“…In addition, the crop is able to exploit the soil well in a way that expresses high productivity even in soils without high fertility, being dispensable in liming. However, the studies found in the literature related to sweet potato fertilization show contradictory results, and local studies are essential to define the ideal fertilizer dose (Oliveira et al, 2017).…”

“…The harvest and evaluation of the experiment were carried out in March 2020. The harvest was carried out 180 days after planting since, in tropical soils the later harvest results in higher yields when compared to the usual four to five months after planting (Oliveira et al, 2017). The following parameters were evaluated: total productivity (TP) and commercial productivity (CP) in t ha -1 , followed by economic analysis of fertilization; number of total tuberous roots (NTR) and number of commercial tuberous roots (NCR) per plant; harvest index (HI) in percentage; of each tuberous root, the individual fresh mass (IFM) was expressed in g, length (L) and diameter (D) in cm.…”

Chicken manure is accessible to family farmers, is produced in large volumes, and has a low cost. Therefore, it can be an alternative to increase the productivity of sweet potatoes (Ipomoea batatas), which is a culture of socioeconomic importance. The objective of the study was to evaluate the productivity of sweet potatoes under different doses of chicken manure, with and without liming, comparing to the use of chemical fertilizer NPK, in very clayey soil, from the perspective of economic efficiency. The experiment was conducted in the field from September 2019 to March 2020 in Manaus, Amazonas, Brazil. The experimental design was in randomized blocks with four replications, in a split-plot scheme 2 × 5 + 1 (presence or absence of liming; five doses of chicken manure; and NPK, respectively. The evaluated parameters were: total and commercial productivity; number of total and commercial tuberous roots; harvest index; individual fresh mass, length, and diameter of tuberous roots. The effect of chicken manure was not influenced by the liming and there are no differences in agronomic values related to NPK. The dose of chicken manure that results in maximum production of the queen sweet potato variety is approximately 13 t ha-1, producing 25.2 t ha-1, while the resulting dose in maximum profit is approximately 12 t ha-1 with a production of the 25.1 t ha-1. The selling production directly to the final consumer increased profit by approximately 57.3%. Purchasing the input directly from the manufacturer reduced costs by approximately 74.5%. The use of chicken manure has a greater economic advantage compared to NPK in very clayey soil.

“…In Brazil, crop fertilization with bovine manure has stood out due to its benefits in both vegetable yield and quality, highlighting its potential use to enhance yield of tuberous crops, especially those grown in nutrient-poor soils (Oliveira et al, 2017), as observed for the yam crop (Silva et al, 2012).…”

A araruta ( Maranta Arundinaceae L.) é uma hortaliça não convencional com grande potencial econômico, mas pouco conhecimento quanto à sua nutrição mineral. O objetivo deste trabalho foi avaliar a produtividade e a pós-colheita de araruta 'comum' submetida a diferentes fontes e doses de fertilizantes orgânicos. O experimento em parcelas subdivididas foi disposto em quatro blocos de duas parcelas principais, cada uma dividida em cinco subparcelas. As fontes de fertilizantes (esterco bovino e ovino) foram aplicadas nas parcelas principais, sendo cinco doses de cada fertilizante líquido (0; 300; 600; 900 e 1.200 mL planta -1 semana -1) foram aplicados às subparcelas. Número de rizomas (NR), massa fresca dos rizomas (FMR), massa seca dos rizomas (DMR), peso médio do rizoma (ARW), rendimento do rizoma (RY), comprimento do rizoma (RL) e diâmetro do rizoma (RD) foram medidos . Melhores resultados para RY, FMR e RL de plantas de araruta 'comum' foram observados para o biofertilizante bovino em comparação com o biofertilizante ovino. Doses de fertilizantes variando de 737 a 1.200 mL planta -1 semana -1 são recomendadas para maximizar o rendimento e a qualidade pós-colheita da araruta 'comum'. RY de 212,51 t ha -1 e 207,1 th -1 foram obtidos quando 1.200 mL planta -1 semana -1 de esterco bovino e ovino foram aplicados em plantas de araruta cultivadas em vasos, respectivamente.

“…Its root tubers are consumed and are the main commercial part of this plant. Sweet potato has high yield potential and wide phenotypic and genotypic variability, but the average yield in Brazil is low: approximately 12 Mg ha -1 (Oliveira et al 2017). This is because most sweet potato crops are grown from local non-selected varieties and use a low level of technology, which results in yields below crop potential.…”

Estimating genetic parameters is an essential procedure to define strategies for breeding and selection of higher yielding genotypes. The use of a selection index can assist in decision making by combining the high yield trait with other desirable traits. The objective of this study was to verify the possibility of gains from selection in a sweet potato population to select potentially promising genotypes. The experiment was conducted in a randomized block design, with three plants per plot and two replications, consisting of 255 sweet potato genotypes and a commercial cultivar (256 treatments). The data were analyzed through REML/BLUP. Genetic gains were evaluated using selection indexes based on the rank sun. The plant population tested showed high genetic variability; 81.25% of the traits had genotypic coefficients of variation above 20%, which indicates conditions favorable to selection with considerable genetic advances. CERAT31-01, CERAT21-02, and CERAT51-30 can be recommended as the most promising genotypes.
