 American sugar planters. Some use only Sulphate of Am- 

 monia for sugar-cane grown after a green-crop (such as, cow- 

 pea) is ploughed in. Sulphate of Ammonia containing over 

 20 per cent. N can be had for Rs. 10 per maund. Sulphate 

 of potash costs about the same. Superphosphate of lime 

 would cost about Rs. 4 per maund.

 thoroughly prepared by deep cultivation, harrowing and rol- 

 ling, and cuttings planted after trenching and watering and 

 when manuring has been done, the intervals between the 

 plants should be given one hoeing with the Hunter hoe after 

 each watering. From March to June four irrigations may be 

 needed. But the need for irrigation depends mainly on the 

 variety of sugar-cane grown, and the time of sowing. If 

 a coarse variety (such as Khari or Kajli) is grown, and if 

 the sowing is done in April (aft^r irrigation), one subsequent 

 irrigation will be found sufficient to bring the plants on. But 

 even in this case two or three hoeings, and one hand weed- 

 ing will be found helpful during May and June, after which 

 nothing need be done till harvest time. To break up the 

 surface pan it is important to do a hoeing after each irriga- 

 tion, the first hoeing should be with hand-tools. The superior 

 varieties of canes that have soft skins are particularly benefited 

 by tying. The tying protects the canes from the 'attack of 

 insect and fungus pests and jackals, and the growth is more' 

 uniform and clean. The opposite practice of ' trashing/ or 

 tearing away the leaves as the canes grow, probably accounts
