The modern development of recent years has not left agriculture untouched either. The advent and introduction of precision technology have accelerated events further. Slowly, even the smallest farms are trying to move from the methods they have become accustomed to as much as possible, using precision technology to make their operations more efficient and profitable, as those who lag behind will lag behind and will not be sufficiently competitive with other producers. Precision development covers all areas, we have the opportunity to apply new knowledge and technologies in sowing, irrigation, plant protection, harvesting, and last but not least, nutrient replenishment and even other areas. This development is a major task and very topical for smaller producers in rural areas, as they need to develop and create the necessary financial resources, which in many cases can only be achieved in the form of subsidies from different locations. This is all the more true for horticultural crops, since, for example, in contrast to the arable crop production, producers have much higher energy and capital requirements to achieve the same level of profit. In the course of the study, we examined the opinion of the producers supported by the Southern Horticultural Cooperatives – Délalföldi Kertészek Szövetkezete (DélKerTÉSZ) - whether the Agro Sense decision support precision tool placed to them had improved their production conditions and made their production more profitable due to the use of the tool.

The influence of different fertilizer doses on the yield and quality of winter wheat was studied on meadow soil in the crop-year 2016-2017 in Hódmezővásárhely. The experiment was set up on the area of the SZTE Tangazdaság Ltd, in three replications. The forecrop was sunflower. Six fertilizer setups were applied besides the control: N80PK30, N100PK30, N130PK30, N150PK30, N170PK0, and N170PK50 kg/ha active ingredients. The year 2016-2017 was unfavourable for winter wheat production. The amount of precipitation in the vegetative period of winter wheat was lower than the average. The obtained data were processed by single factor ANOVA. In the control treatment, the yield was 4.20 t/ha. The maximum yield of 5.60 t/ha was reached with N130PK30 kg/ha fertilizer treatment. The yield difference between the two treatments was statistically justified. The nutrient doses higher than N130PK30 did not increase the yield of wheat. A crude protein content of 17.60% was measured in the N0PK0 treatment. The highest content of crude protein (18.70%) was in the N100PK30 and N130PK30 treatments. The Zeleny number was 70.40 ml in the control treatment. In the N130PK30 treatment, it reached the maximum value of 76.0 ml. In our experiment, the N130PK30 kg/ha fertilizer dose was the most favourable concerning the yield and quality parameters of the examined winter wheat variety.
