Abstract
ABSTRACT Yield response data of crops to soil and water management are vital for maximizing profits. This research aimed to evaluate the yield of the ‘IPR Andorinha’ bean cultivar under distinct irrigation depths (0, 25, 48, 100 and 130 % of the net irrigation depth) and tillage systems (no-tillage and conventional tillage), during the Brazilian fall season. The experimental design was in strips with subdivided plots and four replications, with the factor soil management in the plot and irrigation depths in the subplot. No-tillage had an average grain yield 26.5 % higher than that of the conventional tillage. Both the soil management treatments presented a quadratic response (R2 > 90 %) to the irrigation depths applied, and the maximum yields were reached at 63.8 % (y = 2,452 kg ha-1) and 81.8 % (y = 1,789 kg ha-1) of the irrigation depth, respectively for the no-tillage and conventional tillage. However, the irrigation of bean cropped in the Brazilian fall season is not economically feasible for the no-tillage and conventional tillage when the price of the water millimeter is 43.19 and 33.27 times higher than the price of the bean kilogram, respectively, resulting in yields of 1,345.2 and 699.4 kg ha-1.
Highlights
Bean is one of the main products in the Brazilian diet, and this commodity is a meaningful source of proteins (23.4-26.7 %) and micronutrients (Pereira et al 2018).In the 2018/2019 harvest, the Brazilian area cultivated with bean was 2.922 million hectares and the production 3.017 million tons, with the Paraná state accounting for a total cultivated area and production of 13.53 and 20.53 %, respectively (Conab 2020).In some Brazilian regions, depending on climatic conditions and water availability, bean can be grown in three different crops (Marco et al 2012)
(from January 10, 2019, to February 10, 2020), the area was grown with corn under no-tillage (Avena sativa straw) and conventional tillage
As the experiment was carried out in the fall season, there was a trend toward the air temperature values to decrease throughout the crop development
Summary
Bean is one of the main products in the Brazilian diet, and this commodity is a meaningful source of proteins (23.4-26.7 %) and micronutrients (iron and zinc contents that can satisfy, respectively, 20.3 and 19.8 % of a person’s daily demand) (Pereira et al 2018).In the 2018/2019 harvest, the Brazilian area cultivated with bean was 2.922 million hectares and the production 3.017 million tons, with the Paraná state accounting for a total cultivated area and production of 13.53 and 20.53 %, respectively (Conab 2020).In some Brazilian regions, depending on climatic conditions and water availability, bean can be grown in three different crops (Marco et al 2012). In the 2018/2019 harvest, the Brazilian area cultivated with bean was 2.922 million hectares and the production 3.017 million tons, with the Paraná state accounting for a total cultivated area and production of 13.53 and 20.53 %, respectively (Conab 2020). In the northwestern Paraná state, a sandy soil texture predominates, which may reach up to 90 % of sand in particle-size analysis (Fidalski et al 2013, Thomaz & Fidalski 2020).
