of June and were not completed till July. The pulse crop 

 was consequently sown too late. The shortage of rainfall 

 continued during the monsoon. Two inches of rain in 

 October, however, facilitated the sowing of the rabi (winter) 

 crop. Drought again intervened till February 1920 when 

 rain saved the oat crop from total failure but was too late 

 for straw. The arhdr (Cajanus indicus) crop which was 

 flowering at the time suffered a great deal and yielded dis- 

 appointingly. The monsoon, though light, was not un- 

 favourable to the maize grown for grain, but that grown 

 for green fodder was much below normal. 



The Pusa Farm is worked under a three-year 6-course 

 rotation given below. The land is double-cropped, i.e., two 

 crops are taken off the same land annually. 



Details are as follows : — 



1st years rotation. The land under maize is given 10 

 tons farmyard manure or 10 maunds oil-cake and is fol- 

 lowed by oats in the rabi. During the year under report 

 five fields aggregating 125 acres were put down under 

 maize and juar (Andropogon S or gum). The best yield was 

 got from South Pangarbi field where 15 acres gave 220 

 maunds per acre of green fodder, the best yield of oats 

 being 14^ maunds per acre from Brickfield No. 2. 



The working cost for the year for both kharif and rabi 

 crops in this year of the rotation amounted to Rs. 56-4* per 

 acre and the return to Rs. 88-2, giving a working profit of 

 Rs. 31-14 per acre for the year. 



2nd year's rotation. No manure is given to the crops in 

 the second year of the rotation. As a rule maize and arhar
