The occurrence of late spring frosts due to climate change causes great damage plantation production worldwide. main objective the paper is provide a comprehensive overview problem and outline effective protective measures against frosts. nature frost depends on regional, altitudinal, geographic differences, but they all share common problem: remove heat, resulting in freezing new plant growth flowers. Tissue affected by critical temperatures type, intensity, duration. Protection can be...
Irrigation efficiency improvement requires optimization of its parameters like irrigation scheduling, threshold and amount water usage. If these are not satisfactorily optimized, negative consequences for the plant-soil system can occur with decreased yield hence economic viability agricultural production. Numerical modelling represents an efficient, i.e. simple fast method optimizing testing different scenarios. In this study HYDRUS-1D model assuming single- dual-porosity systems was used...
Considering the demand for optimization of technical factors spraying a greater area coverage and minimal drift, field tests were carried out to determine interaction between coverage, number droplets per cm2, droplet diameter, drift. The studies conducted with two different types sprayers (axial radial fan) in an apple orchard vineyard. interactions nozzle type (ISO code 015, 02, 03), working speed (6 8 km h−1), norm (250–400 L h−1). airflow both was adjusted plantation leaf mass pressure...
This study was conducted (2010–2012) to analyse the efficiency of irrigation scheduling in maize production based on soil moisture measurements (Watermark sensors) years with extreme weather events at research site Agricultural Institute Osijek, eastern Croatia. Three treatments and four hybrids were studied. In extremely rainy 2010, highest yield grain obtained rainfed plots (control = 9.24 t ha−1). A significantly (P < 0.01) lower (−8%) fully irrigated (a3 8.59 opposite results from...
SAŽETAK Plastičnost je tla područje konzistencije tla, odnosno predstavlja promjenu stanja zbog različite vlažnosti
This study employed an ensemble machine learning approach to evaluate the effect of bioclimatic covariates on prediction accuracy soil total carbon (TC) in Pannonian biogeoregion. The analysis involved two main segments: (1) evaluation base environmental covariates, including surface reflectance, phenology, and derived compared addition covariates; (2) assessment three individual methods, random forest (RF), extreme gradient boosting (XGB), support vector (SVM), as well their for TC...
U radu su prikazani rezultati istraživanja razlika u sklopu i prinosa zrna kukuruza primjenom dva sustava sjetve: standardna sjetva trake, tj. udvojene redove (engl. twin row). Za standardnu sjetvu koristila se OLT PSK 4 sijačica, a za trake sijačica MaterMacc Twin Row 2. Istraživanje je obavljeno na pokušalištu Poljoprivrednog fakulteta Osijeku, nedaleko od mjesta Klisa, tijekom 2017. godine, koja karakterizirana kao sušna godina (manje količine oborina više prosječne temperature...
U radu su prikazani rezultati prinosa zrna (kg ha-1) pri standardnoj sjetvi hibrida kukuruza i u udvojene redove/sjetva trake (engl. twin row sowing). Istraživanja provedena od 2016. do 2018. godine na pokušalištu Fakulteta agrobiotehničkih znanosti, pokraj mjesta Tenja (45°31’1,83” s. z. š.; 18°46›37,5» i. d.). Na standardni sustav sjetve s razmakom redova 70 cm sjetvom redove 22 posijani hibridi FAO grupa dozrijevanja: H1 = 290, H2 380, H3 410, H4 450 H5 590. hibrid ostvario je prosječni...

The research results of the spraying technical factors' impact on ground and air drift, deposit treetop in cherry orchards, are presented paper.Two different systems (classical sensory system) investigated, Agromehanika AGP 200 ENU sprayer being used.The is conducted according to ISO standard 22866 (Plant Protection Equipment -Drift Measurement Methods Field Conditions).The norm as factor A (A1 -250 l/ha; A2 -200 l/ha); nozzle type B (B1 -Lechler TR 8002 C; B2 ITR C) fan velocity C (C1 -18...
This paper represents the results of research generated noise levels measured in three different years (2010, 2013, and 2015), accordance with proscribed norms HRN ISO 6394, 6396 5131.The was conducted on test sites Belje d.d.company.The measurement carried out tractors FENDT model 410 aim determining increase relative to time spent exploitation.The obtained showed that none produced a higher level than permitted 90 dB.The main hypothesis this experiment is that, exploitation-wise, greater...
Preliminary communicationMany filtration systems employing perlite granulations have been designed so far.Size distribution of particles directly influences the retention properties filter media.The information on size particles, used in each specific dead-end process (the flow fluid being filtered is perpendicular to surface medium), crucial for adequate design medium.In order facilitate possessing media this kind, a new and particular mathematical model has developed present study.It based...
U radu je prikazan utjecaj dvaju različitih sustava raspršivanja (klasičnoga i senzorskog) pomoću raspršivača Tifone Vento 1500, s različito podešenim tehničkim čimbenicima raspršivanja, na zemljišno zračno zanošenje tekućine te depozit u krošnji. Istraživanje obavljeno prema ISO normi 22866:2005 nasadu višnje. Analizom varijance ispitan norme kao čimbenik A (A1 - 250 l ha-1; A2 200 ha-1), tip mlaznica B (B1 Lechler TR 8002C; B2 ITR 8002C) brzina zračne struje ventilatora C (C1 18 m s-1; C2...
