dc.description.abstract This experiment was conducted at Horticulture Research Station(USAMV Bucuresti)during the summer season of the year 2016. Two cucumbers varieties:Ansor F1 and Trilogy F1, planted under 10 micro plastic greenhouses. The fertilizers treatments included: 300 g/m2DIX 10 N (D); 50 and100 g/m2NovaTec (N1, N2) ;200 g/m2Orgevit(O) and unfertilized control (CA,CT). Results indicated that, there are significant differences among treatments but it was observed that for all characters studied, there is an increase with significantly difference with an increase in N level. Generally, all N fertilizer treatments (organic and Inorganic) increased thesoil (N-NH4, N-NO3, P-PO4, K) levels in soil . Results showed Ansor F1 fertilized with DIX 10 N(AD) and (Ansor F1 and Trilogy F1) with NovaTec 100 g/m2(AN2) and(TN2) gave the strongly positive effect in plant length , plant androot dry matter %. The highest content of pigments was found in Ansor F1 fertilized with DIX 10 N(AD), NovaTec 100 g/m2(AN2) and Trilogy with DIX 10 N(TD). Also observed a significant increasing in leaf content of N-NO3 representedby inorganic fertilizer treatments while the highest content of P-PO4 represented by TN2 and TO (657.86 and728.93 ppm) respectively). It is clearly showed the highest K content effected strongly with the increase of inorganic fertilizers recorded with AN2 and TN2(4513 and 4640 ppm). Results showed that all inorganic treatments gave over the normal and healthy concentration of N-NO2and K in fruits. All treatments had strongly effect with fruit length but the greatest diameter recorded with TN1 and TN2. The best yield results were recorded by Trilogy F1 fertilized with DIX 10 N(TD)and Orgevit(TO)followed by Ansor F1 with Orgevit(AO) treatment,which were obtained on the plant4.10 Kg, 4.04 Kg and 4.05Kg, respectively.There are significant variations between varieties regarding CO2concentration inresponse to the different commercial fertilizers. The highest values was observed to control CA and CT (1449.97 and 1516.76 ppm). All treatments showed significant increase in O2comparing with control variants . en_US
