Some prediction models indicate climate change will have a more pronounced impact on Hungary than previously anticipated. Traditionally, Hungarian agriculture is based on dryland farming, with irrigated farming practiced in a few areas. Land degradation is a significant concern. However, the loss of arable land due to water scarcity could be more widespread. One potential solution is to irrigate, which could maintain soil fertility for decades. Utilizing modern irrigation techniques is a crucial approach to making irrigation as sustainable as possible while ensuring yield and quality. This study aims to provide an authentic picture of irrigation in Hungary, past and present. It also aims to provide suggestions for the near future, drawing on examples from abroad.

In recent years, one of the major challenges for plant breeders has been the control of abiotic environmental stresses (drought, UV stress, salt concentration, water pressure). Increasingly variable and unpredictable weather anomalies are a warning of the detrimental effects they have on the growth of our crops and prevent us from reaching the potential of our genetic potential and nutrient supply. To prevent and reduce losses, the potential to protect plant health and increase plant resistance to stress must be anticipated and applied in the future if we are to be successful in agricultural production. One element of this is plant biostimulation. Today, crop producers use biostimulants as a compliance pressure, to obtain more subsidies (Agriecological Programme). Biostimulants applied inappropriately (mixed with herbicides), targeted, and at the right time, can have the opposite effect. This also induce irreversible processes in the crop plant. Although the winter swede rape area has been significantly reduced in our country, there are those who persevere despite the difficulties of growing it. Rapes can be successfully grown today with great care and intensive technology, and the weather conditions of recent years have consistently shown that environmental anomalies have a significant impact on its yield. In rapes, the use of biostimulators and fertilising products is considered common. Our studies with Quantis in rapes have clearly proven its effectiveness. In this article we would like to present the effect of biostiumulant (Quantis) on the production of rapes.

In countries such as Hungary, the utilisation of solar energy for irrigation represents a pivotal consideration. As a consequence of climate change, the crop rotation period is characterised by an increased availability of sunny and bright days. A paucity of cloud cover and precipitation has distinguished recent Hungarian summers. The necessity for adaptation in agriculture, which produces raw materials for food, will also arise as a result of the increasingly extreme weather conditions caused by global climate change. The irrigation of crops is a vital process during increasingly frequent periods of drought. However, the cost of irrigation can be expected to rise significantly in response to elevated energy prices. The objective of this research is to ascertain the viability of utilising irrigation systems powered by renewable energy sources. Hungary is on the verge of a significant investment in its national irrigation infrastructure. Nevertheless, the investment may prove to be unprofitable as a result of the expense associated with the energy required for irrigation. In three research areas, the energy production of the solar farms associated with the pivot irrigation system has been monitored, and the hyper-local evapotranspiration data has been calculated. Regression analysis was employed to evaluate the results. The findings indicate that the dataset is significant. The field results and analysis can be useful for upfront investment in such projects. Precipitation, as a third variable, has a positive impact on the relationship between energy production and crop water demand.

Winter rapeseed production has completely changed in Hungary in recent years. The use of hybrids has become commonplace, and intensive cultivation techniques are widespread. At the same time, average yields also increased, making rapeseed one of the most profitable crops. Maintaining profitability is a priority task, and in addition to further increasing average yields, improving quality parameters and crop safety is also decisive. Rapeseed production today faces significant challenges. As a result of climate change, the cultivation routine of decades is changing, and biostimulators are becoming more and more perspective in addition to foliar fertilisation with macro- and microelements. During this research, a 3-year small-plot field experiment was set up with a winter rapeseed indicator. The main objective of the experiment was to study the physiological reactions of rape plants to different doses of Zn and the combined reaction of the biostimulator and Zn. During the experiment, the reaction of the rapeseed test plant on zinc-deficient calcareous chernozem soils was investigated under the influence of different doses of Zn and combined doses of Zn and biostimulation. The aim of the study is to determine whether rapeseed plants respond to zinc supplementation and the combined effect of the bio stimulator and zinc with increased yield and improved nutritional values (protein content, oil content). In the first annual study, two treatments were performed, one in autumn (BBCH 16-18 phenological stage) and one in spring (BBCH 29 phenological stage). Zinc tetramine hydroxide was used in 4 different doses (2, 5, 10, 20 L/ha), zinc tetramine hydroxide enriched with copper in 2 different doses (5 and 10 L/ha), Quantis in the manufacturer's prescribed dose of 2 L/ha, biostimulant enriched with zinc, and a usual foliar fertiliser used in rapeseed growing with Wuxal boron at the dose recommended by the manufacturer. During the growing season, the development of root mass, root length, SPAD values, as well as the yield and oleic acid content were evaluated by mathematical statistical method. It can be stated that there was no significant difference in the root mass, root length, and SPAD values, but there was a significant yield difference in the amount of the crop in the second-year experiment (P = 10 %). Studies have shown that biostimulants have the greatest influence on the development of measured parameters.
