Abstract/ Executive Summary:

A research project with the financial assistance of the BADC was undertaken to study the efficiency of muriate of potash on the yield of wheat In some soils of Bangladesh. Field trials were carried out with Sonalika wheat variety as the test crop. In the experiment, there were ten treatment combinatiaons consisting of 2 rates of N @ 80 and 120 kg N ha and 5 rates of K @ O, 40, 60. 80 and 30+30 (Spilt application) kg K₂0/ha. The experimental results showed that the grain yield of wheat increased significantly due to application of K alone or in combination with N at BAU, Thakurgaon and Netrokona farms.

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

To evaluate the efficiency of muriate of potash fertilizer in cereal production in Bangladesh.

Methodology:

The experiment was carried out at several BADC farms covering major soil types of Bangladesh. Sonalika variety of wheat was selected as the test crop for the experiments. In the experiments, there were ten treatment combinations consisting of 2 rates of N @ 80 and 120 kg N/ha and 5 rates of K @ 0,40,60,80 and 30+30 (split application) kg K₂0/ha with a basal application of P at the rate of 80 kg P₂O₅ /ha. Nitrogen was applied in 3 splits, one third as basal, one third at maximum tillerinq stage and the remaining one third at panicle initiation stage. Potash (only in case of split application) applied one half as basal and the remaining halt at panicle initiation stage. Urea, tripplesuper phosphate and muriate of potash served as the sources of nitrogen, phosphorus and potassium respectively. Fertilizer treatments were replicated thrice. A completely randomized block design was used in the experiment. lndividual plot size was 20 m² .
