“…The cost of seedlings was calculated considering the number of seedlings necessary for a population of 79,200 plants ha -1 , plus the estimated number of seedlings (5%) necessary to replace losses in the field during the budding phase, multiplied by the average weight of the seedlings used for cultivation and then multiplied by the purchase value of the seedlings, which corresponded to R$ 2.00 kg -1 (Heid et al, 2015).…”

The commercial part of the Peruvian carrot plant is subterraneous, requiring well-structured soils. Differences in seedling size and the use of organic residues may affect crop productivity and farmer income. This study aimed to assess the productivity and profitability of Peruvian carrot propagated using different seedling sizes (T1, T2, T3, and T4) and grown with broiler litter of different bedding materials (wood shavings and rice hull) as soil cover, arranged in a 4 × 2 factorial scheme in a randomized block design with five replicates. The highest production of fresh leaves (5.85 t ha-1), shoots (7.55 t ha-1), and commercial roots (6.30 t ha-1) were obtained with propagation using T2 seedlings. Broiler litter with wood shavings bedding provided the highest commercial root productivity (5.00 t ha-1

The global production of arrowroot is minimal, and this may be partially associated to the lack of standardized agronomic techniques for its commercial cultivation. This study aimed to assess the yield and profitability of arrowroot plants (‘Comum’ cultivar) grown using different plant spacings in the cropping row (20 cm, 25 cm, 30 cm and 35 cm) and a varying number of hilling applications (0, 1 and 2). The treatments were arranged in a 4 x 3 factorial scheme, in a randomized experimental block design, with six replications. After harvesting, the fresh and dry matter yields of leaves, rhizomes and roots were determined. Production costs and gross and net incomes were also calculated. The highest yields for fresh leaves (8.75 t ha-1), rhizomes (32.92 t ha-1) and roots (8.45 t ha-1) were obtained with a plant spacing of 20 cm. No interaction between the factors, neither significant differences for the use or not of hilling, were observed on the analyzed variables. The costs per hectare ranged from BRL 8,488.83 (35 cm without hilling) to BRL 10,376.23 (20 cm with two hillings). The highest yields and gross and net incomes were obtained with the spacing of 20 cm between plants.

“…O maior comprimento dos RFC de plantas de mangarito cultivadas com cama de frango base maravalha, quando comparado com a casca de arroz, pode estar relacionado com maiores teores de P, Ca, Mg e Fe da cama de frango (Tabela 1). Os resultados são coerentes com os dos estudos realizados por Torales et al (2014) e Heid et al (2015, que observaram elevação do P, K e Mg do solo após aplicação de cama de frango, ao avaliaram seu efeito na produção e comprimento de raízes comercializáveis de mandioquinha-salsa, que também é uma tuberosa. Já, o menor valor obtido sob o maior espaçamento entre plantas está de acordo com Fontes et al (2012) que, ao avaliarem a produtividade de batata em resposta às variações no espaçamento entre linhas, observaram que a quantidade de tubérculo comercial por área decresceu exponencialmente com o aumento do espaçamento entre plantas.…”

Resumo -O objetivo deste trabalho foi avaliar a influência de diferentes espaçamentos entre plantas (12,5; 15,0; 17,5 e 20,0 cm) e tipos de cama de frango adicionadas ao solo (com bases maravalha e casca de arroz e sem cama de frango), na produtividade e rentabilidade do mangarito. Os tratamentos foram arranjados no esquema fatorial 4 x 3, no delineamento experimental blocos casualizados, com quatro repetições. As maiores produtividades foram obtidas sob o menor espaçamento (12,5 cm), apresentando valores máximos de 1,25 t ha -1 , para rizoma mãe e 4,20 t ha -1 , para rizoma filho comercializável, com aumentos de 0,59 e 2,78 t ha -1 , respectivamente, em relação ao espaçamento de 20 cm entre plantas. Os custos estimados para produzir 1,0 ha de mangarito variaram em R$ 1.619,06, entre o maior custo (R$ 9.917,36), para o cultivo sob espaçamento de 12,5 cm e o menor custo (R$ 8.298,30), sob espaçamento de 20 cm, sem a adição de cama de frango. Para se obter maior produtividade de rizomas comercializáveis e maiores renda bruta e líquida, o cultivo de mangarito deve ser feito no espaçamento de 12,5 cm entre plantas e com cama de frango com base de casca de arroz.

The treatments were arranged in a 4 x 3 factorial scheme, in a randomized complete block design, with four replications. The highest yields were obtained in the smallest spacing (12.5 cm), presenting maximum values of 1.25 t ha -1 , for the mother cormel and 4.20 t ha -1 , for commercial cormels, with increases of 0.59 and 2.78 t ha -1 , respectively, in relation to the spacing of 20 cm between plants, which was the one that obtained the lowest productive means. The costs estimated to produce 1.0 ha of tannia as a function of the treatments under study varied by R$ 1,619.06 between the highest cost (R$ 9,917.36), determined for cultivation in spacing of 12.5 cm and the lowest cost (R $ 8,298.30), for cultivation at 20 cm spacing without the addition of broiler manure to the soil. In order to obtain higher yields and higher gross and net income of commercial cormels of tannia, the cultivation should be done at a spacing of 12.5 cm between plants and with addition of broiler manure with of rice husk base residue.
