6. Green Manuring. — Green manuring has been very 

 successful, especially in the case of lands newly reclaimed 

 from jungle. By green manuring such lands, they are 

 immediately brought into a condition of high fertility, 

 whereas under ordinary conditions moderate fertility is 

 only obtained after two or three years' cultivation. Sann- 

 hemp is a crop ordinarily employed for ploughing in. It 

 grows rapidly and gives a large bulk for ploughing in 

 about the middle of the monsoon, and becomes sufficiently 

 decomposed before the sowing of the succeeding rahi crop 

 to avoid danger of the land drying out from being too 

 loose. The effects of green manuring are very marked in 

 the two following crops and are discernible for two or three 

 crops more. 



7. Permanent Manurial and Rotation Experiments. — 

 These were laid down last year according to the scheme 

 described in the Proceedings of the Board of Agriculture, 

 held in February 1908. It will be after some years only 

 that the results obtained will have their full value. The 

 kharif yields varied, on the whole, very consistently with 

 the doses of manure applied, thus showing that the land 

 selected was sufficiently uniform for the purpose. The 

 rahi sown plots were so poor as in most cases to be incap- 

 able of being harvested. 



8. Permanent Pasture Exferiments. — Owing to the 

 ever-increasing contraction of grazing areas in India, it is 

 of importance to know the best conditions under which 

 good pastures can be established and maintained. That 

 good pastures can be grown in many parts of India there is 

 little doubt. An area of 80 acres of unmanured pasture 

 at Pusa was found sufficient to supply all the green food 

 required by two hundred head of cows and young cattle for 

 six months in the year while yielding quite a substantial 

 amount in the remaining six months. Consequently, a 

 series of permanent pasture experiments was laid down in 

 the monsoon of 1907 according to the scheme described in 

 the Proceedings of the Board of Agriculture, held in
