“…However, if the objective is shoot production, Sagrilo et al (2002) reported that, until 14 months after planting, the production averages of the total shoot remained constant, increasing until 17 months, with values approximately 50% higher than at the beginning of the harvest. Productivity is influenced by several factors, such as management, climate or soil but especially cultivars (Vieira et al, 2015), soil management (Filho et al, 2000), nutritional management (Alves Filho et al, 2015), cover plants (Otsubo et al, 2008), planting density (Tironi et al, 2019), harvest time (Mendonça et al, 2003), implantation time (Fagundes et al, 2010) pruning time (Aguiar et al, 2011a), weed control (Biffe et al, 2010), rainfall (Matos et al, 2016), temperature, photoperiod, and air humidity (Cury, 2008).…”

Cassava (Manihot esculenta) shows high phenotypic plasticity, acclimatization, wide adaptability, and resilience to adverse edaphoclimatic conditions. In this context, this systematic review aims to identify what were the factors that determined the production of cassava in Brazil in the last three decades, and to direct what are the possible perspectives of the crop in the country. The methodology to produce this review was based on studies that which integrate the academic information produced in different situations (1990-2020), environments, states, groups of researchers and existing scientific evidence for this theme. Based on the information, a binary matrix of information was assembled based on the following characters, plant density per hectare, soil type, city, state, average air temperature, planting line spacing, plant spacing on the planting line, implantation date, implantation station, harvesting station, productivity per hectare, days for harvest, liming, fertilization, precipitation and climate. It is evident that in the last 30 years the productivity of cassava in Brazil has been increased, mainly in low-income populations and those located in rural areas. There are prospects for increasing cassava production for fresh sale and industry. The crop is characterized as rustic, highly adaptive, tolerant of water stress and acidic soils, being highly influenced by the climate, rainfall, air temperature, and incident solar radiation. Productivity is determined by the time of implantation, liming, fertilization, density, and plant arrangement.

“…The supply of nutrients through the use of fertilizers in the cassava culture is an indispensable practice, despite being recognized as a rustic culture (Silva et al 2013). Alves et al (2012), Alves Filho et al (2015, Cuvaca et al (2017) and Biratu et al (2018) observed the effect of fertilization in increasing productivity for cassava. However, studies in which the isolated effect of phosphorus (P) on root production are still scarce (Sieverding and Howeler 1985;Pellet and El-Sharkawy 1993a;Pellet and El-Sharkawy 1993b;Enck et al 2017;Lima et al 2018;Omondia et al 2019), which demonstrates that it is necessary to intensify this line of research.…”

“…The adaptability of cassava varieties to various edaphoclimatic conditions, even in regions with dry climates and poor soils, has made it widely cultivated (Isitor et al 2017). The low productivity of the crop among the majority of producers occurs due to the insufficient use of agricultural inputs and the rudimentary management system (El-Sharkawy 2004; Alves et al 2012), that substantially limit the…”

Agronomic performance of cassava fertilized with phosphorus doses

We have evaluated the agronomic performance of table cassava cultivars fertilized with phosphorus doses in the Brazilian Semiarid Region. Two agricultural crops were grown at the Rafael Fernandes Experimental Farm, Mossoró, RN, from June/2018 to April/2019 and from June/2019 to April/2020. The experimental design was in randomized blocks, arranged in subdivided plots, with four replications. In the plots, doses of phosphorus were applied (0, 60, 120, 180 and 240 kg P2O5 ha-1), and in the subplots, the table cassava cultivars (Água Morna, BRS Gema de Ovo, Recife and Venâncio). The following were evaluated: dry matter of leaf, stem, and commercial root; harvest index; commercial root number; commercial productivity and aerial part productivity. The cultivars used had high root and aerial part productivities indicating that their irrigated cultivation is appropriate under the conditions of the Semiarid region of Rio Grande do Norte. The cultivars Água Morna, BRS Gema de Ovo and Recife are more efficient in the use of phosphorus, obtaining high productivity even in the absence of phosphate fertilization. The cultivar Venâncio is more responsive to phosphate fertilization, as it needs an input of this nutrient to increase its productivity.

“…Alves Filho et al (2015), avaliando a produtividade de mandioca sob o efeito da aplicação de diferentes doses de NPK, verificaram que houve aumento linear da produtividade de raízes em função da adubação mineral NPK. A mandioca se desenvolve e produz relativamente bem em solos de baixa fertilidade, no entanto apresenta respostas significativas ao uso de adubos, com aumentos expressivos na produtividade (FIALHO; VIEIRA, 2011).…”

RESUMOO trabalho foi desenvolvido objetivando avaliar a interferência da matocompetição sobre características produtivas e de crescimento da mandioca, submetida ou não à adubação química NPK, em diferentes períodos de controle das plantas daninhas. O experimento foi organizado em dois sistemas de manejo, com e sem adubação NPK, em delineamento de blocos casualizados, com três repetições e seis tratamentos mantidos livres de plantas daninhas. Aos 18 meses após o plantio, foi realizada a avaliação da produtividade de farinha e amido, área foliar total, índice de área foliar, teor de clorofila altura e diâmetro da mandioca. Os dados obtidos foram submetidos à análise de variância com nível de 5% de significância. Quando verificada diferença significativa procedeu-se à análise de regressão, com auxílio do software para cálculos estatísticos Sisvar versão 5.6. Os melhores resultados de produtividade de farinha, produtividade de amido, altura e teor de clorofila das plantas de mandioca foram obtidos no período em que houve a realização da capina até o final do ciclo da cultura (540 DAP). A adubação química aumentou a produtividade de farinha, a produtividade de amido e a altura das plantas. Não houveram diferenças significativas na interação período x adubação para nenhuma variável avaliada.

The experiment was organized in two management systems, with and without NPK fertilization, in a randomized block design, with three replications and six treatments kept free of weeds. At 18 months after planting, the evaluation of flour and starch productivity, total leaf area, leaf area index, chlorophyll content, and cassava diameter were evaluated. The data were submitted to analysis of variance with a level of 5% of significance. When a significant difference was verified, the regression analysis was performed using the
