WITH PARTHENOCARPIC FRUITINGFlorin Constantin IACOB, Gheorghe CÂMPEANU, Nicolae ATANASIU, Elena CATAN,Gabriela NEAAbstractUniversity of Agronomic Sciences and Veterinary Medicine of Bucharest,59 Mrti Blvd., 011464, Bucharest, RomaniaCorresponding author email: fliacob@info.uaic.roThis study was conducted during 2009-2010 in southern Dâmbovita County, in order to determine the impact of foliarfertilization on the production and its quality on five hybrids of cucumber gherkins: Promisa, Trilogy, Karaoke, Kybriaand Componist and were obtained results with significant differences. Hybrids were planted in the same soil type andbearing the same climatic conditions, differences occurred in the production were attributed to variantsstudied. Immediately after establishment of experimental culture, fertilization were made every 10 days withapplication of bio-fertilizer as appropriate technological practices, also were performed observations andmeasurements on the production and quality of the varieties analyzed.Key words: Cucumis sativus L., fertilization, production, quality, gherkins.INTRODUCTIONIn traditional agriculture losses of elementsused in fertilization are important, especially inthe N: P: K case, representing an importanteconomic problem (Guerrero, 1998). Fractionationof fertilization and application in criticalphases is recommended by most researchers(Cadahia, 2000; Guzmán, 2004; Pizarro, 1987).Foliar fertilization creates a positive impact onproduction in most varieties and hybrids(Solorzano, 2001).Researches regarding the technology of cultivationgherkins cucumbers were conducted during2009-2011 in the Tartasesti, DâmbovitaCounty, in the family-owned farm. Taking intoaccount the pedoclimatic conditions of thesouth area of the country and climate conditions,the applied technology present a specialimportance for obtaining high productions andhigh quality. Foliar fertilization represents arare piece of technology applied in the Lunguletu-Brezoaelevegetable basin area (whichincludes Tartasesti), solar crops of vegetablesbeing established in small areas, the most importantare field crops of vegetable, maintainedon the traditional principles of agriculture.Have been attempted combining two elementsof technology, leading and trellising mode of69the plant with foliar fertilization regime, theapproach together of the two elements oftechnology in a area where protected vegetablecrops have a low share will lay the foundationfor future investment in the area (Petrescu,1992; Popescu V and Atanasiu N., 2001)Following research it was observed that thedriving of the plant and foliar fertilization ledto positive results on the production and qualityof gherkins cucumbers, results that support thenecessity of introducing in the technology ofgherkins culture new elements that will comeas a completion of higher genetic potential ofnew hybrids being subject of this study. Themain purpose of this research represents theintroduction of new elements of technology inparallel with the discovery of better hybridsadapted to the climatic conditions of the area.Therefore, research will highlight the followingaspect:- obtaining high yields as a result of foliarfertilization and of the plant leading type ontrellises;- correlation between growing phased andtotal production under the influence oftechnology elements;- productivity of analyzed hybrids.
MATERIALS AND METHODSFor biological material selection were takeninto account first of all the necessity of usinghigh temperature resistant varieties (the Southarea of the country and growing in protectedareas) and very productive. For this wereidentified five RZhybrids (Kybria, Karaoke,Compomist, Trilogy si Promisa). Theexperience was polyfactorial one whereexperimental factors have been the following:- Factor A – Hybrid:A 1 – Kybria;A 2 – Karaoke;A 3 – Compomist;A 4 – Trilogy;A 2 –Promisa.- Factor B – Leading mode:B 1 – The plants were led up to a maximumheight of 2.5 m. The first 30 cm weremaintained without fruit, next 50 cm one fruiton each side sprig preserving all the fruits ofmain stalk nodes, and from ˜ 80 cm has notbeen intervened on the fructification.B 2 – The first 50 cm were maintained withoutfruit, then for the next 50 cm were kept onefruit on side sprig and all the fruit on the mainstem and from 100 cm height were keptabsolutely all the fruit, as illustrated.- Factor C – Foliar fertilization:C 1 – CROPMAX: biological product accordingE.U.C 2 – BIONAT PLUS: product approved bypermit no. 391/16.03.2007.C 2 – BIOLEAFZ: is a liquid plants stimulant.RESULTS AND DISCUSSIONSDuring 2009-2011 the results of plants growthconcerning the stem growing height, number ofsprigs of orders I and II, number of leafs,number of female flowers and number ofrelated fruits appeared, showed somedifferences, thus demonstrating the influence ofexperimental factors on production and itsquality.As a result, at some variants the hight of plantswas different and the number of fruits wasinfluenced by the leading mode of the stem andapplied foliar fertilizer. The differences weremore pronounced at the beginning ofvegetation, first floor of 30 cm and 50 cm highwhich has not have retained fruit having aobvious influence.Figure 1. Trellising schemes used in researchFoliar nutrient solutions applied at the samestage of development of the plant, regardless ofhybrid, had a positive influence on thevegetative growth for variant B 2 (50/100/250),plants having a strictly vegetative growthperiod until they reached the 50 cm height(compared with plants where it was appliedvariant B 1 -30/80/250).In 2009, concerning increase in height ofplants, it was found that the variant B 2 -50/100/250 had higher results compared to B 1 -30/80/250.In 2010, the trends were similar, hybridreaching 234 cm led by the same scheme andfoliar fertilized with the same solution.Maximum height reached in 2010 is detainedalso by Compomist hybrid, but led to thescheme B 1 -30/80/250 and foliar fertilized withCROPMAX.CONCLUSIONSPlants grown after B 1 -30/80/250 leading modeshowed less vegetative growth than plantsgrown after B 2 -50/100/250 leading mode.70
