“…In addition, N translocation from leaves to grains is high. Several studies conducted under NT systems in Brazil have shown an increase in N-leaf concentration of maize (Caires & Milla, 2016;Soratto, Silva, Cardoso, & Mendonça, 2011) and wheat (Los Galetto et al, 2017;Teixeira Filho, Buzetti, Andreotti, Arf, & Sá, 2011) with increasing N rate application. In grains, an increase in N concentration was also obtained with top dressing N fertilization compared to N application only at sowing of maize (Pedrosa et al, 2020) and with increasing N rate application in top dressing of wheat (Los Galetto et al, 2017;Rodrighero et al, 2015).…”

Seed inoculation with Azospirillum brasilense and nitrogen fertilization for no‐till cereal production

Cereal crops have a high N requirement in a high‐yield environment. However, N use efficiency is still low in agricultural production systems and little is known about the effects of inoculation with Azospirillum brasilense in a high‐yield environment. A field experiment was conducted from 2012 to 2018 with a maize (Zea mays L.)–wheat (Triticum aestivum L.) rotation under a continuous no‐till in southern Brazil. Seeds were inoculated with A. brasilense (strains Ab‐V5 and Ab‐V6) and different levels of N fertilization were used in top dressing. Seed inoculation provided slight changes in N, P, and K concentrations in leaves and grains of maize and wheat. Increasing N input increased the leaf and grain N concentration and the maize and wheat grain yields. Seed inoculation caused varied responses on cereals in different cropping seasons. Wheat was more affected by inoculation in response to N application than maize. Rainfall distribution during the growing seasons possibly interfered on crop responses with inoculation between years and N fertilization levels. Under a similar N input, inoculation resulted in an average increase of 454 kg ha−1 yr−1 of maize and 242 kg ha−1 yr−1 of wheat by applying a higher N rate to the maize and a lower N rate to the wheat. An additional gain of US$409.72 ha−1 (2012–2018) was also achieved using this strategy. Although the possibility of inoculation causing economy with N fertilization in wheat was evident, for maize in rotation with wheat, A. brasilense inoculation was apparently more viable under higher N fertilizer input.

“…However, the nutrient contents in corn grains used as reference values in Brazil have been practically the same for over 20 years (Raij et al 1996;Cantarella and Duarte, 2004), and are based on old studies, such as those of Andrade et al (1975a,b), Hiroce et al (1989), and Coelho and França (1995). The diversity of plant materials and heterogeneity of management types can influence grain nutrient contents (Carlone and Russel, 1987;Ciampitti and Vyn, 2013;Caires and Milla, 2016). Recent results of grain nutrient contents indicate a possible reduction in N and K (Resende et al, 2012), although the high variation among environments and/or cultivars hampers a joint interpretation that would enable conclusions about the new reference values.…”

Unchanged reference values of grain nutrient contents for corn have been used for over 20 years, despite yield increases, the development of new hybrids, and modifications to cropping systems, especially the establishment of in-season second crops and the wide adoption of no-tillage. This study measured macro-and micronutrient contents in corn grains from different regions, in the first (summer) and second (fall) crop, to update the reference values of estimated nutrient removal. A secondary objective was to determine whether there were correlations between grain nutrient contents and grain yields and densities. In this study, 175 corn grain samples of experiments on cultivar evaluation and 22 samples from soil management trials from five states (SP, PR, MG, MT, and MS) were used. Grain nutrient contents were ranked as follows: N > K > P > Mg > S (g kg-1) and Ca > Zn > Fe > Mn > B > Cu (mg kg-1). Content values for half of the nutrients analyzed were negatively correlated with yield and/or seed weight, whereas grain density was not correlated with nutrient contents. For the first crop of corn, the N, S, and Cu contents clearly decreased with increases in grain yield and seed weight, indicating a lower nutrient removal at higher yields. The great variability of results among environments makes it difficult to differentiate between the first and second crop of corn. The reference values currently in use overestimate the removal of N, P, K, Ca, Mg, S, and Zn grain contents, but underestimate Cu and B in corn. The results of this study can be used to update the reference values of nutrient contents of corn grains to better estimate nutrient removal from the soil.

“…Ear diameter, in turn, is often related to grain filling and to the number of grain rows per ear (Ohland et al, 2005). According to studies, the number of rows per ear is a component dependent on the plant's genetic potential and on environmental conditions (Valderrama et al, 2011;Caires & Milla, 2016). For this reason, there was no interaction between N sources and application times in this study.…”

Urea is the nitrogen fertilizer most used in agriculture and the most subject to N losses. Thus, it is important to look for alternatives to reduce these losses and increase agronomic N use efficiency. In this sense, this study evaluates the effect of split or single application of slow-release and conventional urea in maize development and yield, as well as the fertilizer use efficiency by plants. The experiment was carried out in Santa Rosa do Sul-SC, in a randomized complete block design with 5 treatments and 3 replicates. The treatments evaluated were: control; 100% of the recommended dose of conventional urea at sowing; 30% of the recommended dose of conventional urea at sowing and 70% at topdressing; 100% of the recommended dose of slow-release urea at sowing; 30% of the recommended dose of slow-release urea at sowing and 70% at topdressing. The variables analyzed were ear insertion height, stem diameter, leaf chlorophyll content (R1 stage), yield components, crop yield, and nitrogen use efficiency. The split application of slow-release urea to the soil positively affected stem diameter and nitrogen use efficiency in maize plants, being, therefore, a good fertilization alternative for the crop in the soil and climate conditions of the region.
