“…These results are consistent with other studies that, by poultry litter use on soybean, also reported increases on grain yield [12] [25]. This fact demonstrates the high potential of the combined use of mineral fertilizers with organic amendments, as a synergistic way to increase the soybean grain productivity [9] [26].…”

The use of organic wastes, as an alternative to inorganic fertilizer, can be an important strategy for Brazilian and tropical agriculture. Despite the importance, few field studies have been done for evaluating organic amendments on soybean crops in Brazil. The study aimed to evaluate the residual effects of the organic amendments poultry litter, farmyard manure and biochar combined with mineral fertilizer on some agronomic attributes of a soybean crop. A field experiment was carried out in a split-split-plot scheme, with three replicates in a randomized block experimental design. The organic sources (

“…A adição da maior dose de fertilizante, em relação a dose 0, promoveu acréscimos do teor desse elemento em 33, 28 e 32% para as adubações minerais, com esterco e combinadas, respectivamente. Carvalho et al (2011) Silva et al (2012), a elevação da CTC com a adição esterco bovino ao solo foi responsável pelo acréscimo da produtividade da cultura do inhame devido a disponibilidade de nutrientes para as planta, por um longo período. …”

ResumoA batata-doce geralmente é cultivada com baixos investimentos em adubação, todavia a cultura pode apresentar significativo incremento de produtividade quando é realizada adubação adequada ao seu cultivo. Neste trabalho objetivou-se avaliar a influência do uso de fontes e doses de fertilizantes na produtividade da cultura da batata-doce e em propriedades físicas e químicas do solo. O delineamento experimental foi em blocos ao acaso, no esquema fatorial 3x5, com três repetições. Os tratamentos do experimento foram constituídos por fontes de fertilizante (esterco de galinha, fertilizante mineral com composição química equivalente aos nutrientes encontrados nas doses de esterco de galinha e adubação combinada de esterco de galinha (50%) com adubo mineral (50%) com somatório de nutrientes equivalente aos nutrientes encontrados nas doses de esterco de galinha) e doses de fertilizante (equivalentes a 0, 3, 6, 9 e 12 t ha -1 de esterco de galinha). Como resultado do trabalho, verificouse que a cultura responde à adubação do solo, com acréscimos de produtividades total e comercial com a utilização de esterco de galinha, fertilizantes minerais e a combinação de ambos até as doses aproximadas de 5,8; 6,5 e 7,0 t ha -1 , respectivamente. A adubação com esterco de galinha, isolada ou combinada com adubo mineral, promove as maiores produtividades. Não há diferença na densidade do solo e na porosidade total em função de fontes de fertilizantes ou doses utilizadas. A adição dos fertilizantes promove acréscimos nos valores de pH e nos teores de P, K, Ca e Mg do solo em relação ao solo sem adição de fertilizantes.

In this study aimed to evaluate the influence of the use of different fertilizer sources and doses on sweet potato yield and on physical and chemical properties of soil. The experimental design was a randomized block in 3x5 factorial scheme, with three replications. The treatments were composed of fertilizer sources (chicken manure, mineral fertilizer with chemical composition equivalent to the nutrients found in chicken manure and blend of chicken manure (50%) with mineral fertilizer (50%) equivalent to the sum of nutrients found in chicken manure) and fertilizer doses (nutrients equivalent to 0, 3, 6, 9 and 12 t ha -1 of chicken manure). As result of study, it was found that the crop responds to soil fertilization with increases in total and commercial yields with the use of chicken manure, mineral fertilizers and the combination of both until the doses of 5.8, 6.5 and 7.0 t ha -1 , respectively. Fertilization with chicken manure, alone or in combination with chemical fertilizers, promotes highest yields. There is no difference in soil bulk density and in total soil porosity as a function of fertilizer sources or doses. The addition of fertiliz...

“…According to results by Carvalho et al (2011), in the evaluation of agronomic characteristics of the soybean crop, there was a linear increase for plant height, one thousand grain mass, number of pods per plant and grain yield for the worked doses, and although lodging was observed for higher doses, the authors recommend the use of the poultry bed in agronomic and economic terms for the soybean crop. Carvalho et al (2011), still reinforce the advantage of this technique when raising K and S contents in the soil.…”

A R T I C L E I N F O A B S T R A C TThe breeding and production of birds generate income and diversity of production in many rural properties, and has been increasing its share in the country's economy. However, the production process generates a large amount of waste, which in turn is characterized as an organic fertilizer with a high content of mineral nutrients, and that when well-managed, can be used as fertilizer crops. Soybean, considered the most important crop in the country, by production and for being a commodity, has the highest cost of production, fertilization, which is increased each year and decreasing the profit range of producers. The objective of this work was to evaluate the productive performance with the use of poultry bed in soybean as an alternative to chemical fertilization. The cultivar used was the BMX Vanguarda IPRO (IPRO 6160RSF) under the application of different doses of poultry bed previously moistened and covered by tarpaulin, previously composted in the field until the date of planting. The treatments consisted of: T1: Witness (free of fertilization); T2: Poultry bed in the concentration of 3.5 t ha-1 (CA 3,5 t); T3: Poultry bed in the concentration of 7.0 t ha-1 (CA 7.0 t); T4: Poultry bed in the concentration of 10,5 t ha-1 (CA 10,5 t); T5: Chemical fertilization (AQ) with NPK in formulation 02-18-18, applying 444.2 kg ha-1. The best result was obtained with the use of the CA 10.5 t ha-1 treatment, with a higher mass of nodules, higher plant height and higher productivity. It was concluded that the poultry bed at the dose of 10.5 t ha-1 can replace the chemical fertilizer in the soybean crop in the productivity question, as well as for the other agronomic characteristics, as early as the first year of cultivation.
