Nitrogen Fertilization of Wheat Double‐Cropped Following Grain Sorghum in a No‐Tillage System

ABSTRACT The no-tillage system can change the nitrogen dynamics in the soil, being necessary to adjust the nitrogen fertilization in order to provide this nutrient during critical phases of the common bean growth. This study aimed at evaluating the agronomic and qualitative traits of common bean grown under different straw types, as a function of the topdressing nitrogen fertilization splitting. A randomized block experimental design, in a split-plot arrangement, with four replications, was used. The plots consisted of three straw types (maize, maize intercropped with brachiaria and brachiaria), while the subplots comprised the combination of these straw materials with 8 topdressing nitrogen fertilization splitting arrangements. The common bean on brachiaria straw shows higher grain yields and crude protein contents. The nitrogen fertilization splitting, as topdressing, interacts with the straw types, increasing the number of pods per plant. The common bean plants growing on plots with single-maize straw had a shorter time for maximum hydration. The topdressing nitrogen fertilization splitting has no effect on the common bean qualitative traits.

RESUMO – A resposta à adubação nitrogenada da cultura do milho é dependente do tipo de solo, sistema de cultivo, dose empregada e cultura antecessora. Nesse contexto, objetivou-se com o presente trabalho avaliar os efeitos dos resíduos vegetais de plantas de cobertura e da adubação nitrogenada no milho cultivado em sequência, sob sistema de plantio direto em consolidação no Cerrado. O experimento foi constituído de um fatorial 10 x 4, em delineamento de blocos casualizados e esquema de parcelas subdivididas, com quatro repetições. Os tratamentos das parcelas foram os resíduos do cultivo de dez plantas de cobertura (Cajanus cajan, Canavalia ensiformis, Crambe abyssinica, Crotalaria juncea, Crotalaria ochroleuca, Crotalaria spectabilis, Mucuna aterrima, Pennisetum glaucum, Raphanus sativus e Urochloa ruziziensis) e, nas subparcelas, foram testadas quatro doses de nitrogênio (0, 50, 100 e 150 kg ha-1 de N) em cobertura no estádio V5 da cultura do milho. Observou-se baixa resposta à adubação nitrogenada em cobertura, o que foi atribuído principalmente à ocorrência de déficit hídrico nas fases de florescimento e enchimento de grãos. De modo geral, as características agronômicas do milho foram mais influenciadas pela adubação nitrogenada do que pelas plantas de cobertura cultivadas anteriormente. O ganho médio de produtividade de grãos foi da ordem de 3,7 kg para cada 1 kg de N aplicado. O milho após Urochloa ruziziensis e Crambe abyssinica apresenta menor produtividade em relação ao uso das outras espécies de plantas de cobertura, independentemente da adubação nitrogenada.Palavras-chave: adubação verde, sistema conservacionista, veranico, Zea mays.COVER CROPS AND NITROGEN FERTILIZATION ON MAIZE GROWN IN NO-TILLAGE SYSTEM UNDER WATER DEFICIT ON CERRADO SOILABSTRACT - The response to nitrogen fertilization of the corn is dependent on the type of soil, cropping system, dose used and preceding crop. In this context, the goal of the present study was to evaluate the effects of cover crops residues and nitrogen fertilization on corn grown in succession, under no-tillage system in the Cerrado region. The experiment was arranged in a factorial 10 x 4, in a randomized complete block design and subdivided plot scheme, with four replications. The treatments of the plots were the residues of ten cover crops (Cajanus cajan, Canavalia ensiformis, Crambe abyssinica, Crotalaria juncea, Crotalaria ochroleuca, Crotalaria spectabilis, Mucuna aterrima, Pennisetum glaucum, Raphanus sativus and Urochloa ruziziensis) and in the subplots four nitrogen doses (0, 50, 100 and 150 kg ha-1 of N) were tested in the V5 stage of the corn. A low response to nitrogen fertilization was observed, which was mainly attributed to the occurrence of water deficit at the flowering and grain filling stages. In general, the agronomic characteristics of corn were more influenced by nitrogen fertilization than by the cover crops previously cultivated. The average gain of grain yield was of the order of 3.7 kg for each 1 kg ha-1 of N applied. Corn after Urochloa ruziziensis and Crambe abyssinica presented lower productivity compared to the use of other cover crop species, regardless nitrogen fertilization.Keywords: green manure, conservation tillage system, summer water deficit, Zea mays.

Tillage System

Unsustainable cultivation techniques can cause carbon loss on farm. The cultivation technique that is often used by farmers today is intensive tillage. Intensive tillage can increase CO2. Steps to reduce CO2 gas emissions, while increasing carbon stored in the soil by implementing agricultural cultivation with conservation tillage system (Olah Tanah Konservasi). The conservation tillage system is able to reduce global warming through absorption of C in the soil, and reduce CO2 emissions. In addition, fertilization can also affect CO2 emissions. CO2 emissions in the soil come from soil respiration. The purpose of this study was to determine the effect of long-term tillage systems on soil respiration, determine the effect of long-term N fertilization on soil respiration, and determine the effect of interactions between tillage systems and long-term N fertilization on soil respiration. The study was arranged in a randomized block design (RBD) consisting of two factors, namely the tillage system and nitrogen fertilization factors. The first factor is the treatment of tillage system (T) namely T0 = no tillage, and T1 = intensive tillage, while the second factor is without nitrogen fertilizer (N0) and high nitrogen fertilizer (N1). The data obtained will be tested for homogeneity by Bartlett Test and additives tested by Tukey Test. Furthermore, the data were analyzed by analysis of variance and continued with a BNJ test of 5% level. Observation of soil respiration was done 4 times, namely -1, 1, 2, 3 days after tillage. The results showed that soil respiration one day before to three days after the soil was treated in intensive tillage (OTI) was the same as the no tillage system (TOT), soil respiration -1 days after tillage to 3 days after tillage on nitrogen fertilization (100 N kg ha-1 ) given in the previous planting season the same as without fertilization (0 kg N ha-1), and there is no interaction between the tillage system and nitrogen fertilization on soil respiration.

Abstract: The objective of this work was to evaluate the residual effects of occasional soil tillage in a 17-year-old, no-tillage system, associated with liming and nitrogen fertilization, on the crop yields and chemical properties of a very clayey Oxisol in the South of Brazil. A randomized complete block design in split-split plots was used, with two soil managements (with or without plowing), two liming treatments (with or without the required dose to raise base saturation to 70%), five N doses applied on side-dress (0, 1, 2, 4, and 6 times the recommended amounts), and four replicates. A rotation system was used with corn and soybean in the summer, and with wheat and black oats in the winter. The residual effects of occasional soil tillage in a consolidated no-tillage system do not supplant those of liming applied on soil surface, in periods of water deficit, which subsidizes the recommendation to maintain the system consolidated. Excess N fertilization in no-tillage, with liming applied only on soil surface, may harm wheat yield, acidifying the topsoil and leaching Mg2+ to the subsurface soil layers. Without liming, soil acidification is more intense with N fertilization, which, however, favors the accumulation of organic matter on soil surface in a consolidated no-tillage system.
