Sustainable and profitable crop production has become a challenge due to frequent weather extremes, where unstable crop yields are often followed by the negative impacts of agronomic practices on the environment, i.e., nitrate leaching in irrigated and nitrogen (N)-fertilized crop production. To study this issue, a three-year field study was conducted during quite different growing seasons in terms of weather conditions, i.e., extremely wet, extremely dry, and average years. Over three consecutive years, the irrigation and N fertilizers rates were tested for their effect on grain yield and composition, i.e., protein, starch, and oil content of the maize hybrids; soil N level (%); and nitrate leaching. The results showed that the impact of the tested factors and their significance was year- or weather-condition-dependent. The grain yield result stood out during the extremely wet year, where the irrigation rate reduced the grain yield by 7.6% due to the stress caused by the excessive amount of water. In the remainder of the study, the irrigation rate expectedly increased the grain yield by 13.9% (a2) and 20.8% (a3) in the extremely dry year and 22.7% (a2) and 39.5% (a3) during the average year. Regardless of the weather conditions, the N fertilizer rate increased the grain yield and protein content. The soil N level showed a typical pattern, where the maximum levels were at the beginning of the study period and were higher as the N fertilizer rate was increased. Significant variations in the soil N level were found between weather conditions (r = −0.719) and N fertilizer rate (r = 0.401). Nitrate leaching losses were expectedly found for irrigation and N fertilizer treatments with the highest rates (a3b3 = 79.8 mg NO3− L).

Watermark, Tensiometer and Time Domain Reflectometry (TDR) are commonly used soil water sensors in irrigation practice whose performance depends on soil type, depth and growing conditions. Here, the results of sensor performance evaluation in different soil depths as well as the field and laboratory testing in silty clay loamy soil are presented. Gravimetric soil moisture samples were taken from sensor installation depths (10, 20, 30 and 45 cm) and used as reference Soil Water Content (SWC). The measurements varied significantly (p < 0.05) across the monitoring depths. On average across the soil depths, there was a strong negative linear relationship between Watermark (r = −0.91) and TDR (r = 0.94), and a moderate negative (r = −0.75) linear relationship between SWC and Tensiometer. In general, Watermark and Tensiometer measured SWC with great accuracy in the range of readily available water, generated larger Mean Difference (MD) than TDR and overestimated SWC, while TDR underestimated SWC. Overall, laboratory testing reduced the root mean square error (RMSE, Watermark = 1.2, Tensiometer = 2.6, TDR = 1.9) and Mean Average Error (MAE, Watermark = 0.9, Tensiometer = 2.04. TDR = 1.04) for all tested sensors.

The incidence rate of inflammatory bowel disease (IBD) is becoming a global health problem that could be caused by changes in environmental and lifestyle habits. The study aimed to identify the association between the quality of drinking water, i.e., physiochemical and biological aspects of the phenotype and activity of IBD in Eastern Croatia. The study included 312 patients (63.4% ulcerative colitis, UC, and 36.6% Crohn’s disease, CD) from the area of Eastern Croatia. The data were collected by questionnaires and the analysis of the water safety, based on 65 samples of drinking water by the patient’s water supply method (public supply, rural water supply, and private well). IBD was active in 38.0% patients (34.0% CD and 40.0% UC). Significant differences (p = 0.001) were observed in the distribution of patients, according to counties in which they lived in. The largest deviation was noted in coliform bacteria, Escherichia coli, and enterococci bacteria, Fe, Al, and nitrate in rural water supply and private wells, although, without significant impact on IBD phenotype and activity. The hazard quotient (HQ) simulations showed that children are a sensitive group, regarding exposure to nitrates in drinking water over a long period of time, so there is a need for further monitoring and analysis of this issue.

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 i zračno zanošenje tekućine te depozit u krošnji. Istraživanje je obavljeno prema ISO normi 22866:2005 u nasadu višnje. Analizom varijance ispitan je utjecaj norme raspršivanja kao čimbenik A (A1 - 250 l ha-1; A2 - 200 l ha-1), tip mlaznica kao čimbenik B (B1 - Lechler TR 8002C; B2 - Lechler ITR 8002C) i brzina zračne struje ventilatora kao čimbenik C (C1 - 18 m s-1; C2 - 12 m s-1). Raspršivanje je obavljeno sa 4-postotnom otopinom organske boje Tartrazine, a filter-papirićima je prikupljena zanesena tekućina. Optimalizacijom tehničkih čimbenika raspršivanja ostvaruje se maksimalno smanjenje od 36,59% za zemljišno zanošenje te 75,05% za zračno zanošenje na 5 m udaljenosti od tretiranoga reda. Eksploatacijom ultrazvučnoga senzorskog sustava za selektivnu aplikaciju zemljišno zanošenje smanjuje se za 43,35%. U ovome slučaju zračno zanošenje na 5 m udaljenosti od tretiranoga reda smanjuje se za 66,57% te 79,61% na udaljenosti od 10 m. Maksimalno reduciranje zračnoga zanošenja na 10 m ostvareno je uporabom ITR mlaznica analizirajući oba sustava raspršivanja. Eksploatacija ultrazvučnoga senzorskog sustava nije negativno utjecala na depozit u krošnji jer iz dobivenih rezultata nije zabilježena značajna razlika između dvaju sustava raspršivanja (0,5%). Opremanje konvencionalnih raspršivača naprednim sustavima za selektivnu aplikaciju značajno doprinosi preciznosti nanošenja sredstva za zaštitu bilja, a time i smanjenju negativnoga utjecaja na okoliš.

During the 3-year study, maize (Zea mays L.) production in the eastern Republic of Croatia suffered great losses due to periods of flood (2010) and drought (2011 and 2012). An excessive amount of water as well as lack of it caused variation of yield and efficiency of irrigation scheduling. Irrigation treatments included a rainfed treatment and irrigation up to soil water content 80–100% of field capacity. The nitrogen fertilization treatments were 0 (control) and 200 kg N ha−1. The analysed crop productivity parameters were 1000-grain mass and grain yield, in two hybrids. The irrigation significantly increased maize grain yield in dry years, while in the extremely wet year of 2010 yield in the irrigated plot was reduced doe to stress caused by excessive rainfall and over-irrigation. Both tested hybrids responded positively to the combination of nitrogen fertilizer and irrigation. Regardless of whether expressed on a fresh tissue or dry weight basis, the proline content in maize leaf did not show a clear effect of irrigation treatment, whereas nitrogen fertilization stimulated this amino acid accumulation. There was a close relationship established between proline in leaf dry matter in both growth stages and 1000-grain mass, as well as a weak relationship between this parameter at flowering and final grain yield.

Au cours d'une étude de 3 ans dans l'est de de la République de Croatie, le maïs (Zea mays L.) a subi de grandes pertes dues à des périodes d'inondations (2010) et de sécheresses (2011 et 2012). Une quantité excessive d'eau ainsi que son insuffisance ont provoqué des variations du rendement de la culture et de l'efficacité de la planification de l'irrigation. Les traitements d'irrigation prennent en compte les apports pluviaux jusqu'à amener le sol à une teneur en eau de 80 à 100% de la capacité au champ. Les traitements de fertilisation azotée étaient de 0 (témoin) et 200 kg N ha−1. Les paramètres de la productivité des cultures analysées étaient le rendement global et le poids de 1000 grains, et ceci pour deux hybrides. L'irrigation a augmenté de manière significative le rendement en grains de maïs dans les années sèches, tandis que dans le rendement en période extrêmement humide (2010) a été réduit pour cause de précipitations excessives et de surirrigation. Les deux hybrides testés ont répondu positivement à la combinaison d'engrais azotés et de l'irrigation. Peu importe si elle est exprimée en proportion de la masse de tissus frais ou en poids sec, la teneur en proline dans le maïs feuille n'a pas montré d'effet clair du traitement de l'irrigation. Alors que la fertilisation azotée a stimulé l'accumulation de cet acide aminé. Il y avait une relation étroite établie entre la teneur en proline et la masse de feuilles vertes aux deux stades de croissance et, aussi, le poids des 1000 grains; par contre, cette corrélation est faible entre la valeur de ce paramètre à la floraison et le rendement en grain total.

The western corn rootworm (Diabrotica virgifera virgifera LeConte; WCR) is a serious maize pest in Croatia. The species was first registered in Europe in the early 1990s and since then became one of the most dangerous maize pests, especially in parts of Central and Southeast Europe. Larvae that feed on the maize roots cause the most serious damages in maize fields. Management of this pest is difficult and expensive, with possible serious impact on the environment. Native (or host-plant) resistance of maize against WCR could provide new economically and ecologically sustainable options in WCR management. Main goal of this study was to assess the variability of maize germplasm, correlations among resistance traits, and detect potential sources of resistance that could be used in breeding programs in order to develop hybrids with higher level of resistance against WCR. To our knowledge, the first native resistant hybrid is yet to be registered. Results showed great variability of estimated germplasm. Effect of the genotype was significant in all environments, as well as many interactions between genotype and the environment. Significant interactions emphasize the importance of the environment in WCR native resistance research. Significant positive correlations among all traits were detected. Several inbred lines were selected as a potentially useful germplasm for resistance breeding programs.

This study was conducted (2010–2012) to analyse the efficiency of irrigation scheduling in maize production based on soil moisture measurements (Watermark soil moisture sensors) in years with extreme weather events at the research site of the Agricultural Institute in Osijek, eastern Croatia. Three irrigation treatments and four maize hybrids were studied. In the extremely rainy 2010, the highest yield of maize grain was obtained in rainfed plots (control = 9.24 t ha−1). A significantly (P < 0.01) lower yield (−8%) was obtained in fully irrigated plots (a3 = 8.59 t ha−1). This was opposite to the results obtained from the extremely warm 2011 and very dry 2012, when grain yield was higher as the amount of irrigation water was increased. Maize grain yield in the fully irrigated plot was 25% (2011) and 40% (2012) higher compared with the control plots (dryland). According to our results, the main factor for irrigation efficiency in extreme weather conditions is to properly determine the optimum level for soil moisture sensors and ground water level in relation to root depth.

Four inbred lines of maize (Os 438-95 = C1, Os 30-8 = C2, Os 6 = C3 and Os 1-44 =C4) were grown for 4-year period (2006-2009) in the stationary field experiment on Osijek eutric cambisol. Impact of irrigation, nitrogen fertilization and genotype were tested. Soil moisture was maintained by two irrigation rates from 60-100% and 80-100% of the field water capacity). Two steps of N (0, 100 and 200 kg N ha-1) were applied, while P and K fertilization was equal (500 kg/ha NPK 0:30:20). Eight maize genotypes (four inbred lines and four hybrids) were grown on each basic plot of fertilization. The experiment was duplicated for maize - soybean rotation. The experiment was set by split-split plot method according to randomized block design in three replicates. The basic plot areas were 617.2 m2 (irrigation), 313.6 m2 (fertilization) and 39.2 m2 (genotype). Selection of N non-fertilized treatment and four inbred lines were made for this study with aim of testing year (A) irrigation (B) and genotype (C) effects under natural N-soil conditions. Average grain yield in level 1809 kg ha-1without N fertilization is indication of very high fertility of the soil. Differences of yield among the years were from 823 (2007) to 2450 (2006) kg ha-1. Excessive drought and high air-temperature stress is responsible for the low maize yield in 2007. Irrigation considerable affected on maize yields (4-year averages: 1500, 1809 and 2118 kg ha-1, for B1, B2 and B3, respectively). Differences of the 4-year average yields among the genotypes were from 1259 (C3) to 2765 (C1) kg ha-1. Differences of yield among the genotypes in the different years were also considerable because the lowest yield was for 71% (A1), 23% (A2), 63% (A3) and 40% (A4) lower in comparison to the highest yield. The genotype effects under different water supplies were less influencing factor because the high-yielding C1 had for 128%, 129% and 106% the higher yield compared to the low-yielding C3, for B1, B2 and B3, respectively. Differences of grain -protein, -starch and -oil among the years was from 9.61 to 11.84%, from 68.51% to 70.93% and from 3.50% to 4.17%, respectively. The C2 separated by the higher grain protein contents (10.93%) from the remaining three genotypes (average 9.96%). The genotype effects on starch and oil contents were from 69.83% (C4) to 70.58% (C1) and from 3.56% (C3) to 4.09% (C1), respectively.

In the decade from 2000 to 2009, the yield of maize grain in Croatia varied from 4.2 t ha−1 (2003) to 8.0 t ha−1 (2008). The yield variation was mainly caused by weather conditions unfavourable for maize production, meaning lack of precipitation, unevenly distributed during the vegetation season, and mean air temperatures above the long-term mean. Irrigation has become a justified and essential agrotechnical measure that minimizes the damage caused by water deficit during critical plant growth stages and ensures high yields with good quality. In this paper two vegetation seasons (2006 and 2007) with quite different weather conditions for maize production were analysed in order to examine the importance of irrigation in terms of yield increase, irrigation water use efficiency (IWUE), irrigation efficiency (IE) and irrigation water use index (IWUI) in years favourable (2006) or too dry (2007) for maize production. The yield surpluses achieved with irrigation ranged from 8.54 t ha−1 to 9.62 t ha−1 in the average crop year (2006) and from 8.43 t ha−1 to 10.7 t ha−1 in the dry year (2007), depending on the irrigation method. In the dry year the values of IWUE where higher than in the average year (6.16 and 13.75 kg ha−1/mm, respectively, averaged over the hybrids).
