With his guidance Dhirubhai Nayak, of Valsad district of Gujarat, had stopped using chemical pesticides and fertilizers and, instead, began using sea weed, which is available from Okha port, Gujarat, between December and April. Approximately 100 gm sea weed is soaked in 500 ml of water for 12 hours. It is then boiled at low temperature for 45 minutes. The resultant decoction is allowed to cool, and then filtered. About 40 L of water is added to the filtrate and sprayed on the crop. This helps increase the yield of the crop. In another technique, dry sea weed, pounded with organic manure and mixed into the soil is also beneficial. It acts rapidly when sprayed as liquid. Moreover, it decomposes within a month. In addition to the above techniques, seeds soaked in water and extract of sea weed are found to germinate earlier. According to the Editor of Honey Bee, Dr Girdharbhai L Atara, Professor at Ayurveda College, Jamnagar, has also conducted many experiments on sea weed, and has developed a unique liquid, called (kunupjal), which can be used as organic manure and contains many nutrients.
