 t/ha dry matter as an average value on three experimental years. The meadow including 80 % Dactylis glomerata + 20% Trifolium pratense without fertlization, lead to the lowest forrage yiled, while the yield obtained by the mixture 40 % Lolium hybridum + 60% Trifolium pratense was much higher

THE EXPERIMENTAL RESULTS REGARDING THE INFLUENCE OF THE COMPOST AND OF THE AMENDAMENTS TO THE TEMPORARY MEADOWS FROM SCDA SIMNIC

Both the simple mixture of graminaceae and pulverize and the complex react very weel both to the organic fertilization and the chimical one with nitrogen.The amount of the crop obtained in the mictures with organic fertilization, with oxidat between 1,3 – 2,1 t/m d.s. at the simple mixture and 1,8 – 2,6 t/ha d.s. in the case of the complex mixture of nitrogen. The nitrogenous, too has substantially contributed to the encreasing of the crop, ensuaring a growth of over 3,6 t/ha d.s. (N120) at the simple mixture, respectively over 5,4 t/ha d.s. (N120) at the complex mixture

PERFORMANCE OF ALFALFA VARIETIES IN THE IRRIGATED PURE CULTURE IN THE HILLY REGION OF OLTENIA

Ecological Zoning of various species of fodder plants targeted choice of the mostsuitable species for each region and their locations in succession to lead to theachievement of optimal production for each crop in hand, and a whole assortment of crops.In this context alfalfa, green areas is recommended, culture is the most valuableprotein.Among the varieties of alfalfa taken experimentation best adaptedfollowing:Magnat (7.5 t / ha dry metter ), Daniela (7.3 t / ha dry matter ) and Sandra (7,1 t / ha dry matter ).If we refer to crude protein production, it ranged between 711,9- 1826,7 kg /ha

RESEARCHING RESULTS ON THE FERTILIZER APPLYING ON SOWN PASTURES ON LUVISOIL FROM ARDS SIMNIC

The sown pastures that are made of valuable grasses and leguminous fodder species have a high productive potential which can only be capitalized byproper fertilization. The mineral fertilizers are applied on a large scale due to their easy absorbtion by plants because they are soluble and immediate effect. Thenitrogen fertilizers applied on several rates substantially contributes to theobtaining of high harvests of fodder of good quality ensuring a better rescheduling of production

RESEARCHES ON THE APPLYING TIME OF FERTILIZERS AND THEIR TYPE ON SOWN PASTURES FROM CENTRAL AREA OF OLTENIA

Proper use of fertilizers on pastures assumes the detailed knowing of technical aspects related with the type of the fertilizer, the combination, the rate, the splitting, the time of applying, all these things making the object of extensive researches. Regarding the chemical fertilization, on sown pastures there can be used, both, simple fertilizers (ammonium nitrate, nitrocalcar, superphosphate, potassium salt, etc.) and complex ones in different formulas

THE REACTION OF SOME GRAMINACEAE AND PERENNIAL VEGETABLES FODDER IN ORDER TO CREATE SOME TEMPORARY MEADOWS IN THE CENTRAL PART OF OLTENIA

The perennial fodder plants represent a main (important) source of food for animals.The results obtained in our country led to the cration of new variety and hybrids whit a high crop potential and the creation of differentiate technologies on large ecological zones.In this way, on the luvosoil from SCDA Șimnic – in order to enlarge the temporary meadows in crop – there have been obtained good results at the species: Dactylis glomerata, Arrhenatherum elatius, Bromus inermis, Medicago sativa, Lotus corniculatus, Onobrichis viciifoli
