“…It is also suggested, that pumice can be used as promoter of retention of moisture in the soil and increasing efficiency in water use at low cost. In this regard, studies conducted without crop in sandy substrates of sedimentary origin with 30% of industrial pumice waste (2.38-3.35 mm in diameter) found increased water-holding capacity of the substrate 44%, of which, 56%was available [7]. In this sense, the materials pomaceous discarded by blue jeans factories after the fabric softening and fuzz, become important in arid and semiarid regions of the world, where problems with water scarcity are found [8].…”

A factorial experiment (using RCBD design) with three replications was conducted in 2014 at the University of Tabriz-Iran, in order to determine the effects of pumice application (P1, P2, P3 and P4: control, 30, 60 and 90 tons per ha) on soil and water stress (I1, I2 and I3: 100%, 70% and 50% water requirement calculated from class A pan, respectively) on dominante weeds community percent. Results showed that community percent of weed species changed as a result of water stress and pumice application on soil. Distributions of Chenopodium album and Malva sylvestris were sensitive to water stress but, Amaranthus retroflexus and Solanum nigrum were neutral to water stress. In contrast, Amaranthus retroflexus, Cardaria draba, Setaria viridis, Sisymbrium irio, Xanthium strumarium, Convolvulus arvensis and Salsola rigida distribution were resistant to water stress. Community percent of Chenopodium album as sensitive species to water stress and Salsola rigida as resistance species to water stress positively affected by pumice application especially under water stress condition. Amaranthus retroflexus, Xanthium strumarium and Convolvulus arvensis were positively affected by pumice application under well and limited water supply conditions. In contrast, Cardaria draba, Sisymbrium irio and Solanum nigrum negatively affected by pumice under water stress and it had positive effect on community of these species under well watering conditions. Thus, application of pumice and water stress are two factors which change weed community precent.

Purple passion fruit crops are affected by salinity conditions in productive systems. The aim of this research was to evaluate the effect of the application of Ascophyllum nodosum extract on salinity stress in purple passion fruit plants at the vegetative stage of growth with and without grafting. Eight treatments were evaluated corresponding to the combination of grafting or non-grafting on the Passiflora maliformis rootstock, the presence or absence of salt stress, and the application or not of the A. nodosum biostimulant. Physiological and growth parameters were evaluated. Salinity significantly decreased (P<0.05) growth and stomatal conductance (gs), increased contents of photosynthetic pigments and did not affect the chlorophyll a fluorescence. The grafted plants presented a positive response (P<0.05) in chlorophyll relative contents (~63 SPAD units) and shoot length (~106 cm); lower gs (~163 mmol H2O m-2s-1), number of leaves (~43 leaves) and root weight (3.5 g of dry weight), and no change in chlorophyll a fluorescence. The biostimulant mitigated the salinity effect on gs and photosynthetic pigments. In the case of salinity, non-grafted purple passion fruit may present a better performance at the vegetative stage, and the biostimulant can have a slight mitigation effect on salt stress. However, if it is essential to use grafted plants for sanitary reasons, the evaluated salinity does not affect them drastically.
