“…The treatment with 25 %D was statistically greater than the others in both stages of measurement; likewise, the treatment with 30 %D was also greater in the second stage, the results obtained varied from 4.85 to 5.99 °Brix (Table 2), these values are higher than those found by Rivas et al (2012) The SST are a parameter of fruit quality that varies with the electrical conductivity of the SN and the hydric stress of the fruit during its development (Cespedes et al, 2004), the greatest water stress condition in this investigation was presented in the treatments of 25 and 30 %D, the tomato fruits of plants under this type of stress store mainly ions and organic molecules such as fructose and glucose (Munns, 2002), which increases the SST. The results of the present investigation are in agreement with those found by Chang et al (2012) who found that with SN drainage percentages lower than 30% or close, SST increase and as %D increases, SST decreases. pH of juice.…”

“…65, 6.62, 6.79, 6.37, 6.58, and 6.5. In the CE, these results are probably due to the fact that the plant absorbs more water than nutrients in proportion, and taking into account the amount of water lost through evaporation, the drained solution will have a concentration of solute (nutrients) greater than of water (solvent), thus increasing the electrical conductivity. Results similar to the present investigation found Chang et al (2012) with different percentages of drainage and percentage of zero drainage, since the electrical conductivity increased when decreasing the percentage of drainage obtaining from 2-6 dS m -1 with percentages of 30 to 50%.…”

La limitada disponibilidad de agua que cada vez es más severa a nivel mundial, exige un uso más eficiente del agua en la producción agrícola. Los sistemas hidropónicos cerrados hacen un uso más eficiente del agua, donde la solución nutritiva excedente es recuperada, regenerada y reusada en el mismo cultivo. El objetivo de este trabajo de investigación fue conocer los efectos en producción y calidad de frutos con seis porcentajes de drenaje (%D): 25, 30, 40, 45, 55 y 60%D de la solución nutritiva en un cultivo de tomate. Se usaron macetas con sustrato perlita fina previamente utilizado. La investigación se realizó en el año 2016 en la Unidad Académica de Agronomía de la Universidad Autónoma de Zacatecas. Se midió el número, tamaño, peso y rendimiento de frutos, productividad del agua y la calidad de los frutos (conductividad eléctrica, potencial de Hidrógeno, sólidos solubles, acidez e índice de madurez en zumo) en dos etapas de la producción. Hubo diferencia significativa en rendimiento y calidad para los tratamientos 3 y 4 y 1 y 2 respectivamente. Con % D de 40% se obtuvo mayor rendimiento, pero con 25% de drenaje se aumentó el contenido de sales y azucares en fruto y se obtiene la mayor productividad con respecto a los demás porcentajes.

Functional Design of Pocket Fertigation under Specific Microclimate and Irrigation Rates: A Preliminary Study

et al. 2022

View full text Add to dashboard Cite

Irrigation and fertilization technologies need to be adapted to climate change and provided as effectively and efficiently as possible. The current study proposed pocket fertigation, an innovative new idea in providing irrigation water and fertilization by using a porous material in the form of a ring/disc inserted surrounding the plant’s roots as an irrigation emitter equipped with a “pocket”/bag for storing fertilizer. The objective was to evaluate the functional design of pocket fertigation in the specific micro-climate inside the screenhouse with a combination of emitter designs and irrigation rates. The technology was implemented on an experimental field at a lab-scale melon (Cucumis melo L.) cultivation from 23 August to 25 October 2021 in one planting season. The technology was tested at six treatments of a combination of three emitter designs and two irrigation rates. The emitter design consisted of an emitter with textile coating (PT), without coating (PW), and without emitter as a control (PC). Irrigation rates were supplied at one times the evaporation rate (E) and 1.2 times the evaporation rate (1.2E). The pocket fertigation was well implemented in a combination of emitter designs and irrigation rates (PT-E, PW-E, PT-1.2E, and PW-1.2E). The proposed technology increased the averages of fruit weight and water productivity by 6.20 and 7.88%, respectively, compared to the control (PC-E and PC-1.2E). Meanwhile, the optimum emitter design of pocket fertigation was without coating (PW). It increased by 13.36% of fruit weight and 14.71% of water productivity. Thus, pocket fertigation has good prospects in the future. For further planning, the proposed technology should be implemented at the field scale.

This study aimed to evaluate the effect of planting density by cultivar on the growth, quality, and yield of melon (Cucumis melo L.) in hydroponics using coir substrates. Experiments were conducted using three domestic netted melon cultivars, namely 'Earl's Kingstar', 'Hero', and 'PMR Dalgona'. The plants were transplanted on March 19, 2019 to a venlo-type glass greenhouse. The spacing between the rows was 1.5 m and the planting density was 2.0, 2.7, and 3.3 plants/m 2 (the within-row
