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/m 2 ) 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%.

Kadifica ( Tagetes patula L.) se ubraja u grupu jednogodisnjih cvjetnih kultura, a zbog svojih dekorativnih osobina posljednjih godina zauzima sve veci udio u proizvodnom asortimanu proizvođaca cvijeca u Bosni i Hercegovini.Sve veca potražnja za rasadom kadifice namece potrebu intenziviranja njene proizvodnje i podizanje njene kvalitete, a jedan od nacina kojim se to pokusava postici je primjena razlicitih stimulatora rasta. Cilj ovog rada je bio ispitati uticaj stimulatora rasta Bio-algeena S-92, Slavola i Ergonfilla na parametre rasta i razvoja kadifice ( Tagetes patula L.). Od parametara rasta i razvoja kadifice u ovom istraživanju ispitivani su: sadržaj pigmenta u listovima i povrsina listova, te precnik cvijeta i broj cvjetnih glavica po biljci. Rezultati istraživanja su pokazali da ni jedan od primijenjenih stimulatora rasta nije iskazao statisticki znacajan uticaj na povecanje estetski važnih parametara kvaliteta cvijeca: precnika cvijeta i broja cvjetnih glavica na biljci iz cega se može zakljuciti da kadifica nije zahtjevna kultura za uzgoj jer je u stanju uspjesno razviti svoje cvjetove cak i ako joj se u toku uzgoja ne dodaju stimulatori rasta. Preduslov za ostvarenje navedenog je da supstrat u kojem se kadifice uzgajaju svojim fizickim i hemijskim karakteristikama zadovoljava sve kriterije potrebne biljkama za njihov uspjesan rast i razvoj.
