“…It is more realistic for plant roots to be exposed to multiple salts simultaneously due to the specific ion effects as wells as competitions among ions (Farooq et al, 2015), but very few studies have been conducted in soil containing salt. Schiattone et al (2017) mixed two salts (NaCl and CaCl 2 ) with soil to investigate water use and rocket crop performance under different salt-stressed conditions. The results showed that the increasing soil salt content decreased leaf size and numbers, water use, and yield.…”

Interactive effects of reduced irrigation and salt stress on leaf physiological parameters, biomass accumulation, and water use efficiency (WUE) of tomato plants at leaf and whole plant scales were investigated in a field experiment during 2016 and a greenhouse experiment during 2017. Experiment utilized two irrigation regimes (full, 2/3 of full irrigation) and four soil salt regimes (0, 0.3, 0.6, 0.9% in 2016 season; and 0, 0.2, 0.3, 0.4% in 2017 season). Three salts, sodium chloride, magnesium sulfate, and calcium sulfate (mass ratio of 2:2:1), were homogeneously mixed with soil prior to packing into containers (0.024 m 3 ). Li-COR 6400 was used to measure tomato leaf physiological parameters. Instantaneous water use efficiency (WUE ins , μmol mmol −1 ) and intrinsic water use efficiency (WUE int , μmol mol −1 ) were determined at leaf scale, yield water use efficiency (WUE Y , g L −1 ), and dry biomass water use efficiency (WUE DM , g L −1 ) were determined at whole plant scale. Plants irrigated with 2/3 of full irrigation with zero soil-salt treatment had higher dry biomass and yield per plant, resulting in the highest WUE DM and WUE Y at whole plant scale. Increasing soil salinity decreased dry biomass and yield, leading to greater decreases in whole plant WUE DM and WUE Y under both irrigation treatments. At full irrigation, no decreases in stomatal conductance (g s , mol m −2 s −1 ) and slight increase in photosynthetic rate (P n , μmol m −2 s −1 ) led to higher WUE int at leaf scale during both years. Under full and reduced irrigation, increasing soil salt content decreased P n and transpiration rate (T r , mmol m −2 s −1 ) and led to reductions in WUE ins at the leaf scale. However, compared to full irrigation, reduced irrigation improved WUE ins with a significant decline in T r in no salt and 0.3% soil-salt treatments during both years. For soil salt content of 0.6%, stomatal limitation due to salt stress resulted in higher WUE int , but soil salt content of 0.9% decreased WUE int due to non-stomatal limitation. Soil salt content significantly decreased sap flow, with the maximum variation of daily sap flow per plant of 7.96–31.37 g/h in 2016 and 12.52–36.02 g h −1 in 2017. Sap flow rate was linearly related to air temperature (T a , °C), solar radiation (R s , W m ...

“…Several studies also showed that the LA of cabbage (SANOUBAR et al, 2016) and rocket (SCHIATTONE et al, 2017) is sensitive to salt stress, which also are species of Brassicaceae family. Sanoubar et al (2016) reported similar decreases to those found for in the present work, with relative decrease of 62% in LA of cabbage plants grown in a hydroponic system with high ECsol (8.72 dS m -1 ) when compared to the control (ECsol 2.68 dS m -1 ).…”

The Brazilian semiarid is historically characterized by the water scarcity of good-quality. In this region there is great availability of groundwater reserves, however, these waters has high concentrations of dissolved salts, that makes them inappropriate to be used in the irrigation of most crops. The objective of this study was to evaluate the growth, production and salinity tolerance of three cauliflower cultivars in hydroponics NFT (Nutrient Film Technique), subjected to different electrical conductivities of the nutrient solution (ECsol) prepared with saline water. The experiment was carried out in a randomized blocks design in split-plot, with six replications. The plants were subjected to six levels of ECsol (1.94 - control, 3.24, 4.10, 5.04, 5.92 and 7.01 dS m-1) in the main plots, with three cauliflower cultivars (‘Piracicaba de Verão’, ‘Sabrina’ and ‘SF1758’) in the subplots, which were grown in the same hydroponic channel. Vegetative growth, inflorescence production and salinity tolerance of cultivars were evaluated. In general, except for the number of leaves, leaf width and fresh matters of leaves and shoot, the different ECsol levels negatively influenced the vegetative growth and inflorescences yield of cultivars cauliflower. The cultivars ‘Piracicaba de Verão’ and ‘Sabrina’ were considered moderately sensitive to salinity, while cultivar ‘SF1758’ was moderately tolerant to salinity.

“…Therefore, standardizing the agronomic practices ( Figure 6) for such uncultivated edible crops is another major step for optimizing their resource use and also for improving the yield and nutritional quality [7]. Though the cultivation practices have been optimized for some of the wild species (for example, pigeon pea [40]; wild rocket [52]; terracrepolo [53]; Physalis sp. [54] etc.…”

“…Since a majority of the wild crops are hardy and resilient to diverse climatic conditions, they can be used as border crops, as crop breaks, intercrops and also for multi-cropping and integrated farming practices [58]. Importantly, the cultivation of such wild crops will result in species diversification though multiple cropping and Though the cultivation practices have been optimized for some of the wild species (for example, pigeon pea [40]; wild rocket [52]; terracrepolo [53]; Physalis sp. [54] etc.…”

Domesticating the Undomesticated for Global Food and Nutritional Security: Four Steps

Ensuring the food and nutritional demand of the ever-growing human population is a major sustainability challenge for humanity in this Anthropocene. The cultivation of climate resilient, adaptive and underutilized wild crops along with modern crop varieties is proposed as an innovative strategy for managing future agricultural production under the changing environmental conditions. Such underutilized and neglected wild crops have been recently projected by the Food and Agricultural Organization of the United Nations as ‘future smart crops’ as they are not only hardy, and resilient to changing climatic conditions, but also rich in nutrients. They need only minimal care and input, and therefore, they can be easily grown in degraded and nutrient-poor soil also. Moreover, they can be used for improving the adaptive traits of modern crops. The contribution of such neglected, and underutilized crops and their wild relatives to global food production is estimated to be around 115–120 billion US$ per annum. Therefore, the exploitation of such lesser utilized and yet to be used wild crops is highly significant for climate resilient agriculture and thereby providing a good quality of life to one and all. Here we provide four steps, namely: (i) exploring the unexplored, (ii) refining the unrefined traits, (iii) cultivating the uncultivated, and (iv) popularizing the unpopular for the sustainable utilization of such wild crops as a resilient strategy for ensuring food and nutritional security and also urge the timely adoption of suitable frameworks for the large-scale exploitation of such wild species for achieving the UN Sustainable Development Goals.
