Sažetak
Kako je poljoprivreda jedan od najvećih potrošača vode, postoje brojni ogledi kako bi se poboljšala efikasnost upotrebe vode u navodnjavanju, naročito u aridnim regionima. U svetu su razvijene brojne tehnike navodnjavanja kojima se može smanjiti potrošnja vode. U ovom radu je analizirana nova tehnika navodnjavanja (AutoAgronom) u proizvodnji krastavca (dva varijeteta Rocky i Champion) kako bi se poboljšala efikasnost upotrebe vode u Izraelu. AutoAgronom je testiran u odnosu na konvencionalno navodnjavanje, odnosno navodnjavanje kap po kap. AutoAgronom (AA) sistemom se prati pH, električni konduktivitet (EC), nivo kiseonika i nitrati, gde se na ovim merenjima bazira frekvencija navodnjavanja. Dobijeni rezultati preporučuju upotrebu AA sistema u proizvodnji povrća. U proizvodnji varijeteta Champion u sistemu AA, dobijen je 20% veći prinos (9.163 kg/m2 ) nego kod istog varijeteta navodnjavanog konvencionalno. Upotrebom AA sistema količina vode za navodnjavanje kao i hraniva su smanjeni za oko 9,7%, dok je količina fosforne kiseline smanjena za 8,3%.
Abstract
Since agriculture is the highest consumer of water, there are many trials to improve water use efficiency especially in arid countries. Thus, in the world are developed many irrigation techniques that could decrease water use. In this paper is analyzed new irrigation technique (AutoAgronom) used in greenhouse cucumber (two varieties Rocky and Champion) production in order to improve water use in Israel. AutoAgronom is tested against conventional system where drip irrigation was used. AutoAgronom (AA) system follows pH, Electrical conductivity, oxygen level and nitrates on which basis irrigation was done. Obtained results strongly recommend use of AA system in vegetable production. In variety Champion irrigated by AA system (9.167 kg/m2 ) obtained yield was 20% higher in comparison with the same variety under conventional drip irrigation. Quantity of irrigation water, as well as fertilizers using AutoAgronom system are saved up to 9.7%, while phosphoric acid is saved up to 8.3%.
