Abstract
ABSTRACT Due to the water balance in the Brazilian Cerrado, it is not necessary to cultivate arugula in a rainfed system. Together with the lack of research on with this crop, it is necessary to study the response of genotypes to irrigation in this biome. Thus, the objective of this study was to determine the optimal irrigation depth and to identify the best arugula genotypes. Three arugula genotypes were field-tested during two cycles under the effect of four irrigation depths based on crop evapotranspiration. The parameters evaluated were root depth, SPAD index, number of plants and leaves per plant, plant diameter, fresh shoot mass and water use efficiency. The arugula presented the same demand for irrigation in the two cycles, and the genotypes and/or irrigation depths affected the evaluated parameters. The results support that the Folha Larga variety should be preferred by Brazilian Cerrado producers and irrigated with 90% replacement of crop evapotranspiration.
Highlights
The area planted with horticulture in Brazil is estimated at 800 thousand hectares, with a production of approximately 16 million tons (Biscaro et al, 2013)
The major consumer of horticultural is the city of Brasília-DF, the federal capital and the capital of the Cerrado alike, which has a population of approximately
According to Silva and Costa (2013), 82% of the population of Brasília-DF consume produce more than five times a week, 24% of which consume more than three daily servings
Summary
The area planted with horticulture in Brazil is estimated at 800 thousand hectares, with a production of approximately 16 million tons (Biscaro et al, 2013). According to Silva and Costa (2013), 82% of the population of Brasília-DF consume produce more than five times a week, 24% of which consume more than three daily servings This demand requires a production operation near this city. An alternative is the production of horticulture in the northwest of the State of Minas Gerais, since it shares a border with the Federal District. This region is contained in the Cerrado biome and stands out for its production of grains and livestock for milk, presenting few initiatives in the cultivation of produce. Due to this market potential of the Federal District and the increase in the number of rural settlements in this region (Sousa et al, 2011), there are good prospects for the production of produce, such as arugula, which is widely used in restaurants and pizzerias of the Federal District
