ABSTRACT
Wheat is the major staple cereal of the Pakistani people. For healthy growth of field crops potassium (K) is considered an essential element. Potassium activates many enzymatic reactions in plant body. The deficiency of bio-available potassium is pronounced throughout the world. In Pakistan due to dense plantation and minimum use of artificial potassium fertilization the yield and supply potential is diminishing day by day. The cost of potassium fertilization is very high and awareness for external nutrition of potassium benefits is also on the minimum side. To overcome potassium bio-available losses from Pakistani farming system is very essential to sustain crop growth. Keeping in view of these issues, a pot study was performed at the departmental research area. The aim of the research was to depict the efficacy of the use of carbon sequestering fertilizer (compost, press mud and fly ash) along with conventional potassium fertilizers (MOP & SOP) on wheat growth and potassium availability in soil. Carbon sequestering fertilizers were applied @ 0% (Control), 0.5 & 1% of soil weight along with recommended rated of commercial K fertilizers. After the crop was harvested, soil sampling was carried out followed by analysis in the laboratory. It was observed that use of press mud @ Yield 1 % in integration with SOP as chemical K fertilizer performed as best treatment by improving yield (4.11 t/ha) and yield contributing parameters like maximum plant’s height (95.10 cm), length of spike (11.04), number of fertile tillers (5.67), 1000 grains weight (39.26 g) and grain count per spike (51).
