Economic Viability of Irrigation and Nitrogen Fertilization in Jambu Production in Brazilian Amazon

“…Lima Junior et al (2014) in a study carried out in Lavras -MG with two carrot cultivars under different soil water tensions, differently from what was found in this study, shows that the inputs represented the largest impacts on the total cost, reaching up to 64% of the total costs. The results found in this paper are in agreement with the results obtained by Pereira et al (2018) and Lima et al (2016), who found a greater participation in the variable costs of inputs followed by labor, studying the cauliflower and green pepper irrigated in Igarapé -aç u. words, this treatment required the lowest cost to produce 1 pack (600 g) of jambu. This evidences that the higher productivity is, lower the costs are, since there is the maximization of the resources employed in the cultivation system.…”

Carrot Cultivation Fertirrigated With Nitrogen by Surface and Subsurface Drip / Cultivo De Cenoura Fertirrigada Com Nitrogênio Por Gotejamento De Superfície E Subsuperfície

“…The efficiency of drip irrigation has been studied by several researchers in different crops, such as Lactuca sativa (Brunin et al 2019); Solanum lycopersicum L. (Silva et al 2019); Brassica oleracea var. botrytis (Pereira et al 2018); Cichorium intybus (Biscaro et al 2012); Ricinus communis L. (Souza et al 2005). The high uniformity of drip irrigation Brazilian Journal of Development, Curitiba, v.7, n.1, p. 9459-9473 Jan. 2021 system, close to 90%, provides greater fertirrigation efficiency and is currently considered one of the most important productivity factors for agriculture.…”

Determination of evapotranspiration and crop coefficient for cauliflower at Paranánorthwest region

“…Environmental conditions, mainly temperature, are limiting factors for the production, and the South and Southeast are the major producers regions in Brazil. However, management practices enable cultivation in the mid-season and summer with satisfactory profitability (FERREIRA et al, 2019;OLIVEIRA et al, 2018;PEREIRA et al, 2018).…”
