As short cycle crops in substitution of potatoes we may suggest to grow one of the following vegetable crops :
Vegetable species with certain degree of tolerance to salinity:
Gourds and Pumpkins
Pumpkin: Cucurbita moschata (Duchesne) More adapted to high temperatures and wet tropics than Cucurbita maxima
Bottle gourd (Lagenaria siceraria), Bitter gourd (Momordica charantia), Snake gourd (Trichosanthes cucumerina)
Leafy vegetables:
Purslane (Portulaca oleracea)
Kale ( Brassica oleracea var alboglabra)
Swiss Chard ( Beta vulgaris L. var cicla), Spinach (Spinacia oleracea L.)
Fruit vegetables: Tomato (Lycopersicon esculentum).
The cultivars should be adapted to the local consumers preference and also availability of seeds.
Do check soil salinity before starting the next crop season |
