manures on the yield, quality, and nicotine content of 

 Indian tobaccos. As regards yield the best results were 

 obtained from farmyard manure, closely followed by a 

 combination of superphosphate and potassium nitrate, 

 whereas neither of the latter manures had any appreciable 

 effect when used alone. The leaf produced from the 

 various plots was submitted to the Director of the Indian 

 Leaf Tobacco Development Company, Dalsing-Sarai, for 

 valuation, and in his opinion no definite relationship was 

 apparent between the manurial treatment given and the 

 quality of leaf produced. Similarly no definite relation- 

 ship was discovered in regard to the nicotine content. 



The relative effect of topping and spiking the plant was 

 also investigated. The yield of plant was practically 

 identical, but the topped plants gave a greater outturn 

 of stalk than the spiked ones. On the other hand, the 

 topped plants yielded a leaf of better texture and a higher 

 nicotine content. 



An investigation contrasting the effect of rack-curing 

 and ground-curing on the composition of the leaf showed 

 that there is a destruction of starch and sugar during the 

 process, but that ground-curing causes a greater reduction 

 of the starch content than does rack-curing and at the same 

 time produces a leaf of higher nicotine content. 



(c) Sugarcane. For several years the effect of storing 

 canes by clamping has been under investigation in the 

 North- West Frontier Province, and the conclusion 

 arrived at was that no deterioration of the juice took place. 

 This has been confirmed during the last cold season, and, 

 in addition, the effect of windrowing cane as practised in 

 Louisiana has been examined.
