Soil moisture tension as an alternative for improving sustainable use of irrigation water for habanero chilies (Capsicum chinense Jacq.)

Using splines in the application of the instantaneous profile method for the hydrodynamic characterization of a tropical agricultural Vertisol

“…Between June and November, during the rainy season, frequent and high-intensity rainfall occurs. In contrast, February to May is the dry/drought season, a period having the lowest rainfall and highest temperatures (Gutiérrez-Gómez et al, 2018).…”

“…The soil water matric head h was measured simultaneously with the soil moisture content measurement, using pressure gauge tensiometers (Irrometer©, model "R") installed at the same depths as the soil volumetric water content measurements. The tensiometers were calibrated with a manual suction pump (Migliaccio et al, 2015) and their field installation was performed in a similar manner to that described by Rivera-Hernández et al (2010), Alamilla-Magaña et al (2016) and Gutiérrez-Gómez et al (2018).…”

“…In agronomy, soil K(θ) relationships play an important role in determining the rate at which soil water enters the root system and thus play a decisive role in determining crop yield (Wetzel and Chang, 1987;Zhang et al, 2004). Crop yield has also been shown to be highly dependent on the value of soil water matric head h, used as an indicator of the onset of irrigation in different crops, such as potatoes (Solanum tuberosum) (Kang et al, 2004;Wang et al, 2007;Carli et al, 2014), bananas (Musa AAA) (Orozco-Romero and Pérez-Zamora, 2006), sweet corn (Zea mays) (Rivera-Hernández et al, 2009, rice (Oryza sativa) (Sudhir-Yadav et al, 2011;Mahajan et al, 2012), sunflowers (Helianthus annuus) (Carrillo-Ávila et al, 2015), sugar cane (Saccharum officinarum) (Alamilla-Magaña et al, 2016) and habanero peppers (Capsicum chinense Jacq) (Gutiérrez-Gómez et al, 2018), among others.…”

Botanical Myths: Fake News of the Contemporary World

“…This situation becomes even more intriguing when we imagine, for example, one vigorous plant individual at a present moment and, later on, the same plant individual shows signs of decline that, in some cases, to death. There is sufficient scientific evidence to affirm that plants are vigorous and healthy in favorable environmental conditions, whether these are abiotic factors (photoperiod, temperature, water regime, mineral nutrition) (TENENBOIM; BROTMAN, 2016) There are many passive approaches already documented in the literature to refute the myth, for example, the necessity for the pepper plant to require a tenuous adjustment of water potential in the soil, somewhere between -0.01 to -0.07 MPa (GUTIÉRREZ-GÓMEZ; CARRILLO-AVILA; LANDEROS-SÁNCHEZ; COH-MÉNDEZ et al, 2018). This means that if the hydric availability in the soil oscillates, until some values of the water potential, the plant will be able to absorb water from the soil solution and balance its cellular osmotic adjustment while keeping alive.…”

The Postgraduate Course in Tropical Agroecosystems: Facing the Challenges for Mexican Agriculture in the 21st Century

“…In the forestry part, the availability of nutrients in the production of commercial forest species is addressed (Montero et al, 2019;Rodríguez et al, 2014;Santiago et al, 2016). The contributions on the production of crops are more prolific and include basic crops, fruits, grass AGRO PRODUCTIVIDAD and forage, citrus fruits and energy crops (Aguas et al, 2014;Alamilla et al, 2016;Andrés et al, 2017;Calzada et al, 2014;Espinosa et al, 2018;García et al, 2016;García et al, 2019;Grifaldo et al, 2019;Guillén et al, 2018;Gutiérrez et al, 2018;Hernández et al, 2016;Hernández et al, 2019;Ibarra et al, 2018a;Ibarra et al, 2018b;Jaimez et al, 2015;José et al, 2017;Mendoza et al, 2019;Mendoza et al, 2015;Rueda et al, 2016;Rueda et al, 2018;Sánchez et al, 2018;Valdes and Pérez, 2019;Villanueva et al, 2019. The current PTA challenges suggest that the subject matter of the study and generation of knowledge integrate experiences of stakeholders in a transdisciplinary research process (CP, 2017). Nevertheless, the results show scientific contributions oriented to increasing productivity, in congruency with the development of scientific research in the last 60 years that fosters a highly productive and profitable agriculture, although with environmental and social consequences (Sarandón, 2019).…”
