FIELD CROPS. 533 



Lime applied to plats of jute iuvariably produced an increase in yield but a 

 decrease in the value per mauud of the fiber. The greatest increase in value 

 ap]ieared to result from applications of (1) superithosphate and (2) superphos- 

 phate and sa]ti)eter, while the highest yields resulted from very complete mix- 

 tures of artificial and natural fertilizers including lime. 



Other {-rops reported are sugar cane, ground nuts, and papayas.

 In a iiianurial experiment on sugar cane an application of 350 lbs. of nitrogen 

 per acre in castor cake or cow dung gave a higher yield of raw sugar than 

 did an application of 150 lbs. of nitrogen, but the increase was not in proportion 

 to the auurint of manure applied. Owing to the scarcity of the cow manure, 

 it is reconmiended that one-third be replaced by castdr cake, rape cake, safflower 

 cake, or gingelly cake. Applications of saltpeter with the different cakes and 

 bone meal are deemed impracticable unless very cheaply obtained, and appli- 

 cations of 250 lbs. of nitrogen proved uneconomical in all the different forms 

 used. The Poona bed and the trench and furrow systems of planting sur- 

 passed the Raiyat and Mauritius systems. 



On Aman paddy 40 lbs. of nitrogen per acre supplied by most manures is 

 too large an amount to be economical. The highest profits secured were 

 fnmi the use of (1) cow dung and castor cake and (2) sun hemp as a green 

 manure. Losses resulted from the use of (1) castor cake and (2) bone meal 

 and saltpeter. The yield in the case of the latter was even lower tlian when 

 no manure whatever was used. 



Variety tests are reported in connection with cane, paddy, and oats. 



Annual report of the Sibpur Experimental Farm and agricultural classes 

 for 1907-8, S. K. Basu (Ann. h'pt. Sibpiir E.rpt. Fann [India], 1U07-S, pj). 

 10).— In a manurial experiment with rice the highest profits were obtained 

 from the use of dhaincha as a green manure and cow dung applied at the rate 

 of 150 maunds (12,300 lbs.) per acre, while losses resulted from the use of 

 ajiatite and saltpeter, bone meal and saltpeter, mahua cake, and rape cake. 

 With potatoes the highest yield resulted from an application of 300 maunds 

 of cow dung and the lowest from an application of 20 maunds of rape cake. 

 On sugar cane, castor cake, bone meal and saltpeter, and apatite and saltpeter, 

 each ])rodueed a marked increase in yield. 



Seeding of jute seed at the rate of lbs. per acre gave a higher yield of 

 fiber than did the use of TJ ]l)s. Potatoes planted at intervals of 9 in. in 

 rows IS in. apart, produced decisively greater yields than those with I'ows 

 farther apart. Potatoes sprouted in the open air produced decisively higher 

 yields in all cases than did those sprouted under shade, while yields from both 

 whole tubers and cut sets increased as the weight of tubers and sets was 

 increased from 4 oz. each to f oz. and then to 1 oz. each. 



Variety tests are reported with paddy, jute, and sugar cane.

In a variety test of cotton the Peeler and Bailey long staple upland cottons 

 produced the highest yields of seed cotton (about 725 kg. per hectare or (:)45 lbs. 

 yier acre), with lint percentages of 33.99 and 33.07, respectively. Among the 

 4 short staple upland cottons the King variety produced the highest yield, 635.2 

 kg. of seed cotton jier hectare, and also the highest lint jtercentage, .35.26. Only 

 one of tlie 16 long staple ui)land cottons yielded less than 30 per cent of lint to
