“…From the data collected in the field, a specific value scale relating rice stomatal conductance to the crop water stress index was developed. This approach is important as there are reference scales for other crops, such as beans [30], to monitor whether the crop is within the range of optimal water conditions.…”

In the face of the climate change crisis, the increase in air temperature negatively impacts rice crop productivity due to stress from water scarcity. The objective of this study was to determine the rice crop water stress index (CWSI) and stomatal conductance (Gs) under different irrigation regimes, specifically continuous flood irrigation treatments (CF) and irrigations with alternating wetting and drying (AWD) at water levels of 5 cm, 10 cm, and 20 cm below the soil surface (AWD5, AWD10, and AWD20) in an experimental area of INIA-Vista Florida and in six commercial areas of the Lambayeque region using thermal images captured with thermal sensors. The results indicated that AWD irrigation generated more water stress, with CWSI values between 0.4 and 1.0. Despite this, the yields were similar in CF and AWD20. In the commercial areas, CWSI values between 0.38 and 0.51 were obtained, with Santa Julia having the highest values. Furthermore, a strong Pearson correlation (R) of 0.91 was established between the CWSI and Gs, representing a reference scale based on Gs values for evaluating water stress levels.

“…This behavior is influenced by the interaction between soil, plants, and the atmosphere, with environmental conditions playing a significant role in stomatal opening and closure and affecting plant physiological responses (Huntingford et al, 2015). Stomatal conductance values serve as indirect indicators of soil moisture, with values above the optimum range (0.20 to 0.30 mmol m -2 s -1 ) indicating luxury water consumption and values below causing stress (Vega & Mejía, 2017).…”

Conducting studies that assist in the evaluation of agroecosystems is essential for advancing biodiverse and sustainable agriculture. This study aimed to assess the impact of intercropping on the photosynthetic activity of Arabica coffee plants. The experiment was conducted in the municipality of Alegre, Espírito Santo, southeastern Brazil. Three coffee cropping systems were studied: Arabica coffee monoculture; Arabica coffee intercropped with Nanicon variety banana; and Arabica coffee intercropped with Nanicon variety banana and Juçara palm. The Arabica coffee variety used was Catuaí Vermelho IAC 44, planted in 1991, with a spacing of 3.0 m between rows and 2.0 m between holes, accommodating two plants per hole. In 2010, coffee trees underwent mid-height pruning (low-cutting pruning), and the Nanicon bananas were planted between rows with a spacing of 5.0 x 3.0 m. Three years later, palm seedlings were planted in the same rows as the banana plants, with a spacing of 5 x 3 m. Five experimental units were randomly selected for each cropping system. The evaluated variables included chlorophyll indexes (chlorophyll a, chlorophyll b, total chlorophyll, and chlorophyll a/b ratio) and gas exchange parameters (net CO2 assimilation rate, stomatal conductance, intercellular CO2 concentration, transpiration, intrinsic water use efficiency, instantaneous water use efficiency, and carboxylation efficiency). Regarding chlorophyll indexes, differences were observed only in chlorophyll b, with monoculture coffee displaying the highest values. In terms of gas exchange, intercropped coffee exhibited lower values of intrinsic and instantaneous water use efficiency, and higher values of stomatal conductance and transpiration. The highest net assimilation rate values were observed in coffee with banana intercropping, while the highest water use efficiency was found in coffee in monoculture. In summary, monoculture coffee showed the highest values for most of the variables related to photosynthetic activity, followed by Arabica coffee intercropped with banana, which stood out for achieving the highest net assimilation rate.
