“…The chemical characteristics of the organic compost of swine manure differed from those found by Seidel et al (2010), these found higher values in pig liquid fertilizer: N = 37.91; P = 14.81; K = 19.32; Ca = 66.42 g dm -3 .…”

Pig farming is considered one of the activities with the greatest environmental impact due to the erroneous disposal of swine waste. The present work aimed to produce an organic compost using waste from pig production and evaluate its chemical characteristic, corn yield under doses of this organic compost and soil nutritional quality before and after the experiment implementation. The Corn was fertilized at sowing and 30 days after plant germination using organic compost from pig waste at the doses: 0, 2, 3, 4 and 5 t ha-1. The Corn used was CATIVERDE 02 and were seeded at 1.0 m spacing between rows and 0.40 m between plants, in a total area of 240 m2. The experimental design was randomized blocks with four replications and five doses of organic compost. The parameters evaluated for corn were: plant height, stem diameter, weight and corncob length. Fertilization with swine organic compost increases in soil P, K, Ca, even after the corn harvest. The best treatment was with a dose of 5 t ha-1, as it resulted in higher plant height (1.85 m) and corn cob weight (261 g).

“…Studying fertilization with NPK and split dose of PS (a total of 62 m 3 ha -1 ), with and without the addition of EI, applied in pre-sowing and topdressing in corn, in a Red Acrisol, these authors also did not observe difference between the NPK and the PS, regardless EI addition. On the other hand, in a Red Ferrasol, Seidel et al (2010) observed that the PS and mineral fertilizer did not differ on corn grain yield. In the first crop season of this current study, there was also no difference between soil fertilized with PS or NPK, and with EI addition in the corn grains and dry mass yields (Alves et al, 2017).…”

The incorporation of nitrogen (N) fertilizers in the soil and the use of enzyme inhibitors (EI) can improve the efficiency of N fertilization by reducing losses by ammonia volatilization and nitrate leaching. This study aimed to evaluate the efficiency of EI addition and fertilizer incorporation on both grain and dry mass yields of corn as well as on some soil chemical properties, with focus on N availability. A field experiment was carried out for three years in randomized blocks with four replications. The treatments consisted of a 2 × 5 factorial, including two forms of fertilizers application: superficial (SUP) and incorporated (INC), allocated in the plots; and five fertilizations: mineral fertilizer (NPK); NPK + EI; pig slurry (PS); PS+EI; and control (TEST), allocated in the subplots. The soil mineral N content was determined at 30, 60, and 90 days after fertilizer application (DAA) and these times were considered as sub-subplots. All fertilizers increased the dry corn matter and grain yields and the soil availability of N, P, and K, mainly in the upper layer (0.00-0.05 m). However, only the PS promoted higher productivity when incorporated into the soil relative to the soil superficial application. The incorporation of fertilizers increases soil available P but has little effect on soil mineral N. The EI addition to the fertilizers promotes higher soil mineral N contents in the soil until 30 and 60 DAA respectively when superficially applied and soil incorporated, although this does not increase the corn productivity.

“…Na análise dos componentes de produtividade do milho, nota-se que a menor dose de DLS (50%) proporcionou maior número de espigas por metro quadrado se comparado à testemunha, no entanto, não diferindo significativamente para as demais doses de DLS e NPK. Segundo Seidel et al (2010), que ao avaliar doses de DLS em comparação com a adubação mineral, obtendo resultados similares ao presente trabalho, para produtividade de milho, as diferentes doses de DLS utilizadas na adubação de base, quando comparadas à adubação química (NPK), não diferiram entre si estatisticamente, demonstrando a eficiência dos dejetos como biofertilizantes.…”

“…Na região noroeste do Rio Grande do Sul os dejetos líquidos de suínos (DLS), têm destaque pela grande quantidade gerada e constituem uma fonte alternativa de adubação aos fertilizantes minerais tradicionais no desenvolvimento da cultura do milho, seja pela presença de nutrientes essenciais como o nitrogênio, fósforo e potássio, micronutrientes e material orgânico, que favorecem o equilíbrio e o aumento da fertilidade do solo (MENEZES et al, 2018). Além disso, com os altos custos da produção, principalmente pelo uso de fertilizantes minerais, a utilização do biofertilizante de origem dos suínos torna-se viável, visto que na atualidade a agricultura busca o aumento da produtividade e a redução de custos (SEIDEL et al, 2010).…”

O objetivo do trabalho foi avaliar o desempenho do milho cultivado com diferentes doses de dejeto líquido suíno (DLS), comparado à adubação mineral (NPK) e sem adubação. Foram avaliadas quatros doses de DLS a partir da necessidade da cultura (50%, 100%, 150% e 200%), NPK e sem adubação (testemunha), com cinco repetições para cada tratamento, com delineamento de blocos casualizados em condições de campo. Foram determinadas a produção de matéria seca total (MST), colmos (MSC) e folhas (MSF), os componentes de produtividade comprimento de espigas (CE), número de fileiras de grãos por espiga (NFGE), número de grãos por espiga (NGE) e número de espigas por metro quadrado (NEMQ), a produtividade de grãos (PG) e o índice de colheita (IC) do milho. As doses de 100%, 150% e 200% de DLS se equipararam ao NPK, tanto para produção de MST (média 6.077 kg/ha), quanto para MSC (4.000 kg/ha) e MSF (2.076 kg/ha). O milho fertilizado com 50% de DLS apresentou maior NEMQ (23) se comparado à testemunha (19) e não houve diferença significativa entre as doses de DLS e NPK (média 20,9). A dose 200% DLS se equiparou ao tratamento NPK no NGE (média 412), no NFGE (12,1) e PG (12.674 kg/ha). As doses de DLS 50, 100 e 150% da recomendada não são equivalentes à adubação NPK, reduzindo, respectivamente, 175, 115 e 114% a PG.

Pig slurry doses affect plant growth and corn grain yield ABSTRACT: The aim was to evaluate the performance of corn grown with different doses of pig slurry (PS), compared to mineral fertilization (NPK) and without fertilization. Four doses of PS were evaluated from the need of the crop (50%, 100%, 150% and 200%), NPK and without fertilization (control), five replications each treatment, with a randomized block design under field conditions. The production of total dry matter (DM), stems (DMS) and leaves (DML), yield components ear length (EL), number of rows of grains per ear (NRGE), number of grains per ear (NGE) and number of ears per square meter (NESM), grain yield (GY) and corn harvest index. The doses of 100%, 150% and 200% of PS were equivalent to NPK, both for DM production (mean 6,077 kg/ha), and for DMS (4,000 kg/ha) and DML (2,076 kg/ha). Corn fertilized with 50% PS showed higher NESM (23) compared to the control (19) and there was no significant difference between the doses of PS and NPK (mean 20.9). The 200% PS dose matched the NPK treatment in NGE (mean 412), NRGE (12.1) and GY (12,674 kg/ha). The PS doses of 50, 100 and 150% of the recommended are not equivalent to NPK fertilization, reducing, respectively, 175, 115 and 114% of GY. Keywords: Zea mays; organic fertilization; animal manure; fertilization efficiency.
