Abstract With the advance of the no-tillage system (NT system) in Brazil, the adoption of technologies for nitrogen fertilization in these soils become essential for increasing the efficiency of N use in the system. In this sense, the objective of this study was to quantify ammonia losses, N removal in grains, and with 2nd crop yield in NT system and conventional (T system) planting areas that received application of different N fertilizers and their technologies. Ammonia volatilization, N extraction in grains and corn yield in response to the application of conventional fertilizers were compared to urease inhibitors treated urea in NT and T systems. The treatments were: no-N (Control); Prilled urea (PU); urea + NBPT (UNBPT); urea + Cu + B (UCuB); ammonium nitrate (AN), and ammonium sulfate (AS). In the NT system, the N-NH3 losses were 49% greater than in the T system; without differences for corn yield. The fertilizers as AN, and AS had the lowest N-NH3 losses, regardless of tillage system. UNBPT reduced the mean N-NH3 loss by 33% compared to PU. UNBPT (1,200 mg kg-1) and UNBPT (180 mg kg-1) reduced by 72% and 22% the N-NH3 losses compared to PU in the NT system.

O experimento, conduzido entre 01/10/2019 a 10/02/2020, foi estabelecido em faixas, com parcelas subdivididas, quatro repetições e dois tratamentos (sistemas de cultivo e lâminas de irrigação). Nas parcelas, os sistemas de cultivo foram: semeadura convencional e semeadura direta. Nas subparcelas, as lâminas de irrigação (percentual da lâmina líquida - %IL) foram: 0, 30, 63, 100 e 193%. Após a colheita, a produtividade de espigas (com e sem palha) e de grãos na umidade de 20,5 e 13% foram avaliadas. Os resultados mostraram que: 1) o sistema de cultivo não influenciou na produtividade; 2) a produtividade respondeu de forma quadrática às lâminas de irrigação; 3) lâminas próximas a 100% da IL resultaram em produtividades máximas e; 4) a sensibilidade ao déficit hídrico promoveu decréscimos de 20,4% na produtividade. Quando o custo do milímetro de água for 10 vezes maior que o custo do quilograma do milho (umidade 13%), economicamente é mais viável produzir 7.957 kg ha-1 com 60% da IL do que alcançar a produtividade máxima (8.283 kg ha-1).   Palavras-chave: lâminas de irrigação, sistemas de cultivo, déficit hídrico.     Prado, G; Tinos, A.

Irrigated corn yield at the Arenito Caiuá region in Northwest of Paraná State, Brazil     2 ABSTRACT   This work was performed at Universidade Estadual de Maringá, in Cidade Gaúcha/PR city, Brazil, and aimed to evaluate the corn variety IPR-164 yield, in different tillage systems and irrigation depths. The experiment, carried out from 10/01/2019 to 10/02/2020, was set in strips design, with subdivided plots, four replications, and two treatments (tillage systems and irrigation depths). In the plots, the tillage systems were: conventional-tillage and no-tillage. In the subplots, the irrigation depths (percentage of the net irrigation depth - %NID), were: 0, 30, 63, 100, and 193%. After harvesting, the data corn ear yield (in-husk and unhusked) and the grain yield with the moisture of 20.5 and 13% were evaluated. The results showed that: 1) the tillage system did not influence the corn yield; 2) corn yield presented a quadratic response to the irrigation depths; 3) irrigation depths close to 100% of NID provided maximum yield; 4) the sensitivity to water deficit led to a 20.4% decrease in corn yield. When the millimeter water cost is 10 times greater than the corn kilogram cost (moisture 13%), it is economically more profitable to produce 7,957 kg ha-1 with 60% of NID than to reach  the maximum yield (8,283 kg ha-1).   Keywords: irrigation depths, tillage systems, water deficit.

The objective of this study was to evaluate changes in the chemical attributes of the soil caused by the use of limestone associated or not to with gypsum in no-tillage system. The experiment was conducted on a dystrophic Yellow Latosol in Pará state, Brazil. The experimental design was in randomized blocks in split plots with three replications. The treatments consisted of five doses of limestone (0, 1, 2, 3 and 4 t ha-1), with and without gypsum (0, 0.5 and 1 t ha-1). Soil samples were collected at depths of 0-20 and 20-40 cm. There was a significant effect on the analyzed variables at both depths. The doses of 3.64 and 2.19 t ha-1 of limestone associated with 0.5 t ha-1 of gypsum, were responsible for the largest increase in soil calcium content in the 0-20 and 20-40 cm layers, respectively. The highest increase in Ca + Mg content was found at 3.63 t ha-1 limestone combined with 0.5 t ha-1 gypsum. It was observed that 3.13 t ha-1 of limestone combined with 0.5 t of gypsum increased soil CEC. The 2.89 t ha-1 dose of limestone combined with 0.5 t of gypsum contributed to the increase in base saturation (V%). The use of limestone and gypsum promotes soil chemical conditions, as reflected by increased corn yield when compared with control (no treatment) plots.

Efficient water management in agriculture is an important part of the general programme on water resources preservation. This study is devoted to the determination of the effects of soil processing system and mineral fertilization on the water use efficiency and productivity of grain corn (Zea mays Linnaeus, 1753). The trials were conducted in 2017–2018 on irrigated land in the South of Ukraine. The field experiments were carried out on the experimental plots of the Institute of Irrigated Agriculture of the NAAS in four replications. We studied the following agrotechnological parameters and their combinations: Factor A – primary tillage type and depth within different tillage systems in the short crop rotation (grain corn – grain sorghum – winter wheat – soybean); Factor B – application rates of mineral fertilizers (N0P0, N120P60, N180P60). We established that the highest yield of grain accompanied by the best water use efficiency was provided by the cultivation technology with disk cultivator tillage on the depth of 8–10 cm within the differentiated tillage system in the crop rotation under the maximum nutritive background of N180P60. This agrotechnological variant resulted in a corn grain yield of 14.51 and 14.59 t/ha in 2017 and 2018 years of the study, respectively. The coefficient of water use efficiency, which is the relation of the water used by the crop to the yield, in this variant was the lowest – 39.6 and 42.0 mm/t in 2017 and 2018, respectively, which indicates the optimum response of corn grain to watering. The worst indexes of water use efficiency and corn productivity were determined in the experimental variant with disk cultivator tillage on the depth of 12–14 cm within the subsoil tillage system within the crop rotation under non-fertilized conditions. We determined that strengthening of the crop nutrition under the rational tillage system in crop rotation is helpful in optimization of the crop water use in the irrigated conditions of the South of Ukraine, which is very important in the current conditions of freshwater scarcity.

Tillage System

Tillage system is one of the factors that influences crop yield. The aim of the research was to determine the influence of the basic tillage systems on the change in soil fertility, yield and quality of corn grain in the soil and climatic conditions of the central zone of the Krasnodar Territory. The surveys were conducted in 2018–2020 on the experimental fields of the FSBSO “National Center of Grain named after P. P. Lukyanenko”. Soil – chernozems leached. All the experiments were carried out according to the standard methodology. In a stationary experiment, observations were performed to study several tillage practices: conventional tillage (25 cm depth plowing), mulch tillage with soil decompaction (reduced tillage done with a chisel plow to a depth of 32 cm for row crops), mulch tillage (deep tillage is excluded, disking to a depth of 10 cm twice or thrice is used instead). Plowing to a 25 cm depth improves the bulk of the soil in the 0–30 cm layer. However, chiseling to a depth of 32 cm and disking to a depth of 10 cm twice or thrice caused soil compaction. Standard tillage practice led to a decrease in the number of agronomically valuable aggregates (61.1 %) and their water resistance (59.4 %) compared to soil decompaction and minimum-tillage systems. The highest rates of productive moisture reserves were on the plots with traditional tillage and decompaction (140.6 and 141.5 mm, respectively, which is 14.7 % higher compared to the minimum mulching). The studied soil cultivation systems did not affect “1000-grain weight” but significantly affected the yield of grain from one ear (124.3 g) and the number of formed ears per one plant (1.04 pcs.). The corn yield on the fields with traditional and decompaction tillage methods was 56.9 and 55.9 c/ha, respectively; on minimum-tillage system, it decreased by 4.8 %. Protein content in grain harvested from the plots with traditional tillage practice was 11.4 %, which is higher compared to the minimum-tillage system. No significant differences were detected for crude ash and dry matter.

The objective of this work was to evaluate the efficiency of nitrogen fertilization in relation to the population of corn plants in a yellow latosol under no-tillage system. The experimental design was a randomized block with three replications, in a 4 x 4 factorial scheme, corresponding to four levels of N (0, 60, kg haˉ¹ 120 and 180) and four planting densities (45,000; 55,000; 65,000 and 75,000 plants haˉ¹). 48 soil samples were collected to determine chemical soil attributes (pH, OM, K, Ca, Na, Mg and Al) and 48 leaf samples to determine macronutrients in the leaf (N, P, K, Na, Ca and Mg). The data were submitted to comparison of means by the Scott-Knott test. The corn yield increased linearly up to the dose of 180 kg haˉ¹ N. Higher productivity was observed with the combination of 120 and 180 N (kg haˉ¹) with the density of 75,000 plants ha-1. There was an increase in the N content in the leaves with increasing doses of N in the soil

Field experiments were conducted over 3 yr at two locations in northwest Kansas to evaluate the efficacy and crop tolerance of EXP 31130A alone and with other herbicides in corn. EXP 31130A alone and in combination with acetochlor, atrazine, or metolachlor controlled kochia and redroot pigweed 93% or greater regardless of location, year, or tillage system. Green foxtail control in 1997 and 1998 was > 90% with EXP 31130A in combination with chloroacetamide herbicides but varied among experiments with EXP 31130A alone. Control of puncturevine with EXP 31130A alone or in tank mixtures was 75% or greater at five of six sites. EXP 31130A alone and in combinations caused minor, early-season, corn leaf bleaching and/or stunting under conventional tillage. However, no injury was detected in no-till systems. In 1996, no-till corn receiving EXP 31130A treatments yielded similarly or up to 29% more than hand-weeded corn. Yields did not differ among treated, untreated, and hand-weeded corn in 1996 under conventional tillage, where weed interference was not as intense as under no-till conditions. Conventional-tillage corn receiving EXP 31130A alone or in tank mixtures in 1997 yielded similarly to hand-weeded corn. Averaged over experiments, corn yield in 1998 increased by 10 to 18% with applications of EXP 31130A alone or in combinations compared to untreated corn.
