Tomato is a high potassium and calcium requiring crop. Potassium is removed at a rate ~80% higher than nitrogen. Calcium deficiency inevitably produces "blossom-end rot" of the fruit. Tomatoes are rather resistant to salinity, and cherry-tomatoes even develop a sweeter taste when grown under moderate salinity. Tomato is a warm-season vegetable crop that is sensitive to frost and is killed by freezing temperatures. Growth requires temperatures at 10-30 °C, and the plant does not set fruit when night temperatures are consistently below 10 0C, and will not develop properly when temperatures exceed 350C. Tomatoes can have either a determinate or indeterminate growth habit. It can grow successfully under open field conditions, as well as in greenhouses. Best tomato mineral nutrition regime includes the use of CRFs in open fields, fertigation with fully-soluble fertilizers and foliar feeding.
