Description The advancing desertification coupled with increasing problems of salinity and drought warrants the development of appropriate technologies and identification of the crops capable of sustaining valuable food and fodder production in arid and semi-arid areas. Edible cactus (Opuntia ficus-indica) can provide a large range of
commodities in the areas with scarce and degraded available resources. Thus, it has raised renewed interest and hope to attain potential productivity in the stressed areas. A sizeable part of India is affected by salt and drought conditions, thus, potentially suitable for cultivation of edible cactus to generate alternate source of livelihood and employment. There is a need to generate information on its critical limits of salinity tolerance and ability to mitigate the salt stress in these areas. A pot experiment was conducted at Central Soil Salinity Research Institute, Karnal during 2008-2011. Clone 1280 was grown using two quality irrigation waters in combination with three soil salinity levels. The observations on growth suggests that the plant is moderately tolerant to soil salinity and most of the growth parameters, viz., number of sprouts, plant height and number of cladodes started declining at 6 dS m-1 soil salinity. No significant adverse effect of saline water irrigation was found on survival of cactus at ECiw 4 dSm-1 except reduction in the number of sprouts produced. The above ground parts of biomass production were found sensitive at ECe 6 dSm-1 soil salinity, while root biomass production was more sensitive to saline water irrigation rather than soil salinity. Finally, fruit quality characteristic of promising edible cactus clones and their potential of acceptability as a palatable fruit among general public was evaluated.
