“…In the IMC, an irrigation depth of 116.7 mm was observed, with a daily consumption of 3.9 mm day -1 in the 1 st cycle, and 75.0 mm cycle -1 with an average daily consumption of 2.5 mm day -1 in the 2 nd cycle. The values of the 1 st ICM cycle are close to those obtained in the IMS, and similar to the values obtained by Cunha et al (2018), possibly due to the obtained ETc values being similar in methodology. Elevated temperatures observed during this study may have influenced the increase in water consumption of the plants.…”

“…Due to the differentiation of each method, the accumulated depth values possibly influenced this factor. That fact was observed in several studies (Cunha et al, 2018;Moline et al, 2015;Cunha et al, 2013), which proves that the addition of water increases crop vigor and changes its growth. However, the stress caused by water excess may also be a factor to be considered in this evaluation, as stated by Souza et al (2019a), in studies on water table depth and its influence on arugula crop productivity, where the authors observed that excessive water can harm plant development.…”

Due to the increase in water and energy tariffs, in addition to the limited amount of these resources, the automation of irrigation can help farmers to increase the production of agricultural crops. Therefore, the objective of this research was to evaluate different irrigation managements between manual and automatic in the production of arugula in a protected environment, in order to determine the productive potential in the cultivation of vegetables. The experiment was conducted in randomized blocks with four irrigation management strategies, divided into automatic and manual managements: automatic irrigation management via soil (IAS); automatic irrigation management via climate (IAC); manual irrigation management via soil (IMS) and manual irrigation management via climate (IMC). The treatments were applied to the arugula (Eruca Sativa L.) crop during two production cycles, and their effect on biophysical aspects of plants and irrigation water productivity was evaluated. For the fresh mass variable, the IAC (17.75 g plant -1 ), IAS (12.38 g plant -1 ), and IMC (8.63 g plant -1 ) treatments, in the 1 st cycle, were statistically similar to each other, whereas in the 2 nd cycle, only the IAC (16.29 g plant -1 ) and IAS (19.80 g plant -1 ) treatments had this statistical similarity. Automatic managements can be recommended based on this research, however, considering the financial difficulties of the small farmer, IMC may be a desirable option in unfavorable economic conditions.

“…The Northwest of Minas Gerais presents annual averages of temperature and precipitation of 25 °C and 1,200 mm, respectively (Cunha et al, 2018). Its topography is gently undulating and the regional climate is Aw according to the Köppen classification, with a dry winter and precipitations concentrated in the summer.…”

“…After removal of the entire root system, the soil adhered to the roots was retired and the plant was taken to measure the distance between the collar and root end using a 0.001 m scale ruler. These measures were performed in six plants previously identified at the beginning of the crop cycles, as in Cunha et al (2018).…”

Agronomic Performance of Radish Genotypes Under Different Irrigation Depths

In radish production, the choice of proper genotypes and irrigation regime is of great importance to achieve success. In light of this, the current study aimed to evaluate the agronomic performance of a few radish genotypes under different irrigation strategies. The plants were grown in the city of Unaí-MG, in Brazil, under field conditions, and during two cycles, one of 40 days (from February 28 to April 8, 2015) and other of 51 days (from May 9 to June 28, 2015). The experimental design was a randomized block design in a split-plot arrangement with four replications. The treatments consisted of four irrigation strategies (50, 75, 100, and 125% of crop evapotranspiration-ETc) applied by a dripping irrigation system, while subplots consisted of three radish cultivars (Comet, Saxa, and Crimson Giant). We evaluated the following parameters: root system depth, leaf chlorophyll content, shoot fresh matter, diameter and length of tuberous root, number, and mass of commercial and non-commercial tuberous roots, and water use efficiency. All the radish genotypes showed no differences for agronomic characteristics. Under Brazilian Cerrado conditions, the most suitable irrigation strategy for radish crops is 100% of ETc.

“…Among the irrigation systems, drip irrigation has been successfully adopted for crops since it presents a higher water use efficiency, lower energy consumption, allows the use of fertigation, and reduces the incidence of diseases by providing less leaf wetness than sprinkling (BATISTA et al, 2009). Several authors have recommended the drip irrigation system in arugula cultivation (MOLINE et al, 2015, FREITAS et al, 2017CUNHA et al, 2018).…”

The region of the Zona da Mata of Minas Gerais stands out in the production of vegetables. To achieve the success in this activity, it is important to choose suitable cultivars and apply irrigation correctly. This study aimed to determine the optimum irrigation depth and evaluate new commercial arugula cultivars in the Zona da Mata of Minas Gerais. The cultivation was carried out in a greenhouse during three cycles with periods of 33 (January 11, 2016 to February 12, 2016), 36 (March 1, 2016 to April 5, 2016), and 36 (April 12, 2016 to May 17, 2016) days. The experimental design was a randomized complete block design with five replications, five irrigation depths (50, 75, 100, 125, and 150% of the crop evapotranspiration-ETc) in the plots, and three arugula cultivars (Antonella, Cultivada, and Folha Larga) in the subplots. A drip irrigation system was used. The parameters evaluated were root depth, root fresh mass, plant water potential, leaf temperature, number of commercial leaves, total number of plants, fresh shoot mass, and water use efficiency. Arugula cultivars did not present differences in their agronomic characteristics. An irrigation depth of the 50% ETc is recommended if the soil moisture is under the field capacity at the beginning of the arugula cycle.
