Abstract
Effect of split application of recommended dose of potash on the yield and yield components of rice was studied
at farmer's field in six (6) Districts of traditional rice growing area Le. Gujranwala, Sialkot, Narowal, Lahore,
Hafizabad and Sheikhupura. In this investigation a recommended dose of potash fertilizer (62.5 kglha) was
tested in two treatments i.e. whole Potash as a basal dose and Y2 potash as basal and Y2 potash at 25 DAT that
were compared with the treatment where no potash was applied. Means of paddy yield and yield components of
rice averaged across six districts showed that maximum value of tillers per hill (26.81), grains per panicle (68.81),
1000 grains weight (22.00 g), paddy yield (4.73 t/ha) and minimum percentage of sterile grains (6.39%) were
observed in treatment receiving split use of Potash. Whole of potash applied at transplanting and no potash
application treatment ranked at second and third position respectively with respect to all these parameters. The
increased grain yield of rice with split applying of K was attributed to continuous supply of K during crop growth
period.
