Which one of the following crops is not cultivated in Karewas, the lacustrine deposits of sand, clay, loam, silt and boulders?

Karewas are unique lacustrine deposits found in the Kashmir Valley, formed during the Pleistocene period [1]. These deposits consist of sand, clay, loam, silt, and boulders, creating elevated tablelands or natural terraces [1]. The fertile and well-drained soils of the Karewas are highly suitable for specific agricultural and horticultural activities. They are particularly famous for the cultivation of saffron (Zafran), especially in the Pampore and Pulwama regions [4]. Additionally, Karewa soils support orchards of almond, walnut, apple, and peach [2]. While saffron, almond, and walnut are primary crops associated with these formations, ling nut (Trapa natans, also known as water chestnut) is an aquatic plant typically grown in lakes and marshy areas rather than the elevated, well-drained Karewa plateaus [1]. Therefore, ling nut is not cultivated in Karewas.
