Calcium carbide (ethylene producing compound) enhanced N loss of Urea and did not showed any beneficial effect on improving yield efficiency (Zhang et al., 1992). Bronson et al . (1993) studied the effect of nitrogen fertilizer and nitrification inhibitors and found that N 2 O emission from fertilized plots was 16 times greater than unfertilized plots.

Upon application on fruits, calcium carbide comes into contact with moisture and releases acetylene gas, which has fruit ripening characteristics similar to ethylene [].On the other hand, in the presence of moisture and at neutral pH, ethephon is decomposed into ethylene gas, biphosphate ion, and chloride ion [].Individually, these chemicals can have adverse effects on human health [1, 5 – 7].

Prevention. Calcium in plantavailable form should be added to soil where tomatoes, peppers and eggplant (which are also susceptible to blossomend rot, for the same reasons) are to be grown. The pH of the soil should also be corrected to around to this is not done, calcium in the soil might not be available to plant roots.

In 1901, Ferdinand Eduard Polzeniusz patented a process that converts calcium carbide to calcium cyanamide in the presence of 10% calcium chloride at 700 °C. The advantage of lowering the reaction temperature by about 400 °C, however, must be weighed against the high amount of calcium chloride required and the discontinuous process control.
