Fish gunabajalam
What is fish gunabajalam and how is it manufactured?
S. Gopi Chand, Ahmedabad, Gujarat
Fish gunabajalam is an organic nutrient which is sprayed over the crops to increase the chlorophyll content. It is manufactured by adding about 1 kg of fish waste (rotten fish can also be added) and 1 kg of ghur (Pannai vellam in Tamil) in a plastic drum. It is then allowed to remain for about 25 days, after which it is used as a spray by diluting 100 ml of the solution in 10 litres of water. For details contact Dr. G.
