formation regarding the decomposition of green manures 

 under varying conditions of — 



(a) Water content of the soil, 



(b) Air content of the soil, 



(c) Age of plant at time of burying, 



(d) Depth of burying, 



and as to the effect of such manures on the condition of the 

 soil. 



Cultivation. — Special investigations as to the value of 

 intertillage by bullock implements in maize and sugar-cane 

 will be undertaken. Correct spacings for maize both as a 

 fodder and grain crop will be studied. 



An improvement in the methods of working the heavier 

 low-lying land appears to be necessary and improved imple- 

 ments will be given a trial. 



Breeding Herd. — The present Montgomery herd is 

 doing satisfactorily, although the milk yield is not as high 

 as might be desired. Owing to the demand for milk from 

 the subordinate staff and the want of budget provision for 

 extensive purchases a rigid selection of the best milking 

 cows has not been possible. This tends to keep down the 

 average yields. Line breeding will be necessary as pedi- 

 gree cattle of this breed are not obtainable in the country. 



Sheep. — The young Gorakhpur Dumbha cross ewes will 

 be used as a foundation for further improvements in wool 

 production. It seems necessary to investigate what type of 

 fleece is the most suitable for sheep in the plains of Northern 

 India, whether a loose coat with a good length of staple or 

 a close fine coat. It is also necessary to regularize and limit 

 the lambing period, to cast the ewes at regular ages, and to 

 employ a more rigid selection as regards wool. 



Pastures. — A study of the agricultural characters of 

 pasture grasses and legumes will be undertaken with a view 

 to the sowing of mixtures instead of pure cultures of duhk. 

 The effect of rolling, harrowing and topping pastures will
