Table I, 

 Water saving results obtained at Mirpurkhas, 1916-17.- 



It will be seen that taking all the results in this table 

 together, the extra watering, on the average, not only pro- 

 duced no result but slightly depressed the yield. Taking 

 the results on the light, free-working soils only, the aver- 

 age yield on the preliminary watering comes to 1,535 lb. 

 per acre while that with the extra January irrigation «is 

 only 1,383 lb. per acre. Thus on a soil with good texture, 

 the second irrigation depressed the yield by no less than 

 152 lb. per acre. 



The most striking results on water saving so far 

 obtained in the plains of North- West India were secured 

 by Clarke at the Sugar Experiment Station at Shahjahan- 

 pur in 1919 after the poor monsoon of 1918 (Plate V). 

 The rainfall of June, July and August amounted to SSI -9 

 inches and there was practically no rain during September 

 and October. The wheat (Pusa 12) was sown on natural 

 moisture in October and was irrigated once only in Novem- 

 ber. The cold weather rainfall was 2-63 inches all of 

 which was received in January, 1919. The yields obtained
