The Forest Department, Arunachal Pradesh has also taken up its cultivation. It can be cultivated by seedlings raised from seed or from wildings. The crop mature in 6-10 years depending upon source of planting materials. Harvesting is done during winter season. On an average 124 kg dry rhizome per hectare is harvested with a spacement of 30 × 30 cm.

The paper describes in detail aerial spraying of cashew plantations in Goa with pesticides to control tea-mosquito, Helopeltis antonii which is a very serious pest of cashew plantations in India, especially on the west coast. It is estimated to reduce the yield of nuts and apples from the plantations to the tune of 30-40%. Aerial spraying was done over an area of 2540 ha of yielding cashew plantations during the pre-and post-flowering period during 1976-77. Dealing with large-sized and well-stocked plantations serial spraying was found more effective and economical or motor-driven sprayers. Due to hilly terrain, helicopter was used with advantage for serial spraying. The pesticides used were thiodon-(endosulfan), and Dimecron-(a phosphamidon). Thiadon is a contact poison; dimecron is both a contact and systemic poison. Both were found equally useful and useful and effective in controling tea-mosquito.- Yield Regulation in the Andaman Forests
