“…Kaplan et al [44] proved that the increased N level was an important factor, not just for GY, but also for starch and phytate accumulation in grain. In Serbia, maize is usually rotated with winter wheat, but a more prominent practice requires legume crops in the rotation in order to improve soil physical and chemical properties and to increase the maize yield and the protein content in grain [45]. Dobermann et al [19] conducted detailed N rate trials in 32 irrigated maize fields in southern Nebraska, USA, and pointed out that the economically optimal N rate for maize-following-maize rotations was 171 kg N ha −1 , giving GY of 14.9 t ha −1 , while, for maize-following-soybean rotations, this rate was 122 kg N ha −1 giving a yield of 14.5 t ha −1 .…”

A soil tillage system adjusted to the soil type and agro-ecological conditions, together with the optimal nutrient supply, is a prerequisite for high maize (Zea mays L.) yield. However, there is little knowledge about the influence of soil tillage and nitrogen (N) rates on maize grain quality. A study was initiated in 1978 in Zemun Polje, Belgrade, Serbia, on the chernozem soil type. The effects of three N rates—0, 180 and 240 kg N ha−1—within three tillage practices—no-tillage, reduced and conventional tillage—and their influence on grain yield (GY) and the content of proteins, starch, oil, total tocopherols and carotenoids, phytic phosphorus (Phy), glutathione (GSH), phenols and inorganic P (Pi) in maize grain were analysed in the period 2016–2018. Differences in maize GY were 2.57 and 3.01 t ha−1 for reduced- or no-tillage, respectively, in comparison to conventional tillage. Conventional tillage and higher N rates contributed to the increase in maize yield and the grain nutritional quality with regard to the increased level of proteins, GSH and Phy. On the other hand reduced inputs were beneficial only for grain quality, in relation to the increase in tocopherols and phenols.

“…The choice of crops and their allocation to plots is at the core of the farming system management (Negassa et al2015;Velychko, 2014). These decisions concentrate all the complexity involved in cropping system design and selection at the farm level because of their many involvements at different stages of the crop production processes (Simic et al 2016). The large number of possible adaptation options, model-based exploration tools are commonly used to supplement traditional empirical approaches (Schaller et al 2012;Han et al 2017) for designing and evaluating innovative agricultural production systems.…”

SUMMARYPreformed study approved for studied crops the dependency between crop nutrient uptake and concentration as well the impact of landscape positions, adaptation potential of species, varieties and hybrids occurrence. Perennial legumes (alfalfa, sainfoin) were more unpretentious. Pea varieties are moderately pretentious appeared to be better than cereal crops -megatrophs (barley, corn) in terms of edification for growing on slopes. The consumption of nutrients for the production of 1 ton of corn grain and relative quantity of byproducts was lower for the slope of the southern position than for the flat and the northern hill slope of the landscape position. The uneven appearance of the resource potential factors for eroded lands dictates the need for differentiated use of arable lands.

There is evident stagnation or decline in grain yield, as well as high variability in yields, depending on the environment in many countries in recent years, including Serbia and the Republic of Srpska. The causes of this variation were mainly due to the variation of the climatic factors, the onset of drought and the rise in temperatures. Expected changes and especially negative ones will most likely be reflected in the agriculture of southern Europe, especially the Mediterranean, and yield of main field crops. The most negative effects in the area of the continental climate will be in the Pannonian Region which includes Serbia, Croatia, Hungary, Bulgaria and Romania, R. Srpska as a part of Bosnia and Herzegovina. This area will be affected by more frequent waves of heat and drought, with no greater possibility of avoiding by shift of sowing time or other cropping measures. Based on a detailed analysis of climatic factors in the multy-annual period it can be emphasised that some changes in terms of temperature and precipitation occurred. The causes of drought mainly come from the atmosphere and affect our country and show clearly that the climate is changing in our area. Based on these facts, we must have the right answers in order to mitigate if not to completely eliminate these effects. Agronomic aspect of looking into the problem requires a good knowledge of our crop needs for primary vegetative factors as well as temperature and moisture. Annual air temperatures in the investigated period increased not only at the annual level, but also in the vegetative period of winter wheat and particularly maize. The temperature increase is particularly dangerous in the vegetative period of maize during the three months of June, July and August by almost 2 °C. Precipitations at a monthly level of the vegetative period or a total per year do not provide such a picture. Besides the lack in July, normally the warmest month, by and large, precipitations are somewhat higher than the reference 30-year period 1971-2000. This fact tells us that precipitations are more frequent in other parts of the year, which is more favourable for winter small grain cereals,at least when regarding warmer years (especially in the wet years as it is known in the case of extremely wet 2010 yr when it was vice versa). A man can hardly influence the quantity and distribution of rainfall, therefore his actions to combat drought are mainly of indirect character. This comprises a good knowledge of the problems and prediction. For this, we need a lot of knowledge of agronomy, genetics, ecology, physiology, and relevant technical and economic possibilities. If we start from the assumption that the main goal is to provide sufficient and safe quantities of food for our population, then we need to focus on what we have in our hands and begin with it. In the fight against drought, regular and specific cultivation practices are used along with an adequate assortment of crops with more tolerance to drought. Out of regular practices, soil tillage, particularly conservation tillage, proper fertilization, elimination of all possible mistakes in sowing should be taken into account as for optimal time and plant density. Care treatments are a useful tool which can eliminate the adverse effects and create favourable conditions for the growth and development of cultivated crops, ranging from the usual ones to some special ones that retain moisture and prevent moisture loss by encouraging its more efficient and economical use. Appropriately established crop rotations with greater diversification of crops provide better tolerance of extreme moisture, which is particularly the case of winter wheat. Our research shows inferiority of continuous cropping of both crops compared with different crop rotations. However, when comparing crop rotations with each other then it can be noticed that the proper setting, even under extreme conditions, provides better results. As for maize it is evident that all increases of moisture are suitable for it as it is related to the warmer part of the year, either as direct rainfall during the summer or indirectly if the reserve is provided from a period when there are more precipitations during the autumn, winter and spring. Moisture improves the efficiency of all other cultivation practices. In the case of its extended absence followed by high temperatures it is quite the opposite.
