Annual Report of the Punjab Dry Farming Research Scheme(Rohtak) for the Year 1936-37

It seems however that the effect produced is not only due to the depth of the tillage but due to other factors as well such as the nature of the tilth and the shape of the furrow. [...] (e) Manurial.—The application of farm yard manure increased the yield of bajra significantly and the yields are in the order of the tonnage of the manure applied. [...] Manure also appreciably affected the quantity of water lost from the soil (baring the growth period of the crop and the water lost from the soil to produce the same amount of bajra grain went on decreasing with the increase in the dose of manure applied. [...] Moisture determinations during the fallow period.—In order to find out the effect of these ploughs on the conservation of moisture when the plots remaied fallow after the harvesting of Kharif and Rabi crops soil samples were taken in the month of June before the break of monsoon and moisture estmated. [...] The First Wheat Crop.—During October 1935 there was no rain (except on the last day of the month when a light shower amounting to 0.36 was received) consequently the germination of the first wheat crop sown in the middle of October was poor on account of the low moisture content in the surface soil and the crop had to be resown in November 1935 when a shower of rain was received on the 7th.
