“…The literature shows that the application of these inhibitors has considerably reduced inorganic N leaching, N 2 , NO and N 2 O emission while at the same time improving crop yield and N use efficiency [ 202 , 203 ] However, their effect on yield is very variable and depends on many factors. The application of fertilizer with urease inhibitors can increase the content of ammonium nitrogen in the soil by 10–59% compared to treatments without these inhibitors [ 204 ]. According to some researchers, it may increase the N resources in the soil and, consequently, gas losses of N (NH 3 , N 2 O) from the soil [ 205 ].…”

Fertilizer Use Efficiency (FUE) is a measure of the potential of an applied fertilizer to increase its impact on the uptake and utilization of nitrogen (N) present in the soil/plant system. The productivity of N depends on the supply of those nutrients in a well-defined stage of yield formation that are decisive for its uptake and utilization. Traditionally, plant nutritional status is evaluated by using chemical methods. However, nowadays, to correct fertilizer doses, the absorption and reflection of solar radiation is used. Fertilization efficiency can be increased not only by adjusting the fertilizer dose to the plant’s requirements, but also by removing all of the soil factors that constrain nutrient uptake and their transport from soil to root surface. Among them, soil compaction and pH are relatively easy to correct. The goal of new the formulas of N fertilizers is to increase the availability of N by synchronization of its release with the plant demand. The aim of non-nitrogenous fertilizers is to increase the availability of nutrients that control the effectiveness of N present in the soil/plant system. A wide range of actions is required to reduce the amount of N which can pollute ecosystems adjacent to fields.

“…The content of inorganic nitrogen was determined using the calorimetric method, the ammonia form of nitrogen using Nessler's reagent (Koch and McMeekin 1924), and nitrate nitrogen using phenol 2.4-disulfonic acid (Panáková et al 2016). The phosphorus and potassium contents were determined using the Mehlich III test (Mehlich 1984).…”

Maize (Zea mays L.) is considered one of the most important grains in nutrition and a notable bioenergetic crop (Bassu et al. 2014), although as reported by Perera and Weerasinghe (2014), the most significant part of production is used as feed for farm animals, part for human nutrition, various industrial processing, and export. Data from the Food and Agriculture Organisation (FAO) show that global maize production in 2020 was 1 162 million tons (FAO 2022). However, with the increasing trend of global climatic changes, it is expected that the grain yield and maize quality will decrease as a result of biotic and abiotic stresses (Sabagh et al. 2018). Among abiotic factors, drought is one of the most significant factors limiting field crop productivity (Hassan et al. 2016).

“…Prior to soil tillage, soil samples were collected (0.3 m) for laboratory analysis of the macronutrient content, soil pH, and humus content. The content of inorganic nitrogen was determined using the calorimetric method, the ammonia form of nitrogen using Nessler’s reagent [ 70 ], and nitrate nitrogen using phenol 2.4-disulfonic acid [ 71 ].

In this study, we focus on the mitigation of the negative impact of drought using the application of superabsorbent polymers (SAPs) to seed. One way to monitor drought and quantify its impact on crops in field conditions is the nondestructive measurement of physiological processes of the crops using spectral indexes LAI and PRI during vegetation. Therefore, during 2018 and 2019, the increase in biomass and intensity of photosynthetic activity was monitored, and the effect of the SAPs application on the yield parameters of the sugar beet was evaluated in the trial conditions (control, SAPs) at the end of the vegetation period. Through statistical analysis, the significant impact (α ≤ 0.01) of SAPs application on the values of spectral indexes LAI and PRI as well as root and white sugar yields was found. Although the sugar content difference between SAPs and control conditions was not statistically significant, SAPs had a positive influence on the value of this parameter. It was found through periodic monitoring of spectral indexes during the growing period that the crop in the SAPs condition showed higher values of PRI at the beginning of vegetation, which was caused by the accumulation of moisture in the vicinity of the seed and subsequent faster growth of roots and photosynthetic apparatus. Moreover, the values of LAI were significantly higher (α ≤ 0.01) in the SAPs condition throughout the vegetation period. In the interaction evaluation, we confirmed that in both years the values of LAI were higher in the condition with SAPs compared with the control. In contrast, the PRI values were significantly different across conditions. The interaction of conditions with variety showed that the variety Brian obtained higher values of LAI and PRI in the SAPs condition. The correlation analysis found a positive correlation between spectral indexes LAI:PRI (r = 0.6184**), and between LAI:RY (r = 0.6715**), LAI:WSY (r = 0.5760**), and PRI:RY (r = 0.5038*), which confirms the close relationship between physiological processes in the plant and the size of its yield.
