Abstract: | Comparative effects of potassium chloride and potassium sulfate at various levels of potassium on the performance of ARZ variety
of wheat were studied at Agriculture Research Station Dera Ismail Khan, N.W.F.P., Pakistan. The experiment was laid out in
three different rotationsviz, rice-wheat, maize-wheat and fallow-wheat. Potassic fertilizers were applied at the rate of 0, 37, 74, 111 and 148 kg k/ha
alongwith the basal dose of 135 kgN plus 44 kg P/ha.
Wheat yield data showed that the application of 37 kg K/ha of potassium chloride was found better in case of rice-wheat and
fallow-wheat rotation and 37 kg K/ha of potassium sulfate for maize-wheat rotation. On the average of the three rotations,
potassium sulfate at the rate of 74 kg K/ha (90 kg K2O/ha) was found better and economical. Both the sources were almost equally effective but potassium sulfate out-yielded potassium
chloride. Protein content of grains was significantly increased due to K application irrespective of the source and potassium
sulfate was found with significantly higher protein content than potassium chloride. |
