Add to ORKGNo meaningful conclusions can be drawn until the multiple regression analysis comparing soil and plant parameters with level of response has been completed. Similarly it is extremely dangerious to extrapolate results obtained from any one experiement in a particular district to the general farm situation. In addition these results represent only 1 rather atypical season and so need to be verified by additional calibration trials. in 1973 (40) and 1974 (20)
