“…The lowest profitability was shown by Pigeon pea/RT (2.45%), not considering the negative PM system (Table 5). Similar results were found by Kaneko et al (2010), where the corn profitability index followed the OP trend, in which the NT provided the highest profitability indices; as well as the results obtained by Santos et al (2004) who found greater profitability with the NT when compared to the other managements.…”

Although many green corn producers manage their agricultural properties informally, the production of this vegetable is socioeconomically relevant to the Brazilian Northeast. This work aims to estimate and analyze the production costs, profitability and return of green corn in different cultivation systems, in the Coastal Tablelands of Sergipano. For this purpose, data were collected from the 16th to the 18th year of cultivation of a long-term experiment, in a strip experimental design, where each strip corresponds to the soil management system (conventional cultivation (CC), no-tillage (PD)) and minimum cultivation (CM)), and four previous crops (Beans Caupí, Crotalária, Guandu and Milheto) were randomized to corn. Production costs, Gross revenue, Operating profit, Profitability index and Leveling point were determined. Greater productivity and Gross revenue were observed in the PD, and greater disbursements in the CC (R$ 8,184.59). PD had highest operating profit and profitability ratio, where Guandu/PD had the best performance (R$ 8,847.18 and 52.02% respectively). Guandu/CC presented negative operating profit and profitability index, characterizing itself as a non-viable alternative for the farmer. The identification and analysis of production costs is an important tool, as it enables the identification of more profitable crops, being the PD the most recommended.

“…Observa-se que o sistema IV (trigo/soja, ervilhaca/milho e aveia branca/ soja) que sucedeu pastagens perene de estação quente foi a alternativa de menor risco. Resultados semelhantes foram obtidos por SANTOS et al (2004), avaliando sistemas de rotação de culturas para trigo, em Passo Fundo, de 1994 a 1997. Neste caso, o sistema trigo/ soja, ervilhaca/milho e aveia branca/soja dominou os demais sistemas estudados.…”

O objetivo deste estudo de cinco anos foi avaliar o desempenho de cinco sistemas de produção: sistema I (trigo/soja, ervilhaca/milho e aveia branca/soja); sistema II (trigo/soja, pastagem de aveia preta + ervilhaca/milho e aveia branca/soja); sistema III [pastagem perene de estação fria (festuca + trevo branco + trevo vermelho + cornichão)]; sistema IV [pastagem perene de estação quente (pensacola + aveia preta + azevém + trevo branco + trevo vermelho + cornichão)]; e sistema V (alfafa para feno). As parcelas dos sistemas III, IV e V, retornaram para o sistema I, a partir do verão de 1996. O delineamento experimental foi em blocos ao acaso, com quatro repetições. Foram aplicados à receita líquida quatro tipos de análise nos sistemas de produção: análise da receita líquida, da média variância, da distribuição de probabilidade acumulada e da dominância estocástica. Pela análise da receita líquida e da média variância, não houve diferença significativa entre os sistemas estudados. O sistema IV mostrou-se a melhor alternativa de produção, levando-se em conta lucratividade e menor risco, pela análise da dominância estocástica.

“…In other studies, it was also found that the revenues from more diversified crop rotation systems were higher than those of crop rotations with less diversification (Santos et al 1999, Goplen et al 2018. One of the benefits An Acad Bras Cienc (2021) 93(2) e20191330 10 | 15 of high diversification in crop rotation is the capacity to reduce risk related to agricultural commodity price volatility and the price risk of other cultivars, or to counterbalance low prices through greater crop diversification (Santos et al 2004, Lehmanna et al 2013, Castro & Silva Neto 2018.…”

Diversifi ed crop rotation is an option for expanding producer incomes, and its adoption has presented a series of agronomic advantages compared to less diversifi ed crop rotation systems. In this context, the objective of this study was to verify if higherdiversifi ed crop rotation systems perform economically better than low-diversifi ed ones. To this end, we conducted an experiment in no-tillage crop areas in Londrina, in south of Brazil, for the years 2014/15 to 2016/17. The experiment design was randomized blocks, with six treatments, consisting of crop rotation systems with different levels of diversifi cation, and four replications. We observed that higher-diversifi ed crop rotation systems yield higher revenues and profi ts. Only these systems, specifi cally the ones that included canola-corn, crambe-corn, and saffl ower-soybeans, or wheat-corn+brachiaria, canola-corn, and edible beans-soybeans were economically feasible. Despite higher cost, diversifi ed systems with a greater number of commercial crops in winter presented higher profi ts. However, diversifi ed systems with a high proportion of cover crops in winter are economically infeasible because their net return is negative.
