Last year M. R. Ry. W. Raghavachariar, Farm Manager on special duty, Coimbatore District, informed me that fish manure was good for Sugarcane crop and asked me to use it and, through his in-ducement, I obtained 45 bags of which I used 20 bags for 24 acres of Sugarcane. It cost me Rs. 2 per bag when received in this village.After the application of this manure the crop tillered and grew exceed-ingly well. This year the crops suffered very much owing to severe drought from March to June and owing to insufficient water in the wells. Owing to this circumstance the yield of jaggery per acre was wells. Owing to this circumstance the yield of jaggery per acre was only 30 pothies. But ordinarily if an acre of Sugarcane is manured with 40 Rs. worth of Kolingi leaves and does not suffer for want of irrigation, an yield of 45 pothies of jaggery is obtained. The yield of jaggery is low this year owing to want of supply of sufficient water.If the crop had been manured with 16 Rs worth of Kolingi leaves per acre (just the cost of fish manure), with the same drought as this year, I would not have got any thing over 20 pothies. The most important thing to be attended to by those who use this manure is that they should see that the crop receives irrigation without break and that it is carefully saved even in the summer drought. Several ryots of this village have decided to use this manure liberally for paddy this coming season after seeing the excellent results of this manure on paddy raised by Thenpalani Thevan of Irungår.
Ananthan P.S (Thu,) studied this question.
