Section 79(a) in Rajasthan Land Revenue (Land Records) Rules, 1957
(a)When a crop fails to genninate or dries up or is destroyed by calamities of season, it should be entered as "Kharaba". Very careful attention should be given to the partially failed crops, that is, crops of which the yield appears to be much below average. When the actual yield of the crop grown in one Khasra number is estimated by careful inspection to be not more than 75% of the usual or average yield, then a deduction from the whole area of the crop should be made; for example an inferior fields of wheat measuring 4 bighas may be returned as wheat 3 bighas, Kharaba 1 bigha but this is to be done only when the actual yield of the whole crop is estimated to be not more than 75% of the average, and the "Kharaba" allowed should be only as much as is necessary to raise the whole crop of the area returned as under crop to the average of an ordinary harvest.
