“…Baby corn yield is directly related to the amount of spikelets produced per plant, the higher the number of spikelets harvested, the higher the yield. In the present study, this relation was observed between 150 and 165 kg ha -1 of N. Nitrogen is the nutrient that provides the highest yield increases, however overdosing of this nutrient can cause soil and plant imbalance, negatively affecting the crop agronomic performance (Meneghetti et al 2012).…”

Baby corn is a growing crop in the agricultural setting, however there is still a lack of research in the area of fertilization, especially nitrogen fertilization. The objective of this study was to evaluate the influence of nitrogen fertilization on agronomic yield and quality of baby corn. Outlined in randomized blocks with four replications, the treatments consisted of five levels of nitrogen fertilization (50, 75, 100, 125 and 150%), based on the recommended dose for green corn crop (150 kg ha-1 of N). After harvesting, the following agronomic variables were evaluated: Number, productivity, dry matter, length and diameter of commercial and non-commercial spikelets. And the variables of post-harvest quality were: Soluble Solids, Titratable Acidity, Ratio of soluble solids and titratable acidity, Hydrogen-ion potential and firmness. Nitrogen fertilization at 150 kg ha-1 resulted in an increase in the total number of spikelets per hectare, around 405,000. There was an increase in productivity due to the increasing levels of nitrogen fertilization, with maximum yield of 4.4 t ha-1 at a dose of 165 kg ha-1 of N. The soluble solids content presented a maximum of 10.05 Â° Brix with the N applied to 222 kg ha-1. Nitrogen fertilization around 150 to 165 kg ha-1 increases the agronomic yield of the crop, without affecting its characteristics of quality.

“…They were defined based on the nitrogen concentration obtained from SWW physical-chemical analysis. The application rates are also similar to that used in the study of Meneghetti et al (2012), who defined SWW application rates based on nitrogen concentration in baby corn crop (0, 115, 230 and 345 m 3 ha -1 ). Besides the standard rates of 0, 100, 200 and 300 m 3 ha -1 , a treatment was carried out with the equivalent in available N (nitrate + nitrite + ammonia).…”

Physical Attributes of Soil After Swine Wastewater Application as Cover Fertilizer on Maize Crop and Black Oats Sequence

-The rate of swine wastewater application (SW) in agricultural production could result in the replacement of chemical fertilizers. However, SW destroys soil physical properties by decreasing pore bulk, which negatively affects both crop yield and development. In this context, this study aimed at monitoring the influence of swine wastewater as a cover fertilizer in maize and black oats in sequence on soil physical properties. Five application rates (0, 100, 200, 300 and 537 m 3 ha -1 equivalent to 0, 11.2, 22.3, 33.5 and 60 kg ha -1 N, respectively, based on the average nitrogen concentration in SW) were tested with four replications each. In the studied area, soil porosity, density, and water content, before maize sowing and at the end of the cycles of maize and black oats, were determined by the volumetric ring method. Data were submitted for regression analyses. There was a reduction in the macroporosity and total porosity of the soil when the SW application rate, before maize cultivation, was higher. The introduction of black oats helped to improve the physical quality of the soil and reduced the compaction of the surface layer from 0 to 15 cm and 100 to 300 m 3 ha -1 SW rates.Keywords: Swine manure.

ATRIBUTOS FÍSICOS DO SOLO APÓS APLICAÇÃO DE ÁGUA RESIDUÁRIA DE SUINOCULTURA APLICADA EM COBERTURA NA CULTURA DO MILHO E CULTIVOSEQUENCIAL DE AVEIA PRETA RESUMO -As taxas de aplicação de águas residuárias de suinocultura (ARS) utilizadas na produção agrícola podem substituir a adubação convencional, mas também podem prejudicar atributos físicos do solo pela diminuição do volume de poros, e consequentemente o rendimento e desenvolvimento das culturas. Neste contexto, o objetivo deste trabalho foi monitorar a influência do uso da água residuária de suinocultura como adubação de cobertura na cultura do milho e aveia preta em sequência sobre atributos físicos do solo. Cinco taxas de aplicação (0; 100; 200; 300 e 537 m 3 ha -1 sendo equivalentes a 0; 11,2; 22,3; 33,5 e 60 kg ha -1 de N, respectivamente, baseado na concentração média de N na ARS) foram testadas, com quatro repetições cada. No solo, foram determinados porosidade do solo, densidade, teor de água antes da semeadura do milho e ao final dos ciclos do milho e aveia preta, pelo método do anel volumétrico. Os dados foram submetidos a análises de regressão. Houve redução da macroporosidade e porosidade total do solo quanto maior a taxa de aplicação na cultura do milho. A introdução da aveia preta contribuiu para melhorar a qualidade física do solo e reduziu a compactação na camada superficial de 0-15 cm, para taxas de ARS de100 a 300 m 3 ha -1.

“…O uso desses resíduos na agricultura já é estudado e documentado (HERRMANN et al, 2016, PRIOR et al, 2015, MENEGHETTI et al, 2012MAGGI et al, 2013), sendo que a fertilização orgânica, isolada ou associada à adubação mineral, são tidas como alternativas economicamente viáveis (HERRMANN et al, 2016). Ainda, funcionando como como fonte de nutrientes ao sistema de produção agrícola torna se prática agrícola ambientalmente correta, fornecendo uma disposição final do efluente (HOMEM et al, 2014).…”

The system of intensive agricultural production, adopted by the majority of the producers, presents problems to the no tillage (SPD), mainly in the areas destined to the production of whole plant silage of maize. In this context, the objective of this work was to evaluate the fresh and dry mass of cover crops and soybean yield, under the cultivation of cover crops with and without swine wastewater (SWW). The work was developed in an agricultural property located in Matelândia, western region of Paraná. The experimental area consisted of seven management systems: soybean/silage/ black oats and turnips (SSOT); soybean/black oats and turnips (SOT); soybean/silage/chiseling + black oats and turnips (SSCOT); soybeans/silage and Brachiaria ruziziensis (SSB); soybean/ black oats and silage (SOS); soybean and silage (SS) and maize and soybean (MS), repeated for two consecutive years. In the treatments with SWW, 100 m 3 ha-1 year-1 were applied, divided in two equal doses: one on the corn and another on the cover plants. The experimental design was a randomized block design (RBD), with four repetitions per treatment, with four samples per repetitions. The application of SWW increased soybean yield as well as the production of fresh and dry mass of cover crops.
