  • Geotextiles influence on the formation of soil wet bulbs and the
           production of drip-irrigated lettuce

      The influence of nonwoven geotextiles on the formation of wet bulbs and on the vegetative development of cv. Vanda lettuce was evaluated. The study was conducted in a greenhouse using a complete randomized block design with five repetitions. Treatments consisted of a control and three geotextiles grammages: N26.1, N30.1 and N40.1. To evaluate soil wet bulbs, 16 tensiometers were used. They were spaced 5 cm apart at depths 10, 20, 30 and 40 cm. Soil moisture readings were taken before and 2, 12, 24 and 48 hours after irrigation. Each lettuce vegetative development treatment was assessed by evaluations conducted every five days regarding largest leaf length and width, largest width among leaves and number of leaves. At the end of the cycle, fresh and dry shoot and root biomass were weighted to calculate the crop yield. In the formation of soil wet bulbs, the treatment that presented the best water distribution at the assessed depths was the treatment with geotextile N40.1. The highest values of vegetative parameters of lettuce were observed for the treatment with geotextile N40.1, with the largest leaf length. The highest number of leaves per plant was observed 20 days after transplanting (DAT).

      ɑ-Tocopherol (ɑTOC) is a vitamin and antioxidant compound that plays a crucial role in amelioration of biotic and abiotic stresses. It has been found that it improves salt-tolerance in some plant species. Two field experiments were conducted in 2013/14 and 2014/15 to evaluate the potential effects of foliar applications with 0.5 and 1.0 mM ɑTOC on growth, yield, plant water relations, osmoprotectants and the activity of antioxidant system of two onion varieties (i.e., Giza 20 and Giza Red) “classified as salt-sensitive” under saline soil condition (ECe = 7.94 - 8.81 dS m-1). Exogenous application of ɑTOC significantly improved salt stress tolerance in onion plants by reducing the endogenous H2O2 and lipid peroxidation, and increasing enzymatic (i.e., superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase) and non-enzymatic (i.e., ascorbic acid and glutathione) antioxidant activity. However, Giza 20 was more sensitive to salinity, while it was more responsive to ɑTOC treatment. Moreover, ɑTOC application significantly affected photosynthesis efficiency and plant water status as evaluated by relative water content and membrane stability index. These results were positively reflected in plant growth, productivity and water use efficiency under salt stress conditions, indicating that ɑTOC may participate in the enzymatic and non-enzymatic antioxidants. Therefore, foliar application of ɑTOC could be used to induce salt-tolerance in onion plants.
